錯誤與PHP

Question

GCM推送通知。當我使用GCM推送通知，

Field"data"mustbeaJSONarray: { 
    "details": [ 
     { 
      "regid": "APA91bH8zxTxfoSLWhE21IbTR9a10cvIcm17-zsPY_0OAy3JhO_8gTwMwwAUd_4vZiLu5UF4A1m8R3TEIffDaChVR0y2us9iebngkaWlOM34ix4PUeOgIoM9aGOcxLLECAGjKNSwupTY0p2O0BeXjSCp8RYFaD-xzg", 
      "status": "true", 
      "post_userid": "34", 
      "post_id": "7", 
      "postuser_name": "dev", 
      "message": "gggggg" 
     }]} 

而且給我的錯誤：「字段的數據必須是一個JSON陣列」

請指導我

我的代碼：

$fields = array('data'=> $message); 
$headers = array('Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json'); 
$ch = curl_init(); 
curl_setopt($ch,CURLOPT_URL, '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); 
echo $result;

嗯，你的JSON確實不是n像它應該看起來一樣。 它應該是這樣的：

{ 
    "data": { 
     "status": "true", 
     "post_userid": "34", 
     "post_id": "7", 
     "postuser_name": "dev", 
     "message": "gggggg" 
    }, 
    "registration_ids":["APA91bH8zxTxfoSLWhE21IbTR9a10cvIcm17-zsPY_0OAy3JhO_8gTwMwwAUd_4vZiLu5UF4A1m8R3TEIffDaChVR0y2us9iebngkaWlOM34ix4PUeOgIoM9aGOcxLLECAGjKNSwupTY0p2O0BeXjSCp8RYFaD-xzg"] 
}
