我在 android 模拟器上看不到 ParsePush 通知

Question

我目前正在开发一个聊天应用程序，我想实现解析服务器推送通知。 我遵循文档并放置了所需的所有代码。 我的问题是我看不到通知，即使控制台告诉我它已发送。

这是我的 MainActivity.java 哪里是 Parse 安装。

 @Override protected void onCreate(Bundle savedInstanceState) { notificationsPush(); createGraphicElements(); super.onCreate(savedInstanceState); } private void notificationsPush(){ ParseInstallation.getCurrentInstallation().saveInBackground(new SaveCallback() { @Override public void done(ParseException e) { if (e == null){ System.out.println("---------------------"); System.out.println("SUCCESS ON INSTALLATION"); System.out.println("----------------------"); ParsePush.subscribeInBackground("Chat", new SaveCallback() { @Override public void done(ParseException e) { if (e == null) { System.out.println("----------------------"); System.out.println("SUCCESS ON CHANNEL"); System.out.println("----------------------"); } else { System.out.println("----------------------"); System.out.println("ERROR ON CHANNEL: " + e.getMessage()); System.out.println("CODE: " + e.getCode()); System.out.println("----------------------"); } } }); }else{ System.out.println("---------------------"); System.out.println("ERROR ON INSTALLATION"); System.out.println("ERROR: " + e.getMessage()); System.out.println("CODE: " + e.getCode()); System.out.println("----------------------"); } } }); }

这些是我在 graddle 模块上的实现。 （还有一个是连接到 Firebase 所需的）。

 implementation platform('com.google.firebase:firebase-bom:28.4.1') implementation 'com.google.firebase:firebase-analytics' implementation 'com.google.firebase:firebase-messaging' //Parse Server implementation "com.github.parse-community.Parse-SDK-Android:parse:1.26.0" //PUSH Parse Server implementation "com.github.parse-community.Parse-SDK-Android:fcm:1.26.0"

这些是我在 ParseCloud 上使用的函数（它们在 main.js 上）。

 Parse.Cloud.define("SendPush", function(request) { var query = new Parse.Query(Parse.Installation); query.exists("deviceToken"); // here you can add other conditions eg to send a push to sepcific users or channel etc. var payload = { alert: request.params.Message // you can add other stuff here... }; Parse.Push.send({ data: payload, where: query }, { useMasterKey: true }) .then(function() { response.success("Push Sent!"); }, function(error) { response.error("Error while trying to send push " + error.message); }); }); Parse.Cloud.define("SendPush2", function(request) { var msg = request.params.Message; var query = new Parse.Query(Parse.User); var user = request.params.user; query.equalTo("objectId", user); Parse.Push.send({ where: query, data:{ alert: { "title" : msg, "body" : msg }, sound: 'default' } }, { useMasterKey: true, success: function(){ response.success("Push Sent!"); }, error: function(error){ response.error("Error while trying to send push " + error.message); } }); }); Parse.Cloud.define("SendPush3", function(request, response) { var userId = request.params.user; var message = "sening a test message"; //request.params.message; var queryUser = new Parse.Query(Parse.User); queryUser.equalTo('objectId', userId); var query = new Parse.Query(Parse.Installation); query.matchesQuery('user', queryUser); Parse.Push.send({ where: query, data: { alert: message, badge: 0, sound: 'default' } }, { success: function() { console.log('##### PUSH OK'); response.success(); }, error: function(error) { console.log('##### PUSH ERROR'); response.error('ERROR'); }, useMasterKey: true }); });

最后，我测试那些 ParseCloud 函数以发送通知的应用程序代码段。

 private void sendMessage(){ if(messageEditText.getText().toString().length() > 0) { String messageToSend = messageEditText.getText().toString(); messageEditText.setText(""); MessageBO messageBO = new MessageBO(); messageBO.setText(messageToSend); messageBO.setUserIdSender(idUser); messageBO.setUserIdReceiver(idContact); insertMessage(messageBO.getUserIdSender().toString(), messageBO.getUserIdReceiver().toString(), messageBO.getText().toString()); enviarNotificacionPush(messageBO); } actualizarMensajes(); } private void sendNotificationPush(MessageBO m){ HashMap<String,String> map = new HashMap<String, String>(); map.put("Message", m.getText().toString()); ParseCloud.callFunctionInBackground("SendPush",map, new FunctionCallback<Object>() { @Override public void done(Object object, ParseException e) { if (e == null){ System.out.println("----------------------------"); System.out.println("NOTIFICATION SUCCES: " + object); System.out.println("----------------------------"); }else{ System.out.println("----------------------------"); System.out.println("ERROR ON NOTIFICATION PUSH: " + e.getMessage()); System.out.println("CODE: " + e.getCode()); System.out.println("----------------------------"); } } }); HashMap<String,String> map2 = new HashMap<String, String>(); map2.put("Message", m.getText().toString()); map2.put("user", idUser); ParseCloud.callFunctionInBackground("SendPush2",map2, new FunctionCallback<Object>() { @Override public void done(Object object, ParseException e) { if (e == null){ System.out.println("----------------------------"); System.out.println("NOTIFICATION 2.0 SUCCESS: " + object); System.out.println("----------------------------"); }else{ System.out.println("----------------------------"); System.out.println("ERROR ON NOTIFICATION PUSH 2.0: " + e.getMessage()); System.out.println("CODE: " + e.getCode()); System.out.println("----------------------------"); } } }); ParseCloud.callFunctionInBackground("SendPush3",map2, new FunctionCallback<Object>() { @Override public void done(Object object, ParseException e) { if (e == null){ System.out.println("----------------------------"); System.out.println("NOTIFICACION 3.0 SUCCESS: " + object); System.out.println("----------------------------"); }else{ System.out.println("----------------------------"); System.out.println("ERROR ON NOTIFICACION PUSH 3.0: " + e.getMessage()); System.out.println("CODE: " + e.getCode()); System.out.println("----------------------------"); } } }); }

如您所见，我使用了 3 个发送通知的函数，它们都说它成功了，但在我的 android 模拟器中从未收到通知。 我检查了我的解析仪表板，尽管它说通知已发送，但它也说 0 次交付。 我需要你的帮助，因为我不知道我做错了什么。

如果您需要，我的 Android 模拟器的信息如下：我的 android 模拟器信息

[编辑 1]（我不知道如何引用要求我这样做的评论，但无论如何）因为我看到您可能需要安装类。 安装类由于我卸载并重新安装了应用程序，因此所有安装都来自模拟器。 有我的智能手机，那是华为（我也看不到通知，但我知道那是由于华为在谷歌服务方面的问题）。

[编辑 2] 你好，这是我的解析服务器配置（也就是我的解析的index.js ）。 顺便说一下，我正在使用parse_server_example存储库。

 // Example express application adding the parse-server module to expose Parse // compatible API routes. const express = require('express'); const ParseServer = require('parse-server').ParseServer; const path = require('path'); var ParseDashboard = require('parse-dashboard'); const args = process.argv || []; const test = args.some(arg => arg.includes('jasmine')); const databaseUri = process.env.DATABASE_URI || process.env.MONGODB_URI; if (!databaseUri) { console.log('DATABASE_URI not specified, falling back to localhost.'); } const config = { databaseURI: databaseUri || 'mongodb://admin:123@localhost:27017/ParseServer?authSource=admin', cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js', appId: process.env.APP_ID || 'MY_APP_ID', masterKey: process.env.MASTER_KEY || 'MY_MASTER_KEY', //Add your master key here. Keep it secret! serverURL: process.env.SERVER_URL || 'http://192.168.10.100:1337/parse/', // Don't forget to change to https if needed liveQuery: { classNames: ['Posts', 'Comments'], // List of classes to support for query subscriptions }, push: { android: { apiKey: 'AAAASP09btg:APA91bGxn3e0vJX0ri2DeFEWUjAODTCaP3mfCQ0la3oiIgNqNYUlj2THFlEwRjqnXGuI-8H_l5-0xZtyscn3yY4mRrAL5tNHYXrM8NBltgCwCx1gH8LFVvgAWubmV2Zsa5NkmD53vCeO' } } }; // Client-keys like the javascript key or the .NET key are not necessary with parse-server // If you wish you require them, you can set them as options in the initialization above: // javascriptKey, restAPIKey, dotNetKey, clientKey var configdashboard = { "allowInsecureHTTP": true, "apps": [ { "serverURL": "http://192.168.10.100:1337/parse/", "appId": "MY_APP_ID", "masterKey": "MY_MASTER_KEY", "appName": "ParseServer01" } ],"users": [ { "user": "root", "pass": "123456" } ] }; var dashboard = new ParseDashboard(configdashboard,{allowInsecureHTTP:configdashboard.allowInsecureHTTP}); const app = express(); app.use('/dashboard', dashboard); // Serve static assets from the /public folder app.use('/public', express.static(path.join(__dirname, '/public'))); // Serve the Parse API on the /parse URL prefix const mountPath = process.env.PARSE_MOUNT || '/parse'; if (!test) { const api = new ParseServer(config); app.use(mountPath, api); } // Parse Server plays nicely with the rest of your web routes app.get('/', function (req, res) { res.status(200).send('I dream of being a website. Please star the parse-server repo on GitHub!'); }); // There will be a test page available on the /test path of your server url // Remove this before launching your app app.get('/test', function (req, res) { res.sendFile(path.join(__dirname, '/public/test.html')); }); const port = process.env.PORT || 1337; if (!test) { const httpServer = require('http').createServer(app); httpServer.listen(port, function () { console.log('parse-server-example running on port ' + port + '.'); }); // This will enable the Live Query real-time server ParseServer.createLiveQueryServer(httpServer); } module.exports = { app, config, };

[编辑 3] 你好，我试图用 curl 发送通知，结果是这样的：

curl -X POST \

 -H "X-Parse-Application-Id: wPacsFQMmP" \\ -H "X-Parse-Master-Key: DwonoEbeNf" \\ -H "Content-Type: application/json" \\ -d '{ "where": { "deviceType": { "$in": [ "android" ] } }, "data": { "title": "The Shining", "alert": "All work and no play makes Jack a dull boy." } }'\\ http://192.168.10.100:1337/parse/push

{“结果”：真}[

另外作为附加信息，当我尝试仅使用 FCM 进行推送时（这意味着，请遵循此Firebase FCM 文档）并且结果基本相同，它表示已成功发送，但我在 android 模拟器上看不到它，甚至在我的旧智能手机（诺基亚 6）中也没有。

[编辑 4] 我打开了详细信息，这就是我在有关 SendPush 云函数的解析日志中发现的内容。

Answer 1

要为 Android 设备发送推送通知，必填字段是deviceToken和GCMSenderID 。

但是，根据您发送的屏幕截图，您安装的 GCMSenderId 为空，并且需要发送推送通知。

在您的MainActivity ，您没有明确设置它，这是正确保存它所必需的。

这是一个示例代码，展示了如何做到这一点：

 ParseInstallation installation = ParseInstallation.getCurrentInstallation();
    installation.put("GCMSenderId", INSERT_YOUR_SENDER_ID);
    installation.saveInBackground();

填写两个字段后，推送通知可能会正常工作。
