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

标签: python web-services soap wsdl zeep

Python:2.7.6

zeep:1.1.0

我正在尝试访问Web服务URL的WSDL端点。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,我得到响应并且可以看到服务。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>

我已粘贴下面的完整错误。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

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

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

我不确定为什么它可以通过浏览器/ curl工作,但不是python SOAP客户端。我的端点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!

首先我想到的是,你是否在防火墙后面?这不是有线错误,只是因为无法访问URL。

对于大多数公司环境,您可以通过浏览器访问URL,但不能从命令行(或python库)访问它。原因是,公司策略已应用于您的计算机,浏览器使用代理脚本(pac)文件来确定要使用的代理。

如果您可以分享如何测试网址,这将非常有用。

您能否只使用命令ping来测试该URL是否可访问。

在我的情况下,似乎从

更改我的url端点
http://12.345.678.90:8080/PathGoesHere?wsdl

http://12.345.678.90:8080/PathGoesHere?singleWsdl

做了这个伎俩
