通过Nginx(OpenResty)修改UserAgent

 

通过OpenResty修改UserAgent,非常简单,Demo里做了多次反向代理是为了日志输出显示效果。实际应用中不必这么麻烦。

浏览器访问如下地址即可

http://127.0.0.1:10090/

 

 

话不多说,直接上配置

upstream webapi_mydemo1{
  server 127.0.0.1:10092;
}

upstream webapi_mydemo2{
  server 127.0.0.1:10093;
}

server {
  listen 10093;

  location / {
    content_by_lua_block{
      ngx.print(“HelloWorld”)
    }
  }
}

server {
  listen 10092;
  set $newagentheader $http_user_agent;

  location / {
    access_by_lua_block{
      ngx.var.newagentheader =”MyDemo Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko
    }
    proxy_pass http://webapi_mydemo2;
    proxy_set_header User-Agent $newagentheader;
  }
}

server {
  listen 10090;
  set $newagentheader $http_user_agent;
  location / {
    proxy_pass http://webapi_mydemo1;
    proxy_set_header User-Agent $newagentheader;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}
