nginx反代时proxy_pass指向https带域名时的502错误

指向https://域名这样的地址, 通常是要解析的, 解析DNS失败或者证书获取失败都有可能产生502这毛病

所以改造如下:

resolver 223.5.5.5; # 指定域名DNS解析服务器
proxy_ssl_server_name on; #开启ssl主机
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass https://blog.quwei.de; # frps
error_page 502 http://err.quwei.de/$request_uri;
