使用readdir获取指定路径下的所有文件名
文件结构
实现代码
const fs = require('fs'); fs.readdir('G:/pink_code/Node_Study/02',(err,list) => { if (!err) { console.log(list); } }) 复制代码
代码输出
[ '01_http-helloWorld.js', '02_使用readdir获取指定路径下的所有文件名.js', 'www' ] 复制代码
在浏览器中使用模板引擎
1. 安装art-template
npm install art-template 复制代码
2. 通过script标签引入art-template
<script src="./node_modules/art-template/lib/template-web.js"></script> 复制代码
3. 使用模板引擎语法进行调用
<script src="./node_modules/art-template/lib/template-web.js"></script> <script type='text/template' id = 'tpl'> 这是{{name}} </script> <script> const test = template('tpl',{ name: 'China' }); console.log(test); </script> 复制代码
在Node中使用模板引擎
1. 安装art-template
npm install art-template 复制代码
2. 在需要使用模板引擎的模块中加载art-template
3. 查文档，使用模板引擎的API
在Node中使用模板引擎的一个小案例
const template = require('art-template'); const test = template.render('hello {{name}}',{ name: 'NodeJs' }) console.log(test); 复制代码
输出结果
hello NodeJs 复制代码
一个使用模板引擎渲染HTML的小案例

Node代码
const http = require('http'); const template = require('art-template'); const fs = require('fs'); const server = http.createServer(); server.on('request', (req, res) => { const url = req.url; // 文件路径 const filePath = 'G:/pink_code/Node_Study/02'; // 获取文件路径下所有的文件名 let listName; fs.readdir(filePath, (err, list) => { if (!err) { listName = list; } }) // 读取模板文件内容 fs.readFile('./www/template.html', (err, data) => { if (!err) { data = data.toString(); test = template.render(data,{ files: listName }) res.end(test); } else { console.log('读取文件出错', err); } }); }) // 监听3000端口 server.listen(3000, (err) => { if (!err) { console.log('服务器启动成功！'); } }) 复制代码
实现效果
