1、根據(jù)規(guī)則去解析鏈接,并且獲取ID或者索引值

//請求路徑,http://localhost/movies/1
let index = req.pathObj.base;

2、根據(jù)索引獲取數(shù)據(jù)

let movies = [
    {
        name:"雪暴",
        brief:"雪暴簡介",
        author:"張震"
    },
    {
        name:"少年的你",
        brief:"少年的你簡介",
        author:"周冬雨"
    },
]
let pageData = movies[index]

3、根據(jù)模板渲染頁面

res.render(movies[index],'./template/index.html')

4、底層需要實(shí)現(xiàn)渲染函數(shù),通過正則匹配,找到需要修改的地方進(jìn)行一一修改

function render(options,path) {
    fs.readFile(path,{encoding:"utf-8",flag:"r"},(err,data)=>{
        if(err){
            console.log(err)
        }else{
            let reg = /\{\{(.*?)\}\}/igs
            let result;
            while (result = reg.exec(data)){
                //去除兩邊的空白
                let strKey = result[1].trim()
                let strValue = options[strKey]
                data = data.replace(result[0],strValue)
            }

            this.end(data)
            
        }
    })
}
