我是python的新手,我遇到了同样的问题,这个问题在GitHub请求中被提出来了。我正在尝试对初次登录后重定向到安全问题的网站进行身份验证。初始登录页面和后续页面都使用相同的"操作URL"在第二篇帖子请求我收到404,这是我的代码,任何帮助将不胜感激,在询问GitHub上的问题后,他们说这是一个问题,因为它不是在他们的结束。 (虽然他们的GitHub上有一个关于此的问题):
from bs4 import BeautifulSoup as bs
import requests
import time
sources = ["https://www.dandh.com/v4/view?pageReq=dhMainNS"]
req = requests.Session()
def login():
authentication_url = "https://www.dandh.com/v4/dh"
header = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; rv:60.0) Gecko/20100101 Firefox/60.0"}
payload = {"Login": "12345",
"PW": "12345",
"Request": "Login"}
payload2 = {"securityAnswer": "12345",
"Request": "postForm"}
req.post(authentication_url, data=payload, headers=header)
time.sleep(3)
req.post(authentication_url, data=payload2, headers=header)
time.sleep(3)
def print_object(sources):
for url in sources:
soup_object = bs(req.get(url).text, "html.parser")
print(soup_object.get_text())
def main():
login()
print_object(sources)
main()
答案 0 :(得分:0)
浏览网站后,发现问题的严重部分取决于payload2
,您只需向其中添加另一个项目:"formName":"loginChallengeValidation"
,因此总体payload2
应该看起来像这样的东西:
payload2 = {"formName":"loginChallengeValidation","securityAnswer": your_security_answer,
"Request": "postForm"}
这将阻止您获取状态代码404
。希望这会有所帮助。
尽管这是您所提问题中的问题,但我仍然怀疑这是您真正想要的(因为第1部分中的代码会将您重定向到另一种验证表单)。为了访问网站本身,您必须添加以下几行:
header2 = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; rv:60.0) Gecko/20100101 Firefox/60.0", "Referer":"https://www.dandh.com/v4/view?pageReq=LoginChallengeValidation"}
和
req.post("https://www.dandh.com/v4/view?pageReq=LoginChallengeValidation", headers=header)
因此您的最终代码应如下所示:
from bs4 import BeautifulSoup as bs
import requests
import time
sources = ["https://www.dandh.com/v4/view?pageReq=dhMainNS"]
req = requests.Session()
def login():
authentication_url = "https://www.dandh.com/v4/dh"
header = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; rv:60.0) Gecko/20100101 Firefox/60.0"}
header2 = {"user-agent": "Mozilla/5.0 (Windows NT 10.0; rv:60.0) Gecko/20100101 Firefox/60.0", "Referer":"https://www.dandh.com/v4/view?pageReq=LoginChallengeValidation"}
payload = {"Login": your_username,
"PW": your_pasword,
"Request": "Login"}
payload2 = {"formName":"loginChallengeValidation","securityAnswer": your_security_answer,
"Request": "postForm", "btContinue": ""}
req.post(authentication_url, data=payload, headers=header)
req.post("https://www.dandh.com/v4/view?pageReq=LoginChallengeValidation", headers=header)
time.sleep(3)
req.post(authentication_url, data=payload2, headers=header2)
time.sleep(3)
def print_object(sources):
for url in sources:
soup_object = bs(req.get(url).text, "html.parser")
print(soup_object.get_text())
def main():
login()
print_object(sources)
main()
(PS:您应将your_username
,your_password
和your_security_answer
替换为您的凭据)
另外,我想指出,我认为time.sleep(3)
在代码中没有用。
真的希望这会有所帮助。
