Question

我正在尝试在localhost上连接一个wamp服务器，这是一个html页面。

到目前为止，我有这个：

//SOCKET.IO Setup
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http); //initialise after http server

io.on('connection', function(socket){
  console.log('a user connected');
  socket.on('disconnect', function(){
    console.log('user disconnected');
  });
});
http.listen('/wheel', function(){
  console.log('listening on */wheel');
});

app.get('/', function(req, res){
  res.sendfile('wheel.html');
});

我在www / wheel中有HTML页面，html页面叫做wheel.html

这是我得到的错误：

[17:08:51] error  - Error: listen EACCES
    at exports._errnoException (util.js:746:11)
    at Server._listen2 (net.js:1139:19)
    at listen (net.js:1182:10)
    at Server.listen (net.js:1261:5)
    at Object.<anonymous> (C:\Family\wheel.js:14:6)
    at Module._compile (module.js:460:26)
    at Object.Module._extensions..js (module.js:478:10)
    at Module.load (module.js:355:32)
    at Function.Module._load (module.js:310:12)
    at Function.Module.runMain (module.js:501:10)

如何使用socket.io正确连接到localhost中的web目录？它在我使用套接字和端口时起作用：

http.listen(1000, function(){
  console.log('listening on *:1000');
});

app.get('/', function(req, res){
  res.sendfile('wheel.html');
});

问题在于您是否尝试让HTTP服务器在名为/的{{3}}上收听，而您没有正确的权限来创建该文件。< / p>

如果您希望能够在客户端在服务器上调用http.listen(3000); ... app.get('/', function(req, res){ res.sendfile('./www/wheel/wheel.html'); });（例如，正在侦听端口3000）时提供HTML文件：

CREATE TABLE dog
(
DogID int(6) NOT NULL,
DogName varchar(15),
medicalID int (6),
Gender character(1) check(gender in ('m', 'f')),
Age int(2),
Breed varchar(15),
size character (1) check(size in ('s', 'm', 'l')),
primary key (DogID));

CREATE TABLE Owns
(
DogID int (6)primary key,
CustomerID int (6),
foreign key (CustomerID) references customer (CustomerID),
foreign key (DogID) references dog (DogID));

CREATE TABLE customer
(
CustomerID int(6) NOT NULL,
FirstName varchar(15),
Surname varchar(15),
Address varchar(225),
email varchar (30), 
TelNo varchar (15),
MobNo Varchar (15), 
EmergencyName varchar (40), 
EmergencyPhoneNo varchar(15),
primary key (CustomerID));

socket.io http在localhost上侦听
