1. Method#multiRequest 接收需要处理的信息

这里的参数是我们所需要的处理的URL地址及其它信息。

/**
 * @param array ('key' => array())
 * You can find 'key' inside of @method getApiMap
 * array('someMethodKey'=>array('url' => '', 
 *         'requestData' => 'post data', 
 *         'otherData' => 'some other data',
 *         'curlOptions' => array())));
 */
    
public function multiRequest($array)
{
    foreach($array as $k=>&$v) {
        $v['url'] = $this->getApiURL($k);
    }
    return $this->_handleMultiResponse($this->_sendMultiRequest($array));
}

2. Method#_sendMultiRequest()

/**
     * Send multi request at same time
     * @param array $data (
     * array('url' => '', 
     *         'requestData' => 'post data', 
     *         'otherData' => 'some other data',
     *         'curlOptions' => array()));
     */
    private function _sendMultiRequest(array $data)
    {
        $this->_logMultiRequest($data);
        $conn = array();
        //create the multiple cURL handle
        $mh = curl_multi_init();
        $_options = array(
            CURLOPT_HEADER => false,
            CURLOPT_POST => true,
            CURLOPT_CONNECTTIMEOUT => $this->timeOut,
            CURLOPT_TIMEOUT => $this->timeOut,
            CURLOPT_RETURNTRANSFER => true,
        );
        foreach($data as $k=>$v) {
            $options = CMap::mergeArray($_options, array(
                CURLOPT_URL => $v['url'],
                CURLOPT_POSTFIELDS => $v['requestData'],
            ));
            if (isset($v['curlOptions']) && is_array($v['curlOptions']) && !empty($v['curlOptions'])) {
                $options = CMap::mergeArray($options, $v['curlOptions']);
            }
            $conn[$k] = curl_init();
            curl_setopt_array($conn[$k], $options);
            //add the two handles
            curl_multi_add_handle($mh, $conn[$k]);
        }
        
        $active = null;
         //execute the handles
        do {
            $mrc = curl_multi_exec($mh, $active);
        } while ($mrc == CURLM_CALL_MULTI_PERFORM);

        while ($active && $mrc == CURLM_OK) {
            if (curl_multi_select($mh) != -1) {
                do {
                    $mrc = curl_multi_exec($mh, $active);
                } while ($mrc == CURLM_CALL_MULTI_PERFORM);
            }
        }
        
        $result = array();
        foreach($data as $k=>$v) {
            $result[$k] = array(
                'curlInfo' => curl_getinfo($conn[$k]),
                'response' => curl_multi_getcontent($conn[$k]),
            );
            //close the handles
            curl_multi_remove_handle($mh, $conn[$k]);
        }
        curl_multi_close($mh);
        $this->_logMultiResponse($result);
        return $result;
    }

3. Method#_handleMultiResponse()

private function _handleMultiResponse($result)
    {
        foreach($result as $k=>&$v) {
            $handleMethod = '_handle'. ucfirst($k);
            $v = $this->$handleMethod($v['response']);
        }
        
        return $result;
    }

从处理返回方法可以看到，我们仍然需要单独去处理每一个请求的返回，并返回！
