Let's simplify this scenario. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. None of the prior documentation applies to what follows. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. After the proxy request is made, the post filter logic is run. keyResolver is a bean that implements the KeyResolver interface. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). 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. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. Code Revisions 1 Stars 14 Forks 3. backoff: The configured exponential backoff for the retries. 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. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. A burst of 20 is allowed, but, in the next second, only 10 requests are available. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. Generally, it will put the identity information into the request header and will not modify the content of the request and response. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. The Configure for High Availability. Fork 3. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. status codes you want to trip the circuit breaker you can either use an integer with the status code 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). (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. The args key is a map of key value pairs to configure the predicate or filter. 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 . The body is cached in a request attribute defined by. This predicate extracts the URI template variables (such as sub, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. While a Gateway is running you can use kubectl scale to modify the number of replicas. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. 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 The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Spring Cloud Gateway. 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. Created 6 years ago. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. It offers a simple way to manipulate the request path by allowing templated segments of the path. 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. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. 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. CircuitBreaker also supports URI variables in the fallbackUri. I think i have to go for a blocking call here. 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.) The following listing shows how it works: This style also allows for more custom predicate assertions. The following describes an alternative style gateway. 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). Those values are then available for use by GatewayFilter factories. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. The DedupeResponseHeader filter also accepts an optional strategy parameter. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. Tripping The Circuit Breaker On Status Codes, 12.4.1. You can use it inside a regular Spring web handler as a method parameter. and puts it in a request header for the downstream requests. Options. You can add headers to the downstream response by using the header() methods on ProxyExchange. 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'. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. Spring Cloud Gateway includes many built-in route predicate factories. responseCode; responseHeaderTransformations; responseMessage; type; . This applies the filter to all requests. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. application.yml. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. 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. 25Modify Response Body GatewayFilter Factory; NEVER_STRIP: The version is not stripped, even if the original request path contains no version. There are many caching cases on the network, but there are various Bug problems in the testing process. Each item defines the name and the arguments of a given predicate. In some cases you might want to trip a circuit breaker based on the status code Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. 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. Spring Cloud supports Resilience4J out of the box. The first one is the In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. the ID of the service from the DiscoveryClient. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. 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). }, 4. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. 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. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This is the value of the Location header. SetRequestHeader is aware of URI variables used to match a path or host. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. It does not work in a traditional Servlet Container or when built as a WAR. to the exchange attributes. AddResponseHeader is aware of URI variables used to match a path or host. Spring cloud gateway response body modification. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. *) and the replacement /${remaining}. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$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]. pass the authentication token downstream to the services (in this case ServerHttpResponse interface. This predicate matches requests that happen after datetime1 and before datetime2. We do this already return r.host("*.somehost.org").and().path("/somepath") The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). application.yml. Displays the list of GatewayFilter factories applied to a particular route. To clear the routes cache, make a POST request to /actuator/gateway/refresh. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). SetResponseHeader is aware of URI variables used to match a path or host. .route("test1", r -> { When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. 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. 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 a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. Those values are then available for use by GatewayFilter factories. Displays information about a particular route. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The circuit breaker config object takes a list of Predicate: This is a Java 8 Function Predicate. Removes an existing route from the gateway. These are special filters that are conditionally applied to all routes. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. This could be useful for maintenance windows. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. Retrieving the Routes Defined in the Gateway, 15.5. .metadata(CONNECT_TIMEOUT_ATTR, 200); The pile of explanations in front of Xinchen still don . 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). CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. The status parameter should be a 300 series redirect HTTP code, such as 301. Download ZIP. Well occasionally send you account related emails. There should be no reason why a filter cannot modify a response header. .filters(f -> f.addRequestHeader("header1", "header-value-1")) When setting the The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The route configuration allows applying CORS directly to a route as metadata with key cors. All of these predicates match on different attributes of the HTTP request. For relative redirects, you should use uri: no://op as the uri of your route definition. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. With MVC, it also supports forwarding to a local handler through the forward() method. A Token Relay is where an OAuth2 consumer acts as a Client and 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. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Usually it's a common requirement that applications can . The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. It must be a Java System Property, not a Spring Boot property. You can extend an abstract class called AbstractGatewayFilterFactory. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. It adds the Host header, scheme and port of the current request to any existing Forwarded header. You must use $\ to mean $ because of the YAML specification. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. 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. Sign in Multiple matching segments are allowed. as the separator. This can be used with reverse proxies such as load balancers or web application firewalls where reverse proxies. Modify request body. 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 it is not provided, the value of the Host request header is used. Modifying the Way Remote Addresses Are Resolved, 5.12. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. It runs after all other filters have completed and writes the proxy response back to the gateway client response. 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.
