如何在不使用Firebase控制台的情况下发送Firebase Cloud 消息通知？ [关闭]-Java 学习之路

168

我开始使用新的Google服务进行通知， Firebase Cloud Messaging .

感谢此代码https://github.com/firebase/quickstart-android/tree/master/messaging我能够将 Firebase User Console 的通知发送到我的Android设备 .

是否有任何API或方式可以在不使用Firebase控制台的情况下发送通知？我的意思是，例如，PHP API或类似的东西，直接从我自己的服务器创建通知 .

您可以使用例如用于Google Cloud Messaging（GCM）的PHP脚本 . Firebase及其控制台就在GCM之上 .

我在github上发现了这个：https://gist.github.com/prime31/5675017

提示：此PHP脚本生成android notification .

因此：如果您想在Android中接收并显示通知，请阅读this answer from Koot .

可以使用FCM HTTP v1 API endpoints 将通知或数据消息发送到firebase基础 Cloud 消息服务器 . https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send .

您需要使用Firebase控制台生成和下载服务帐户的私钥，并使用google api客户端库生成访问密钥 . 使用任何http库将消息发布到上述终点，下面的代码显示使用OkHTTP发布消息 . 您可以在firebase cloud messaging and sending messages to multiple clients using fcm topic example找到完整的服务器端和客户端代码

如果需要发送特定客户端消息，则需要获取客户端的firebase注册密钥，请参阅sending client or device specific messages to FCM server example

String SCOPE = "https://www.googleapis.com/auth/firebase.messaging";
String FCM_ENDPOINT
     = "https://fcm.googleapis.com/v1/projects/zoftino-stores/messages:send";

GoogleCredential googleCredential = GoogleCredential
    .fromStream(new FileInputStream("firebase-private-key.json"))
    .createScoped(Arrays.asList(SCOPE));
googleCredential.refreshToken();
String token = googleCredential.getAccessToken();



final MediaType mediaType = MediaType.parse("application/json");

OkHttpClient httpClient = new OkHttpClient();

Request request = new Request.Builder()
    .url(FCM_ENDPOINT)
    .addHeader("Content-Type", "application/json; UTF-8")
    .addHeader("Authorization", "Bearer " + token)
    .post(RequestBody.create(mediaType, jsonMessage))
    .build();


Response response = httpClient.newCall(request).execute();
if (response.isSuccessful()) {
    log.info("Message sent to FCM server");
}

Firebase Cloud Messaging具有服务器端API，您可以调用它们来发送消息 . 见https://firebase.google.com/docs/cloud-messaging/server .

发送消息可以像使用 curl 来调用HTTP endpoints 一样简单 . 见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\":{\"body\":\"Yellow\"},\"priority\":10}"
```

使用卷曲的例子

Send messages to specific devices

要将消息发送到特定设备，请将其设置为特定应用程序实例的注册令牌

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

Send messages to topics

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

Send messages to device groups

将消息发送到设备组与将消息发送到单个设备非常相似 . 将to参数设置为设备组的唯一通知密钥

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Service API的示例

API网址： https://fcm.googleapis.com/fcm/send

头

Content-type: application/json
Authorization:key=<Your Api key>

申请方法： POST

Request Body

给特定设备的消息

{
  "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to": "<registration token>"
}

消息到主题

{
  "to": "/topics/foo-bar",
  "data": {
    "message": "This is a Firebase Cloud Messaging Topic Message!"
  }
}

消息到设备组

{
  "to": "<aUniqueKey>",
  "data": {
    "hello": "This is a Firebase Cloud Messaging Device Group Message!"
  }
}

首先，您需要从Android获取令牌然后您可以调用此PHP代码，您甚至可以发送数据以在您的应用程序中进一步操作 .

<?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Frank所述，您可以使用Firebase Cloud 消息传递（FCM）HTTP API从您自己的后端触发推送通知 . 但你无法做到
- 将通知发送到Firebase用户标识符（UID）和
- 向用户细分发送通知（在用户控制台上定位属性和事件） .
含义：您必须自己存储FCM / GCM注册ID（推送令牌）或使用FCM主题订阅用户 . 还要记住 FCM is not an API for Firebase Notifications ，这是一个没有调度或开放率分析的低级API . Firebase Notifications Build 在FCM的顶部 .

或者您可以使用Firebase Cloud 功能，这对我来说是实现推送通知的更简单方法 . firebase/functions-samples

这适用于CURL

function sendGCM($message, $id) {


    $url = 'https://fcm.googleapis.com/fcm/send';

    $fields = array (
            'registration_ids' => array (
                    $id
            ),
            'data' => array (
                    "message" => $message
            )
    );
    $fields = json_encode ( $fields );

    $headers = array (
            'Authorization: key=' . "YOUR_KEY_HERE",
            '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_POSTFIELDS, $fields );

    $result = curl_exec ( $ch );
    echo $result;
    curl_close ( $ch );
}

?>

$message 是您要发送到设备的消息

$id 是 devices registration token

YOUR_KEY_HERE 是您的服务器API密钥（或旧服务器API密钥）

如果你想从android发送推送通知，请查看我的博文

Send Push Notifications from 1 android phone to another with out server.

发送推送通知只是对https://fcm.googleapis.com/fcm/send的发布请求

使用齐射的代码片段：

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);

我建议大家查看我的博文，了解完整的详细信息 .

使用Firebase Console，您可以根据应用程序包向所有用户发送消息 . 但是使用CURL或PHP API是不可能的 .

通过API您可以向特定设备ID或订阅用户发送通知，以选择主题或订阅的主题用户 .

使用服务API .

网址： https://fcm.googleapis.com/fcm/send

方法类型： POST

头：

Content-Type: application/json
Authorization: key=your api key

车身/有效载荷：

{ "notification": {
    "title": "Your Title",
    "text": "Your Text",
     "click_action": "OPEN_ACTIVITY_1" // should match to your intent filter
  },
    "data": {
    "keyname": "any value " //you can get this data as extras in your activity and this data is optional
    },
  "to" : "to_id(firebase refreshedToken)"
}

在您的应用中，您可以在要调用的活动中添加以下代码：

<intent-filter>
    <action android:name="OPEN_ACTIVITY_1" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>
