server.js

var express = require('express');
var app = express();
var port = 8888;

app.get('/', function(req, res, next) {
  res.sendFile(__dirname + '/index.html');


});

app.listen(port, '0.0.0.0', function() {
  console.log('Server running at port ' + port);
});

查看服务器的代码。

你有这个：

app.get('/', function(req, res, next) {
  res.sendFile(__dirname + '/index.html');
});

…当您请求/时，它为index.html文件提供服务。
