cheerio

数据爬虫，把请求回来的数据组合，并用过cheerio模块筛选，筛选方式跟jquery选择器用法基本相似

const http = require('http')
const https = require('https')
const cheerio = require('cheerio');
function filterData(data) {
    let $ = cheerio.load(data)
    $('.comment-img-wp img').each((index, el) => {
        console.log($(el).attr('data-src'))
    })
}
const server = http.createServer((req, res) => {
    let data = ''
    https.get('https://m.meizu.com', (result) => {
        result.on('data', (chunk) => {
            data += chunk
        })
        result.on('end', () => {
            filterData(data)
        })
    })
})
server.listen(2139, () => {
    console.log('2139succ')
})
