Nginx代理proxy pass配置去除前缀

使用Nginx做代理的时候，可以简单的直接把请求原封不动的转发给下一个服务。

比如，访问abc.com/appv2/a/b.html, 要求转发到localhost:8088/appv2/a/b.html

简单配置如下：

upstream one {
server localhost:8088 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 / {
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://one;
}

}

即，设置

proxy_pass

但很多时候，我们需要根据url的前缀转发到不同的服务。

比如

abc.com/user/profile.html转发到 用户服务localhost:8089/profile.html

abc.com/order/details.html转发到 订单服务 localhost:8090/details.html

即，url的前缀对下游的服务是不需要的，除非下游服务添加context-path, 但很多时候我们并不喜欢加这个。如果Nginx转发的时候，把这个前缀去掉就好了。

一个种方案是proxy_pass后面加根路径

/

.

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;

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/

user

/

/user/*

另一种方案是使用

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;
}

}

注意到proxy_pass结尾没有

/

rewrite
