spring cloud gateway和nigix 路由转发时携带域名头信息

1.nigin添加一段配置

  server {
        listen 80; # this is the key !!!!!   proxy_set_header Host $host; location /client/pids { proxy_pass http://10.103.13.103:3200/client/pids; } location /interface/client/pids { proxy_pass http://10.103.13.103:3200/interface/client/pids; } ......

2.gateway网关配置

有一个过滤器PreserveHostHeaderGatewayFilter，用来在gateway转发请求的时候把原始请求的host头部带上，转发给目标服务。

- id: auth-service
  uri: lb://auth-service
  predicates:
    - Path=/api/auth/**,/api/oauth/dd/**
  filters:
    - StripPrefix=1
    - PreserveHostHeader #发送网关原始主机头:
