Nginx反向代理配置去除前缀

前言

使用nginx做反向代理的时候，可以简单的直接把请求原封不动的转发给下一个服务。设置proxy_pass请求只会替换域名，如果要根据不同的url后缀来访问不同的服务，则需要通过如下方法：

方法一：加"/""

server {
    listen              8000;
    server_name         demo.gmit.vip;
    access_log  "pipe:rollback /home/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/;
    }
}

方法二：rewrite

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

server {
    listen              80;
    server_name  www.gmit.vip;
    access_log  "pipe:rollback /home/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;
    }
}
