Python Web服务：尝试使用zeep SOAP客户端连接到WSDL endpoints 会产生连接错误

Python：2.7.6

zeep：1.1.0

我正在尝试访问Web服务URL的WSDL endpoints . 我目前正在使用zeep SOAP客户端，并且还尝试了suds（并得到了类似的结果） . 当我从Web访问URL或向其发送curl请求时，我得到响应并可以看到服务 . 但是当我尝试从zeep（使用python -mzeep [url]命令）或suds（仅通过print（客户端））访问它时，我收到连接错误 .

urllib2.URLError: <urlopen error [Errno -2] Name or service not known>

我已经粘贴了下面的完整错误 . 不幸的是我无法在这里分享网址，所以我正在为我的帖子更改它 .

在我的代码中，我有以下内容

from zeep import Client
endpoint_url = 'http://12.345.678.90:8080/PathGoesHere?wsdl'
client = Client(endpoint_url)

我也尝试了以下内容

sudo python -mzeep http://12.345.678.90:8080/PathGoesHere?wsdl

错误：

我不确定它为什么通过浏览器/ curl而不是python SOAP客户端 . 我的 endpoints URL中是否应该更改某些内容，例如稍后设置端口？我尝试使用suds，因为URL无效而给了我404错误 . 我应该如何处理这个问题/我还能尝试什么？

提前致谢！
