Spring Cloud AddRequestHeader GatewayFilter工厂

AddRequestHeader GatewayFilter工厂采用name和value参数。

application.yml。 

spring:
  cloud:
    gateway:
      routes:
      - id: add_request_header_route
        uri: https://example.org
        filters:
        - AddRequestHeader=X-Request-Foo, Bar

这会将X-Request-Foo:Bar标头添加到所有匹配请求的下游请求标头中。

AddRequestHeader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。
