Python SUDS-询问WSDL中的MinOccurs和MaxOccurs值 [英] Python SUDS - Interrogating the WSDL for MinOccurs and MaxOccurs values

问题描述

我想使用SUDS询问WSDL以获取Web服务的参数和属性.我几乎只剩下最后一件事了.如何查询服务以查找参数的minOccurs和maxOccurs值?

I would like to interrogate a WSDL using SUDS to get the parameters and attributes of a web service. I'm pretty much down to this one last thing. How do I interrogate the service to find the minOccurs and maxOccurs values of the parameters?

我看到suds.xsd.sxbase对象中有一个名为required的属性，但是，假设我的出发点是客户端对象，则看不到该属性的路径.

I see there's a property in the suds.xsd.sxbase object called required, but, assuming my starting point is the client object, I don't see path to get to it.

http://jortel.fedorapeople. org/suds/doc/suds.xsd.sxbase-pysrc.html#SchemaObject.required

client = Client(endpoint, username=username, password=password)
client.service[0][method]

如何确定参数是否绑定?

How can I find out if a parameter is bound?

谢谢！

推荐答案

您可以向工厂解析器查询该方法，并使用children()方法查看其参数.

you can query the factory resolver for the method, and use the children() method to see its parameters.

示例，对于这种方法，我有wsdl:

example, for this method I have my wsdl:

<complexType name="AddAuthorizationRoleRequestType">
   <sequence>
      <element name="_this" type="vim25:ManagedObjectReference" />
      <element name="name" type="xsd:string" />
      <element name="privIds" type="xsd:string" minOccurs="0" maxOccurs="unbounded" />
   </sequence>
</complexType>

我可以通过以下方式获取属性:

I can get the attributes via:

>>> a=client.factory.resolver.find("ns0:AddAuthorizationRoleRequestType")
>>> priv_el=a.children()[2][0]
<Element:0x107591a10 name="privIds" type="(u'string', u'http://www.w3.org/2001/XMLSchema')" />
>>> priv_el = a.children()[2][0]
>>> priv_el.max
unbounded
>>> priv_el.min
0

不是很优雅，但是可以用

not very elegant, but it works
