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，因为它没有换行）：

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doctor class来修复架构，但作为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来修复/纠正架构的经验？

Ewall 的资源非常好。如果您尝试搜索suds trac票证，您可能会看到其他人遇到问题similar to yours，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。

问题是你的wsdl包含   引用的模式定义   （...）但无法导入   该   “http://schemas.xmlsoap.org/soap/encoding/”   命名空间（和关联的模式）   正常。架构可以修补   运行时使用模式ImportDoctor   如下所述：   https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs

这是一个相当常见的问题。

通常引用的架构（即   未导入）是SOAP部分5   编码模式。现在可以修复此问题   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。这可能是一种尝试错误的方法。

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。祝你好运！

Python / Suds：未找到类型：'xs：complexType'
