將MySQL結果集轉換爲JSON數組以消耗Google GCM API的問題

我正在開發一個應用程序，我將不得不集成GCM功能。收件人的device_id存儲在MySQL數據庫中，然後通過CURL將其檢索併發送到Google GCM API網址。問題是，當我這樣做，我收到一條錯誤：將MySQL結果集轉換爲JSON數組以消耗Google GCM API的問題

Recipients_Id field is not a JSON Array.

PHP代碼爲：

 //get the recipients gcm_ids 
    if (isset($_POST["deviceid"]) && isset($_POST["message"]) && isset($_POST["recipient_id"])) { 
     require_once __DIR__ . '/db_connect.php'; 
include_once './GCM.php'; 
$gcm = new GCM(); 
// connecting to db 
$db = new DB_CONNECT(); 
$device_id=$_POST['deviceid']; 
$recipient_id=$_POST['recipient_id']; 
$get_details=mysql_query("select id,name from gcm_users where gcm_regid='$device_id' "); 
$row_details=mysql_fetch_array($get_details); 
$user_name=$row_details["name"]; 
$user_id=$row_details["id"]; 
$recipients_gcm_ids=mysql_query("SELECT gcm_regid from gcm_users where id='$recipient_id'"); 
$rec_gcm1=array(); 
while($row = mysql_fetch_assoc($recipients_gcm_ids)) 
{array_push($rec_gcm1,$row);} 
$recipients_gcm=array(); 
$recipients_gcm=json_encode($rec_gcm1); 
$message = array("price" => $message1); 
$result = $gcm->send_notification($recipients_gcm, $message); 


//The class that sends the message to the Google API url 
     class GCM { 

//put your code here 
// constructor 
function __construct() { 

} 

/** 
* Sending Push Notification 
*/ 
public function send_notification($Recipients_Id, $message) { 
    // include config 
    include_once './config.php'; 

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

    $fields = array(
     'Recipients_Id' => $Recipients_Id, 
     '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($ch); 
    echo "Result Is:".$result; 
}

據我所知，這個問題涉及這行代碼：

$result = $gcm->send_notification($recipients_gcm, $message);

但是，我不知道任何方法（但），我會用它來創建一個PHP的JSON數組，除了使用「json_encode」功能。也許是有另一種方式來規避：

 "Not a JSON Array" error ?

順便說的print_r（$ recipients_gcm）的輸出是：

[{"gcm_regid": "ABCDEFGH12y63i4455u65y4i4p4yu4t3i3zzttyuuiioo"}]

我看到一對夫婦的問題代碼：

您正在向您的send_notification函數發送一個reg ids的json字符串。相反，你應該發送一個註冊ID數組。嘗試取出這兩條線，並使用數組$rec_gcm1來代替。

$recipients_gcm=array(); 
$recipients_gcm=json_encode($rec_gcm1);

調用此相反：

$result = $gcm->send_notification($rec_gcm1, $message);

接下來，在send_notification功能，改變$fields這樣：

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

即改變你Recipients_Id關鍵registration_ids否則谷歌GCM服務器韓元」不能解析它。
