spring cloud gateway modify response headers

{githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] 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 requires the Netty runtime provided by Spring Boot and Spring Webflux. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. Configuring Predicates and Filters For, 15.4. In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts results in dropped requests (HTTP 429 - Too Many Requests). By default, if the KeyResolver does not find a key, requests are denied. Sign in The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. AddResponseHeader is aware of URI variables used to match a path or host. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) .filters(f -> f.addRequestHeader("header1", "header-value-1")) URI variables may be used in the value and are expanded at runtime. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. This interface and its usage are subject to change in future milestone releases. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. It uses the Netty HttpClient to make the downstream proxy request. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. The first one is the In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. The lowercase full name of the secure header needs to be used to disable it.. 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). The route configuration allows applying CORS directly to a route as metadata with key cors. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. A per-route response-timeout with a negative value will disable the global response-timeout value. Cleanliness 4.4. With MVC, it also supports forwarding to a local handler through the forward() method. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. 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. Most examples below use the shortcut way. Tripping The Circuit Breaker On Status Codes, 12.4.1. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium Once a request has been marked as routed, other routing filters will not route the request again, This handler runs the request through a filter chain that is specific to the request. The ServerHttpResponse instance is used to . If it is not provided, the value of the Host request header is used. We do this already For example, you can match on the path segment of the URL or the HTTP method of the request. 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 following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). it is proxying. 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 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)'. Those values are then available for use by GatewayFilter factories. Spring Cloud supports Resilience4J out of the box. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. Policy to specify how to modify the response code, body and headers. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. 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. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. This filter works only with HTTP (including HTTPS) requests. So a request to /hello is sent to /mypath/hello. This strips the service ID from the path before the request is sent downstream. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. AddRequestParameter is aware of the URI variables used to match a path or host. 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 The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. I got the root cause. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. 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). Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. 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. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. 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. 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 following listing shows how it works: This style also allows for more custom predicate assertions. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. The So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. It is the permissible size limit of the request defined in bytes. The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. There are convenience methods that you can use to mark an exchange as routed 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). The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. Multiple matching segments are allowed. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. Star 14. Download ZIP. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. connect-timeout must be specified in milliseconds. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). response Header Transformations: . (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled Easy to extend and/or customize using standard Spring patterns Spring cloud gateway response body modification. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. For a full working sample see this project. To clear the routes cache, make a POST request to /actuator/gateway/refresh. GitHub Gist: instantly share code, notes, and snippets. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. To configure per-route timeouts: The XForwarded Remote Addr Route Predicate Factory, 6.5.1. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. This uses the URI templates from Spring Framework. 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. responseCode; responseHeaderTransformations; responseMessage; type; . The RemoveRequestHeader GatewayFilter factory takes a name parameter. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. This filter can be configured only by using the Java DSL. Easy to extend and/or customize using standard Spring patterns The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. It is the name of the header to be removed. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. That is not a complete working sample, it is just some code. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. This can be used with reverse proxies such as load balancers or web application firewalls where Spring cloud gateway response body modification. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. To disable it, set the following property: This will default to true in a future release. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. This is the number of tokens the token bucket can hold. Route: The basic building block of the gateway. backoff: The configured exponential backoff for the retries. Any otherway is there apart from blocking call? The args key is a map of key value pairs to configure the predicate or filter. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). Retrieving Information about a Particular Route, 15.6. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. It is the name of the header to be removed. You can read more about them in the. If it is not matched, the filter does nothing. Add a response header named X-Request-Foo with a value of Bar to the original response. Want to remove the "warning cannot modify header information" error from your WordPress website? To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? 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. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. How does it work? Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. The SetRequestHeader GatewayFilter factory takes name and value parameters. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. URI variables may be used in the value and are expanded at runtime. Configure for High Availability. The DedupeResponseHeader filter also accepts an optional strategy parameter. Displays the list of routes defined in the gateway. The RequestRateLimiter is not configurable with the "shortcut" notation. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. Retrieving the Routes Defined in the Gateway, 15.5. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. The maxSize parameter is the maximum data size allowed by the request header (including key and value). In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. Each item defines the name and the arguments of a given predicate. This is the value of the Location header. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. application.yml. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Predicate: This is a Java 8 Function Predicate. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. Have a question about this project? The default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). 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. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. Fork 3. SetResponseHeader is aware of URI variables used to match a path or host. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. These are basic guides to writing some custom components of the gateway. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/1/ or /red/blue or /blue/green. So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. . This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int).
