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，我想写文本文件（html，js，css ...）的响应和img文件的响应（jpg，gif ....），

我尝试使用createReadStream和readFile来实现它，并且它可以工作，但它一直在加载，并且图片有时不起作用......

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，为了管理文件和图像，我可以做些什么，而不会阻止网络加载（顺便说一下它的本地服务器，所以它应该快速工作）？谢谢。

这里的另一个线程最近建议http://expressjs.com/，一个位于node.js之上的应用程序框架，它不仅处理本地资源的查找，还提供过滤器实现（它们称之为中间件）用于身份验证，缓存头，还有很多其他的东西。
