带有Zeep的Python SOAP客户端 - 身份验证

标签: python authentication soap wsdl

我正在尝试使用Zeep来实现SOAP客户端,因为它似乎是目前唯一维护的库:

  • ZSI 看起来很不错,但最新版本是pypi日期2006年
  • suds 似乎是一个受欢迎的选择,但是主人自2011年以来一直没有维护,并且那里有很多分叉但似乎没有#34;官方"和"最近"足以在大型项目中使用。

因此,尝试使用Zeep时,我坚持使用服务器访问WSDL所需的身份验证。

ZSI的这种操作非常简单:

from ZSI.client import Binding
from ZSI.auth import AUTH

b = Binding(url='http://mysite.dom/services/MyWebServices?WSDL')
b.SetAuth(AUTH.httpbasic, 'userid', 'password')

我可以在Zeep的__main__.py中找到类似的内容:

from six.moves.urllib.parse import urlparse
from zeep.cache import InMemoryCache, SqliteCache
from zeep.client import Client
from zeep.transports import Transport

cache = SqliteCache() if args.cache else InMemoryCache()
transport_kwargs = {'cache': cache}
result = urlparse(args.wsdl_file)
if result.username or result.password:
    transport_kwargs['http_auth'] = (result.username, result.password)
transport = Transport(**transport_kwargs)
client = Client(args.wsdl_file, transport=transport)

但在我的情况下这不起作用,我收到一个错误:

Exception: HTTPConnectionPool(host='schemas.xmlsoap.org', port=80): Max retries exceeded with url: /soap/encoding/ (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f3dab9d30b8>: Failed to establish a new connection: [Errno 110] Connection timed out',))

可能使用较新版本的zeep,旧解决方案不再适用。 Here is the new way

from requests.auth import HTTPBasicAuth  # or HTTPDigestAuth, or OAuth1, etc.
from requests import Session
from zeep import Client
from zeep.transports import Transport

session = Session()
session.auth = HTTPBasicAuth(user, password)
client = Client('http://my-endpoint.com/production.svc?wsdl',
            transport=Transport(session=session))

对于基本访问身份验证,您可以使用HTTPBasicAuth模块中的requests类,如Zeep文档http://docs.python-zeep.org/en/master/transport.html中所述:

from requests.auth import HTTPBasicAuth  # or HTTPDigestAuth, or OAuth1, etc.
from zeep import Client
from zeep.transports import Transport

client = Client('http://my-endpoint.com/production.svc?wsdl',
    transport=Transport(http_auth=HTTPBasicAuth(user, password)))

就我而言,我使用的API是必需的WS-Security(WSSE)而不是HTTP。

from zeep import Client
from zeep.wsse.username import UsernameToken

client = Client(<wsdl_url>, wsse=UsernameToken(<username>, <password>)
