//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\nodeStyexpressapache";
 
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);

      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
