python webservice: from SOAPpy import WSDL
我在用SOAPpy.WSDL 时也遇到了这个问题，希望高手路过时指点一下：
>>> from SOAPpy import WSDL
>>> url = "http://211.137.45.104:9006/LnXxtCpInterface/services/LNXxtSyncService?wsdl"
>>> server = WSDL.Proxy(url)
/usr/lib/pymodules/python2.6/SOAPpy/wstools/XMLSchema.py:2871: DeprecationWarning: object.__init__() takes no parameters
tuple.__init__(self, args)
>>> server = WSDL.Proxy(url)
>>> server.methods.keys()
[u'sendMo', u'syncResponseRpt', u'sendMt', u'syncStaff', u'syncCorp']
>>> server.methods['sendMt']
<SOAPpy.wstools.WSDLTools.SOAPCallInfo instance at 0xeb9ab8>
>>> server.methods['sendMt'].inparams
[<SOAPpy.wstools.WSDLTools.ParameterInfo instance at 0xeb9b00>]
>>> server.methods['sendMt'].inparams[0].type
(u'service.global.v1_0.wsdl.protocol.xxt', u'ArrayOf_soapenc_string')
>>> server.methods['sendMt'].inparams[0].name
u'mtInfo'
>>> server.methods['sendMt'].outparams[0].name
u'sendMtReturn'
>>> server.methods['sendMt'].outparams[0].type
(u'http://schemas.xmlsoap.org/soap/encoding/', u'string')
>>> server.sendMt(['a','b'])

#NOTE:
我这里只是调用了一下 sendMt() 方法，输入参数在java 中 其实就是一个 String[] ， 为什么在 这里会出现这样的错误？
[解决办法]
为什么没人回复？？
[解决办法]
几天过去了，还是没人回复； 给国外的一些论坛里发了一些，也没有完全解决； 这里将问题再描述一遍：
Hi, all:
First of all, I will admire I am a novice to web service.
What I need now is to invoke a method sendMt provided by the web service server(prehaps the
server is made by java language using a framwork named Axis).
I try to invoke the sendMt method provided by the server, then failded. There are the tests as
follows:
method 1:
import suds
def test_sms():
#TODO: it's failed
url = "http://211.137.45.104:9006/LnXxtCpInterface/services/LNXxtSyncService?wsdl"
#client = suds.client.Client(url,faults=False)
client = suds.client.Client(url)
print 'client', client
a = ['jia','xiao']
output = client.service.sendMt(a)
print 'output', output
# the output:
client
Suds ( https://fedorahosted.org/suds/ ) version: 0.3.7 GA build: R580-20091016
Service ( LNXxtSyncServiceService ) tns="service.global.v1_0.wsdl.protocol.xxt"
Prefixes (3)
ns0 = "http://common.v1_0.obj.protocol.xxt"
ns1 = "http://schemas.xmlsoap.org/soap/encoding/"
ns2 = "service.global.v1_0.wsdl.protocol.xxt"
Ports (1):

Methods (5):
sendMo(ArrayOf_soapenc_string moInfo, )
sendMt(ArrayOf_soapenc_string mtInfo, )
syncCorp(ArrayOf_tns2_GroupOrderInfo orderInfo, )
syncResponseRpt(ArrayOf_soapenc_string rpt, )
syncStaff(ArrayOf_tns2_UserOrderInfo orderInfo, )

#Note:
1: the url "http://211.137.45.104:9006/LnXxtCpInterface/services/LNXxtSyncService?wsdl" is
develped in Internet, anyone can use it.
2: in my view, the server is made by java Axis, and the inparams of sendmt is
ArrayOf_soapenc_string(In java, it means a array of String, in python, it means a list whose
items are string).
3: the problem has puzzled me for nearly a week, please someone can give me some points.
# besides the suds, i try other methods as follows, whlie, still failed.
method 2:
from SOAPpy import SOAPProxy
def test_sms():
"""test for ln sms java webservice

[解决办法]
呵呵，也许我的提问不应该放在这个地方，又或许是别的一些原因。。
现在python client --> java server 的问题基本解决了。
实现的方式是 suds.
