nginx反向代理配置如何去除前綴

使用nginx做反向代理的時候，可以簡單的直接把請求原封不動的轉發給下一個服務。設置proxy_pass請求只會替換域名，如果要根據不同的url后綴來訪問不同的服務，則需要通過如下方法：

方法一：加"/"**

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/表示匹配前綴是user的請求，proxy_pass的結尾有/，則會把/user/*后面的路徑直接拼接到后面，即移除user。

方法二：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;}
}
