我的应用程序是用Python(2.7)写的，应该使用一个客户端来调用SOAP网络服务，这个服务的描述在一个WSDL文件里（这个文件是由Magento(1.7.0)生成的，放在最后）。

为这个任务选择了Suds(4.0)，当我尝试用以下代码连接时：

from suds.client import Client       
client = Client(url)

我收到了一个TypeNotFound错误，这是一个众所周知的问题，详细情况可以在这里查看 https://fedorahosted.org/suds/wiki/Documentation#FIXINGBROKENSCHEMAs

然后我把代码改成了：

from suds.client import Client
from suds.xsd.doctor import Import, ImportDoctor
#Fixing the import
imp = Import('http://schemas.xmlsoap.org/soap/encoding/')
imp.filter.add('urn:Magento')
client = Client(self.url, plugins=[ImportDoctor(imp)] )
#Now Authentication
session = client.service.login(username, password)
#Call a method
client.service.call(session,'catalog_product.info',['123'])

但是，现在又出现了一个新的异常：

File "/home/david.gonzalez/.virtualenvs/testlib/lib/python2.7/site- packages/suds/mx/literal.py", line 86, in start
    raise TypeNotFound(content.tag)
suds.TypeNotFound: Type not found: 'args'

我不明白，为什么它找不到'args'的类型，明明在wsdl里是明确写出来的：

我感觉可能是命名空间的名字有问题，不过我已经尝试过这个讨论串，结果还是一样： SOAP suds和让人头疼的Schema Type Not Found错误

soap wsdl suds exceptionhandling webservices typemismatch magento namespacing

这是你要调用的内容：

client.service.call(session,'catalog_product.info',['123']) # <--- ['123']

可能需要 xsd:anyType[] 才能正常工作；换句话说，需要一个 anyType 的数组，而不是单个的 anyType。

<message name="call">
   <part name="sessionId" type="xsd:string" />
   <part name="resourcePath" type="xsd:string" />
   <part name="args" type="xsd:anyType[]" />
