nginx反向代理配置去除前綴

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後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/*後面的路徑直接拼接到後面，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;
}

}

proxy_pass結尾沒有/， rewrite重寫了url。
