Python/Suds:未找到类型:'xs:complexType'

Question

我有以下简单的python测试脚本,它使用Suds来调用SOAP Web服务(该服务是用ASP.net编写的):

from suds.client import Client

url = 'http://someURL.asmx?WSDL'

client = Client( url )

result = client.service.GetPackageDetails( "MyPackage"  )

print result

当我运行此测试脚本时,我收到以下错误(使用代码标记,因为它不包装):

No handlers could be found for logger "suds.bindings.unmarshaller"
Traceback (most recent call last):
  File "sudsTest.py", line 9, in <module>
    result = client.service.GetPackageDetails( "t3db"  )

suds.TypeNotFound: Type not found: 'xs:complexType'

查看WSDL文件头的源代码(重新格式化为适合):

<?xml version="1.0" encoding="utf-8" ?> 
<wsdl:definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" 
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
xmlns:s="http://www.w3.org/2001/XMLSchema" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:tns="http://http://someInternalURL/webservices.asmx" 
xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" 
xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" 
targetNamespace="http://someURL.asmx" 
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">

我猜测基于最后一行输出:

suds.TypeNotFound: Type not found: 'xs:complexType'

我需要使用Sud的医生类来修复模式,但作为一个SOAP新手,我不知道在我的情况下究竟需要修复什么.有没有人有使用Suds修复/更正架构的经验？

Ewall的资源很好.如果您尝试搜索suds trac票证,您可能会看到其他人遇到与您类似的问题,但具有不同的对象类型.它可以是学习它的示例以及它们如何导入命名空间的好方法.

问题是您的wsdl包含引用(...)的模式定义,但无法正确导入" http://schemas.xmlsoap.org/soap/encoding/ "名称空间(和关联的模式).可以使用如下所述的模式ImportDoctor在运行时修补模式:https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs .

这是一个相当普遍的问题.

通常引用的模式(未导入)是SOAP部分5编码模式.现在可以修复如下:

(所有重点都是我的).

您可以尝试这些文档提供的行添加WSDL中显示的命名空间.这可能是一个尝试错误的方法.

imp = Import('http://schemas.xmlsoap.org/soap/encoding/')
# Below is your targetNamespace presented in WSDL. Remember
# that you can add more namespaces by appending more imp.filter.add
imp.filter.add('http://someURL.asmx') 
doctor = ImportDoctor(imp) 
client = Client(url, doctor=doctor)

你没有提供你正在使用的WSDL,我想你有理由不向我们展示......所以我认为你必须自己尝试这些可能性.祝好运!
