1、根据规则去解析链接,并且获取ID或者索引值

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

2、根据索引获取数据

let movies = [
    {
        name:"雪暴",
        brief:"雪暴简介",
        author:"张震"
    },
    {
        name:"少年的你",
        brief:"少年的你简介",
        author:"周冬雨"
    },
]
let pageData = movies[index]

3、根据模板渲染页面

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

4、底层需要实现渲染函数,通过正则匹配,找到需要修改的地方进行一一修改

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)){
                //去除两边的空白
                let strKey = result[1].trim()
                let strValue = options[strKey]
                data = data.replace(result[0],strValue)
            }

            this.end(data)
            
        }
    })
}
