【问题描述】：

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"

<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:t="http://schemas.microsoft.com/exchange/services/2006/types"> <soap:Body>

ReturnFullContactData="true"> <UnresolvedEntry>azadi</UnresolvedEntry> 
</ResolveNames> </soap:Body> </soap:Envelope> ''' 

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

 print attr

我可以正常进行身份验证，但是我不断收到以下错误：

    raise BadStatusLine(line)

任何建议将不胜感激。谢谢

【问题讨论】：

打开完整的 SUDS 日志记录以准确找出导致错误的 URL。我有一个类似的问题，原来是一个过载的 www.w3.org 服务器是问题所在。解决方案是为 www.w3.org 模式使用静态缓存。看到这个答案：stackoverflow.com/a/8562410/3571

【解决方案1】：

我也遇到过这个问题。但是，我只是间歇性地收到此错误。我发现另一个帖子提到了一个可能的解决方案，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这个问题。

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。这个让我快疯了。

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，但我需要设置我的脚本以在本地下载 messages.xsd、types.xsd 和 services.wsdl 并对其进行修补。带有以下内容：

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

希望这将为您指明正确的方向。简单地用 suds 与 Exchange 交谈是一项重大挑战。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>

为简洁起见，我已经截断了 xml。

【讨论】：

我找到了用于我的项目的 demo.py 和 Exchange.py 脚本的链接。 [链接]web.archiveorange.com/archive/v/QOiOM0hVaQTkgK3oowG6
我发现了为什么会这样。看起来当 suds 客户端初始化时，它会从 w3.org/2001/xml.xsd 下载架构定义。由于需要从 w3.org 获取模式文件的 Web 应用程序增加，服务器超时并返回空响应。已建议在本地缓存模式定义。希望这可以帮助。 lists.w3.org/Archives/Public/site-comments/2011Apr/0026.html
非常感谢，非常感谢您提供的所有信息。这几天我一直在为此苦苦挣扎。感谢您的代码，但我已经在使用它了。我是从您为 demo.py 和 Exchange.py 建议的相同链接获得的。问题是我总是收到 BadStatusLine，对我来说一次都没用。
脚本失败前有延迟吗？
是的，有大约 35 秒的延迟。
