python - Spyne SOAP服务器的Hello世界示例

我正在尝试使用几种不同的Python SOAP服务器库，但似乎无法获得用于spyne的“ hello world”示例：
https://github.com/arskom/spyne/blob/master/examples/helloworld_soap.py

运行它时，它会启动SOAP服务器，并且可以在http://localhost:7789/?wsdl的浏览器中成功查看WSDL。但是，当我尝试与suds客户端连接时，出现异常：

Python 2.7.3 (default, Aug  1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from suds.client import Client
>>> c = Client('http://localhost:7789/?wsdl')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/client.py", line 112, in __init__
    self.wsdl = reader.open(url)
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/reader.py", line 152, in open
    d = self.fn(url, self.options)
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/wsdl.py", line 158, in __init__
    self.resolve()
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/wsdl.py", line 207, in resolve
    c.resolve(self)
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/wsdl.py", line 661, in resolve
    self.resolveheaders(definitions, op)
  File "/home/acordiner/ve/local/lib/python2.7/site-packages/suds/wsdl.py", line 725, in resolveheaders
    raise Exception, "message'%s', not-found" % mn
Exception: message's0:SomeObject', not-found

我可能做错了什么？我正在使用spyne 2.9.4和suds 0.4。

最佳答案

对此我感到抱歉。

您链接到的示例是：https://github.com/arskom/spyne/blob/ec2bd6feb89fb36915b7266497c177e4c6f78b83/examples/helloworld_soap.py

它用于说明suds错误，该错误已在my own version of suds中修复，但未在主流sud中修复。后来我忘记了将其还原到Spyne主存储库中。

您可以找到relevant commit here。

Suds无法处理名称空间与targetNamespace不同的传出标头对象。您可以通过设置SomeObject.__namespace__ = 'spyne.examples.hello.soap'而不是'aaa'来使您的suds版本起作用。

您也可以只删除在helloworld示例中不适当的传出标头声明。

我希望这有帮助。
