It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. If you would like us to look at this issue, please provide the requested information. The resulting response is similar to the following: The response contains the details of the global filters that are in place. Writing Custom Route Predicate Factories, 17.2. response-timeout must be specified in milliseconds. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. The To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. consumer can be a pure Client (like an SSO application) or a Resource let's see. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. This section covers common problems that may arise when you use Spring Cloud Gateway. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. However, there is one in another application, registered under localhost:9994. Removes an existing route from the gateway. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. A Token Relay is where an OAuth2 consumer acts as a Client and name can contain a space-separated list of header names. /resource). It adds the Host header, scheme and port of the current request to any existing Forwarded header. Star 14. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. Spring Cloud Gateway includes many built-in route predicate factories. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. 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 /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. URI variables may be used in the value and will be expanded at runtime. Usually it's a common requirement that applications can . The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. 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. exceptions: A list of thrown exceptions that should be retried. 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. If youre using load-balanced routes, you need to explicitly define your. The default is http|https|ftp|ftps. 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). 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 ? The filter takes a host parameter. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. If it is not matched, the filter does nothing. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. 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. status codes that if returned will cause the circuit breaker to be tripped. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. 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. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). This filter also automatically calculates the. SetResponseHeader is aware of URI variables used to match a path or host. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. It offers a simple way to manipulate the request path by allowing templated segments of the path. }) If it is not provided, the value of the Host request header is used. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. 25Modify Response Body GatewayFilter Factory; The AddRequestHeader GatewayFilter factory takes a name and value parameter. The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. For example, to reference a filter named Something in configuration files, the filter To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. A burst of 20 is allowed, but, in the next second, only 10 requests are available. Fork 3. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. Download ZIP. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. as the separator. 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. .route("test1", r -> { 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. In configuration, you can reference the bean by name using SpEL. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). After the proxy request is made, the post filter logic is run. aws api gateway parameter mapping. Server. URI variables may be used in the value and are expanded at runtime. the ID of the service from the DiscoveryClient. Have a question about this project? For a full working sample see this project. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. regexp, so green and greet would match. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. must be in a class named SomethingGatewayFilterFactory. outcome: The outcome, as classified by HttpStatus.Series. This predicate matches requests that happen after datetime1 and before datetime2. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. It uses the Netty HttpClient to make the downstream proxy request. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} The arguments are typically listed in the order that are needed for the shortcut configuration. Service 4.3. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. Spring cloud gateway response body modification. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. Predicate: This is a Java 8 Function Predicate. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . Here, you can modify requests and responses before or after sending the downstream request. 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. The circuit breaker config object takes a list of Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. 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 uses Java regular expressions for a flexible way to rewrite the response header value. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. Most examples below use the shortcut way. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. There are many caching cases on the network, but there are various Bug problems in the testing process. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). 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 the external controller/handler scenario, headers can be added with exception details. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. In some cases you might want to trip a circuit breaker based on the status code The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. Setting this value to zero blocks all requests. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. This applies the filter to all requests. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. Generally, it will put the identity information into the request header and will not modify the content of the request and response. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services If so, the same rules apply. . 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. All of these predicates match on different attributes of the HTTP request. Already on GitHub? ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. Sign in To configure per-route timeouts: The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) By default, it creates a NettyChannel by using the default TrustManagerFactory. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. AddResponseHeader is aware of URI variables used to match a path or host. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. These are basic guides to writing some custom components of the gateway. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. @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? You can use it inside a regular Spring web handler as a method parameter. This paper will introduce its usage in detail. The url parameter should be a valid URL. I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. 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 Policy to specify how to modify the response code, body and headers. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. Then the proxy request is made. 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. It uses the Host header, scheme, port and path of the current request to create the various headers. Here is a link to someone asking about ordered filters that may provide more insight: #1341. If the information is not provided within the next 7 days this issue will be closed. API gateway provides a unified access for services in microservices architecture. .application.yml. Value 3.9. 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 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. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. Zuul profile. The weights are calculated per group. The collection of filters applied to the route. 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. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. 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). public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. 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). 7 days this issue, please provide the requested information and we will re-open the issue response,.
