Exchange Web服务（EWS）- 通过suds进行Exchange 2010 SOAP调用
我正在尝试通过Exchange Web Services使用suds 0.4.1发送电子邮件：
import suds
from suds.client import Client
from suds.transport.https import WindowsHttpAuthenticated
url = "file:///C:/Services.wsdl"
user = 'domain\\user'
password = "hardtoguess"
ntlm = WindowsHttpAuthenticated(username=user,password=password)
c = Client(url, transport=ntlm)
xml = ''' <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <CreateItem
MessageDisposition="SendAndSaveCopy"

Exchange and EWS :)</Body> <ToRecipients> <Mailbox>

</Message> </Items>
</CreateItem> </soap:Body></soap:Envelope>'''
attr = c.service.CreateItem(__inject={'msg':xml})
xml = ''' <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"> <soap:Body>
<ResolveNames

ReturnFullContactData="true"> <UnresolvedEntry>azadi</UnresolvedEntry>
</ResolveNames> </soap:Body> </soap:Envelope> '''
attr = c.service.ResolveNames(__inject={'msg':t})
print attr
我能够顺利进行身份验证，但我总是遇到以下错误：

如果有任何建议，我将非常感激。谢谢！

我也遇到过这个问题。不过，我只是偶尔会出现这个错误。我找到了一篇帖子提到可能的解决办法，这对我有一点帮助（我遇到错误的次数少了），但并没有完全解决问题。
问题似乎是Exchange服务器在发送有效响应之前就关闭了连接。如果其他人能提供更多信息，我将非常感激。这件事让我很头疼。
也许这对你有帮助： urllib2在打开一个网址时抛出错误，而在浏览器中正常打开
我不确定你是否已经这样做了，但我需要设置我的脚本来本地下载messages.xsd、types.xsd和services.wsdl，并进行修补，代码如下：
def setup(self):
'''Patches the WSDL file to include a service tag. Returns path to
local WSDL file.'''
trans = self.transport
try:
makedirs(self.localdir)
except OSError:
# Directory already exists
pass
# Download messags.xsd file
messages_url = '%s/messages.xsd' % self.urlprefix
with open('%s/%s' % (self.localdir, 'messages.xsd'), 'w') as msg_xsd:
msg_xsd.write(trans.geturl(messages_url, trans.authtype))
# Download types.xsd file
types_url = '%s/types.xsd' % self.urlprefix
with open('%s/%s' % (self.localdir, 'types.xsd'), 'w') as types_xsd:
types_xsd.write(trans.geturl(types_url, trans.authtype))
# Modify WSDL to add service description
service_url = '%s/Exchange.asmx' % self.urlprefix
servicexml = '''
<wsdl:service name="ExchangeServices">
<wsdl:port name="ExchangeServicePort" binding="tns:ExchangeServiceBinding">
<soap:address location="%s"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>''' % service_url
localwsdl = '%s/%s' % (self.localdir, 'Services.wsdl')
wsdlxml = trans.geturl(self.wsdl, trans.authtype)
with open(localwsdl, 'w') as wsdl:
wsdl.write(wsdlxml.replace('</wsdl:definitions>', servicexml))
return localwsdl
希望这能指引你朝正确的方向前进。用suds与Exchange进行沟通一直是个大挑战。我在这里找到了一些帮助，还有一些示例代码为我的项目提供了基础：
http://lists.fedoraproject.org/pipermail/suds/2010-September/001144.html
更新： 发送正确的SOAP头和RequestServerVersion：
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope>
<soap:Header>
<t:RequestServerVersion Version="Exchange2010"/>
</soap:Header>
<soap:Body>
</soap:Body>
</soap:Envelope>
我为了简洁省略了一些xml内容。
