如何用pysimplesoap构造SOAP消息？

我试图用PySimpleSoap调用荷兰政府土地注册处（WSDL here）的SOAP服务。到目前为止，我这样做是为了连接：

from pysimplesoap.client import SoapClient
client = SoapClient(wsdl='http://www1.kadaster.nl/1/schemas/kik-inzage/20141101/verzoekTotInformatie-2.1.wsdl')

在an awesome answer by Plamen Petrov的帮助下，我现在明白需要使用client.VerzoekTotInformatie()方法发送下面的xml。

然而，我不明白的是，如何获得所需的XML（见下文）。我当然可以手动构建它，但我感觉有一种更聪明/更像Python的方法来构建它。我可以使用pysimplesoap来构造这个消息xml吗？

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="http://www.kadaster.nl/schemas/kik-inzage/20141101" xmlns:v20="http://www.kadaster.nl/schemas/kik-inzage/ip-aanvraag/v20141101">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:VerzoekTotInformatieRequest>
         <v20:Aanvraag>
            <v20:berichtversie>?</v20:berichtversie>
            <v20:klantReferentie>ABC</v20:klantReferentie>
            <v20:productAanduiding>?</v20:productAanduiding>
            <v20:Ingang>
               <v20:Object>
                  <v20:IMKAD_KadastraleAanduiding>
                     <v20:gemeente>Amsterdam</v20:gemeente>
                     <v20:sectie>123</v20:sectie>
                     <v20:perceelnummer>456</v20:perceelnummer>
                     <v20:appartementsindex>789</v20:appartementsindex>
                     <v20:deelperceelnummer>10</v20:deelperceelnummer>
                     <v20:AKRKadastraleGemeenteCode>20</v20:AKRKadastraleGemeenteCode>
                  </v20:IMKAD_KadastraleAanduiding>
               </v20:Object>
            </v20:Ingang>
         </v20:Aanvraag>
      </ns:VerzoekTotInformatieRequest>
   </soapenv:Body>
</soapenv:Envelope>

按照the docs中的示例，我现在尝试添加带有berichtversie的VerzoekTotInformatieRequest，然后尝试对soap服务执行请求。但是正如你在下面看到的，身体仍然只有一个空的<VerzoekTotInformatie>（没有Request），另外我得到了一个巨大的错误。有什么想法我可以建立以上的信息？

>>> client['VerzoekTotInformatieRequest'] = {'Aanvraag': {'berichtversie': 'yay'}}
>>> c.VerzoekTotInformatie()

构造xml不是调用soap方法的必要（或正确）方法。PySimpleSoap已经提供了一种非常优雅和可读的方法来实现这一点：

client = SoapClient(wsdl='http://www1.kadaster.nl/1/schemas/kik-inzage/20141101/verzoekTotInformatie-2.1.wsdl', trace=True)
client.VerzoekTotInformatie(Aanvraag={'berichtversie':4.7, 
                                      'klantReferentie':'cum murmure', 
                                      'productAanduiding': 'aeoliam venit'})

调试日志如下：

                </Aanvraag>
            </VerzoekTotInformatieRequest>
        </soap:Body>
</soap:Envelope>

如您所见，xml是自动构造并发送到服务器的。但是我得到了401: Unauthorized错误，您可能知道如何修复。
