Nginx reverse proxy configuration removes prefix

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 proxy_pass ends with / , 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.
