Question

在我的一个应用程序中，我在GAE python上使用SUDS WSDL（SOAP）Web服务。

我的 Py Code ：

url = 'http://203.215.51.43/Gateway/Execute?WSDL'
client = Client(url)
print client

所以它在服务器控制台

打印

Suds ( https://fedorahosted.org/suds/ )  version: 0.4 GA  build: R699-20100913
Service ( GatewayService ) tns="urn:fks:jcaps:gateway"
   Prefixes (2)
      ns0 = "http://fks.com/gtwy"
      ns1 = "urn:fks:jcaps:gateway:JavaException"
   Ports (1):
      (Execute)
         Methods (1):
            redeem(xs:string SessionId, xs:string TerminalId, xs:string StoreCod
e, xs:string CashMemoNo, xs:string CashMemoDate, xs:double InvoiceAmount, xs:str
ing TimeStamp, xs:string CashierId, xs:string MerchantId, ns0:SPCReqDtls SPCReqD
tls, ns0:VoucherReqDtls[] VoucherReqDtls, ns0:CardReqDtls CardReqDtls, )
         Types (1):
            ns1:JavaExceptionType

实际上我可以在兑换方法中传递字符串，双类型值，但不能传递数组/列表类型，

result = client.service.redeem(SessionId=result['SessionId'], StoreCode='4739', TerminalId='T1081', TimeStamp='01-01-2011 01:01:00.000')

但我无法通过 VoucherReqDtls 数组

此VoucherReqDtls的 WSDL的XML 代码如下所示，

    <!--Zero or more repetitions:-->
             <gtwy:VoucherReqDtls>
                <gtwy:VoucherType>GV</gtwy:VoucherType>
                <!--1 or more repetitions:-->
                <gtwy:VoucherReq>
                   <gtwy:VoucherNo>344234242</gtwy:VoucherNo>
                </gtwy:VoucherReq>
                <gtwy:VoucherReq>
                   <gtwy:VoucherNo>675685858</gtwy:VoucherNo>
                </gtwy:VoucherReq>
             </gtwy:VoucherReqDtls>

那么如何在兑换方法中传递 VoucherReqDtls 数组/列表，此处VoucherType为 GV 且计数为 VoucherNo < / strong>可能不止一个。

Answer 1

我认为问题在于，如果您直观地检查WSDL，则redeem方法需要一个复杂类型的GatwayReq，可以使用以下代码创建：

>>> it = client.factory.create('ns0:GatewayReq')
>>> it
(GatewayReq){
   SessionId = None
   TerminalId = None
   StoreCode = None
   CashMemoNo = None
   CashMemoDate = None
   InvoiceAmount = None
   TimeStamp = None
   CashierId = None
   MerchantId = None
   SPCReqDtls = 
      (SPCReqDtls){
         SPCNo = None
         SPCAmt = None
      }
   VoucherReqDtls[] = <empty>
   CardReqDtls = 
      (CardReqDtls){
         CardType = None
         CardReq = 
            (CardReq){
               CardNo = None
               TransAmt = None
            }
      }
 }

您可以像使用任何对象属性一样将元素添加到GatewayReq对象，即

>>> it.SessionId = 'blahablhabalh'
>>> it
(GatewayReq){
   SessionId = "blahablhabalh"
   # the rest removed for readability

然后你会像这样调用兑换方法：

>>>> client.service.redeem(it)

修改

您可以使用以下语法创建所需类型：

entry1 = client.factory.create('ns0:GatewayReq.ns0:VoucherReqDtls') >>> entry1 (VoucherReqDtls){ VoucherType = None VoucherReq[] = <empty> }

这使用该机制来访问此处suds docs - FACTORY
中指定的顶级类型
然后您可以将其添加到主请求对象中，如下所示：

>>> entry1.VoucherType = 'GV' >>> entry1.VoucherReq.append([12,34,56]) >>> entry1 (VoucherReqDtls){ VoucherType = "GV" VoucherReq[] = 12, 34, 56, } >>> entry1.VoucherReq.append(23) >>> entry1 (VoucherReqDtls){ VoucherType = "GV" VoucherReq[] = 12, 34, 56, 23, } >>> it.VoucherReqDtls.append(entry1) >>> it (GatewayReq){ SessionId = None TerminalId = None StoreCode = None CashMemoNo = None CashMemoDate = None InvoiceAmount = None TimeStamp = None CashierId = None MerchantId = None SPCReqDtls = (SPCReqDtls){ SPCNo = None SPCAmt = None } VoucherReqDtls[] = (VoucherReqDtls){ VoucherType = "GV" VoucherReq[] = 12, 34, 56, 23, }, CardReqDtls = (CardReqDtls){ CardType = None CardReq = (CardReq){ CardNo = None TransAmt = None } } }

这个创建xml如下所示，它可以算出所需的语法：

<SOAP-ENV:Header/> <ns0:Body> <ns1:GatewayReq> <ns1:SessionId> <ns1:SessionId/> <ns1:TerminalId/> <ns1:StoreCode/> <ns1:CashMemoNo/> <ns1:CashMemoDate/> <ns1:TimeStamp/> <ns1:CashierId/> <ns1:VoucherReqDtls> <ns1:VoucherType>GV</ns1:VoucherType> <ns1:VoucherReq>12</ns1:VoucherReq> <ns1:VoucherReq>34</ns1:VoucherReq> <ns1:VoucherReq>56</ns1:VoucherReq> <ns1:VoucherReq>23</ns1:VoucherReq> </ns1:VoucherReqDtls> <ns1:VoucherReqDtls> <ns1:VoucherType>GV</ns1:VoucherType> <ns1:VoucherReq>12</ns1:VoucherReq> <ns1:VoucherReq>34</ns1:VoucherReq> <ns1:VoucherReq>56</ns1:VoucherReq> <ns1:VoucherReq>23</ns1:VoucherReq> </ns1:VoucherReqDtls> </ns1:SessionId> <ns1:TerminalId/> <ns1:StoreCode/> <ns1:CashMemoNo/> <ns1:CashMemoDate/> <ns1:TimeStamp/> <ns1:CashierId/> </ns1:GatewayReq> </ns0:Body> </SOAP-ENV:Envelope>

或者至少我认为应该如何运作
