你好。
我在生成 Json 时出错。 错误是“ValueAddedService”类型的值无法转换为 System.Collections.Generic.List(Of ValueAddedService)’
另外,日期和时间是“messageDateTime =”\/Date(1674459281468)\/”,不是像“2023-01-19T11:20:27+08:00”这样的日期时间格式
请就上述两个问题给我建议
谢谢
马丁
我尝试过的:
VB
Dim root As List(Of Root) = New List(Of Root)() Dim PickupAddress As PickupAddress = New PickupAddress With { .name = "xxy Company LTD", .address1 = "1, 11,13, Jalan Rajawali", .address2 = "Bandar Puchong Jaya", .city = "Puchong", .country = "MY", .district = "Puchong", .state = "Selangor", .postCode ="47000", .email = "sales@xxy.com", .phone = "069076 1651" } Dim shipperAddress As ShipperAddress = New ShipperAddress With { .name = "xxy Company LTD", .address1 = "1, 11,13, Jalan Rajawali", .address2 = "Bandar Puchong Jaya", .city = "Puchong", .country = "MY", .district = "Puchong", .state = "Selangor", .postCode ="47000", .email = "sales@xxy.com", .phone = "069076 1651" } Dim consignement As ConsigneeAddress = New ConsigneeAddress With { .name = "Poliklinik Gunwant", .address1 = "Lot 9797, Jalan Menteri", .address2 = "Sungai Besar Selangor", .city = "Sungai Besar", .state = "Selangor", .district = "Sungai Besar", .country = "MY", .postCode = "46000", .email = "", .phone = "092548 3257" } Dim valADDService As ValueAddedService = New ValueAddedService With { .vasCode = "PPOD"} Dim valueAddedServices As List(Of ValueAddedServices) = New List(Of ValueAddedServices)() valueAddedServices.Add(New ValueAddedServices With {.valueAddedService = valADDService}) Dim shipmentPieces As List(Of ShipmentPiece) = New List(Of ShipmentPiece)() shipmentPieces.Add(New ShipmentPiece With { .pieceID = "1"}) Dim shipItem As List(Of ShipmentItem) = New List(Of ShipmentItem)() shipItem.Add(New ShipmentItem With { .consigneeAddress = consignement, .shipmentID = "123456789", .packageDesc = "abc", .totalWeight = "1", .totalWeightUOM = "KG", .dimensionUOM = "CM", .productCode = "PDO", .currency = "USD", .remarks = "", .isMult = "true", .deliveryOption = "C", .shipmentPieces = shipmentPieces }) Dim hdr As Hdr = New Hdr With { .accessToken ="123456789", .messageDateTime ="\/Date(1674459281468)\/", .messageLanguage = "en", .messageType = "SHIPMENT", .messageVersion = "1.4" } Dim bd As Bd = New Bd With { .pickupAccountId = "123587", .soldToAccountId = "325784", .pickupDateTime = "\/Date(1674459281468)\/", .handoverMethod = "1", .pickupAddress = PickupAddress, .shipperAddress = shipperAddress, .shipmentItems = shipItem } Dim manifesto As ManifestRequest = New ManifestRequest With { .bd = bd, .hdr = hdr } root.Add(New Root With { .manifestRequest = manifesto }) Dim serializer As JavaScriptSerializer = New JavaScriptSerializer() v_jsonData = "" v_jsonData = serializer.Serialize(root) Me.txtJsonData.Text = serializer.Serialize(root)
结果应该如下。
{ "manifestRequest": { "hdr": { "messageType": "SHIPMENT", "messageDateTime": "2023-01-19T11:20:27+08:00", "accessToken": "f0108fb771fa4d269e10d8702f487b93", "messageVersion": "1.4", "messageLanguage": "en" }, "bd": { "pickupAccountId": "5264574522", "soldToAccountId": "5264574522", "pickupDateTime": "2023-01-19T11:20:27+08:00", "handoverMethod": 1, "pickupAddress": { "name": "Jet Pharam", "address1": "adddress1", "address2": "address2 .", "city": "puchong", "state": "selangor", "district": "puchong", "country": "MY", "postCode": "46000", "phone": "123456789", "email": "abc@jetpharma.com" }, "shipperAddress": { "name": "Jet Pharam", "address1": "Address1", "address2": "Address2", "city": "Puchong", "state": "Selangor", "district": "Puchong", "country": "MY", "postCode": "46000", "phone": "123456789", "email": "abc@jetpharma.com" }, "shipmentItems": [ { "consigneeAddress": { "name": "Poliklinik Gunwant", "address1": "Lot 9797, Jalan Menteri", "address2": "Lot 9797, Jalan Menteri", "city": "Sungai Besar", "state": "Selangor", "district": "Sungai Besar", "country": "MY", "postCode": "45300", "phone": "123456789", "email": "abc@xxx.com" }, "shipmentID": "MYJMS346524660", "packageDesc": "asdasad", "totalWeight": 1, "totalWeightUOM": "G", "dimensionUOM": "CM", "productCode": "PDO", "currency": "MYR", "remarks": "JETPharma", "isMult": "true", "valueAddedServices": { "valueAddedService": [ { "vasCode": "PPOD" } ] }, "deliveryOption": "C", "shipmentPieces": [ { "pieceID": 11 } ] } ] } } }
解决方案1
通过 JSON 类转换器运行您的代码,它将生成以下结构:
Public Class Bd Public Property pickupAccountId As String Public Property soldToAccountId As String Public Property pickupDateTime As DateTime Public Property handoverMethod As Integer Public Property pickupAddress As PickupAddress Public Property shipperAddress As ShipperAddress Public Property shipmentItems As List(Of ShipmentItem) End Class Public Class ConsigneeAddress Public Property name As String Public Property address1 As String Public Property address2 As String Public Property city As String Public Property state As String Public Property district As String Public Property country As String Public Property postCode As String Public Property phone As String Public Property email As String End Class Public Class Hdr Public Property messageType As String Public Property messageDateTime As DateTime Public Property accessToken As String Public Property messageVersion As String Public Property messageLanguage As String End Class Public Class ManifestRequest Public Property hdr As Hdr Public Property bd As Bd End Class Public Class PickupAddress Public Property name As String Public Property address1 As String Public Property address2 As String Public Property city As String Public Property state As String Public Property district As String Public Property country As String Public Property postCode As String Public Property phone As String Public Property email As String End Class Public Class Root Public Property manifestRequest As ManifestRequest End Class Public Class ShipmentItem Public Property consigneeAddress As ConsigneeAddress Public Property shipmentID As String Public Property packageDesc As String Public Property totalWeight As Integer Public Property totalWeightUOM As String Public Property dimensionUOM As String Public Property productCode As String Public Property currency As String Public Property remarks As String Public Property isMult As String Public Property valueAddedServices As ValueAddedServices Public Property deliveryOption As String Public Property shipmentPieces As List(Of ShipmentPiece) End Class Public Class ShipmentPiece Public Property pieceID As Integer End Class Public Class ShipperAddress Public Property name As String Public Property address1 As String Public Property address2 As String Public Property city As String Public Property state As String Public Property district As String Public Property country As String Public Property postCode As String Public Property phone As String Public Property email As String End Class Public Class ValueAddedService Public Property vasCode As String End Class Public Class ValueAddedServices Public Property valueAddedService As List(Of ValueAddedService) End Class
因此,JSON 反序列化期望返回 Root 的实例,其中包含 ManifestRequest,而不是包含在子类中的集合。
当您反序列化 JSON 时,您将获得整个数据 – 而不仅仅是您可能感兴趣的部分!
解决方案3
您正在尝试反序列化 ValueAddedService 的单个实例并将其传递到 API 中。 如果您使用的是单个实例,那就没问题,但实际上您反序列化为一个列表,并将其发送到 API。
