1. Create routing processing definition

//获取http模块
var http = require(&#39;http&#39;);
//文件 模块
var fs = require(&#39;fs&#39;);

//404文件
var error = "./view/404.html";
//实现文件 相应函数以及404错误相应函数 
var Response = function (res, filePath) {
    //读取 文件，然后给客户端 相应
    fs.readFile(filePath, function (err, data) {
        if (err) {
            if (filePath != error) //如果出错输出404页面
                Response(res, error);
        } else {
            res.writeHead(200, { &#39;Content-Type&#39;: &#39;text/html&#39; });
            res.end(data);
        }
    });

2. Create a server and monitor routing processing

//创建和启动服务器
var server = http.createServer(function (req, res) {
    console.info(req.url);
    //判断 URL，提供 不同的路由
    var url = req.url;
    if (url == &#39;/index&#39; || url == &#39;/&#39;) {
        //主页
        var index = require(&#39;../view/index&#39;);
        index.write(res);
    } else {
        //制定文件输出view下的文件内容
        Response(res, &#39;./view&#39; + url);
    }
});
//启动服务器
server.listen(&#39;3000&#39;, function () {
    var address = server.address();
    console.info(address);
    console.info(&#39;服务器启动成功：http://localhost:%s&#39;, address.port);
});

3. Home page module response

/**
 * 主页内容响应处理
 */
exports.write=function(res){
    res.writeHead(200,{&#39;Content-Type&#39;:&#39;text/html&#39;});
    res.write(&#39;<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />&#39;);
    res.write(&#39;<h1>主页内容2</h1>&#39;);
    res.end();
}
