这是我的代码:
var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var socket = require('./sockets/socket')
var routes = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
/// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
app.set('port', 2000);
var server = app.listen(app.get('port'), function() {
console.log('Express server listening on port ' + server.address().port);
});
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
console.log('connection')
});
module.exports = app;
我试着把端口放到:
app.set('port', 2000);
var server = app.listen(app.get('port'), function() {
console.log('Express server listening on port ' + server.address().port);
});
作为3000
,这与express正在运行的内容相同(但我无法看到该数字的来源),但它显示错误,因为它显然已经被express使用了。但是,这意味着客户端socket.io在localhost:3000
转到localhost:2000
时会获得404。所有教程都让他们进入同一个端口,我不知道为什么这不起作用。
很抱歉这篇文章的清晰度很差 - 我真的在这里过头了!
