使用 Suds 使用 Python SOAP 时遇到问题

我在使用肥皂水时遇到了问题，我不明白是什么导致了它的行为如此。 我正在尝试调用一个 Web 服务，该服务采用一种复杂类型作为 参数（ShippingGuideRequestType）。我将发布我的 pdb 会话并尝试解释什么 正在发生。您看到的“请求”变量的类型为 ShippingGuideRequestType 并且 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，现在让我们尝试填充所需的 带有数据的字段。我们首先处理 UserInformation 属性。这是 使用 client.factory.create("UserInformationType") 创建：

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

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

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

最后一个必需的属性是 PackagesInputType，这是稍后创建的 更复杂的方式。首先，我创建 PackagesInputType，然后创建一个数组 PackageInputType（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"

            }
         AdditionalServices =

            }
         EarlyCollectionAtTerminal = None
         _packageId = "myRef"
      },
 }
(Pdb) request.UserInformation = userInformation

                  }
               GrossWeight = 
                  (UnitCodeWeightType){
                     value = 1000
                     _unitCode = "GRM"
                  }
               Volume = 
                  (UnitCodeCubicType){

               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"
            },
      }
 }

在我看来，结构看起来不错，现在让我们尝试调用该服务。

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

原文

I'm having problems with Suds and I can't figure out what makes it behave like this.
I'm trying to call a webservice and that service takes one complex type as an
argument (ShippingGuideRequestType). I'll post my pdb session and try to explain what
is happening. The 'request' variable you see is of type ShippingGuideRequestType and
it is created using client.factory.create("ShippingGuideRequestType").

(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>
      }
 }

The ShippingGuideRequestType looks OK, now let's try to populate the required
fields with data. Let's first deal with the UserInformation property. This is
created using client.factory.create("UserInformationType"):

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

Now let's handle the ProductIds which is created using
client.factory.create("ProductIdsType"):

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

The final required property is the PackagesInputType, this is created in a bit
more complex manner. First I create the PackagesInputType, then I create an array
of PackageInputType (using 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"
      },
 }

               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"
            },
      }
 }

In my point of view the structure looks fine, now let's try to call the service.

*** WebFault: Server raised fault: 'FG_INPUT_003 User information missing from request. [errorId cf19f72b-0795-4f58-8a70-a8c1846ba186]'

What happened here? Why is everything encoded within the UserInformation element?

你有没有尝试过：

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)

Have you give this a go:

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)
