需要下载第三方模块 art-template
npm install art-template --save
var template = require('art-template');
var html = template(__dirname + '/tpl.art', {
user: {
name: 'aui',
age:18
}
});
console.log(html);
一.初步实现apache
//初步实现apache功能
const http = require("http");
const fs = require("fs");
const path = require("path");
//任意目录地址
const wwwdir = "D:黑马文件就业班训练
odeStyexpressapache";
const server = http.createServer();
server.listen("8808", () => {
console.log("8808的服务端已经开启......");
});
server.on("request", function (req, res) {
let url = req.url;
if (url === "/") {
fs.readFile(path.join(__dirname, "/index.html"), (err, data) => {
if (err) {
return res.end("404 not found");
}
res.end(data);
});
} else if (url === "/boy.html") {
fs.readFile(path.join(__dirname, "/boy.html"), (err, data) => {
if (err) {
return res.end("404 not found");
}
res.end(data);
});
} else if (url === "/plus/login.html") {
fs.readFile(path.join(__dirname, "/plus/login.html"), (err, data) => {
if (err) {
return res.end("404 not found");
}
res.end(data);
});
}
});
分析思考:
1/每一次请求都需要去判断if...else...
2/const url = req.url //这句可以获取请求地址
//初步实现apache功能
const http = require("http");
const fs = require("fs");
const path = require("path");
//创建服务
const server = http.createServer();
//启动服务
server.listen("8808", () => {
console.log("8808的服务端已经开启......");
});
//监听请求
server.on("request", function (req, res) {
const filePath = path.join(__dirname, req.url);
let url = req.url;
fs.readFile(filePath, (err, data) => {
if (err) {
return res.end("404 not found");
}
res.end(data);
});
});
使用apache实例一个文件管理页面demo
const http = require("http");
const fs = require("fs");
const path = require("path");
const template = require("art-template");
//创建服务
const server = http.createServer();
//启动服务
server.listen("8808", () => {
console.log("8808的服务端已经开启......");
});
//监听请求
server.on("request", function (req, res) {
let url = req.url;
let urlPath = path.join(__dirname, url);
fs.stat(urlPath, (err, stats) => {
if (err) {
return res.end("404 not found");
}
console.log(stats.isFile());
if (stats.isFile()) {
//如果是普通文件
fs.readFile(urlPath, function (err, data) {
if (err) {
return res.end("404 not found");
}
res.end(data);
});
} else if (stats.isDirectory()) {
//表示一个文件系统目录,则返回true
let templateStr = fs.readFileSync("./template.html").toString();
let files = fs.readdirSync(urlPath);
let htmlStr = template.render(templateStr, { files: files });
res.end(htmlStr);
}
});
