使用Suds的Python SOAP遇到問題

Question

我在使用Suds時遇到問題，無法弄清楚是什么使它表現得如此。 我正在嘗試調用Web服務，並且該服務將一種復雜類型作為參數（ShippingGuideRequestType）。 我將發布我的pdb會話並嘗試解釋發生了什么。 您看到的'request'變量的類型為ShippingGuideRequestType，並使用client.factory.create（“ ShippingGuideRequestType”）創建。

(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看起來不錯，現在讓我們嘗試用數據填充必填字段。 首先讓我們處理UserInformation屬性。 這是使用client.factory.create（“ UserInformationType”）創建的：

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

現在，讓我們處理使用client.factory.create（“ ProductIdsType”）創建的ProductIds：

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

最后一個必需的屬性是PackagesInputType，它是用更復雜的方式創建的。 首先，我創建PackagesInputType，然后創建一個PackageInputType數組（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
(Pdb) request.ProductIds = productsInput
(Pdb) request.Packages = packagesInput
(Pdb) request
(ShippingGuideRequestType){
   UserInformation = 
      (UserInformationType){
         Usercode = "-CENCORED"
      }
   RequestProperties =

         WithGuiInformation = None
         NumberOfAlternativeDeliveryDates = None
         EDI = None
         PostingAtPostoffice = None
         Trace = None
      }

      (ProductIdsType){
         ProductId[] =

      }

      (ConsignmentInputType){
         FromCountryCode = None
         FromPostalCode = None
         ToCountryCode = None
         ToPostalCode = None
         ShippingDate = 
            (DateAndTimeType){
               Year = None

               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"
            },
      }
 }

在我看來，該結構看起來不錯，現在讓我們嘗試調用該服務。

這里發生了什么？ 為什么所有內容都編碼在UserInformation元素內？

Answer 1

你有沒有嘗試一下：

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)
