运维：Nginx Location if语句中proxy_pass 不支持/context 虚拟路径的解决方案。

请看官方的说明，你可以找到思路 ^_^

A special case is using variables in the proxy_pass statement: The requested URL is not used and you are fully responsible to construct the target URL yourself.

This means, the following is not what you want for rewriting into a zope virtual host monster, as it will proxy always to the same URL (within one server specification):

location / {
  proxy_pass   http://127.0.0.1:8080/VirtualHostBase/https/$server_name:443/some/path/VirtualHostRoot;
}

Instead use a combination of rewrite and proxy_pass:

location / {
  rewrite ^(.*)$ /VirtualHostBase/https/$server_name:443/some/path/VirtualHostRoot$1 break;
  proxy_pass   http://127.0.0.1:8080;
}
