node 之 apache

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);
    }
  });
