url="https://passport.csdn.net/account/login"  # 登录页的网址
s = requests.Session()  # 创建一个回话
response = s.get(url)  # 获得登录页面
soup = BeautifulSoup(response.text)
lt = soup.form.find("input",{"name":"lt"})["value"]  # 获得隐藏字段
execution = soup.form.find("input",{"name":"execution"})["value"]  # 获得隐藏字段
eventId = soup.form.find("input",{"name":"_eventId"})["value"]  # 获得隐藏字段
