代碼如下

var?http=require('http')
var?cheerio=require('cheerio')
var?html=''
var?src=[]
http.get('http://www.bilibili.com',function(res){
	res.on('data',function(data){
		html+=data
	})
	res.on('end',function(){
		$=cheerio.load(html)
		var?re=/^.*\/video\/av\d+.*/
		$('[href]').each(function(){
			src.push(this.attribs.href)		
		})
		src=src.filter(function(x){
			return?re.test(x)		
		})
		console.log(src)
	})
}).on('error',function(){
	console.log('Error')
})
