我正在尝试向Android手机发送消息,但不断收到带有文本的响应代码401：未经授权.此外,我一直在阅读关于使用什么密钥的不同故事,我知道3个密钥：项目ID(编号),服务器应用程序密钥和浏览器应用程序密钥.所以我尝试了所有3个,都具有相同的结果.

我的代码：

$headers = array("Content-Type" => "application/json", "Authorization" => "key=" . "mykey");

$data = array(

'data' => $messageText,

'registration_ids' => array($deviceRegistrationId)

);

$ch = curl_init();

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");

curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);

curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));

error_log(json_encode($data));

$response = curl_exec($ch);

curl_close($ch);

error_log($response);
