我在使用curl调取接口获得数据时，出现了curl_errno()返回错误码 '6' 的情况，百度了一下

<code>CURLE_COULDNT_RESOLVE_HOST (6)
Couldn't resolve host. The given remote host was not resolved.</code>

原来程序是可以正常获取接口返回数据的，这个情况是突然出现的，不知道是不是api限制了调用？目前还不知道具体解决办法，大家如果有遇到相同情况，可以分享一下解决办法，谢谢。
PS:直接在浏览器访问接口url是可以获取得到数据的。
curl代码：

<code>public function getApiDataWithCurl($params = array()){
        $doc = array(
            'result'=>0,
            'content'=>'',
        );
        if(!isset($params['feed_id'])) return $doc;
        if(!isset($params['apikey'])) return $doc;
        $getUrl = $this->apiUrl.'?';
        foreach($params as $k => $v){
            if($v != ''){
                $getUrl .=$k.'='.$v.'&';
            }
        }
        $getUrl = substr($getUrl,0,strlen($getUrl)-1);

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$getUrl);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HEADER, false);
        $response_content = curl_exec($ch);
        $error_code = curl_errno($ch);
        $curl_info = curl_getinfo($ch);
        curl_close($ch);
        $response_content = simplexml_load_string($response_content);
        $json = json_encode($response_content);
        $response_content = json_decode($json,TRUE);
        if($error_code || (!$response_content && $curl_info['http_code']!=200)){
            return 'CURL ERROR: error code '.$error_code;
        }else{
            $doc = array(
                'result'=>1,
                'content'=>$response_content,
            );
            return $doc;
        }
    }</code>

这是无法解析域名的问题，你试下把url打出来，看看能否ping通
