Powerschool登录表单数据

Question

我正试着登录PowerSchool查看我的成绩。每当我运行代码时，它给我的是登录页面的HTML代码，而不是安全页面的HTML代码。

问题1:如何获取上述代码中标记为“this changes”的3个字段的值，并将其提交给当前帖子？

问题2:我是否需要在我的密码代码中添加任何内容，这些内容在每次发布时都会被散列。

import requests


payload = {
    'pstoken': 'this changes',
    'contextData': 'this changes',
    'dbpw': 'this changes',
    'translator_username': '',
    'translator_password': '',
    'translator_ldappassword': '',
    'serviceName':' PS Parent Portal',
    'serviceTicket':'',
    'pcasServerUrl':' /',
    'credentialType':'User Id and Password Credential',
    'account':'200276',
    'pw':'my password',
    'translatorpw':''
}

head = {'User-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3180.0 Safari/537.36'}

with requests.Session() as s:
    p = s.post('https://ps.lphs.net/public/', data=payload, headers=head)

    r = s.get('https://ps.lphs.net/guardian/home.html')
    print(r.text)

编辑1：

    s.headers = {
        'User-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3180.0 Safari/537.36'}

    p = s.get('https://ps.lphs.net/guardian/home.html')
    print(p.text)

    r = s.post('https://ps.lphs.net/guardian/home.html', data=payload,
               headers={'Content-Type': 'application/x-www-form-urlencoded',
                        'Referer': 'https://ps.lphs.net/public/home.html'})

    print(r.text)

Answer 1

试试看。它应该为您获取有效的响应：

import requests

payload = {
    'pstoken': 'this changes',
    'contextData': 'this changes',
    'dbpw': 'this changes',
    'translator_username': '',
    'translator_password': '',
    'translator_ldappassword': '',
    'serviceName':' PS Parent Portal',
    'serviceTicket':'',
    'pcasServerUrl':' /',
    'credentialType':'User Id and Password Credential',
    'account':'200276',
    'pw':'my password',
    'translatorpw':''
}

with requests.Session() as s:
    s.headers={'User-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3180.0 Safari/537.36'}
    r = s.post('https://ps.lphs.net/guardian/home.html',data=payload,
                headers={'Content-Type': 'application/x-www-form-urlencoded',
                        'Referer':'https://ps.lphs.net/public/home.html'})
    print(r.text)

顺便说一句，更改payload中的参数(如果需要)即可登录。
