NewtonSoft JSON不解析数组中的引用项

时间：2018-04-11 18:01:18

标签： json json.net

我编写的Web API除了带有引用的JSON之外，我使用JsonPropertyAttribute和JsonObjectAttribute来标记可以被其他属性引用的属性/类。 当我从API接收数据时，它按预期工作，在JSON中设置了相应的$id和$ref属性。但是，当我向API发布相同的JSON日期时，它不会解析所有数据。 Bellow是我从API收到的数据，我也回复了。

{
  "GeneralDetails": {
    "Description": "23",
    "ScheduleInfo": {
        "ScheduleFrequency": 701,
        "ScheduledDay": null,
        "ScheduledMonth": null,
        "ScheduledTime": "2018-04-10T21:30:01"
    },
    "ImagePath": "",
    "BrandId": 23,
    "Name": "23",
    "Id": 29
},
"TargetDetails": {
    "Period": 0,
    "Type": 2701,
    "Targets": [
        {
            "TierId": 34,
            "Value": 29
        }
    ]
},
"PointsDetails": [
    {
        "BooleanExperession": {
            "$id": "1",
            "$type": "Payback.TradeTool.Entities.Model.Offer.OfferRuleBooleanExpression, Payback.TradeTool.Entities",
            "Variable1": {
                "$id": "2",
                "$type": "Payback.TradeTool.Entities.Model.Offer.OfferRulePreDefinedVariable, Payback.TradeTool.Entities",
                "GroupId": 2,
                "Type": 12,
                "AvailableOperant": 289,
                "Description": "Product SKU",
                "Name": "Product SKU",
                "Id": 67
            },
            "Variable2": {
                "$id": "3",
                "$type": "Payback.TradeTool.Entities.Model.Offer.OfferRuleConstant`1[[System.String, mscorlib]], Payback.TradeTool.Entities",
                "Value": "23",
                "Type": 9,
                "AvailableOperant": 289,
                "Description": "2323",
                "Name": "2323",
                "Id": 132
            },
            "Operation": 1,
            "Type": 130,
            "AvailableOperant": 0,
            "Description": "23",
            "Name": "23",
            "Id": 133
        },
        "Value": 23,
        "Id": 16,
        "Type": 0,
        "ValueX": null
    }
],
"Constants": [
    {
        "$id": "4",
        "Value": "rty",
        "Type": 9,
        "AvailableOperant": 289,
        "Description": "rty",
        "Name": "yurt",
        "Id": 130
    },
    {
        "$id": "5",
        "Value": 23,
        "Type": 17,
        "AvailableOperant": 231,
        "Description": "23",
        "Name": "ewe",
        "Id": 131
    },
    {
        "$ref": "3"
    }
],
"BooleanExpressions": [
    {
        "$ref": "1"
    }
],
}

当我使用Constants $id发回4时，5不在解析数据中。但是，如果我在其他属性中引用它们，那么它们也在解析。

修改 下面是我的班级结构

public class OfferDetails
{
    public OfferDetails()
    {
        GeneralDetails = new OfferGeneralDetails();
        TargetDetails = new OfferTargetDetails();
        PointsDetails = new List<OfferPointsDetails>();
        Constants = new List<OfferRuleConstant>();
        BooleanExpressions = new List<OfferRuleBooleanExpression>();
        Variables = new Dictionary<string, List<OfferRulePreDefinedVariable>>();
    }
    public OfferGeneralDetails GeneralDetails { get; set; }
    public OfferTargetDetails TargetDetails { get; set; }
    [JsonProperty(ItemTypeNameHandling = TypeNameHandling.All)]
    public List<OfferPointsDetails> PointsDetails { get; set; }
    [JsonProperty(IsReference = false, ItemTypeNameHandling = TypeNameHandling.All)]
    public List<OfferRuleConstant> Constants { get; set; }
    [JsonProperty(ItemTypeNameHandling = TypeNameHandling.All,IsReference = false)]
    public List<OfferRuleBooleanExpression> BooleanExpressions { get; set; }
    public Dictionary<string, List<OfferRulePreDefinedVariable>> Variables { get; set; }
}


[JsonObject(ItemTypeNameHandling = TypeNameHandling.All, IsReference = true)]
public class OfferRuleConstant<T> : OfferRuleConstant
{
    public OfferRuleConstant()
    {
        Type = RuleVariableType.Constant;
    }
    public T Value {  get => (T)_value; set=> _value = value;}
    public override string ToString()
    {
        return Value.ToString();
    }
}
public abstract class OfferRuleConstant : OfferRuleVariable, ISeprateStringReprsentation
{
    protected object _value;

    public string StringReprsentation { get ; set ; }
}

[JsonObject(IsReference = true, ItemTypeNameHandling = TypeNameHandling.All)]
public class OfferRuleVariable : NamedEntity<long>
{
    public OfferRuleVariable()
    {
        Type = RuleVariableType.Variable;
    }
    public RuleVariableType Type { get; set; }
    public RuleOperantEnum AvailableOperant { get; set; }
    public string Description { get; set; }
    // public int GroupId { get; set; }
}
[JsonObject(IsReference = true, ItemTypeNameHandling = TypeNameHandling.All)]
public class OfferRulePreDefinedVariable : OfferRuleVariable
{
    public int GroupId { get; set; }
}
public interface ISeprateStringReprsentation 
{
    string StringReprsentation { get; set; }
}

我可能在模型中做了一些更改（在几个类中添加了一个新属性，并且在尝试修复上述问题时也更改了一些属性）。

所以，这是我正在尝试解析的更新JSON：

大多数常量都在解析，但对应于"$id":17不在列表中。

1 个答案:

答案 0 :(得分：0)

经过几次尝试，我找到了我的错误，在json中是"$id"属性。这是数字，但是从API生成的原始JSON中，它是数字。

所以，我改变了生成JSON的javaScript代码并且它有效。但是我无法理解它失败的原因。当我最初使用与生成的表单API相同的数据发布时。可能我只是感到困惑。
