其实很简单，使用nginx的反向代理就可以解决

1.建立一个站点A用于做代理

2. 将要访问的目标站点B以get参数传入A站点的url
   3.nginx接收参数并重定向到B站点

以下是nginx配置

#PROXY-START/
location  ~* \.(php|jsp|cgi|asp|aspx)$
{
    proxy_pass http://www.baidu.com;
    proxy_set_header Host www.baidu.com;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
}
location /
{
    proxy_pass http://www.baidu.com;
    proxy_set_header Host www.baidu.com;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    
    add_header X-Cache $upstream_cache_status;
    
    #Set Nginx Cache
    
    
    proxy_ignore_headers Set-Cookie Cache-Control expires;
    proxy_cache cache_one;
    proxy_cache_key $host$uri$is_args$args;
    proxy_cache_valid 200 304 301 302 1m;
    expires 12h;
}
resolver 8.8.8.8; # 这句要加上  要不然会报403
location ~/video {
      if ($query_string ~*  ^(.*)url=(.*)$){  # 接收url参数
           set $videoUrl $2;
           proxy_pass $videoUrl;
      }
}
#PROXY-END/

小伙伴们自行配置测试吧
