最近為了建立預測病毒傳播的模型，需要爬取到百度遷徙上的數據，這里順手寫一下

一、找規律

首先，我們打開http://qianxi.baidu.com/，隨便查詢一個城市的資料，比如查看北京29號的資料：

可以找到數據存在這里，接下來我們看hearers

找到：Request URL: http://huiyan.baidu.com/migration/cityrank.jsonp?dt=province&id=110000&type=move_out&date=20200129&callback=jsonp_1580386984204_4388923
忽略最后一個&，我們可以發現只需找到兩個變量（id、date）對應參數，就可以批量爬取數據。date我們可以確定，現在需要找id

接下來在源碼中找到http://qianxi.cdn.bcebos.com/app/index.js?b8e016517dc0b92ce531：
打開后發現每個地區對應的id：

二、代碼：
