spring cloud gateway modify response headers03 Apr spring cloud gateway modify response headers
cloudflare tunnel home assistant 19 3407 . To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. Embed. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. You can also define a rate limiter as a bean that implements the RateLimiter interface. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). or check if an exchange has already been routed. These are special filters that are conditionally applied to all routes. You can combine multiple route predicate factories with logical and statements. forwards the incoming token to outgoing resource requests. You can use it inside a regular Spring web handler as a method parameter. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. I got the root cause. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. For example, to reference a filter named Something in configuration files, the filter APIcast standard policies This strips the service ID from the path before the request is sent downstream. This predicate matches with a header that has the given name whose value matches the regular expression. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. If youre using load-balanced routes, you need to explicitly define your. Removes an existing route from the gateway. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. SetResponseHeader is aware of URI variables used to match a path or host. The algorithm used is the Token Bucket Algorithm. returned from the route it wraps. .filters(f -> f.addRequestHeader("header1", "header-value-1")) extracts an access token from the currently authenticated user, For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. Here, you can modify requests and responses before or after sending the downstream request. With MVC, it also supports forwarding to a local handler through the forward() method. If you would like us to look at this issue, please provide the requested information. response-timeout must be specified as a java.time.Duration. You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. Code Revisions 1 Stars 14 Forks 3. Predicate: This is a Java 8 Function Predicate. If You Appreciate This, You Can Consider: We are thankful for your never ending support. must be in a class named SomethingGatewayFilterFactory. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium The first one is the The redis-rate-limiter.requestedTokens property is how many tokens a request costs. It adds the Host header, scheme and port of the current request to any existing Forwarded header. A utility method (called get) is available to make access to these variables easier. Service 4.3. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. This paper will introduce its usage in detail. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. The following listing shows how it works: This style also allows for more custom predicate assertions. Sharing Routes between multiple Gateway instances, 17.1. The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. Well occasionally send you account related emails. consumer can be a pure Client (like an SSO application) or a Resource The following example configures an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. By default, if the KeyResolver does not find a key, requests are denied. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. The gateway maintains a client pool that it uses to route to backends. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. This is the rate at which the token bucket is filled. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. You can read more about them in the. Since the request can be read only once, we need to cache the request body. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. status codes you want to trip the circuit breaker you can either use an integer with the status code AddRequestParameter is aware of the URI variables used to match a path or host. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. The DedupeResponseHeader filter also accepts an optional strategy parameter. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. Currently, only forward: schemed URIs are supported. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. httpMethod: The HTTP method used for the request. Modify request body. The default filter is a rewrite path filter with the regex /serviceId/?(?. Spring cloud gateway response body modification. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. It must be a valid Spring HttpStatus. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. Route: The basic building block of the gateway. This filter works only with HTTP (including HTTPS) requests. If so, the same rules apply. The path part of the request URL is overridden with the path in the forward URL. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. The args key is a map of key value pairs to configure the predicate or filter. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). It runs after all other filters have completed and writes the proxy response back to the gateway client response. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. This is the value of the Location header. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. This interface and its usage are subject to change in future milestone releases. While a Gateway is running you can use kubectl scale to modify the number of replicas. and puts it in a request header for the downstream requests. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The RemoveHopByHop Headers Filter removes headers from forwarded requests. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. Value 3.9. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. return r.host("*.somehost.org").and().path("/somepath") The pattern is an Ant-style pattern with . Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? keyResolver is a bean that implements the KeyResolver interface. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). URI variables may be used in the value and are expanded at runtime. This predicate matches requests that happen after datetime1 and before datetime2. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). If the new named header already exists, its values are augmented with the new values. Setting this value to zero blocks all requests. How does it work? Note that the null value is due to an incomplete implementation of the endpoint controller, because it tries to set the order of the object in the filter chain, which does not apply to a GatewayFilter factory object. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. GatewaySampleApplication.java. This predicate matches requests that happen before the specified datetime. Route filters are scoped to a particular route. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. The To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Note that the $ should be replaced with $\ because of the YAML specification. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. Those values are then available for use by GatewayFilter factories. You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. privacy statement. Configuring Predicates and Filters For, 15.4. That is not a complete working sample, it is just some code. URI variables may be used in the value and are expanded at runtime. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. URI variables may be used in the value and are expanded at runtime. The PreserveHostHeader GatewayFilter factory has no parameters. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. Cleanliness 4.4. This is the number of tokens taken from the bucket for each request and defaults to 1. In some cases you might want to trip a circuit breaker based on the status code It is the name of the header to be removed. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. The datetime2 parameter must be after datetime1. The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). The RemoveResponseHeader GatewayFilter factory takes a name parameter. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. You must use $\ to mean $ because of the YAML specification. This handler runs the request through a filter chain that is specific to the request. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. Let's simplify this scenario. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. For relative redirects, you should use uri: no://op as the uri of your route definition. Have a question about this project? The arguments are typically listed in the order that are needed for the shortcut configuration. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. Easy to extend and/or customize using standard Spring patterns The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. To configure Global http timeouts: 25Modify Response Body GatewayFilter Factory; The preceding route matches if the request contained a red query parameter whose value matched the gree. The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. .metadata(RESPONSE_TIMEOUT_ATTR, 200) The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. Multiple matching segments are allowed. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. }, 4. Spring Cloud supports Resilience4J out of the box. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. It offers a simple way to manipulate the request path by allowing templated segments of the path. I think i have to go for a blocking call here. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. Naming Custom Filters And References In Configuration, 18. The name and argument names are listed as code in the first sentence or two of each section. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. There is an abstract class called AbstractRoutePredicateFactory which you can extend. For example, given a Gateway that has 1 replica, the following will . This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. The following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. httpStatusCode: The HTTP Status of the request returned to the client. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. Fork 3. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Some situations necessitate reading the request body. Filter: These are instances of GatewayFilter that have been constructed with a specific factory. It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The default list of headers that is removed comes from the IETF. The RemoteAddr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). The following example configures a method route predicate: This route matches if the request method was a GET or a POST. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. AddRequestHeader is aware of the URI variables used to match a path or host. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. Typically, there will be a name key and an args key. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. This is the number of tokens the token bucket can hold. It is the permissible size limit of the request defined in bytes. Zuul profile. 1. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments.
