python - 不知道发布搜索按钮的 btnSearch.x 和 btnSearch.y 值

Question

不知道 btnSearch.x 和 btnSearch.y 值用于发布搜索按钮以使用以下参数单击搜索按钮？

payload={
    'today':'20180806'
    'sortBy':'',
    'alertMsg':'', 
    'ddlShareholdingDay':'04',
    'ddlShareholdingMonth':'06', 
    'ddlShareholdingYear':'2018', 
    'btnSearch.x':'????',
    'btnSearch.y':'???'
}

import requests
from bs4 import BeautifulSoup
html = "url"
r=requests.post(html, data=payload)
c=r.content
soup=BeautifulSoup(c,"html.parser")

all_tables=[[td.text for td in tr.find_all('td')] for tr in 
soup.find_all('table')[2].find_all('tr')]
stock_info=[[sub_item.replace('\r\n', '') for sub_item in item] for item in all_tables]
for stock in stock_info[2:]:
    print stock

Answer 1

btnSearch.x 和 btnSearch.y 值并不重要，它们只是 btnSearch 图像的鼠标坐标(我认为) ，并且对 POST 请求没有任何影响。

但是，ASP.NET Web 应用程序会使用一些重要的隐藏字段(__VIEWSTATE、__EVENTVALIDATION)。我们可以找到这些值并将它们与 POST 数据一起提交。

import requests
from bs4 import BeautifulSoup

url = 'url'
s = requests.session()
r = s.get(url)
soup = BeautifulSoup(r.text, 'html.parser')

data = {i['name']: i.get('value') for i in soup.select('input')}
data['ddlShareholdingDay'] = '04'
data['ddlShareholdingMonth'] = '06'
data['ddlShareholdingYear'] = '2018'
data['btnSearch.x'] = '????'
data['btnSearch.y'] = '???'

r = s.post(url, data)
soup = BeautifulSoup(r.text, 'html.parser')
stock_info = [
    [td.text.strip() for td in tr.find_all('td')] 
    for tr in soup.find_all('table')[2].find_all('tr')
]
for stock in stock_info[2:]:
    print(stock)
