Exchange Web服务(EWS) - 通过suds进行Exchange 2010 soap调用

标签: python exchange-server suds exchangewebservices httplib

我尝试使用suds 0.4.1通过Exchange Web服务发送电子邮件:

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"
xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">
<SavedItemFolderId> <DistinguishedFolderId Id="sentitems"
xmlns="http://schemas.microsoft.com/exchange/services/2006/types"/> 
</SavedItemFolderId> <Items> <Message
xmlns="http://schemas.microsoft.com/exchange/services/2006/types">  
<ItemClass>IPM.Note</ItemClass> <Subject>Sent via Python->Exchange->EWS</Subject>  
<Body BodyType="Text">This message has been sent to you via Python,
Exchange and EWS :)</Body> <ToRecipients> <Mailbox> 
<EmailAddress>imran.azad@localhost</EmailAddress> </Mailbox> </ToRecipients>   
</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
xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"
xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"
ReturnFullContactData="true"> <UnresolvedEntry>azadi</UnresolvedEntry> 
</ResolveNames> </soap:Body> </soap:Envelope> ''' 

attr = c.service.ResolveNames(__inject={'msg':t})

 print attr 

我能够正常验证,但是我一直收到以下错误:

非常感谢任何建议。感谢

我也遇到过这个问题。但是,我只是间歇性地得到这个错误。我发现另一篇文章提到了一个可能的解决方案,它帮助了一些(我得到的错误更少),但它没有完全解决问题。

问题似乎是Exchange服务器在发送有效响应之前关闭了连接。如果其他人可以添加更多我会非常感激。这个让我疯狂。

也许这可以帮到你: urllib2 is throwing an error for an url , while it's opening properly in browser

我不确定你是否已经这样做了,但我需要设置我的脚本以在本地下载messages.xsd,types.xsd和services.wsdl并对其进行修补。以下内容:

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

希望这会指出你正确的方向。简单地与Exchange谈论与肥皂水一直是一个重大挑战。我在这里找到了一些帮助,以及为我的项目提供基础的示例代码:

http://lists.fedoraproject.org/pipermail/suds/2010-September/001144.html

更新: 使用RequestServerVersion发送正确的SOAP标头:

<?xml version="1.0" encoding="utf-8"?>
  <soap:Envelope>
    <soap:Header>
      <t:RequestServerVersion Version="Exchange2010"/>
    </soap:Header>
    <soap:Body>
    </soap:Body>
 </soap:Envelope>

我为了简洁而截断了xml。
