在Node.js上读取静态文件

Question

我正在尝试通过模块NET（带有套接字）构建自己的静态Web服务器，我想编写文本文件（html，js，css ...）的响应和img文件（jpg，gif ...的响应） ），

我尝试使用createReadStream和readFile来做到这一点，并且它可以正常工作，但是一直都在加载，并且图片有时无法工作...

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);
        }
    });
}

和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);
}

任何想法我该怎么办才能管理文件和图像而不会在网络上挂载（顺便说一下，它是本地服务器，所以它应该工作很快）？谢谢。

这里的另一个线程最近建议使用http://expressjs.com/ ，这是一种在node.js之上的应用程序框架，该框架不仅处理本地资源的查找，而且还提供用于身份验证的过滤器实现（它们称为中间件），缓存头，还有很多其他事情。
