Node.js快速创建一个访问html文件的服务器

var http = require('http'), // 引入需要的模块
  fs = require('fs'), //引入文件读取模块
  cp = require('child_process'), // 可自动打开浏览器模块
  url = require("url"),
  path = require("path");


http.createServer(function (req, res) {
  var pathname = __dirname + url.parse(req.url).pathname; // 对于文件路径统一处理
  if (path.extname(pathname) == "") {
    pathname += "/html/"; // 欲打开文件的目录
  }
  if (pathname.charAt(pathname.length - 1) == "/") {
    pathname += "index.html"; // 默认打开的文件
  }
  fs.exists(pathname, function (exists) {
    if (exists) {
      switch (path.extname(pathname)) { // 不同文件返回不同类型
        case ".html":
          res.writeHead(200, {
            "Content-Type": "text/html"
          });
          break;
        case ".js":
          res.writeHead(200, {
            "Content-Type": "text/javascript"
          });
          break;
        case ".css":
          res.writeHead(200, {
            "Content-Type": "text/css"
          });
          break;
        case ".gif":
          res.writeHead(200, {
            "Content-Type": "image/gif"
          });
          break;
        case ".jpg":
          res.writeHead(200, {
            "Content-Type": "image/jpeg"
          });
          break;
        case ".png":
          res.writeHead(200, {
            "Content-Type": "image/png"
          });
          break;
        case ".json":
          res.writeHead(200, {
            "Content-Type": "text/plain"
          })
          break;
        default:
          res.writeHead(200, {
            "Content-Type": "application/octet-stream"
          });
      }
      fs.readFile(pathname, function (err, data) {
        console.log((new Date()).toLocaleString() + " " + pathname);
        res.end(data);
      });
    } else { // 找不到目录 时的处理
      res.writeHead(404, {
        "Content-Type": "text/html"
      });
      res.end("<h1>404 Not Found</h1>");
    }
  });

}).listen(8088, "127.0.0.1"); // 监听端口

console.log("Server running at http://127.0.0.1:8088/");

cp.exec('start http://127.0.0.1:8088/html/project.html'); // 自动打开默认浏览器
