我制作了一些PHP代码,并且能够使用regId向设备发送通知。
我还成功创建了一组regId,成功接收了google documentation中描述的notification_key。
但我无法向群组发送通知。我尝试使用相同的方法发送通知但不是使用regId我使用的是我在创建组时从GCM收到的notification_key,但这种方法不起作用,它给了我NotRegistered错误。 如果我尝试使用相同的notification_key_name注册GCM,则说它已经注册。
我不确定是否必须通过其他方法发送或者我做错了。
当我使用regId发送通知时,我收到此消息 来自GCM:
{" multicast_id":517 ... 442"成功":2"失效":0," canonical_ids&#34 ;: 0,"结果":[{" MESSAGE_ID":" 0:140 ... ECD"},{" MESSAGE_ID":&# 34; 0:140 ... ECD"}]}
当我创建组时,我从GCM收到此消息:
{" notification_key":" APA91 .... nz9Q"}
当我尝试使用上面收到的消息收到的notification_key将消息发送到组时,我收到了来自GCM的消息:
{" multicast_id":80 ... 63,"成功":0,"失效":1," canonical_ids&#34 ;: 0,"结果":[{"错误":" NotRegistered"}]}
当我尝试使用相同的notification_key_name再次创建组时,我从GCM收到此消息:
{"错误":" notification_key已经存在"}
以下是我正在使用的代码。
<?php
class GCM {
const GOOGLE_API_KEY= " *** MY API KEY ***"; // Place your Google API Key
const PROJECT_KEY= " *** MY PROJECT KEY ***";
function __construct() {
}
/**
* Sending Push Notification
*/
public function send_notification($registatoin_ids, $message) {
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message
);
$headers = array(
'Authorization: key=' . self::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));
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
public function requestNotificationKeyFromGCM($registatoin_ids, $username) {
//Google cloud messaging GCM-API url
$url = 'https://android.googleapis.com/gcm/notification';
$request = array(
'operation' => 'create',
'notification_key_name' => $username,
'registration_ids' => $registatoin_ids,
);
$headers = array(
'Authorization: key=' . self::GOOGLE_API_KEY,
'project_id: ' . self::PROJECT_KEY,
'content-type: application/json'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($request));
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
curl_close($ch);
echo $result;

我在尝试使用通知密钥发送gcm时出现类似问题。文档中存在问题。 而不是使用:
curl -vvv -X POST --header "Content-Type: application/json" --header "project_id: <YOUR-PROJECT-ID>" --header "Authorization: key=<YOUR-PROJECT-SECRET-KEY>" --data @- "https://android.googleapis.com/gcm/send" << EOF
{
"registration_ids": ["<REGISTRATION-ID-FROM-DEVICE>"],
"data": {},
}
EOF
你必须使用:
curl -vvv -X POST --header "Content-Type: application/json" --header "project_id: <YOUR-PROJECT-ID>" --header "Authorization: key=<YOUR-PROJECT-SECRET-KEY>" --data @- "https://android.googleapis.com/gcm/send" << EOF
{
"to": "<NOTIFICATION-ID>",
"data": {},
}
EOF

我按照Google's Documentation的文档进行操作 (我推动iOS和Android)。
{
"to": "your_token_ID",
"data": {
"hello": "This is a Firebase Cloud Messaging Device Group Message!",
}
}
但它没有用,所以我尝试了:
{
"to": "your_token_ID",
"notification": {
"sound": "default",
"gcmSandbox": "true",
"badge": 1,
"title" : "Push Title",
"body": "Push Body"
}
}
这种方法对我有用,希望它能帮到别人。
