使用underscore模块的template功能实现对HTML的数据注入
- 安装underscore
代码是：npm i underscore
- 查看是否安装成功
server.js文件
var http = require('http');
const fs = require('fs');
var _ = require("underscore");
var server = http.createServer();
server.on('request', function (req, res) {
var music = {
Id: 1002,
title: '梦里水乡',
singer: '老八秘制小汉堡',
type: '奥利给'
}
const url = req.url;
if (url === '/show') {
fs.readFile(__dirname + url + '.html', 'utf-8', function (err, data) {
if (err) {
res.end(err.message);
} else {
var compiled = _.template(data);//解析执行函数
var htmlstr = compiled(music);//调用函数，注入数据
res.end(htmlstr);//显示页面
}
})
} else {
res.end('404 not found!!!!!!');
}
});
server.listen(3000, "127.0.0.1", function () {
console.log("server is listening 127.0.0.1:3000");
});
