RemoveRequestParameter 過濾器

RemoveRequestParameter 過濾器接受一個 name 引數。它是要移除的查詢引數的名稱。以下示例配置了一個 RemoveRequestParameter 過濾器

application.yml
spring:
  cloud:
    gateway:
      mvc:
        routes:
        - id: removerequestparameter_route
          uri: https://example.org
          predicates:
          - Path=/**
          filters:
          - RemoveRequestParameter=red
GatewaySampleApplication.java
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.uri;
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.removeRequestParameter;
import static org.springframework.cloud.gateway.server.mvc.handler.GatewayRouterFunctions.route;
import static org.springframework.cloud.gateway.server.mvc.handler.HandlerFunctions.http;

@Configuration
class RouteConfiguration {

    @Bean
    public RouterFunction<ServerResponse> gatewayRouterFunctionsRemoveRequestParameter() {
        return route("removerequestparameter_route")
            .GET("/**", http())
            .before(uri("https://example.org"))
            .before(removeRequestParameter("red"))
            .build();
    }
}

這將在引數傳送到下游之前移除 red 引數。
