プッシュ通知を作成しようとしているサーバー側のコードがいくつかあります。結果は次のようになります。
{"multicast_id":8714083978034301091,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1350807053347963%9aab4bd8f9fd7ecd"}]}
プッシュ通知の送信に使用した PHP コードを次に示します。ところで、プッシュは起こらなかったので、理由を理解しようとしています:
$url = 'https://android.googleapis.com/gcm/send';
$device_ids = array( $device_id );
$t_data = array();
$t_data['message'] = 'Someone commented on your business.';
$t_json = array( 'registration_ids' => $device_ids , 'data' => $t_data );
// Open connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Authorization: key=my_key', 'Content-Type: application/json' ) );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $t_json ) );
curl_setopt($ch, CURLOPT_URL, $url);
// Execute post
$result = curl_exec($ch);
if ($result === FALSE)
{
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);

しかし、何を試してもプッシュ通知が物理デバイスに表示されません。デバイスに表示させる方法はありますか?
