是否可以将NGinx配置为对外部资源的代理？

标签： nginx

我有一个无法访问Internet的客户端。我需要更新它。该客户端已连接到我的有权访问@的计算机。 由于我已经在DOCKER容器中运行了NGINX，因此我尝试将其配置为将来自客户端的请求转发到@。

在客户端上，我尝试curl --proxy http://10.222.8.111:80 http://pkg.adfinis-sygroup.ch/centos/7.6.1810/os/x86_64/repodata/repomd.xml 从客户端看到的我的机器地址是10.222.8.111。

这是最后一个nginx配置，我尝试过：

if ($reseauTD) {
     rewrite ^(.*)$ /PROXY/$1;
}

location /PROXY/ {
        error_log /tmp/squid-error.log debug;
        access_log /tmp/squid-access.log;
        rewrite ^/PROXY/(.*)$  $1 break;
        resolver 8.8.8.8  ipv6=off ;
        proxy_pass  http://$http_host$uri$is_args$args:80;
        proxy_set_header Host $proxy_host;
        proxy_set_header X-Real-IP A.B.C.D;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_redirect off;
}

A.B.C.D是我的机器的外部地址。 resseauTD在nginx.conf中定义为：

   geo $reseauTD {
        default         0;
        10.225.200.0/24 1;
        10.239.102.0/24 1;
        10.229.85.0/24  1;
        10.233.1.0/24   1;
        10.229.88.0/24  1;
    }

每次我在客户端上尝试curl命令时，都会在/tmp/squid-error.log文件中看到：
