curl - PHP 脚本可以在 Mac 上运行，但不能在 Windows 上运行

Question

我正在利用 parse.com，与框架交互的 PHP 库仅在使用 MAMP 的 mac 上工作，但在使用 XAMPP 或 WAMP 的 Windows 上，每次都会因相同的原因失败。下面是每次建立连接时调用的函数进行解析。在 Windows 上运行时，$responseCode = 0 并且 $response 为 false。当我在 Mac 上运行它时， $responseCode = 200 并且 $response 也返回它所假设的 json 数据。到底是怎么回事？为什么不同的平台会导致失败？

public function request($args){
        $isFile = false;
        $c = curl_init();
        curl_setopt($c, CURLOPT_TIMEOUT, 30);
        curl_setopt($c, CURLOPT_USERAGENT, 'parse.com-php-library/2.0');
        curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($c, CURLINFO_HEADER_OUT, true);
        if(substr($args['requestUrl'],0,5) == 'files'){
            curl_setopt($c, CURLOPT_HTTPHEADER, array(
                'Content-Type: '.$args['contentType'],
                'X-Parse-Application-Id: '.$this->_appid,
                'X-Parse-Master-Key: '.$this->_masterkey
            ));
            $isFile = true;
        }
        else if(substr($args['requestUrl'],0,5) == 'users' && isset($args['sessionToken'])){
            curl_setopt($c, CURLOPT_HTTPHEADER, array(

        $expectedCode = '200';
        if($args['method'] == 'POST' && substr($args['requestUrl'],0,4) != 'push'){
            $expectedCode = '201';
        }

        if($expectedCode != $responseCode){
            //BELOW HELPS WITH DEBUGGING
                    //echo "VAR DUMP:";
                    //var_dump($response);      
        }

        return $this->checkResponse($response,$responseCode,$expectedCode);
    }

private function checkResponse($response,$responseCode,$expectedCode){
        //TODO: Need to also check for response for a correct result from parse.com
        if($responseCode != $expectedCode) {

            $error = json_decode($response);

替换:

$response = curl_exec($c);

与:

if( ! $response = curl_exec($c) ) {
    die(curl_error($c));
}

或者替换您喜欢的任何错误处理代码。
