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!"
  }
}

首先，你需要从android获得一个令牌，然后你可以调用这个php代码，你甚至可以在你的应用程序中为进一步的操作发送数据。

 <?php

// Call .php?Action=M&t=title&m=message&r=token
$action=$_GET["Action"];


switch ($action) {
    Case "M":
         $r=$_GET["r"];
        $t=$_GET["t"];
        $m=$_GET["m"];

        $j=json_decode(notify($r, $t, $m));

        $succ=0;
        $fail=0;

        $succ=$j->{'success'};
        $fail=$j->{'failure'};

        print "Success: " . $succ . "<br>";
        print "Fail   : " . $fail . "<br>";

        break;


default:
        print json_encode ("Error: Function not defined ->" . $action);
}

function notify ($r, $t, $m)
    {
    // API access key from Google API's Console
        if (!defined('API_ACCESS_KEY')) define( 'API_ACCESS_KEY', 'Insert here' );
        $tokenarray = array($r);
        // prep the bundle
        $msg = array
        (
            'title'     => $t,
            'message'     => $m,
           'MyKey1'       => 'MyData1',
            'MyKey2'       => 'MyData2', 

        );
        $fields = array
        (
            'registration_ids'     => $tokenarray,
            'data'            => $msg
        );

        $headers = array
        (
            'Authorization: key=' . API_ACCESS_KEY,
            'Content-Type: application/json'
        );

        $ch = curl_init();
        curl_setopt( $ch,CURLOPT_URL, '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 );
        return $result;
    }


?>

如果您正在使用PHP，我建议使用用于Firebase的PHP SDK: Firebase Admin SDK。为了一个简单的配置，您可以按照以下步骤:

从Firebase获取项目凭证json文件(初始化sdk)，并将其包含在项目中。

在项目中安装SDK。我使用composer:

composer require kreait/firebase-php ^4.35

试试SDK文档中云消息会话的任何例子:

use Kreait\Firebase;
use Kreait\Firebase\Messaging\CloudMessage;

$messaging = (new Firebase\Factory())
->withServiceAccount('/path/to/firebase_credentials.json')
->createMessaging();

$message = CloudMessage::withTarget(/* see sections below */)
    ->withNotification(Notification::create('Title', 'Body'))
    ->withData(['key' => 'value']);

$messaging->send($message);

Firebase云消息传递有一个服务器端api，您可以调用它来发送消息。见https://firebase.google.com/docs/cloud-messaging/server。

发送消息可以像使用curl调用HTTP端点一样简单。看到https://firebase.google.com/docs/cloud-messaging/server implementing-http-connection-server-protocol

curl -X POST --header "Authorization: key=<API_ACCESS_KEY>" \
    --Header "Content-Type: application/json" \
    https://fcm.googleapis.com/fcm/send \
    -d "{\"to\":\"<YOUR_DEVICE_ID_TOKEN>\",\"notification\":{\"title\":\"Hello\",\"body\":\"Yellow\"}}"

您可以在任何环境中使用所有这些REST API，但是这里列出的许多平台都有专门的所谓管理sdk。

如果你想从android发送推送通知，请查看我的博客文章

发送推送通知从一个android手机到另一个没有服务器。

发送推送通知只不过是发送到https://fcm.googleapis.com/fcm/send的请求

使用volley的代码片段:

    JSONObject json = new JSONObject();
 try {
 JSONObject userData=new JSONObject();
 userData.put("title","your title");
 userData.put("body","your body");

json.put("data",userData);
json.put("to", receiverFirebaseToken);
 }
 catch (JSONException e) {
 e.printStackTrace();
 }

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest("https://fcm.googleapis.com/fcm/send", json, new Response.Listener<JSONObject>() {
 @Override
 public void onResponse(JSONObject response) {

Log.i("onResponse", "" + response.toString());
 }
 }, new Response.ErrorListener() {
 @Override
 public void onErrorResponse(VolleyError error) {

}
 }) {
 @Override
 public Map<String, String> getHeaders() throws AuthFailureError {

Map<String, String> params = new HashMap<String, String>();
 params.put("Authorizationey=" + SERVER_API_KEY);
 params.put("Content-Typepplication/json");
 return params;
 }
 };
 MySingleton.getInstance(context).addToRequestQueue(jsonObjectRequest);

我建议你们都去看看我的博客以获得完整的细节。

或者你可以使用Firebase的云功能，对我来说，这是实现推送通知的更简单的方法。 重火力点/ functions-samples
