我从新的谷歌通知服务Firebase Cloud Messaging开始。
多亏了这段代码https://github.com/firebase/quickstart-android/tree/master/messaging，我才能从我的Firebase用户控制台发送通知到我的Android设备。
有没有什么API或方法可以在不使用Firebase控制台的情况下发送通知?我的意思是，例如，一个PHP API或类似的东西，直接从我自己的服务器创建通知。

下面是我使用CURL的项目中的工作代码。
<?PHP
//Avoid keys confusions!
//firebase Cloud Messaging have 3 different keys:
//API_KEY, SERVER_KEY and PUSH_KEY ... here we need SERVER_KEY
// SERVER access key from Google firebase Console
define( 'SERVER_ACCESS_KEY', 'YOUR-SERVER-ACCESS-KEY-GOES-HERE' );
$registrationIds = array( $_GET['id'] );
// prep the bundle
$msg = array
(
'message' => 'here is a message. message',
'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
(
// use this to method if want to send to topics
// 'to' => 'topics/all'
'registration_ids' => $registrationIds,
'notification' => $msg
);
$headers = array
(
'Authorization: key=' . SERVER_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/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;

简介
我编译了上面的大部分答案，并根据FCM HTTP连接文档更新了变量，以制定一个在2021年适用于FCM的解决方案。感谢Hamzah Malik给出的非常有见地的回答。
先决条件
首先，确保你已经将你的项目与Firebase连接起来，并且你已经在你的应用程序上设置了所有的依赖项。如果你还没有，首先去看FCM配置文档
如果这样做了，您还需要从API复制项目的服务器响应键。转到Firebase控制台，单击正在进行的项目，然后导航到;
Project Settings(Setting wheel on upper left corner) -> Cloud Messaging Tab -> Copy the Server key
配置PHP后端
我用Ankit Adlakha的API调用结构和FCM文档编译了Hamzah的答案，得出了下面的PHP函数:
function sendGCM() {
// FCM API Url
$url = 'https://fcm.googleapis.com/fcm/send';
// Put your Server Response Key here
$apiKey = "YOUR SERVER RESPONSE KEY HERE";
// Compile headers in one variable
$headers = array (
'Authorization:key=' . $apiKey,
'Content-Type:application/json'
);
// Add notification content to a variable for easy reference
$notifData = [
'title' => "Test Title",
'body' => "Test notification body",
'click_action' => "android.intent.action.MAIN"
];
// Create the api body
$apiBody = [
'notification' => $notifData,
'data' => $notifData,
"time_to_live" => "600" // Optional
'to' => '/topics/mytargettopic' // Replace 'mytargettopic' with your intended notification audience
];
// Initialize curl with the prepared headers and body
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url );
curl_setopt ($ch, CURLOPT_POST, true );
curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt ($ch, CURLOPT_POSTFIELDS, json_encode($apiBody));
// Execute call and save result
$result = curl_exec ( $ch );
// Close curl after call
curl_close ( $ch );
return $result;
}
自定义通知推送
要通过令牌提交通知，使用' To ' => '注册令牌'
会发生什么
我在我的网站后台设置了这个功能，并在Postman上进行了测试。如果您的配置是成功的，您应该期望一个类似于下面的响应;
{"message":"{"message_id":3061657653031348530}"}
使用curl的示例
向特定设备发送消息
要将消息发送到特定设备，请将该设置为特定应用实例的注册令牌
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send
向主题发送消息
这里的主题是:/topics/foo-bar
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{ "to": "/topics/foo-bar","data": { "message": "This is a Firebase Cloud Messaging Topic Message!"}}' https://fcm.googleapis.com/fcm/send
向设备组发送消息
向设备组发送消息与向单个设备发送消息非常相似。将to参数设置为设备组的唯一通知键
curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>" -X POST -d '{"to": "<aUniqueKey>","data": {"hello": "This is a Firebase Cloud Messaging Device Group Message!"}}' https://fcm.googleapis.com/fcm/send
使用服务API的示例
火网址:https://fcm.googleapis.com/fcm/send
头
Content-type: application/json
Authorization:key=<Your Api key>
请求方式:POST
请求体
发送到特定设备的消息
{
"data": {
"score": "5x1",
"time": "15:10"
},
"to": "<registration token>"
}
主题的消息
{
"to": "/topics/foo-bar",
"data": {
"message": "This is a Firebase Cloud Messaging Topic Message!"
}
}
给设备组的消息
{
"to": "<aUniqueKey>",
"data": {
"hello": "This is a Firebase Cloud Messaging Device Group Message!"
}
}
下面是我使用CURL的项目中的工作代码。
<?PHP
//Avoid keys confusions!

'registration_ids' => $registrationIds,

);
$headers = array
(
'Authorization: key=' . SERVER_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/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;
使用Firebase Console可以根据应用程序包向所有用户发送消息。但对于CURL或PHP API，这是不可能的。
通过API可以向指定的设备ID或订阅的用户发送通知给选定的主题或订阅的主题用户。
