解决方案：

location /wechat_sroa {
           proxy_pass http://127.0.0.1:8080/wechat_sroa/;
           server_name_in_redirect off;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_hide_header  X-Powered-By;
           }
