python使用cookie asp.net发布请求

Question

请提供帮助。我试图在一个需要cookie的.asp网站上创建一个POST请求，但我处理它们的方式似乎没有返回任何内容。仔细阅读一些类似主题的问题，但找不到一些人所指的_SessionID cookie。请帮助我制定此POST请求，使其有效。

response = s.get(url, headers=headers, data=data, params=params)
if response:
print(response.content)
else:

get请求不使用数据参数，您的代码是requests.get，对吗？我可以得到一个html页面与：

headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0',
}
url = 'https://safer.fmcsa.dot.gov/CompanySnapshot.aspx'
response = requests.get(url, headers=headers, verify=False)
print(response.text)
