Question

我为访问特定网站而不是用户制作了一些代码。它与自动登录程序非常相似。我的程序从用户接收用户ID和密码，并尝试使用数据和登录访问URL，返回登录结果。

这是代码。

from urllib import urlencode
from urllib2 import Request
from ClientCookie import urlopen, install_opener, build_opener

httpheaders = {'User-Agent' : 'Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1;)'}
y_url1 = 'http://www.xxx.kr/papp.jsp'
y_url2 = 'https://im.xxx.kr/sso/auth'

def check_valid_user(user_id, user_pw):
    values = {'ssousername': user_id, 'password': user_pw}
    data = urlencode(values)
    req = Request(y_url1, data, httpheaders)
    response = urlopen(req)
    the_page = response.read()
    token = the_page.split('"site2pstoretoken"')[1].split('"')[1]
    values = {'ssousername': user_id, 'password': user_pw, 'site2pstoretoken' : token}
    data = urlencode(values)
    req = Request(y_url2, data, httpheaders)
    response = urlopen(req)
    the_page = response.read()
    install_opener(build_opener())
    if the_page.find('Cyber') == -1:
        return False
    else:
        return True

当我在Windows桌面上运行此程序时，它运行良好。

但是当我在我的ubuntu apache服务器上运行这个程序时，它无法运行。（ubuntu 11.04，python 2.7.1）

我打开django python shell并尝试逐行调试 python manage.py shell

response = urlopen(req)

此时，错误会增加。

>>>response = urlopen(req)

raise URLError(err)
URLError: <urlopen error [Errno 1] _ssl.c:499: error:14077417:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert illegal parameter>

有什么问题？请帮帮我......

Answer 1

查看此错误报告urllib bug

似乎下面的内容可能会解决它。

 import ssl
 https_sslv3_handler = urllib.request.HTTPSHandler(context=ssl.SSLContext(ssl.PROTOCOL_SSLv3))
 opener = urllib.request.build_opener(https_sslv3_handler)
 urllib.request.install_opener(opener)

Answer 2

我会使用requests代替urllib。语法更清晰：

r = requests.get('https://your-url', auth=('user', 'pass'))

您还可以添加标题：

headers = {'content-type': 'application/json'}
r = requests.get('https://your-url', auth=('user', 'pass'), headers=headers)

Answer 3

你的服务器可能不支持SSLv2，Python ssl似乎默认使用它。

看看我在这里发布的解决方案，看看它是否对您有所帮助：https://stackoverflow.com/a/24175862/41957

python：不能使用urlopen !!来自urllib，urllib2，clientcookie urlopen ssl错误
