SUDS:在Client.service方法中传递数组参数: GAE

Question

在我的一个应用程序中，正在使用GAE上的苏打 WSDL(SOAP) web服务。

我的Py代码

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

因此，它在服务器控制台上打印。

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

实际上可以传递字符串、赎回方法中的双类型值，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')

但是我无法在这里传递VoucherReqDtls数组

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>

因此，我如何在VoucherReqDtls赎回方法中传递数组/列表，这里的VoucherType是GV，VoucherNo的计数可能不止一个。

Answer 1

我认为问题在于，如果您直观地检查WSDL，则code方法需要使用以下代码创建的复杂类型的GatwayReq：

>>> 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
            }
      }
 }

可以将元素添加到GatewayReq对象中，就像添加anyt对象属性一样，即

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

然后，您将调用如下所示的赎回方法：

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

编辑

可以使用以下语法创建所需的类型：

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

这使用此机制访问此处指定的任何顶级类型( 肥皂药房-工厂 )。

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
            }
      }
  }

这将创建xml，如下所示，其中包含所需的语法：

<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>

或者至少我认为它应该是这样的

希望它能帮上忙
