nodejs怎么把html以源码的形式在网页中显示了，而不是解析它。

代码如下

var fs = require('fs');

function start(response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.end(fs.readFileSync(__dirname + '/index.html')); }

function upload(response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.end(fs.readFileSync(__dirname + '/index1.html')); }
