    iwjw.com 的房源,全部是空页面,肿么办?

    headers = {
    'Cookie':'IW_UUID2_COOKIES=6a2030687b904bb8bce1c6846c99b1a6; IW_UUID_COOKIES=e3e01670134042d494cd70c725c4698f; iw_user_last_housetype_h5=2; Hm_lvt_3a10bbf8b4afa9e5ab91d66b6944e813=1461846272,1461846860; Hm_lpvt_3a10bbf8b4afa9e5ab91d66b6944e813=1461909938; iw_user_last_housetype=2'
    }
    url = 'http://m.iwjw.com/sale/shanghai/?kw=%E5%8F%A4%E6%A1%90%E5%85%AC%E5%AF%93'
    web_data = requests.get(url,headers=headers)
    soup = BeautifulSoup(web_data.text,'lxml')

    得到的结果:

    用浏览器 dev tool 看看有没有 ajax 数据包,转为抓数据包
