Nginx将子域转换为路径组件而不重定向

Question

我们的想法是将传入的请求转发http://abc.example.com/...并重写为http://example.com/abc/...

这很容易做到301/302重定向:

# rewrite via 301 Moved Permanently
server {
  listen 80;
  server_name abc.example.com;
  rewrite ^ $scheme://example.com/abc$request_uri permanent;
}

关键是要做到这一点URL变化透明的客户端时abc.example.com,并example.com点于同一Nginx的实例.

换句话说,Nginx可以在请求example.com/abc/...时提供内容,abc.example.com/...而无需另外客户往返吗？

起点配置

使用301完成任务的Nginx配置:

# abc.example.com
server {
  listen 80;
  server_name abc.example.com;
  rewrite ^ $scheme://example.com/abc$request_uri permanent;
}

# example.com
server {
  listen 80;
  server_name example.com;
  location / { 
    # ...
  }
}

Answer 1

# abc.example.com
server {
  listen 80;
  server_name abc.example.com;
  location / {
    proxy_pass http://127.0.0.1/abc$request_uri;
    proxy_set_header Host example.com;
  }
}
