proxy_pass

Sets the protocol and address of a proxied server and an optional URI to which a location should be mapped. As a protocol, “http” or “https” can be specified. The address can be specified as a domain name or IP address, and an optional port:

proxy_pass http://localhost:8000/uri/;

or as a UNIX-domain socket path specified after the word “unix” and enclosed in colons:

proxy_pass http://unix:/tmp/backend.socket:/uri/;

If a domain name resolves to several addresses, all of them will be used in a round-robin fashion. In addition, an address can be specified as a server group.

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:

也就是：http://127.0.0.1/name/ --> http://127.0.0.1/remote/

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:

如果 proxy_pass 中没有添加 URI，那么请求 URI 会传递过去，请求是什么就是什么。

也就是： http://127.0.0.1/some/path/ --> http://127.0.0.1/some/path/

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

Before version 1.1.12, if proxy_pass is specified without a URI, the original request URI might be passed instead of the changed URI in some cases.
