[英]Having problems with Python SOAP using Suds
我在使用Suds时遇到问题,无法弄清楚是什么使它表现得如此。 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会话并尝试解释发生了什么。 您看到的'request'变量的类型为ShippingGuideRequestType,并使用client.factory.create(“ ShippingGuideRequestType”)创建。
(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看起来不错,现在让我们尝试用数据填充必填字段。 首先让我们处理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,它是用更复杂的方式创建的。 首先,我创建PackagesInputType,然后创建一个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
(Pdb) request.ProductIds = productsInput
(Pdb) request.Packages = packagesInput
(Pdb) request
(ShippingGuideRequestType){
UserInformation =
(UserInformationType){
Usercode = "-CENCORED"
}
RequestProperties =
(RequestPropertiesType){
SchemaVersion = None
Language = None
WithPrice = None
WithExpectedDelivery = None
WithGuiInformation = None
NumberOfAlternativeDeliveryDates = None
EDI = None
PostingAtPostoffice = None
Trace = None
}
ProductIds =
(ProductIdsType){
ProductId[] =
"SERVICEPAKKE",
}
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[] =
(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"
},
}
}
在我看来,该结构看起来不错,现在让我们尝试调用该服务。
(Pdb) self.client.service.ShippingGuide(request)

*** WebFault: Server raised fault: 'FG_INPUT_003 User information missing from request. [errorId cf19f72b-0795-4f58-8a70-a8c1846ba186]'
这里发生了什么? 为什么所有内容都编码在UserInformation元素内?
你有没有尝试一下:
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)
