PHPを使用して複数の端末にGCM通知を送信する

Question

GCM通知を複数の端末に送信する必要があります。ここで私はMySqlから登録IDの配列を取得するPHPコードを作って、複数のデバイスに通知を送信しようとしましたが、ここにいくつかの問題があります。

私のPHPコード：

<?php 
if($_SERVER['REQUEST_METHOD']=='GET'){ 

$tags = $_GET['tags']; 
$api_key = 'My OWN API KEY'; 

//Getting registration token we have to make it as array 

//Getting the message 
$message = Testing GCM'; 
$title= 'Cuboid'; 
$vibrate= '1'; 
$sound= '1'; 


require_once('dbConnect.php'); 

$user_ids = array(); 

     foreach ($_REQUEST['tags'] as $key => $val) { 
     $user_ids[$key] = filter_var($val, FILTER_SANITIZE_STRING); 
     } 
     $tagss = "'" . implode("','", $user_ids) . "'"; 
      $sql = "SELECT user_tags.user_id AS userID , gcm_token.regtoken AS regToken 
        FROM user_tags,gcm_token 
        WHERE tags IN ({$tagss}) AND user_tags.user_id=gcm_token.user_id"; 


$r = mysqli_query($con,$sql); 

//creating a blank array 
$result = array(); 
$reg_token = array(); 


//looping through all the records fetched 

    while ($row = mysqli_fetch_array($r)) { 
    $result['regToken'][] = $row['regToken']; 
     } 

    //Displaying the array in json format 

    echo json_encode(array('result'=>$result)); 

    $reg_token = (json_encode(array('result'=>$result))); 
    //$reg_token = array('result'=>$result); 


    $msg = array 
(
    'message' => $message, 
    'title'  => $title, 
    'subtitle' => 'Android Push Notification using GCM Demo', 
    'tickerText' => 'Ticker text here...Ticker text here...Ticker text here', 
    'vibrate' => $vibrate, 
    'sound'  => $sound, 
    'largeIcon' => 'large_icon', 
    'smallIcon' => 'small_icon' 
); 

//Creating a new array fileds and adding the msg array and registration token array here 
$fields = array 
(
    'registration_ids' => $reg_token, 
    'data'   => $msg 
); 

//Adding the api key in one more array header 
$headers = array 
(
    'Authorization: key=' . $api_key, 
    'Content-Type: application/json' 
); 

//Using curl to perform http request 
$ch = curl_init(); 
curl_setopt($ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send'); 
curl_setopt($ch,CURLOPT_POST, true); 
curl_setopt($ch,CURLOPT_HTTPHEADER, $headers); 
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false); 
curl_setopt($ch,CURLOPT_POSTFIELDS, json_encode($fields)); 

//Getting the result 
$results = curl_exec($ch); 
curl_close($ch); 

//Decoding json from results 
$res = json_decode($results); 

     mysqli_close($con); 
    }

JSON配列で結果を取得する必要があります。次のコードを試してください：

<?php 

if($_SERVER['REQUEST_METHOD']=='GET'){ 

$tags = $_GET['tags']; 
// Replace with the real server API key from Google APIs 
$apiKey = "YOUR_API_CODE"; 

$message = "Hello Raja"; 

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


require_once('dbConnect.php'); 

$user_ids = array(); 

     foreach ($_REQUEST['tags'] as $key => $val) { 
     $user_ids[$key] = filter_var($val, FILTER_SANITIZE_STRING); 
     } 
     $tagss = "'" . implode("','", $user_ids) . "'"; 
      $sql = "SELECT user_tags.user_id AS userID , gcm_token.regtoken AS regToken 
        FROM user_tags,gcm_token 
        WHERE tags IN ({$tagss}) AND user_tags.user_id=gcm_token.user_id"; 

$r = mysqli_query($con,$sql); 

$result = array(); 



//looping through all the records fetched 

    while ($row = mysqli_fetch_array($r)) { 
    $result[] = $row['regToken']; 
} 

//Displaying the array in json format 

    //echo json_encode(array('result'=>$result)); 

    echo json_encode(($result)); 

      $registrationIDs = ($result); 


    //echo json_encode(array('result'=>$result)); 


$fields = array(
    'registration_ids' => $registrationIDs, 
    'data' => array("message" => $message), 
); 
$headers = array(
    'Authorization: key=' . $apiKey, 
    '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); 
//curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); 

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($fields)); 

// Execute post 
$result = curl_exec($ch); 

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

    ?>

更新：

プッシュ通知を送信するためのAPIエンドポイントがhttps://fcm.googleapis.com/fcm/send

に https://android.googleapis.com/gcm/send から変更されupdated documentation 1として古いエンドポイントがありますまだ動作していますが、最新のものを使用することをお勧めします。 このコードは、両方のエンドポイントで同じです。

が通知を送信するように関数を宣言し、これを試してみてください：

function sendfcmMessage($registrationIds, $msg) 
{ 

    if (!defined('API_ACCESS_KEY')) define('API_ACCESS_KEY', '<PUT_YOUR_KEY_HERE>'); 
    $fields = array('registration_ids' => $registrationIds, 'data' => $msg, 'content-available' => 1, 'priority' => 'high'); //set priority as required 
    $headers = array('Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json'); 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, 'https://android.googleapis.com/gcm/send'); 
    curl_setopt($ch, CURLOPT_POST, true); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); 
    $result = curl_exec($ch); 
    curl_close($ch); 
    return $result; 
} 

このような使用も、

$msg = array('message' => $message, 
      'title' => $title, 
      'body' => $body, 
      'subtitle' => $subtitle, 
      'tickerText' => $ticker_text, 
      'vibrate' => $vibrate, 
      'sound' => $sound, 
      'largeIcon' => 'large_icon', 
      'smallIcon' => 'small_icon'); 

    $registrationIds = array(); 

    while ($row = mysqli_fetch_array($r)) { 
     array_push($registrationIdsIOS, $row['regToken'];); 
    } 

    sendfcmMessage($registrationIds, $msg); 

をあなたはまた、この関数の結果を印刷してデバッグすることができます通知が送信されたかどうかを確認し、通知が送信されなかった理由を知ることもできます。

echo sendfcmMessage($registrationIds, $msg);
