在 Node.js 上读取静态文件

Question

我正在尝试通过模块 NET（带套接字）构建自己的静态 Web 服务器， 我想为文本文件（html，js，css ...）编写响应和为img文件（jpg，gif ....）编写响应，

我试图用 createReadStream 和 readFile 来做，它可以工作，但它一直卡在加载中， 而且图片有时不工作...

FS.stat(fileSystemAddress + request.fileName, function (err, stat) {
    if (err) {
        // Error handling
    } else {
        if (typeImg[request.fileType] != undefined) {
            response.headers['Content-Length'] = stat.size;
            response.headers['Content-Type'] = typeImg[request.fileType];
            response.writeImg(200);
            var fileStream = FS.createReadStream(fileSystemAddress + request.fileName);
            fileStream.pipe(response.socket, {
                end: false
            });
        }
    }
});

if (typeFile[request.fileType] != undefined) {
    FS.readFile(fileSystemAddress + request.fileName, 'utf8', function (err,data) {
        if (err) {
            // Error handling
        } else {
            response.headers['Content-Length'] = data.length;
            response.headers['Content-Type'] = typeFile[request.fileType];
            response.writeFile(200,data);
        }
    });
}

还有 writeFile、writeImg 方法：

this.writeImg = function (code) {
    this.status(code);
    this.title = that.protocol + "/" + that.httpVersion + " " + that.statusCode.name + " " + that.statusCode.message  + "\r\n";
    this.socket.write(that.title + that.responseTime + "Content-Type:" + that.headers["Content-Type"] + "\r\n" + "Content-Length: " + that.headers["Content-Length"]   + "\r\n"  + "\r\n");
}
this.writeFile = function(code,body){
    this.status(code);
    this.title = that.protocol + "/" + that.httpVersion + " " + that.statusCode.name + " " + that.statusCode.message  + "\r\n";
    console.log(that.title + that.responseTime + "Content-Type:" + that.headers["Content-Type"] + "\r\n" + "Content-Length: " + that.headers["Content-Length"]   + "\r\n"  + body);
    this.socket.write(that.title + that.responseTime + "Content-Type:" + that.headers["Content-Type"] + "\r\n" + "Content-Length: " + that.headers["Content-Length"]   + "\r\n"  + "\r\n" + body);
}

知道我可以做些什么来管理文件和图像，而不会让网络卡在加载上（顺便说一下，它的本地服务器，所以它应该可以快速运行）？谢谢。

最近这里的另一个线程建议http://expressjs.com/，这是一个基于 node.js 的应用程序框架，它不仅处理本地资源的查找，还提供过滤器实现（他们称之为中间件）用于身份验证、缓存标头和许多其他的东西。
