图片3为什么访问报错

Answer 1

proxy_pass

A request URI is passed to the server as follows:

• If the proxy_pass directive is specified with a URI, then when a request is passed to the server, the part of a normalized request URI matching the location is replaced by a URI specified in the directive

location /name/ {
    proxy_pass http://127.0.0.1/remote/;
}

• If proxy_pass is specified without a URI, the request URI is passed to the server in the same form as sent by a client when the original request is processed, or the full normalized request URI is passed when processing the changed URI:

location /some/path/ {
    proxy_pass http://127.0.0.1;
}

Answer 2

你的配置问题， proxy_pass http://110.42.139.52:9080/nginx_demo/a/
