我编写了一些php代码,我能够使用regd向设备发送通知。
我还设法创建了一组regd,成功地接收了谷歌文档中描述的notification_key。
但是我不能向组发送通知。我试图使用相同的方法来发送通知,但不是使用regd,而是使用我在创建组时从GCM收到的notification_key,但这种方法不起作用,它给了我未注册的错误。如果我尝试注册相同的notification_key_name GCM说它已经注册。
我不确定我是否必须通过另一种方法发送它,或者我是否做错了什么。
-
当我使用regd发送通知时,我收到此消息从GCM:
{"multicast_id":517年…442年,"成功":2,"失败":0,"canonical_ids":0,"结果":[{"message_id":"0:140…ecd"},{"message_id":"0:140…ecd"}]}
-
当我创建组时,我从GCM收到以下消息:
{"notification_key":"APA91…nz9Q"}
-
当我尝试使用上面消息上收到的notification_key向组发送消息时,我从GCM收到此消息:
{"multicast_id":80年…63年,"成功":0,"失败":1、"canonical_ids":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:
{"error":"notification_key already exists"}
下面是我使用的代码。
<?php
class GCM {
const GOOGLE_API_KEY= " *** MY API KEY ***"; // Place your Google API Key
const PROJECT_KEY= " *** MY PROJECT KEY ***";
function __construct() {
}
/**

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(

'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) {

我在尝试发送带有通知键的gcm时遇到了类似的问题。文档中有一个问题。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
你可以在我的博客文章中看到更多:https://medium.com/appunite-edu-collection/d7df385b0ff4
我遵循了来自Google文档的文档(我正在推动iOS和Android)。
{
"to": "your_token_ID",
"data": {
"hello": "This is a Firebase Cloud Messaging Device Group Message!",
}
}
但它不工作,所以我尝试:
{
"to": "your_token_ID",
"notification": {
"sound": "default",
"gcmSandbox": "true",
"badge": 1,
"title" : "Push Title",
"body": "Push Body"
}
}
这个方法对我来说很有效,希望能对别人有所帮助。
