Discuz! X 开启https后UCenter通信失败

问题现象：
Discuz! X 开启https后UCenter显示通信失败，通信密钥正确，数据库信息正确

解决方法：
1. 修改文件uc_server/model/misc.php
2. 查找$port = !empty($matches['port'])
3. 在下方插入代码

        if(substr($url,0,5)=='https'){
            //var_dump($url);
            $ch = curl_init($url);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

            if($post){
                curl_setopt($ch, CURLOPT_POST, 1);
                curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
            }

            if($cookie){
                curl_setopt($ch, CURLOPT_COOKIE, $cookie);
            }
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
            return curl_exec($ch);
        }
