python之Exchange Web 服务 (EWS)之通过 suds 的 Exchange 2010 soap 调用

2025年05月04日7飞鱼

我正在尝试使用 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

我能够很好地进行身份验证，但是我不断收到以下错误:

如有任何建议，我们将不胜感激。谢谢

请您参考如下方法:

我也遇到过这个问题。但是，我只是间歇性地收到此错误。我找到了另一篇提到可能解决方案的帖子，它对一些人有所帮助(我得到的错误更少)，但它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关闭了连接。如果其他人可以添加更多，我将不胜感激。这个一直让我发疯。

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

我不确定您是否已经这样做了，但我需要设置脚本以在本地下载 messages.xsd、types.xsd 和 services.wsdl 并对其进行修补。具有以下内容:

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

希望这会为您指明正确的方向。简单地用泡沫与 Exchange 交谈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 header :

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

为简洁起见，我截断了 xml。
