使用具有不同协议(protocol)的代理的 PHP cURL 请求

Question

如果我有 2 个代理:

$proxy1 = array('http', 'XXX.XXX.XXX.XXX','8080') 和 $proxy2 = array('https','YYY.YYY .YYY.YYY','80')

我要求: $url1="http://somesite-1.net" 和 $url2="https://somesite-2.net"

初始化多 curl 的代码:

foreach ($urls as $url) {
            // threads
            $ch = curl_init($url); 
            curl_setopt($ch, CURLOPT_AUTOREFERER, $_autoreferrer);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, $_follow_loc);  
            curl_setopt($ch, CURLOPT_MAXREDIRS, $_max_redirects); 
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    
            curl_setopt($ch, CURLOPT_HEADER, 0);                

            curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $_connection_timeout);                   curl_setopt($ch, CURLOPT_TIMEOUT, $_curl_timeout);  
            curl_setopt($ch, CURLOPT_RETURNTRANSFER,    true);
            curl_setopt($ch, CURLINFO_HTTP_CODE,        true);
            curl_setopt($ch, CURLOPT_PROXY,         $this->conf->getProxyIP().":".$this->conf->getProxyPort());     //PROXY       
            curl_setopt($ch, CURLOPT_USERAGENT,     $this->conf->getUserAgent());                                   
            if($referrer = $this->conf->getReferrer() !== false){                                                   //REFERRER
                curl_setopt($ch, CURLOPT_REFERER, $referrer);
            }



            $tasks[$url] = $ch;

            curl_multi_add_handle($cmh, $ch);
        }

是否需要设置代理协议(protocol)http或https来发送请求？ 因为当我使用套接字检查代理时 - 我收到消息说一切正常并且代理正在工作。但是当我使用 cURL 请求内容时 - 我不是从所有代理获取内容。我认为问题在于未设置代理协议(protocol)。我想我需要在 cURL 中设置一些选项，但不知 Prop 体是什么。
