- html文件代码
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>我的node.js首页</title>
</head>
<body></body>
</html>
- 通过buffer流读取html文件
var fs = require('fs');
function wuwa(callback)
{fs.open('.././webpage/firstpage.html','r',function (err,fd) {var readbyte = Buffer.alloc(1024);var offset = 0;var len = readbyte.length;var readposition = null;function saiwa(callback) {fs.read(fd, readbyte, offset, len, readposition, function (err, readBytes) {if (err) throw new err('~oh,no');//console.log(readbyte.slice(0, readBytes).toString('utf8'));var ret = readbyte.slice(0, readBytes).toString('utf8');callback(ret);})}saiwa(function (data) {callback(data)})})
}
module.exports = wuwa;
- 新建一个文件调取buffer读取定义好的函数
var weirwa=require('./readwebpage');
console.log(weirwa);
weirwa(function (data) {console.log(data);
});
输出结果:
[Function: wuwa]
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>我的node.js首页</title>
</head>
<body></body>
</html>Process finished with exit code 0
- 创建server返回结果
var http = require('http');
var url = require('url');
var weirwa=require('./readwebpage');
http.createServer(function (req,res) {res.writeHead(200,{'content-Type':'text/plain; charset=UTF-8'});weirwa(function (data) {res.end(data);});console.log("url: "+url.parse(req.url));}).listen(3000);
- 输出结果
