当我试图通过下面的php发送gcm消息时，我得到了这个错误：
｛"multicast_id"：898574426215974401，"成功"：0，"失败"：1，"规范_ids"：0、"结果"：[｛"错误"："无效注册"｝]｝
然而，服务器API密钥正是Google提供给我使用的，gcm_token正准确地存储到我的数据库中。我不知道问题出在哪里。
这是我的服务器端php:
<?php
require 'db_connect.php';
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'AIzaSyREST OF MY KEY' );
//insert the message into a database
$sql = "SELECT gcm_token FROM users WHERE user_id='1' LIMIT 1;";
// preform
if (!mysqli_query($Thesisdb, $sql)) {
printf("Errormessage: ", mysqli_error($Thesisdb));
mysqli_close($Thesisdb);
} else{
$results = mysqli_query($Thesisdb, $sql);
$registrationIds = array($results);
// prep the bundle
$msg = array
(
'message' => '$user',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',
'vibrate' => 1,
'sound' => 1,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);
$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 );
echo $result;
}
?>
mysqli_query返回Boolen值（true或false），因此这不会直接起作用。
我们必须使用fetch array、fetch assoc.将mysqli_query返回值转换为数组
$results = mysqli_query($Thesisdb, $sql);
$registrationIds = array($results);
组合所有GCM代币的代码
registrationIds=array();
$sql="SELECT `user_id`,`push_notification_registration_id` FROM `tbl1` WHERE `user_status`='Active' AND `push_notification_registration_id`!=''";
$fire=mysqli_query($this->conn,$sql);
$users=array();
if( (isset($fire))&&(!empty($fire)) ){
while($result=mysqli_fetch_assoc($fire)){
array_push($users,$result);
}
}
foreach($users as $single_user){
$register_id=$single_user['push_notification_registration_id'];
array_push($registrationIds,$register_id);
}
$msg = array
(
'title' => $news_title,
'subtitle' => $news_description,
'tickerText' => 'Ticker Text',
'vibrate' => 1,
'sound' => 1,
'news_id' => $news_id,
'notification_type' => 'news'
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . YOUR_GOOGLE_API_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 );
