今天准备用SOAPpy来写一个最简单的soap client，代码如下：

#!/usr/bin/env python
# -*- encoding: utf-8 -*-

from SOAPpy import WSDL
WSDLfile = "/path/to/webservice"

wsdlObject = WSDL.Proxy(WSDLfile)

print 'Available methods:'
for method in wsdlObject.methods.keys() :
    print method
    ci = wsdlObject.methods[method]
    # you can also use ci.inparams
    for param in ci.outparams :
        # list of the function and type 
        # depending of the wsdl...
        print param.name.ljust(20) , param.type
    print

运行的时候出现了这个问题：

Traceback (most recent call last): File “remedy_ws_client.py”, line 9, in wsdlObject = WSDL.Proxy(WSDLfile) File “build/bdist.macosx-10.6-universal/egg/SOAPpy/WSDL.py”, line 85, in init File “/Library/Python/2.6/site-packages/wstools-0.3-py2.6.egg/wstools/WSDLTools.py”, line 47, in loadFromString return self.loadFromStream(StringIO(data)) File “/Library/Python/2.6/site-packages/wstools-0.3-py2.6.egg/wstools/WSDLTools.py”, line 28, in loadFromStream document = DOM.loadDocument(stream) File “/Library/Python/2.6/site-packages/wstools-0.3-py2.6.egg/wstools/Utility.py”, line 635, in loadDocument return xml.dom.minidom.parse(data) File “/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/dom/minidom.py”, line 1918, in parse return expatbuilder.parse(file) File “/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/dom/expatbuilder.py”, line 928, in parse result = builder.parseFile(file) File “/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/dom/expatbuilder.py”, line 207, in parseFile parser.Parse(buffer, 0) xml.parsers.expat.ExpatError: not well-formed (invalid token): line 1, column 5

查了很久，最后发现是因为公司网络需要代理的缘故，造成python不能连接网络。解决办法就是:
