娛樂時間利用node爬取表情包

安裝 npm install request 

先引入需要的文件

var request = require('request');

var http = require("http")

const fs = require('fs')

const cheerio = require('cheerio')

var path = require('path')

 以上是引入 所需要的包  用到那個引入那個

大概流程就是 請求 拿數據 分析數據  獲取需要的資源  保存資源  

 

var request = require('request');
var http = require("http")
const fs = require('fs')
const cheerio = require('cheerio')
var path = require('path')

function runCode(id) {
    id++
    request({
        url: 'https://www.ivsky.com/bizhi/nvxing',
        method: "get",
        json: true,
        headers: {
            "content-type": "application/json",
        },
    }, function (error, response, body) {
        let $ = cheerio.load(body);
        $(".il_img a").each((index, item) => {
            let urlsrc = 'https://www.ivsky.com' + $(item).attr("href")
            requestSrc(urlsrc, id)
        })
    });
}

function requestSrc(url, id) {
    request({
        url: url,
        method: "get",
        json: true,
        headers: {
            "content-type": "application/json",
        },
    }, function (error, response, body) {
        let $ = cheerio.load(body);
        $(".pli img").each((index, item) => {
            saveImg('http:' + $(item).attr('src'), index + '.jpg')
        })
        setTimeout(function () {
            console.log("正在保存" + id)
            runCode(id);
        }, 5000)
    });
}

function saveImg(url, name) {
    // console.log("正在保存" + name)
    var num = parseInt(Math.random() * 10000000);
    // console.log(num)
    request(url).pipe(fs.createWriteStream(__dirname + '/imgs' + num + name));
}


runCode(1);
