无效的 SUDS 信封

Question

当我尝试执行这段代码时：

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')

以下信封已创建：

<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>

但是如果我在soapUI中把它改成

<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>

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 body 标签创建为 <SOAP-ENV:Body> 而不是 <ns1:Body> 还是

我尝试了这个，看看我是否可以更改通过网络发送的 XML，并使用 wireshark 来嗅探流量，结果发现它并没有改变正在发送的消息。由于我在控制台中看到了打印输出，因此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

我将 EnvelopeFixer 更改为使用 marshalled 而不是发送，这似乎成功了

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

所以现在我更改了 body 元素的前缀以符合服务器的要求。快乐！

很遗憾，RPC 端点没有正确解析 XML。一种解决方法是向您的Client() 添加一个插件，在发送前编辑信封。 MessagePlugin 让您有机会在发送前修改 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()])
