当我使用GCM时,出现如下错误:字段“数据”必须是JSON数组。任何人都有如何解决它的想法?谢谢。 有我的代码第一部分,省略部分代码:GCM返回错误:字段数据必须是json数组
<?php
$gcm_regid = array();
$gcm_data = array();
while ($row = mysql_fetch_array($result)) {
array_push($gcm_regid, $single_gcm_regid);
array_push($gcm_data , $notificationMessage);
}
?>
这里是第二部分:
<?php
$url = 'https://android.googleapis.com/gcm/send';
$apiKey = '******************************';
$registrationIDs = $gcm_regid;
$data = $gcm_data;
$fields = array('registration_ids' => $registrationIDs,
'data' => $data);
//http header
$headers = array('Authorization: key=' . $apiKey,
'Content-Type: application/json');
//curl connection
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
