Question

当我尝试执行此代码时：

mmurl = 'http://server/_mmwebext/mmwebext.dll?WSDL?server=localhost'
mmclient = Client(mmurl, plugins=[EnvelopeFixer()])
loginResult = mmclient.service[1].Login(u'localhost', u'user', u'pass')

创建以下信封：

<SOAP-ENV:Envelope xmlns:ns0="http://menandmice.com/webservices/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <ns1:Body>
      <ns0:Login>
         <ns0:server>localhost</ns0:server>
         <ns0:loginName>user</ns0:loginName>
         <ns0:password>pass</ns0:password>
      </ns0:Login>
   </ns1:Body>
</SOAP-ENV:Envelope>

返回：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Invalid command.</faultstring>
         <detail>
            <mmfaultdetails>
               <message>Invalid command.</message>
               <errorcode>5001</errorcode>
            </mmfaultdetails>
         </detail>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

但如果我在soapUI中将其更改为

<SOAP-ENV:Envelope xmlns:ns0="http://menandmice.com/webservices/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <ns0:Login>
         <ns0:server>localhost</ns0:server>
         <ns0:loginName>user</ns0:loginName>
         <ns0:password>pass</ns0:password>
      </ns0:Login>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

它成功返回

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <SOAP-ENV:Body>
      <LoginResponse xmlns="http://menandmice.com/webservices/">
         <session>UEk6A0UC5bRJ92MqeLiU</session>
      </LoginResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

所以我的问题是，我可以强制suds将身体标记创建为<SOAP-ENV:Body>而不是<ns1:Body>或

我试过这个，看看我是否可以更改通过线路发送的XML并使用wireshark来嗅探流量，结果发现它没有改变发送的消息。因为我在控制台中看到了打印输出，所以肯定会调用发送方法

class EnvelopeFixer(MessagePlugin):
    def sending(self, context):
        # context is the envelope text
        print type(context)
        context.envelope = context.envelope.upper()
        print context.envelope

        return context

我改变了EnvelopeFixer使用marshalled而不是发送，这似乎已经完成了这个技巧

class EnvelopeFixer(MessagePlugin):

    def marshalled(self, context):
        root = context.envelope.getRoot()
        envelope = root.getChild("Envelope")
        envelope.getChildren()[1].setPrefix("SOAP-ENV")
        print envelope.getChildren()[1]

        return context

所以现在我已经更改了body元素的前缀以符合服务器的要求。 JOY！

令人遗憾的是，RPC端点无法正确解析XML。一种解决方法是在发送前编辑信封的Client()添加一个插件。 MessagePlugin使您有机会在发送之前修改suds.sax.document.Document或消息文本。

from suds.plugin import MessagePlugin
class EnvelopeFixer(MessagePlugin):
    def sending(self, context):
        # context is the envelope text
        context.envelope = context.envelope.upper()
        return context

client = Client(..., plugins=[EnvelopeFixer()])

无效的SUDS信封
