Question

在我的应用程序中使用socket.io与node.js.Receiving主应用程序文件中的客户端事件工作正常。但是在其他node.js模块中接收事件对我不起作用。任何人都可以帮助我。< / p>

客户端js文件

  var fullName=$("#fullName").val();
  var emailId=$("#emailId").val(); 
  var contactNo=$("#ContactNo").val();
  var msg=$("#message").val();
  var userInfo={fName:fullName,email:emailId,contactNumber:contactNo,message:msg};
  var socket = io.connect('http://localhost:8000');
  socket.emit('uploadResume',userInfo);

app.js - 服务器端主文件

  var express = require('express')
               , http = require('http');

  var app = express();
  app.configure(function(){
     app.use(express.static(__dirname + '/public'));
  });
 var server = http.createServer(app);
 var io = require('socket.io').listen(server);
 server.listen(8000);

 exports.io=io;
 console.log('io object is set.');
 var mongodb = require('mongodb');
 var server = new mongodb.Server("localhost", 27017, {});

 new mongodb.Db('test', server, {w: 1}).open(function (error, client) {


    exports.client = client;
    console.log('client object is set.');

 });

Notification.js

 console.log('Notification module is called');

var app=require('../server');
console.log('app module is ready to use.');
var ioObj=app.io;
var clientObj=app.client;

ioObj.sockets.on('connection', function (socket) {
socket.on('uploadResume', function (userInfo) {
 console.log('data is '+userInfo); 
 var collection = new mongodb.Collection(clientObj, 'test_collection');
  collection.insert(userInfo,{safe:true},function(err, objects) {
    if(!err){

     console.log('Data inserted successfully.');
    }
    if (err && err.message.indexOf('E11000 ') !== -1) {
      // this _id was already inserted in the database
    }
  });




   });
 });

在主应用文件上

，您必须包含模块

app.js

  var notification=require('./Notifications.js');  // module included
  var express = require('express'),
  http = require('http');

  var app = express();
  app.configure(function(){
     app.use(express.static(__dirname + '/public'));
  });
 var server = http.createServer(app);
 var io = require('socket.io').listen(server);
 server.listen(8000);

 exports.io=io;
 console.log('io object is set.');
 var mongodb = require('mongodb');
 var server = new mongodb.Server("localhost", 27017, {});

 new mongodb.Db('test', server, {w: 1}).open(function (error, client) {


    exports.client = client;
    console.log('client object is set.');

 });

因此，如果您未将模块文件包含在主app.js文件中，则无法正常工作
