怎么办您确定不会因为..而遇到问题吗。。在您的响应中使用。sendfile../public/abcd.html？更多信息：
var event= require('./models/event');
var url = require('url');
var fs = require("fs");
//var app1 = require('../../app').app;
module.exports = function(app, passport,io)
{
//app.get('/createevent',event.createevent);
app.get('*', function(request, response)
{
var path = url.parse(request.url).pathname;
//use request object to get user data
//response.render('index');
switch(path){
case '/':
/*response.writeHead(200, {'Content-Type': 'text/html'});
response.write('hello world');*/
//response.json({ message: 'hello' });
//response.sendfile('../../public/abcd.htm', {root: __dirname })
