我在使用 Suds 时遇到问题，我不知道是什么让它表现得像这样。我正在尝试调用 Web 服务，并且该服务将一种复杂类型作为参数（ShippingGuideRequestType）。我将发布我的 pdb 会话并尝试解释正在发生的事情。您看到的“请求”变量是 ShippingGuideRequestType 类型，它是使用 client.factory.create("ShippingGuideRequestType") 创建的。

(Pdb) request
(ShippingGuideRequestType){
   UserInformation = 
      (UserInformationType){
         Usercode = None
      }
   RequestProperties = 
      (RequestPropertiesType){
         SchemaVersion = None
         Language = None
         WithPrice = None
         WithExpectedDelivery = None
         WithGuiInformation = None
         NumberOfAlternativeDeliveryDates = None
         EDI = None
         PostingAtPostoffice = None
         Trace = None
      }
   ProductIds = 
      (ProductIdsType){
         ProductId[] = <empty>
      }
   Consignment = 
      (ConsignmentInputType){
         FromCountryCode = None
         FromPostalCode = None
         ToCountryCode = None
         ToPostalCode = None
         ShippingDate = 
            (DateAndTimeType){
               Year = None
               Month = None
               Day = None
               Hour = None
               Minute = None
            }
         EarlyCollectionAtTerminal = None
         AdditionalServices = 
            (AdditionalServicesInputType){
               AdditionalService[] = <empty>
            }
      }
   Packages = 
      (PackagesInputType){
         Package[] = <empty>
      }
 }

ShippingGuideRequestType 看起来不错，现在让我们尝试用数据填充必填字段。让我们首先处理 UserInformation 属性。这是使用 client.factory.create("UserInformationType") 创建的：

(Pdb) userInformation
(UserInformationType){
   Usercode = "-CENCORED-"
 }

现在让我们处理使用 client.factory.create("ProductIdsType") 创建的 ProductIds：

(Pdb) productsInput
(ProductIdsType){
   ProductId[] = 
      "SERVICEPAKKE",
 }

最后一个必需的属性是 PackagesInputType，它是以更复杂的方式创建的。首先创建 PackagesInputType，然后创建 PackageInputType 数组（使用 client.factory.create("PackageInputType")）。

(Pdb) packagesInput
(PackagesInputType){
   Package[] = 
      (PackageInputType){
         Height = 
            (UnitCodeLengthType){
               value = 10
               _unitCode = "CMT"
            }
         Width = 
            (UnitCodeLengthType){
               value = 10
               _unitCode = "CMT"
            }
         Length = 
            (UnitCodeLengthType){
               value = 10
               _unitCode = "CMT"
            }
         GrossWeight = 
            (UnitCodeWeightType){
               value = 1000
               _unitCode = "GRM"
            }
         Volume = 
            (UnitCodeCubicType){
               value = None
               _unitCode = "DMQ"
            }
         VolumeSpecial = None
         FromCountryCode = None
         FromPostalCode = "7800"
         ToCountryCode = None
         ToPostalCode = "7041"
         ShippingDate = 
            (DateAndTimeType){
               Year = None
               Month = None
               Day = None
               Hour = None
               Minute = None
            }
         AdditionalServices = 
            (AdditionalServicesInputType){
               AdditionalService[] = <empty>
            }
         EarlyCollectionAtTerminal = None
         _packageId = "myRef"
      },
 }
(Pdb) request.UserInformation = userInformation

               GrossWeight =

                     _unitCode = "GRM"
                  }
               Volume =

               AdditionalServices =

               EarlyCollectionAtTerminal = None
               _packageId = "myRef"
            },
      }
 }

在我看来，结构看起来不错，现在让我们尝试调用服务。

这里发生了什么？为什么所有内容都在 UserInformation 元素中编码？

你试一试：

shipping = client.factory.create("ShippingGuideRequestType")

shipping.UserInformation.UserCode = val1

shipping.RequestProperties.SchemaVersion = val2
shipping.RequestProperties.Language = val3

//Add the rest of the values.

client.service.shippingFunction(shipping)
