我正在尝试访问我学校的内部网以进行网络搜索并使用我必须完成的作业检索表格，我在网上搜索任何解决方案但我找不到任何解决方案。出于显而易见的原因，我不会提供登录凭据，但我会提供html数据。任何帮助都很棒，谢谢。
我的代码到目前为止：
import requests
while True:
Post_Login_URL = 'http://parents.netherhall.org/'
Request_URL = 'https://parents.netherhall.org/parents/students/?admissionno=011161&page=homework'
username = input('What is your username? ')
password = input('What is your password? ')
payload = {
'username': username,
'password': password
}
with requests.Session() as session:
post = session.post(Post_Login_URL, data=payload)
r = session.get(Request_URL)
print(r.text)
我得到的回应：

您必须设置请求标头，因为默认情况下，User-Agent类似于“python请求”。
要执行此操作，请打开浏览器，如果您使用的是Chrome，请按Cntrl + E，如果您使用的是Firefox，请按Cntrl + Shift + E.然后转到网络。现在登录网站，在左侧（或下方）将出现一行代表对parents.netherhall.org的请求。单击它并复制标题。
然后像这样实现它们：
from requests import Session
# Create headers dict.
headers = {
'header_name': 'header_value', # and so on
}
Post_Login_URL = 'http://parents.netherhall.org/'
Request_URL = 'https://parents.netherhall.org/parents/students/?admissionno=011161&page=homework'
username = input('What is your username? ')
password = input('What is your password? ')
payload = {
'username': username,
'password': password
}
with Session() as session:
post = session.post(Post_Login_URL, headers=headers data=payload)
print(r.text) # Page source.
print('Logged in successfully:', r.ok)
