如何在node.js的快速路由中使用socket.io [英] How use socket.io in express routes with node.js

问题描述

我在服务器端将Socket.io与Express一起使用，但是我不能在app.js中使用它，我需要如何在Express路由中使用SocKet.io.

I'm using Express with Socket.io in the server side but i can't use out of app.js, i need how to use SocKet.io in Express routes.

app.js

...  
let http = require('http').Server(app);
let io = require('socket.io')(http);

io.on('connection', (socket) => {
    console.log('user connected');
    socket.on('disconnect', function(){
        console.log('user disconnected');
    });
    socket.on('message', (message) => {
        console.log("Message Received: " + message);
        io.emit('message', {type:'new-message', text: message});    
    });  
});
...

这个工作还可以，但是我还有其他路线可以在其中配置我的方法，POST，GET ... EX

this work ok, but i have other routes where configure my methods, POST, GET ... EX

routesActividad.js

...
function http(){ 

  this.configActividad= function(app){
    // get actividades by id
    app.get('/actividad/:NUM_ID_EMPLEADO', function(req, res) {
    //... code here...//
      .then(function (actividad) {              
        res.json(actividad);
      }).catch(error => res.status(400).send(error));
    })

   app.post('/actividad/', function(req, res){
    // code here //
   })

   app.put('/actividad/', function(req, res){
    // code here //
   })
  }
}

module.exports = new http();

我如何在routesActividad.js和其他类似路由中使用套接字，以便在此路由上使用emit或scoket.

how i can use socket in routesActividad.js and other routes like this, for use emit or scoket.on y this routes

app.js

...
var routesActividad = require('./routes/routesActividad');
    routesActividad.configActividad(app);
// more routes
...

谢谢

推荐答案

您好，您只需要按参数将IO实例传递给外部模块即可:

Hello you just need to pass the IO instance by parameter to your external module:

app.js

let http = require('http').Server(app);
let io = require('socket.io')(http);
let actividad = require('routesActividad')(io);

routesActividad.js:

function http(io){ 

   //put the IO stuff wherever you want inside functions or outside



  this.configActividad= function(app){
    // get actividades by id
    app.get('/actividad/:NUM_ID_EMPLEADO', function(req, res) {
    //... code here...//
      .then(function (actividad) {              
        res.json(actividad);
      }).catch(error => res.status(400).send(error));
    })

   app.post('/actividad/', function(req, res){
    // code here //
   })

   app.put('/actividad/', function(req, res){
    // code here //
   })
  }
}

module.exports = http; //Removed new statement
