问题描述
我正在使用带有express的socketIO。在我的项目中,我有一个登录页面和一个主页。
当我成功登录时,我导航到localhost:3000 / home,我收到这个错误:
GET http: //localhost:3000/socket.io/?EIO=3&transport=polling&t=1418187395022-0 404(未找到)
我没有在我的app.js(由express创建的项目)中进行任何修改。
Index.js:
var express = require('express');
var router = express.Router();
var http = require('http');
var fs = require('fs');
var io = require('socket.io')(http);
/ * GET主页。 * /
router.get('/',function(req,res){
res.render('index',{title:'Express'});
});
router.get('/ home',function(req,res){
res.render('home',{title:'Express'});
} );
io.on('connection',function(socket){
console.log(User Connected);
socket.on('chat message',function msg){
io.emit('chat message',msg);
console.log(Message);
});
socket.on('disconnect' ,function(msg){
console.log(User DisConnected);
});
});
router.post('/ authenticate',function(req,res){
fs.readFile(./ public / Verification / Users.json,utf8,function错误,数据){
if(err)
console.log(err);
else {
var result = JSON.parse(data);
for var i = 0; i< result.Users.length; i ++){
if(req.body.username == result.Users [i] .username&& req.body.password == result。用户[i] .password){
console.log(Success !!!!!!!!!!!!!);
res.location(home);
res.redirect(home);
}
}
}
});
});
module.exports = router;
当我浏览到localhost:3000 / home时,我会收到此错误。我是新来的socketIO和express。
请告诉我是否缺少某些东西。
谢谢

在我的layout.jade中,我定义了这样的socketio:
script(src ='https://cdn.socket.io/socket.io-1.2.0.js')
如果您正在运行Express 4,在我看来,像是缺少代码行:
var app = express();
var server = app.listen(3000);
这将启动您的Web服务器并将其设置为端口3000.看到骨骼简单的Express 4应用程序在这里:
然后,要启动socket.io,您将添加:
var io = require('socket.io )。听(服务器);
而且,不需要这一行:
var http = require('http');
I am using socketIO with express.
In my project I have a login page and a home page.When i do successful login i navigate to localhost:3000/home where I get this error :
GET http://localhost:3000/socket.io/?EIO=3&transport=polling&t=1418187395022-0 404 (Not Found)
I did not do any modification in my app.js(project created by express ).
Index.js :
var express = require('express');
var router = express.Router();
var http = require('http');
var fs = require('fs');
var io = require('socket.io')(http);
/* GET home page. */
router.get('/', function(req, res) {
res.render('index', { title: 'Express' });
});
router.get('/home', function(req, res) {
res.render('home', { title: 'Express' });
});
io.on('connection', function(socket){
console.log("User Connected");
socket.on('chat message', function(msg){
io.emit('chat message', msg);
console.log("Message");
});
socket.on('disconnect', function(msg){
console.log("User DisConnected");
});
});
router.post('/authenticate', function(req, res) {
fs.readFile("./public/Verification/Users.json", "utf8", function (err, data) {
if (err)
console.log(err);
else{
var result = JSON.parse(data);
for(var i=0;i<result.Users.length;i++){
if(req.body.username == result.Users[i].username && req.body.password == result.Users[i].password){
console.log("Success!!!!!!!!!!!!!!");
res.location("home");
res.redirect("home");
}
}
}
});
});
module.exports = router;
I get this error whenever I navigate to localhost:3000/home. I am new to both socketIO and express.Please tell me if I am missing something.
Thanks
EDIT:
In my layout.jade i defined socketio like this:
script(src='https://cdn.socket.io/socket.io-1.2.0.js')
If you're running Express 4, it appears to me like you're missing the lines of code:
var app = express();
var server = app.listen(3000);
That will start your web server and set it to port 3000. See the bone simple Express 4 app here: http://expressjs.com/4x/api.html
And, then to start up socket.io, you would add:
var io = require('socket.io').listen(server);
And, there is no need for this line:
var http = require('http');
