nginx - Nginx将子域转换为路径组件而无需重定向

Question

这个想法是将传入请求接收到http://abc.example.com/...并将其重写为http://example.com/abc/...
使用301/302重定向很容易做到:

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

诀窍是当abc.example.com和example.com指向同一Nginx实例时，将URL透明更改为客户端的。

换句话说，Nginx是否可以在请求example.com/abc/...和时提供abc.example.com/...中的内容，而无需其他客户端往返？

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;
  }
}
