Question

我正在尝试让机器人登录phpbb3论坛，我可以在urllib中进行。但是，因为它需要会话ID等，所以当您更改页面时它不会保持登录状态（我认为这是问题）。所以我正在尝试使用requests，但我甚至无法登录requests，即使使用urllib轻松登录也是如此。

#!/usr/bin/env python3

import urllib
import http.cookiejar
from bs4 import BeautifulSoup

username = ''
password = ''

cj = http.cookiejar.CookieJar()
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj))
opener.addheaders = [('User-agent','Mozilla/5.0')]

auth_url = "http://www.mingeford365.co.uk/forum/ucp.php?mode=login"
payload  = {'username' : username, 'password' : password, 
            "autologin" : "on", 'login' : 'Login'}

data = urllib.parse.urlencode(payload)
binary_data = data.encode('UTF-8')

req = urllib.request.Request(auth_url,binary_data)
resp = urllib.request.urlopen(req)
contents = resp.read().decode('UTF-8')

if username in contents:
   print('logged in.')

以上代码有效。以下请求代码不起作用

    #!/usr/bin/env python3
import requests
from bs4 import BeautifulSoup

url = 'http://www.mingeford365.co.uk/forum/ucp.php?mode=login'

logininfo = {'username': '',
             'password': '',
             'autologin' : "on", 
             'login' : 'Login'}

headers = {'User-Agent' : 'Mozilla/5.0 (x11; Ubuntu; Linux x86; rv:28.0) Gecko/20100101 Firefox/28.0'}
           #'Accept': 'text/html, application/xhtml+xhtml,application/xml;q=0.9,*/*;q=0.8',
           #'Accept-Language': 'en-gb,en;q=0.5', 
           #'Accept-Encoding':  'gzip, deflate',                                   
           #'referer': 'http://www.mingeford365.co.uk/forum/index.php',
           #'Connection' : 'keep-alive',
           #'Content-Type': 'application/x-www-form-urlencoded'}

session = requests.Session()
get_session_id = session.get("http://www.mingeford365.co.uk/forum",headers=headers)
print(get_session_id.status_code)

response = session.post(url,params=logininfo,headers=headers) #cookies=get_session_id.cookies
soup = BeautifulSoup(response.text)

print(soup.get_text())

Answer 1

您将POST主体参数放在URL中。使用data，而不是params：

response = session.post(url, data=logininfo, headers=headers)

为什么这个基本的urllib代码有效，但这个基本的请求代码不行？
