Question

我想在index.html请求时加载http://localhost:4935/，因此我的代码就像

const MODULES_DIR = '/usr/local/lib/node_modules/';
const APP_PORT = 4935;

var express = require(MODULES_DIR + 'express'),
    app = express(),
    http = require('http'),
    server = http.createServer(app),
    io = require(MODULES_DIR + 'socket.io').listen(server),
    fs = require('fs'),
    path = require('path');

server.listen(APP_PORT);

app.get('*', function (req, res) {
    if (fs.existsSync(__dirname + req.route.params))
        res.sendfile(__dirname + req.route.params);

    if (req.route.params == '/')
        res.sendfile(__dirname + '/index.html');
});

在此我得到错误：

web@web-X501A1 ~ $ node '/home/web/www/nodechat/server.js' 
   info  - socket.io started

http.js:691
    throw new Error('Can\'t set headers after they are sent.');
          ^

    at /usr/local/lib/node_modules/express/node_modules/send/lib/send.js:323:10
    at Object.oncomplete (fs.js:107:15)

我从错误中了解问题是res.sendfile只能发送一次......基本上我需要自动加载所有JS和CSS。

而不是：

app.get('*', function (req, res) {
  ...
});

使用此：

app.use(express.static(__dirname));

如何自动加载Express中的自定义文件？
