我正在尝试使用RobotFramework测试soap 1.2服务。到目前为止,我们只使用RobotFramework的suds库测试了soap 1.1服务,并且suds与soap 1.2不兼容。
向后兼容性是新服务的一种选择,但最好有一个更长期的解决方案。我不是一个经验丰富的程序员,但如果告诉我要编辑什么以及在哪里编辑,我可以编辑代码。
在我们对使用suds的soap 1.2服务的测试中发生的情况是:suds无法解释它从Web服务获得的响应,并给出以下错误:SAXParseException::159:229:不匹配的标记
soap消息很好,在SoapUI中使用它没有问题。
我在网上发现了一些片段,建议我可以让suds库与soap 1.2一起工作,用于我的RobotFramework测试。但我几乎没有编程经验,也不知道如何将这些片段合并到sud中。有人在这个片段上评论说,这解决了他使用RobotFramework和suds的问题。
有人愿意解释我是如何做到这一点的吗?我一个人似乎想不通。如有任何建议,我们将不胜感激。
from suds.client import Client
from suds.bindings import binding
import logging
USERNAME = 'username'
PASSWORD = 'password'
# Just for debugging purposes.
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
# Telnic's SOAP server expects a SOAP 1.2 envelope, not a SOAP 1.1 envelope
# and will complain if this hack isn't done.
binding.envns = ('SOAP-ENV', 'http://www.w3.org/2003/05/soap-envelope')
client = Client('client.wsdl',
username=USERNAME,
password=PASSWORD,
headers={'Content-Type': 'application/soap+xml'})
# This will now work just fine.
client.service.someRandomMethod()

简而言之,Suds不支持SOAP 1.2绑定。发展早就停止了。因此,SudsLibrary也不支持它。
我使用示例服务SOAP 1.1/1.2观察到的一些差异是:
- HTTP头
Content-Type
:- 1.2=
"application/soap+xml"
- 1.1=
"text/xml"
- 1.2=
- HTTP标头
- 1.2=
Action
- 1.1=
SOAPAction
- 1.2=
Envelope Namespace
- 1.2=
"http://www.w3.org/2003/05/soap-envelope"
- 1.1=
"http://schemas.xmlsoap.org/soap/envelope/"
- 1.2=
下面的示例中分别实现了一个单独的解决方案。内容类型可能被覆盖。可以添加Action,但不能删除SOAPAction。还可以使用扩展库覆盖命名空间。如果您的服务忽略SOAPaction头属性,那么这应该对您有效。
