使用Python Suds和Cisco Axl获取正确的属性嵌套

Question

我一直在尝试用Python来让Cisco Call Manager的AXL工作，而不是用php（在php上我已经没问题了），但是遇到了一些麻烦。我花了好几个小时在这个问题上纠结，所以我想请教一下大家，看看有没有人能给我一些建议。

下面是我整理过的代码：

from suds.client import Client
from suds.transport.https import HttpAuthenticated
import logging

logging.basicConfig(level=logging.CRITICAL)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.CRITICAL)
logging.getLogger('suds.xsd.schema').setLevel(logging.CRITICAL)
logging.getLogger('suds.wsdl').setLevel(logging.CRITICAL)

service = 'https://IPADDRESS:PORT/axl/'

wsdl = 'file:///PATH/TO/LOCAL/WSDL/AXLAPI.wsdl'

username = "username"

password = "password"

client = Client(wsdl, location = service, transport = HttpAuthenticated(username = username, password = password))

name = "NAME_DP"

tags = ["regionName"]

print "<THIS IS A LISTDEVICEPOOL REQUEST>"
dp = client.factory.create('ns0:ListDevicePoolReq')
dp.searchCriteria.name = name
dp.returnedTags = tags
result = client.service.listDevicePool(dp)
print "<THIS IS THE RESULT>"
print result

问题是，soap的输出结果变成了：

DEBUG:suds.client:headers = {'SOAPAction': u'"CUCM:DB ver=8.5 listDevicePool"',
'Content-Type': 'text/xml; charset=utf-8'}
ERROR:suds.client:<?xml version="1.0" encoding="UTF-8"?>

你可以看到，它把所有东西（包括我定义的searchCriteria）都放在了searchCriteria这个属性里面，这导致返回的returnedTags属性被当作searchCriteria的一部分。我现在搞不清楚为什么会这样，也不知道该怎么修正。是不是wsdl导入的时候出了问题？

如果你需要查看我导入的wsdl或xsd文件，请告诉我。它们比较大，我这台电脑无法访问pastebin或google docs（在公司被封了），但我可以找个地方把它们上传。

非常感谢你的帮助！

这是处理listPhone的代码，但它也应该适用于listPoolDevice。你可以在你的代码中使用调试和日志记录命令，结合我的代码，看看你的请求在发送时应该是什么样子。我觉得这样做能解决你的问题，并帮助你开始使用Python与CUCM和AXL进行交互。

from suds.client import Client

cmserver = '10.10.10.10'
cmport = '8443'
wsdl = 'file:///your/system/path/schema/current/AXLAPI.wsdl'
location = 'https://' + cmserver + ':' + cmport + '/axl/'
username = 'username'
password = 'password'

client = Client(wsdl,location=location, username=username, password=password)

result = client.service.listPhone({'name':'SEP%'},{'name':'','model':''})

for node in result['return']['phone']:
    print str(node['name']), str(node['model'])
