html5 - express4 + socket.io 如何在connection的回调外边使用socket.emit方法

Question

app.js

    var sockect = require('./socket/server')
    var users = require('../router/users')
    
    app.use('/users', users); //路由
    
    var server = app.listen(9000, function () {
        console.log('server start');
    });
    
    sockect(server); //启动socket

server.js

'use strict';

module.exports = function(server) {
    var io = require('socket.io').listen(server);
    io.sockets.on('connection', function (socket) {
        //如何将这里的socket暴露给其他地方的js方法里使用socket.emit ?
    });
    return io;

};

上面是我目前的结构，希望在users里面的逻辑里触发emit方法，google了很多，也没有找到有什么办法可以将参数socket传递出去，不然的话所有逻辑只要涉及到socket.emit的都要写在connection的回调里..

Answer 1

In the server.js file:

var users = require('../router/users')
module.exports = function(server) {
    var io = require('socket.io').listen(server);
    io.sockets.on('connection', function (socket) {
        //如何将这里的socket暴露给其他地方的js方法里使用socket.emit ?
        users.doSomething(socket);
    });
    return io;

};

Then write business logic in users.js

Answer 2

I also encountered this problem, please solve it

Answer 3

I also think that within the scope of external calls socket没什么意义。。
而且express和socket两者走的协议都不一样,
你可以把user的身份信息保存在 局部变量socket
use identification information to perform corresponding user operations

Answer 4

Same question, how to expose the socket object? ? ? ?
