区分路由，加载外部资源

const http = require("http");  // 创建服务器
const fs = require("fs");  //  操作文件/目标
const url = require("url"); // 解析url字符串/url对象
const mime = require("./mime.json"); // 根据文件格式，获取对应的头部信息
const path = require("path");  // 处理文件路径

const server = http.createServer((req,res)=>{

    let obj = url.parse(req.url,true);
	
	// 加载主页
    if(obj.pathname == "/"){
        res.setHeader("content-type","text/html;charset=utf-8");
        let indexData = fs.readFileSync("./view/index.html");
        res.write(indexData);
    }else if(obj.pathname == "/detail"){
        res.setHeader("content-type","text/html;charset=utf-8");
        let indexData = fs.readFileSync("./view/detail.html");
        res.write(indexData);
    }else{
        if(obj.pathname !== "/favicon.ico"){
            let ext = path.extname(obj.pathname);
            console.log(ext);
            res.setHeader("content-type",mime[ext]);

            let resData = fs.readFileSync("view" + obj.pathname);
            res.write(resData);
        }
    }

    res.end();
}).listen(8008);
