PHP中的Curl Post返回null

我有一个可以通过控制台成功执行的curl post：

curl-i-H'Accept:application/vnd.twitchtv.v3+json'-H'客户端ID:XXX''https://api.twitch.tv/kraken/channels/EisohneWaffel“

返回一个json文件

现在我试图通过php发布相同的内容，它返回

NULL

：：

   /* Init result array */
    $result = array();

    /* curl options */
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, 'https://api.twitch.tv/kraken/channels/EisohneWaffel');
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Accept: application/vnd.twitchtv.v3+json',
        'Client-ID: '.Constants::TWITCH_API_CLIENT
    ));
    $result['data'] = curl_exec($ch);
    $result['info'] = curl_getinfo($ch);
    curl_close($ch);

    /* return result array */
    var_dump($result);

$result['data']

为空，

$result['info']

有一些信息：

"info" => array:26 [▼
    "url" => "https://api.twitch.tv/kraken/channels/EisohneWaffel"
    "content_type" => null
    "http_code" => 0

你知道我哪里错了吗？

试试这个，curl\u exe在成功时返回TRUE，失败时返回FALSE

    $header_size = curl_getinfo($ch,CURLINFO_HEADER_SIZE);
    $result['header'] = substr($response, 0, $header_size);
    $result['body'] = substr( $response, $header_size );
    $result['http_code'] = curl_getinfo($ch,CURLINFO_HTTP_CODE);
    $result['last_url'] = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL);
