SUDS生成的XML不正确

Question

我正在尝试使用SUDS和Python与SOAP Web服务进行通信.经过大量学习Python的麻烦(是的,我是新手),并研究如何使用SUDS,我遇到了一个问题.

根据肥皂泡沫,我呼吁的网络方法的签名是

(FWTCaseCreate){
ClassificationEventCode = None
Priority = None
Title = None
Description = None
Queue = None
DueDate = None
AssociatedObject = 
  (FWTObjectBriefDetails){
     ObjectID = 
        (FWTObjectID){
           ObjectType = None
           ObjectReference[] = <empty>
        }
     ObjectDescription = None
     Details = None
     Category = None
  }
Form = 
  (FWTCaseForm){
     FormField[] = <empty>
     FormName = None
     FormKey = None
  }
Internal = None
InteractionID = None
XCoord = None
YCoord = None
}

所以我使用SUDS创建我想要的类并将其发送到方法.但是我收到了一个错误.所以我开启登录,我可以看到正在发送的XML不正确,导致反序列化错误.SOAP包如下所示

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://www.CRM.com/wsdl/FLTypes"    xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
   <wsse:Security>
      <wsse:BinarySecurityToken>eaadf1ddff99a8</wsse:BinarySecurityToken>
   </wsse:Security>
</SOAP-ENV:Header>
<ns1:Body>
   <ns0:FWTCaseCreate>
      <ClassificationEventCode>
         <ClassificationEventCode>2000023</ClassificationEventCode>
         <Priority>1</Priority>
         <Title>testing</Title>
         <Description>testing</Description>
         <Queue/>
         <Internal>True</Internal>
         <XCoord>356570</XCoord>
         <YCoord>168708</YCoord>
      </ClassificationEventCode>
   </ns0:FWTCaseCreate>
</ns1:Body>

正如您所看到的,所有其他元素周围都有一个"ClassificationEventCode"元素,这不应该存在.如果我将此xml剪切并粘贴到SOAPUI中,并首先删除此元素,然后将其直接发布到Web服务,它就能成功运行.

这是我用来拨打电话的代码

client = Client(url)

#Add a header for the security
ssnns = ('wsse', 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd')

ssn = Element('BinarySecurityToken', ns=ssnns).setText(binaryKey)

ssn1 = Element('Security',ns=ssnns)

ssn1.append(ssn)

client.set_options(soapheaders=ssn1) 

newCase = client.factory.create('ns1:FWTCaseCreate')

classEventCode = client.factory.create('ns1:FWTEventCode')
classEventCode.value = 2000023

newCase.ClassificationEventCode = classEventCode
newCase.Priority = 1
#optional
newCase.AssociatedObject = None
#optional
newCase.Form = None
#optional
newCase.Internal = None
#optional
newCase.InteractionID =  None
#optional
newCase.DueDate = None
#optional
newCase.Queue = None

newCase.Title = 'Title'

newCase.Description = 'description'

newCase.XCoord = '356570'

newCase.YCoord = '168708'

caseID = client.service.createCase(newCase)

有没有人有任何想法为什么会这样？我猜SUDS认为它应该基于WSDL.

谢谢.

我是恰好有同样的问题.我的SOAP请求中的参数序列被包装在一个与第一个参数同名的元素中.例如

....
   <ns0:Body>
      <ns1:CreationReq>
         <ReqType>
            <ReqType>1</ReqType>
            <Title>Mr</Title>
            ....
         </ReqType>
      </ns1:CreationReq>
   </ns0:Body>
....

我检查了WSDL,以确保它没有问题.

看起来问题是因为我使用client.factory.create方法创建了一个CreationReq对象.通过打印检查客户端显示我正在调用的方法不将该对象作为参数.而是需要一个名为args的列表.

所以我的代码是:

req = client.factory.create('CreationReq')
req.ReqType = 1
req.Title = 'Mr'
resp = client.service.Create(req)

现在它是:

req = {}
req['ReqType'] = 1
req['Title'] = 'Mr'
resp = client.service.Create(**req)
