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')
创建了以下信封:
<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>
但是如果我在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>
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>
或者是
我尝试这样做是为了看看是否可以更改通过线路发送的 XML,并使用wireshark 来嗅探流量,结果发现它并没有更改正在发送的消息。由于我在控制台中看到打印输出,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 更改为使用编码而不是发送,这似乎已经成功了
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
所以现在我已经更改了 body 元素的前缀以符合服务器的要求。快乐!
最佳答案
不幸的是,RPC 端点无法正确解析 XML。解决方法之一是向您的 Client()
添加一个插件,用于在发送之前编辑信封。一个MessagePlugin让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()])
