Nginx reverse proxy configuration to remove prefix case tutorial

When using nginx as a reverse proxy, you can simply forward the request to the next service intact. Setting the proxy_pass request will only replace the domain name. If you want to access different services based on different URL suffixes, you need to use the following method:

Method 1: Add "/"

server {
    listen 8000;
    server_name abc.com;
    access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main;

    location ^~/user/ {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://user/;
    }

    location ^~/order/ {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://order/;
    }
}

^~/user/ means matching requests with the prefix user. If there is a / at the end of proxy_pass, the path after /user/* will be directly concatenated to the end, that is, user will be removed.

Method 2: rewrite

upstream user
  server localhost:8089 weight=5;
}
upstream order
  server localhost:8090 weight=5;
}

server {
    listen 80;
    server_name abc.com;
    access_log "pipe:rollback /data/log/nginx/access.log interval=1d baknum=7 maxsize=1G" main;

    location ^~/user/ {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/user/(.*)$ /$1 break;
        proxy_pass http://user;
    }

    location ^~/order/ {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;

        rewrite ^/order/(.*)$ /$1 break;
        proxy_pass http://order;
    }
}

There is no / at the end of proxy_pass, and rewrite rewrites the URL.
