Question

我在服务器端使用Express和Socket.io，但我不能使用app.js，我需要如何在Express路线中使用SocKet.io。

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});    
    });  
});
...

这项工作还可以，但我有其他路线配置我的方法，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();

如何在routesActividad.js和其他路由中使用socket，以便使用emit或scoket.on y此路由

app.js

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

感谢

您好，您只需要通过参数将IO实例传递给外部模块：

app.js

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

<强> 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

如何在带有node.js的快速路由中使用socket.io
