我在Python SUDS中遇到了另一个可怕的TypeNotFound错误（Python 2.7，suds-jurko == 0.6）
这些是XSD的相关部分：
<xs:complexType final="extension restriction" name="requestHeader">
<xs:sequence>
<xs:element minOccurs="0" name="type" type="tns:requestType"/>
<xs:element minOccurs="0" name="userID" type="xs:string"/>
<xs:element minOccurs="0" name="sessionID" type="xs:string"/>
</xs:sequence>
</xs:complexType>
<xs:complexType final="extension restriction" name="requestType">
<xs:sequence>
<xs:element name="__value" type="xs:int"/>
</xs:sequence>
</xs:complexType>
WSDL正确导入XSD，因此我不相信Doctor会提供帮助：
<wsdl:definitions
name="FooBarService"
targetNamespace="foo.bar.ns"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="foo.bar.ns"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
<schema xmlns="http://www.w3.org/2001/XMLSchema">
<import namespace="foo.bar.ns" schemaLocation="someschemafile.xsd"/>
<import namespace="http://jaxb.dev.java.net/array" schemaLocation="someschemafile2.xsd"/>
someschemafile.xsd：
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:ns1="http://jaxb.dev.java.net/array"
xmlns:tns="foo.bar.ns"
attributeFormDefault="unqualified"
elementFormDefault="unqualified"
targetNamespace="foo.bar.ns">
然后我创建requestHeader和requestType：
q = soap_client.factory.create('requestHeader')
print q
(requestHeader){
type =
(requestType){
__value = None
}
userID = None
sessionID = None
}
然后：
q.type = soap_client.factory.create('requestType')
q.type.__value = 42
q.userID = "foo"
q.sessionID = "bar"
print q
(requestHeader){
type =
(requestType){
__value = 42
}
userID = "foo"
sessionID = "bar"
}
然后我尝试调用使用requestHeader的方法，之后我得到：
TypeNotFound(u"Type not found: '__value'",)
我也试过这个：
q = {
'type': 42,
'userID': "foo",
'sessionID': "bar"
}
但这会导致错误的SOAP消息：
<header>
<type>42</type>
<userID>foo</userID>
<sessionID>bar</sessionID>
</header>
而不是
<header>
<type>
<__value>42</__value>
</type>
<userID>foo</userID>
<sessionID>bar</sessionID>
</header>
最终被服务拒绝了。
对不起，我无法提供完整的WSDL和XSD，它们受到限制。
如何使suds使用__value元素创建正确的SOAP XML？
我使用WSDL的本地副本，因此我可以更改它，只要它能够生成正确的SOAP XML。不过，我不知道该改变什么。
编辑：添加了一些清理后的回溯（在调用SUDS方法之前删除了东西）request是SUDS对象，其中一个属性属于requestHeader

答案 0 :(得分：0)
根据@dopstar评论，这是因为SUDS中的错误。由于我没有时间尝试在源代码上修复它，我设计了一些丑陋的解决方法
from lxml import etree
etree_object = build_XML_using_etree()
soap_client.service.someServiceMethod(
__inject={'msg': etree.tostring(etree_object)}
)
丑陋的部分实际上在这里看不到它是编织隐藏在build_XML_using_etree方法后面的XML的逻辑，因为我们不能在这里依赖SUDS。
另一方面，一旦将原始XML注入SUDS堆栈，其他一切工作都很顺利，所以也许这不是那么糟糕......
