nginx配置代理

提醒：本文最后更新于 1749 天前，文中所描述的信息可能已发生改变，请谨慎使用。

出于某些原因，我们要使用自己的域名去代理某个网站，当访问自己的网站域名时，出现的内容是想真实访问的网站内容，这个时候就需要配置代理了。这里以nginx为例，我自己参照网上的教程配置了一个，仅供参考：

server {
	listen 80;
	server_name www.yourdomain.com;
	return 301 https://$host$request_uri;
	location / {
		proxy_pass    https://www.proxydomain.com;			
		sub_filter    www.proxydomain.com   www.yourdomain.com;
		sub_filter_once                     off;			
		proxy_http_version                  1.1;
		proxy_cache_bypass                  $http_upgrade;
		proxy_set_header Upgrade            $http_upgrade;
		proxy_set_header Connection         "upgrade";
		proxy_set_header Referer            https://www.proxydomain.com;
		proxy_set_header Host               www.proxydomain.com;
		proxy_set_header X-Real-IP          $remote_addr;
		proxy_set_header X-Forwarded-For    $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Host   $host;
		proxy_set_header X-Forwarded-Proto  $scheme;
		proxy_set_header X-Forwarded-Port   $server_port;
		proxy_set_header Accept-Encoding    "";
	}
	access_log off;
}
