Question

我有一个网页https://freddiemac.embs.com/FLoan/secure/login.php，我需要提供登录信息，然后在成功登录后，我将登陆不同的网页https://freddiemac.embs.com/FLoan/Data/download.php，我需要在其中勾选条款＆amp;条件复选框，然后单击继续，页面刷新以显示我需要下载的一堆zip文件。

我使用以下代码登录网站：

import urllib
import urllib.request
import http.cookiejar

payload = {'username': 'username', 'password': 'password','submit': 'Submit Credentials'}

cj = http.cookiejar.CookieJar()
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
login_data = urllib.parse.urlencode(payload)
binary_data = login_data.encode('utf8')

opener.open('https://freddiemac.embs.com/FLoan/secure/login.php', binary_data)
resp = opener.open('https://freddiemac.embs.com/FLoan/Data/download.php')

print(resp.read())

我的结果低于结果，我觉得这只是https://freddiemac.embs.com/FLoan/secure/login.php页面的内容。

嗨Prashant Vikram Singh。我知道你刚才问过这个问题，但是当我自己寻找同一个问题的答案时，我遇到了你的问题。关键是要使用auth.php进行身份验证，然后传递您接受条款和条件。代码如下。希望这可以帮助您或任何遇到同样问题的人。

import requests

def get_freddie_links(payload1,payload2):
"""
This function takes in the data payloads for two http post to Freddie Mac Website, returns the list of issuance
disclosure files. 
"""
with requests.Session() as sess:
    response = sess.post('https://freddiemac.embs.com/FLoan/secure/auth.php',data=payload1)
    final_url = sess.post('https://freddiemac.embs.com/FLoan/Data/download2.php',data=payload2)
return final_url.text

singlefamily_payload = {'username' : <USERNAME>,'password' : <PASSWORD>}
payload2={'accept': 'Yes','acceptSubmit':'Continue','action':'acceptTandC'}
results = get_freddie_links(singlefamily_payload,payload2)

无法使用Python从网站获取结果
