如何在node.js中的不同路由中使用socket.io [英] How to use socket.io across diffrent routes in node.js

问题描述

我的节点js 应用程序中有不同的路由，我必须在中使用 socket.io 每个路径使我的节点和反应js 应用程序实时。但是，我的节点js 应用程序具有以下结构。

I have different routes in my node js application and i have to use socket.io in every route to make my node and react js application realtime. But, i have the below structure of my node js application.

router.js

const express = require('express');
const router = express.Router();

const worksheetController = require('../controllers/worksheet')
const attendenceController = require('../controllers/attendence')

router.route('/worksheets')
 .get(
    worksheetController.getWorksheet
 )
 .post(
    worksheetController.validateWorksheet,
    worksheetController.addWorksheet,
    attendenceController.markAttendence
 )  

router.route('/attendances')
 .get(
    attendenceController.getAttendance
 )

module.exports = router;

server.js

const express = require('express');
const router = require('./router');

const app = express();
app.use('/api', router);

app.listen('5000', () => {
  console.log('Listening on port');
});

module.exports = app;

所以，我想知道

So, I want to know

1）如果我需要使用socket.io，我是否需要使用 http 模块来创建服务器。

1) Should i need to use http module to create a server, if i need to use socket.io.

2）我如何使用socket.io进行不同的路由。

2) How can i use socket.io for diffrent routes.

我找到的帖子与我在stackoverflow上的问题，这个，这个和这个。但我不认为，这对我有用。所以请帮助我。

I found posts that match's to my question on stackoverflow, which is this, this and this. But i don't think, that works for me. So please help me.

推荐答案

1. 你可以使用 http socket.io文档中的模块或其他模块供 c> socket.io


2. 我不确定你的理念。但是当你想要实现socket.io时。我认为你应该运行另一个节点应用程序。 （意思是您有2个nodejs app.1用于节点http正常，1表示socket.io应用程序）。在init socket.io app https://socket.io/docs/server-api/#new-Server-之后可以使用 path 选项的HttpServer选项。因为当您部署到生产时。你应该在代理服务器旁边运行你的socket.io应用程序（例如：nginx）。 Socket.io基本上支持多传输和协议。所以如果使用http restful。如何配置从nginx到socket.io app的连接映射，如何设置错误处理程序？。

1. You can use http module or other module in document of socket.io for to use socket.io
2. I don't sure your idea. But when you want implement socket.io. I think you should run another node app. (Meaning you have 2 nodejs app. 1 for node http normally and 1 for socket.io app). After you can use path option when init socket.io app https://socket.io/docs/server-api/#new-Server-httpServer-options. Because when you deploy to production. You should run your socket.io app with beside of proxy serve (ex: nginx). Socket.io basically support multi transport and protocol. So if use with http restful. How about config your connection mapping from nginx to socket.io app, how you setup error handler ?.

在你的情况下：
+创建新文件socket.js：

In your case: + Create new file socket.js:

// socket.js
var http = require('http')
var socket_io = require('socket.io')

function init_socket(app) {
    const server = http.Server(app)
    const io = socket_io(server, { path: 'your-path-want-for-socket-io' }) // default: /socket.io/
}

import {init_socket} from 'socket.js'
init_socket(app)
