如何在最新的mean.io中使用socket.io? [英] How to use socket.io with the latest mean.io?

问题描述

我已经获取了最新版Mean.io的副本，并注意到与以前使用的以前版本相比，存在许多更改.现在，我正在做的是创建一个非常基本的聊天应用程序，该应用程序将 socket.io 与房间一起使用.按照Socket文档中的基本设置，我必须实现以下内容:

I have fetched a copy of the latest Mean.io and noted quite a number of changes compared to the previous version I have been working with before. Now, what I am doing is creating a very basic chat application that uses socket.io with rooms. Following the basic setup in the Socket documentation I have to implement the following:

var app = require('express')()
  , server = require('http').createServer(app)
  , io = require('socket.io').listen(server);

server.listen(80);

app.get('/', function (req, res) {
  res.sendfile(__dirname + '/index.html');
});

io.sockets.on('connection', function (socket) {
  socket.emit('news', { hello: 'world' });
  socket.on('my other event', function (data) {
    console.log(data);
  });
});

我在哪里定义基本的插座间设置?

Where would I define the basic socket room setup?

socket.set("log level", 1);  
var people = {};  
var rooms = {};  
var clients = [];  

推荐答案

您可以将socket.io设置为在服务器上监听

You can set the socket.io to listen on your server on

/server/config/system/bootstrap.js

需要socket.io模块

Require the socket.io module

var express = require('express'),
    appPath = process.cwd(),
    io      = require('socket.io');

现在将socket.io设置为监听您的应用

Now set the socket.io to listen on your app

// Express settings
var app = express(); 
require(appPath + '/server/config/express')(app, passport, db);
io = io(app.listen(3000));    

return io;

然后，您需要在bootstrapDependencies()函数上将socket.io对象注入到您的应用中.

Then you need to inject the socket.io object into your app on bootstrapDependencies() function.

function bootstrapDependencies() {
    ...

    // Register socket.io dependency
    mean.register('io', function() {
        return io;
    });
}

均值.使用此项目进行依赖项注入 https://www.npmjs.org/package/dependable

Mean.uses this project for its dependency injection https://www.npmjs.org/package/dependable

最后，您需要配置您的应用程序以侦听每个套接字连接 可能您想在主应用程序的路由器上进行以下操作

Finally you need to configure your app to listen on every socket connections probably you want to do these on your main app's router at

/server/routes/index.js

示例连接处理程序

var io = require('meanio').io;

io.on('connection', function (socket) {
    // emit data to the clients
    socket.emit('news', { hello: 'world' });

    // event listeners
    socket.on('my other event', function (data) {
         // call your controller function here
         Controller.action(data);
    });
});

更重要的是，不要忘记在客户端设置socket.io.

And more importantly, don't forget to setup socket.io on the client side.

// on '/server/views/includes/foot.html'
<script src='/socket.io/socket.io.js'></script>
<script>
    var socket = io();
</script>
