Question

我尝试通过BS4 python删除动态网站：

https://www.nadlan.gov.il/?search=%D7%AA%D7%9C%20%D7%90%D7%91%D7%99%D7%91%20%20%D7%99%D7%A4%D7%95

我尝试过：

from urllib.request import urlopen
from bs4 import BeautifulSoup
page = urlopen(wiki)
soup = BeautifulSoup("https://www.nadlan.gov.il/?search=תל אביב יפו")

我有2个问题：

网站是动态的，当我查看页面源代码时，我只看到页面内容不是JavaScript脚本：

<script>
    document.write("<script src='scripts/dis/bundleJS.js?v=" + globalAppVersion + "'><\/script>")
    document.write("<script id='srcGovmap' src='https://new.govmap.gov.il/govmap/api/govmap.api.js?v='" + globalAppVersion + "'><\/script>")
    document.write("<script src='MainLoader.js?v=" + globalAppVersion + "'><\/script>")
    document.write("<script id='tld-search-srcipt' 
src='https://www.nadlan.gov.il/TldSearch/Scripts/ac.js?v=" + globalAppVersion + "'><\/script>");
</script>

<script src="scripts/dis/accessibility/b1.js?v=3" type="text/javascript"></script>

<script type="text/javascript">

accessibility_rtl = true;
pixel_from_side = 20;
pixel_from_start = 15;

$(document).ready(function () {
    $('#accessibility_icon').attr('src', 'images/accessibility_icon.png')
    $('.accessibility_div_wrap>.btn_accessibility > span.accessibility_component').html('')
});

当我打开网站时，加载数据需要几秒钟：

我如何用硒解决这些问题？

Answer 1

数据通过JavaScript动态加载。您可以使用requests / json模块来模拟Ajax调用。例如：

import json
import requests


url = 'https://www.nadlan.gov.il/Nadlan.REST/Main/GetAssestAndDeals'
data = {"MoreAssestsType":0,"FillterRoomNum":0,"GridDisplayType":0,"ResultLable":"תל אביב -יפו","ResultType":1,"ObjectID":"5000","ObjectIDType":"text","ObjectKey":"UNIQ_ID","DescLayerID":"SETL_MID_POINT","Alert":None,"X":180428.31832654,"Y":665726.5550939,"Gush":"","Parcel":"","showLotParcel":False,"showLotAddress":False,"OriginalSearchString":"תל אביב  יפו","MutipuleResults":False,"ResultsOptions":None,"CurrentLavel":2,"Navs":[{"text":"מחוז תל אביב - יפו","url":None,"order":1}],"QueryMapParams":{"QueryToRun":None,"QueryObjectID":"5000","QueryObjectType":"number","QueryObjectKey":"SETL_CODE","QueryDescLayerID":"KSHTANN_SETL_AREA","SpacialWhereClause":None},"isHistorical":False,"PageNo":1,"OrderByFilled":"DEALDATETIME","OrderByDescending":True,"Distance":0}
result = requests.post(url, json=data).json()

# uncomment this to print all data:
# print(json.dumps(result, indent=4))

# print all results to screen:
for r in result['AllResults']:
    for k, v in r.items():
        print('{:<30} {}'.format(k, v))
    print('-' * 80)
