如何从php从android推送通知

您好，我正在尝试从我的php web服务器向android mobile发送通知……但我得到的响应如下：

Unauthorized Error 401

下面是我的代码

<?php $url = 'https://android.googleapis.com/gcm/send';
$device_ids = array('devise ID' );
$headers = array('Authorization: key=api key',
'Content-Type: application/json');
$t_data = array();
$t_data['message'] = array('Someone commented on your business.');
$t_json = array( 'registration_ids' => $device_ids , 'data' => $t_data );

$ch = curl_init();

curl_setopt($ch, CURLOPT_HTTPHEADER,$headers );
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);
$result = curl_exec($ch);
if ($result === FALSE)
{
 die('Curl failed: ' . curl_error($ch));
}

curl_close($ch);

echo $result;
?>

如何解决此错误这是我在自己的GCM项目中实现的工作脚本。试着运行这个。 确保对“api_密钥”和“注册ID”进行更改

仔细检查

API密钥

。是的，我检查了它，但没有发现您定义了API密钥。。“授权：密钥=api密钥”。此api密钥在应用程序在Google上注册为GCM服务时发布。检查这个，也检查这个

 <?php
        $api_key = "AIzBpx4XbXkhkjwKd8P-v2d1Jk";
        $registrationIDs = array("APA91bjkj3Rjlo8T_URx15NqvxY2mRyQ");
        $message = "congratulations";
        $url = 'https://android.googleapis.com/gcm/send';
        $fields = array(
                    'registration_ids'  => $registrationIDs,
                    'data'              => array( "message" => $message ),
                    );

        $headers = array(
                        'Authorization: key=' . $api_key,
                        'Content-Type: application/json');

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt( $ch, CURLOPT_POST, true );
        curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
        curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
        $result = curl_exec($ch);
        curl_close($ch);

    echo $result;
    ?>
