嗨，我正在尝试通过 php curl 获取 Goto 会议 OAuth 访问令牌。但是当我打电话时它什么也不返回。请指导我如何获得它，代码如下。

$api_key = "123456"; $redirect_url = urlencode("URL");

$webinar_url = "https://api.citrixonline.com/oauth/authorize?client_id=".$api_key."&redirect_uri=".$redirect_url;

function getWebinarData($link) { $headers = array("HTTP/1.1", "Content-type: application/json", "Accept: application/json"); 

$curl = curl_init($link);

curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);      //2

$response = curl_exec($curl);
echo "<pre>DATA: ";print_r($response);echo "</pre>";
curl_close($curl);

return $response;

}
