Spring Cloud AddRequestParameter GatewayFilter工厂

AddRequestParameter GatewayFilter工厂采用name和value参数。

application.yml。 

spring:
  cloud:
    gateway:
      routes:
      - id: add_request_parameter_route
        uri: https://example.org
        filters:
        - AddRequestParameter=foo, bar

这会将foo=bar添加到所有匹配请求的下游请求的查询字符串中。

AddRequestParameter知道用于匹配路径或主机的URI变量。URI变量可用于该值，并将在运行时扩展。

application.yml。 

spring:

        predicates:
        - Host: {segment}.myhost.org
        filters:
        - AddRequestParameter=foo, bar-{segment}
