Android client receives message push from Faye

Android client receives message push from Faye Mar 3rd, 2014 Basic Principles

First read the 260 Mes-saging with Faye section of rails-casts to understand the basic principles of Faye.

According to the tutorial, Google solved the thin bug and later found that rubych-ina should have encountered similar problems.

The solution is to addFaye::WebSocket.load_adapter('thin')

require 'faye'Faye::WebSocket.load_adapter('thin')faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 45)run faye_server

Of course, in theory, Faye supports various web servers. Faye is used because it is closely related to Rails. If more concurrency is considered, select Node .? Js is also good, and faye also has a Node version.

Implementation

After the web end is implemented, consider porting it to the android Client

Google an-droid faye, found that someone has made an Android-based faye-cli-ent, according to the web-socket protocol, it is not difficult to implement one.

Compare the js Code of the faye Client

$(function() {  var faye = new Faye.Client('http://localhost:9292/faye');  faye.subscribe('/messages/new', function (data) {  alert(data);  });});

And An-droid-Faye-Cli-ent java code

URI uri = URI.create(String.format("ws://%s:443/events", baseUrl));String channel = String.format("/%s/**", User.getCurrentUser().getUserId());mClient = new FayeClient(uri, channel);mClient.setFayeListener(this);mClient.connectToServer(null);

We know how to implement it. We need to point out that the js client uses the http protocol directly, while what we need on the java side is the ws protocol (that is, Web-Socket, wss is similar to https and is an enhanced security edition of ws)

If you are using An-droid Stu-diobuild.gradleAdd the following dependency:

dependencies {    compile 'com.saulpower.fayeclient:library:1.0'}

Because this application is based on Ruby-China, you can view the source code of the home page of RubyCh-ina on the port number. The chan-nel number is also visible in the home page source code, with a tem-p_ac-cess _-token, this token is specifically used for faye chan-nel number, this token can be obtained through the api of the first version.

<script type="text/javascript" data-turbolinks-eval=false>  ROOT_URL = "http://ruby-china.org/";  ASSET_URL = "http://l.ruby-china.org/";  FAYE_SERVER_URL = "http://ruby-china.org:8080/faye";    CURRENT_USER_ACCESS_TOKEN = "72a47853462c91db8f7ed8d3d8899d00";  if (FAYE_SERVER_URL) {    App.initNotificationSubscribe();  }</script>

In the RubyCh-in-a4Android, the user gets the tem-p_ac-cess _-token and registers Ser-veice when logging on. Next, if someone @ you in the forum, you should be able to receive the message push on your mobile phone.

Source Code

All of the above Code can be found in the RubyCh-in-a4Android
