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。

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);

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;

这个链接的解决方案对我帮助很大。你可以去看看。

带有这些指令行的curl.php文件可以工作。

<?php 
// Server key from Firebase Console define( 'API_ACCESS_KEY', 'AAAA----FE6F' );
$data = array("to" => "cNf2---6Vs9", "notification" => array( "title" => "Shareurcodes.com", "body" => "A Code Sharing Blog!","icon" => "icon.png", "click_action" => "http://shareurcodes.com"));
$data_string = json_encode($data);
echo "The Json Data : ".$data_string;
$headers = array ( 'Authorization: key=' . API_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_POSTFIELDS, $data_string);
$result = curl_exec($ch);
curl_close ($ch);
echo "<p>&nbsp;</p>";
echo "The Result : ".$result;

请记住,您需要使用另一个浏览器执行curl.php文件,而不是从用于获取用户令牌的浏览器执行。只有在浏览其他网站时才能看到通知。

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。

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;
    }

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。
