nginx反向代理配置如何去除前缀

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         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/表示匹配前缀是user的请求，proxy_pass的结尾有/，则会把/user/*后面的路径直接拼接到后面，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;}
}
