Google云消息传递 - 使用PHP向Android发送推消息

我正在使用GCM推送消息的Android项目。我想只使用PHP而不是HTML发送通知。我如何实现这一目标？我试过的方法是把gcm_regid和消息作为参数放到$ gcm-> send_notification（$ registration_ids，$ msg），但是我总是收到一个错误消息： - 字段“data”必须是JSON数组：[“You Have A Notification！“]Google云消息传递 - 使用PHP向Android发送推消息

”你有通知！“是我的味精！请帮忙！！谢谢！

代码send_notification是

public function send_notification($registatoin_ids, $message) { 

    include_once './config.php'; 

    // Set POST variables 
    $url = 'https://android.googleapis.com/gcm/send'; 

    $fields = array(
     'registration_ids' => $registatoin_ids, 
     'data' => $message, 
    ); 

    $headers = array(
     'Authorization: key=' . GOOGLE_API_KEY, 
     'Content-Type: application/json' 
    ); 
    // Open connection 
    $ch = curl_init(); 

    // Set the url, number of POST vars, POST data 
    curl_setopt($ch, CURLOPT_URL, $url); 

    curl_setopt($ch, CURLOPT_POST, true); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 

    // Disabling SSL Certificate support temporarly 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 

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

    // Execute post 
    $result = curl_exec($ch); 
    if ($result === FALSE) { 
     die('Curl failed: ' . curl_error($ch)); 
    } 

    // Close connection 
    curl_close($ch); 
    echo $result; 
} 

}

这是用于使用上点击按钮的发送消息的index.php文件。然而，我需要在后台自动执行此操作，而无需按任何按钮，并且希望在PHP中实现它。

具有u使用下面我给出的答案发送成功通知M还面临着同样的问题 – user3233280

@ user3233280是的！这是很久以前，所以不记得位置，但我认为GCM PHP在发送消息函数中有一个参数，叫做price，需要将其更改为我在android接收函数中设置的变量名称。希望我清楚！ – 4kshay

也许这将工作：

$fields = array(
    'registration_ids' => $registatoin_ids, 
    'data' => array("message" => $message), 
);

似乎是解决方案，但它不发送消息。它发送一条空白消息而不是指定的消息。我会尽力弄清楚这一点！谢谢：） – 4kshay

您将需要太嵌入registration_id数组。

$fields = array(
    'registration_ids' => array($registatoin_ids), 
    'data' => array("message" => $message), 
);

$fields[] = array(
      'registration_ids' =>$registatoin_ids, 
      'data' =>$message 
     );

使用方括号与$领域，这将使它成为一个JSON数组
