First of all, I use docker under Mac and use a container in docker to install lnmp environment. When the user accesses, when the project obtains the visitor Ip, it will always be a docker bridged ip such as 172.0.0.1, and the client ip will not be available. Google took a long time to solve it. solve
At the same time, I also want to go to the ip of the host. Thank you

The following is the NGINX configuration

listen 80;
 server_name www.nihao.test;
 
 location / {
 proxy_pass http://www.nihao.test;
 proxy_set_header    Host             $host:$server_port;  # Don't forget the port after forwarding
 proxy_set_header    X-Real-IP        $remote_addr;
 proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
 proxy_set_header    HTTP_X_FORWARDED_FOR $remote_addr;  # Key Sentences
 proxy_set_header    X-Forwarded-Proto $scheme;
 proxy_redirect      default;
 
 try_files $uri $uri/ $uri=404;
 }
