执行某些步骤后无法获取从网页动态填充的号码

Question

我使用 requests 模块和 BeautifulSoup 库创建了一个脚本来从网页中获取一些表格内容。要生成该表，必须手动按照我在所附图片中显示的步骤进行操作。我在下面粘贴的代码是一个有效的代码，但我试图解决的主要问题是以title编程方式获取数字，在本例中，628086906该数字附加到table_link我在此处硬编码的代码。

单击第 6 步中的工具按钮后，当您将光标悬停在地图上时，您可以看到此选项，Multiple当您单击该选项时，您将转到包含标题编号的 url。

首页

这正是脚本所遵循的步骤。

0030278592这是第 6 步中需要在输入框中输入的linc 编号。

我尝试过（工作之一，因为我在 中使用了硬编码的标题编号table_link）：

import requests

from bs4 import BeautifulSoup

link = 'https://alta.registries.gov.ab.ca/spinii/logon.aspx'

lnotice = 'https://alta.registries.gov.ab.ca/spinii/legalnotice.aspx'

search_page = 'https://alta.registries.gov.ab.ca/SpinII/SearchSelectType.aspx'

map_page = 'http://alta.registries.gov.ab.ca/SpinII/mapindex.aspx'

map_find = 'http://alta.registries.gov.ab.ca/SpinII/mapfinds.aspx'

table_link = 'https://alta.registries.gov.ab.ca/SpinII/popupTitleSearch.aspx?title=628086906'

def get_content(s,link):   

    r = s.get(link)

    soup = BeautifulSoup(r.text,"lxml")

    payload = {i['name']:i.get('value','') for i in soup.select('input[name]')}

    payload['uctrlLogon:cmdLogonGuest.x'] = '80'

    payload['uctrlLogon:cmdLogonGuest.y'] = '20'

    r = s.post(link,data=payload)

    soup = BeautifulSoup(r.text,"lxml")

    payload = {i['name']:i.get('value','') for i in soup.select('input[name]')}

    payload['cmdYES.x'] = '52'

    payload['cmdYES.y'] = '8'

    s.post(lnotice,data=payload)

    s.headers['Referer'] = 'https://alta.registries.gov.ab.ca/spinii/welcomeguest.aspx'

    

    s.get(search_page)

    s.headers['Referer'] = 'https://alta.registries.gov.ab.ca/SpinII/SearchSelectType.aspx'

    

如何从 url 中获取标题编号？

或者

如何从该站点获取所有 linc 号码，以便我根本不需要使用地图？

The only problem with this site is that it is unavailable in daytime for maintenance.

Answer 1

数据调用自：POST&nbsp;http://alta.registries.gov.ab.ca/SpinII/mapserver.aspx内容在被OpenLayers 库使用之前以自定义格式进行编码。所有的解码都位于这个JS文件中。如果你美化了，你可以找一下它的WayTo.Wtb.Format.WTB解码OpenLayers.Class。二进制文件按照 JS 中的如下所示逐字节解码：switch(elementType){&nbsp; &nbsp; case 1:&nbsp; &nbsp; &nbsp; &nbsp; var lineColor = new WayTo.Wtb.Element.LineColor();&nbsp; &nbsp; &nbsp; &nbsp; byteOffset = lineColor.parse(dataReader, byteOffset);&nbsp; &nbsp; &nbsp; &nbsp; outputElement = lineColor;&nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; case 2:&nbsp; &nbsp; &nbsp; &nbsp; var lineStyle = new WayTo.Wtb.Element.LineStyle();&nbsp; &nbsp; &nbsp; &nbsp; byteOffset = lineStyle.parse(dataReader, byteOffset);&nbsp; &nbsp; &nbsp; &nbsp; outputElement = lineStyle;&nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; case 3:&nbsp; &nbsp; &nbsp; &nbsp; var ellipse = new WayTo.Wtb.Element.Ellipse();&nbsp; &nbsp; &nbsp; &nbsp; byteOffset = ellipse.parse(dataReader, byteOffset);&nbsp; &nbsp; &nbsp; &nbsp; outputElement = ellipse;&nbsp; &nbsp; &nbsp; &nbsp; break;&nbsp; &nbsp; ........}我们必须重现这个解码算法才能获得原始数据。我们不需要解码所有对象，我们只想获得正确的偏移量并strings正确提取。这里有一个Python解码部分的脚本，用于解码文件中的数据（输出卷曲):with open("wtb.bin", mode='rb') as file:&nbsp; &nbsp; encodedData = file.read()&nbsp; &nbsp; offset = 0&nbsp; &nbsp; objects = []&nbsp; &nbsp; while offset < len(encodedData):&nbsp; &nbsp; &nbsp; &nbsp; elementSize = encodedData[offset]&nbsp; &nbsp;

有两种选择可以获取您正在寻找的信息，其中一种是您可能已经知道的硒。当您将鼠标悬停在地图上时，打开网络选项卡并监视浏览器传递的请求是否向服务器发出请求。对于请求和 BS4，您最好的选择是如果数据已经加载，那么下面的解决方案可能会起作用import&nbsp;re&nbsp; print(re.findall(r’628086906’,&nbsp;r.text)&nbsp;)如果它打印出数字，则意味着数据在 json 中可用并随页面一起加载，您可以加载 json 或使用正则表达式查找。否则你唯一的选择是硒
