SSL连接使用的.pem证书使用Python(SSL Connection Using .pem C

我试图使用认证的HTTPS连接建立成功的通信。我在Ubuntu 12.04使用Python 2.7版瓦特/ Django的1.4。

我下面的API文档有认证的具体要求。包括Authentication头，你会发现下面并发送证书信息。

这是代码：

import httplib
import base64

HOST = 'some.host.com'
API_URL = '/some/api/path'

username = '1234'
password = '5678'

auth_value = base64.b64encode('WS{0}._.1:{1}'.format(username, password))
path = os.path.join(os.path.dirname(__file__), 'keys/')
pem_file = '{0}WS{1}._.1.pem'.format(path, username)

xml_string = '<some><xml></xml><stuff></stuff></some>'

headers = { 'User-Agent'     : 'Rico',
            'Content-type'   : 'text/xml',
            'Authorization'  : 'Basic {0}'.format(auth_value),
          }



conn = httplib.HTTPSConnection(HOST, cert_file = pem_file)
conn.putrequest("POST", API_URL, xml_string, headers)
response = conn.getresponse()

我收到以下错误：

Traceback:
File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response
  111.                         response = callback(request, *callback_args, **callback_kwargs)

为什么会出现这个错误？

更新1：我一直在使用.pem他们给我的文件（链接点网关），但已经阅读证书文件应包含证书和RSA私钥。那是对的吗？我试图发送一个.pem含有文件，并收到以下错误：

    Traceback:
File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response

Exception Value: [Errno 336265225] _ssl.c:351: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib

我不知道这是否是向前或向后的一步。

更新2：我试图通过这两个证书文件，并创建连接对象时的密钥文件。

conn = httplib.HTTPSConnection(HOST, cert_file = pem_file, key_file = key_file)

我得到以下错误：

Traceback:

如果我尝试并结合证书文件和密钥文件并把它作为证书的说法，我收到了同样的错误。

这似乎是一些在Python中“更上一层楼”库不具备处理此类认证的连接。经过尝试的许多天，我终于能够拿出一个解决方案下降到插座的水平。

host = 'some.host.com'
service = '/some/api/path'
port = 443

# Build the authorization info
username = '1234'
password = '5678'
path = '/path/to/key/files/'
pem_file = '{0}WS{1}._.1.pem'.format(path, username)
key_file = '{0}WS{1}._.1.key'.format(path, username)
auth = base64.b64encode('WS{0}._.1:{1}'.format(username, password))

## Create the header
http_header = "POST {0} HTTP/1.0\nHost: {1}\nContent-Type: text/xml\nAuthorization: Basic {2}\nContent-Length: {3}\n\n"
req = http_header.format(service, host, auth, len(xml_string)) + xml_string

## Create the socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
conn = ssl.wrap_socket(sock, keyfile = key_file, certfile = pem_file)
conn.connect((host, port))
conn.send(req)

response = ''
while True:
    resp = conn.recv()
    response += resp

    if (resp == ''):
        break

我希望有人认为这是有用的。这种特殊的实施与链接点网关与Python（不是第一数据（链接点）支持）接口。谈论一场噩梦整个项目已。哈哈

总之，对于使用链接点任何人遇到麻烦，请注意，该.key它们提供的文件不足以在Python中创建一个连接。

openssl rsa -in orig_file.key -out new_file.key

然后使用new_file.key代替。
