使用RestSharp客户端反序列化嵌套的JSON

Question

我想使用REST-Api并反序列化嵌套的JSON响应。我使用json2csharp.com.创建了这些类

JSON以消费

{
id: 32,
name: "test supply object",
formId: 4,
sortOrder: 0,
created: 1572902163907,
creator: "jsingler",
attributes: [
{
id: 144,
attribute: {
attributeName: "Description",
attributeType: "TextArea",
id: 8
},
attributeValue: "for development testing. do not delete or use."
},
{
id: 145,
attribute: {
attributeName: "Quantity",
attributeType: "NumberLong",
id: 10
},
attributeValue: "4"
}
]
}

JSON2CSHARP.COM输出

public partial class Asset
{
[JsonProperty(PropertyName = "id")]
public int id { get; set; }
[JsonProperty(PropertyName = "name")]
public string name { get; set; }
[JsonProperty(PropertyName = "formId")]
public int formId { get; set; }
[JsonProperty(PropertyName = "sortOrder")]
public int sortOrder { get; set; }
[JsonProperty(PropertyName = "created")]
public long created { get; set; }
[JsonProperty(PropertyName = "creator")]
public string creator { get; set; }
public List<Attribute> attributes { get; set; }
}
public partial class Attribute
{
[JsonProperty(PropertyName = "ida")]
public int id { get; set; }
[JsonProperty(PropertyName = "attribute")]
public List<Attribute1> attribute { get; set; }
[JsonProperty(PropertyName = "attributeValue")]
public string attributeValue { get; set; }
}
public partial class Attribute1
{
[JsonProperty(PropertyName = "attributeName")]
public string attributeName { get; set; }
[JsonProperty(PropertyName = "attributeType")]
public string attributeType { get; set; }
[JsonProperty(PropertyName = "ida1")]
public int id { get; set; }
}

消耗API数据的方法

public static List<Asset> GetAllAssets()
{
var client = new RestClient("URL_USED");
var request = new RestRequest();
client.Authenticator = new HttpBasicAuthenticator("USERNAME", "PW");
var response = new RestResponse();
Task.Run(async () =>
{
response = await GetResponseContentAsync(client, request) as RestResponse;
}).Wait();
var AssetList = JsonConvert.DeserializeObject<List<Asset>>(response.Content);
return AssetList;
}

这总是错误： An unhandled exception occurred while processing the request. JsonSerializationException: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[PVF_Web.Models.Attribute1]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path '[0].attributes[0].attribute.attributeName', line 1, position 158.

然后，当我能够让JSON进行反序列化时，它不会返回属性(应用程序的真正用途(。

任何建议或想法都将不胜感激。

编辑1

[HttpPut]
public void Send(Asset newJA, int Qty)
{
var client = new RestClient("URL_TO_USE" + newJA.id + ".json");
var request = new RestRequest("", Method.PUT);
request.AddObject(newJA);
client.Authenticator = new HttpBasicAuthenticator("USERNAME", "PW");
client.ExecuteAsync(request, response => {
Console.WriteLine(response.Content);
Debug.WriteLine(response.Content);
});
}

这总是失败的。

Answer 1

您的JSON无效。转到https://jsonformatter.curiousconcept.com/并检查所有错误。

属性名称必须在引号之间，如果您希望它是一个数组，则需要将其作为一个数组——在json的开头和结尾添加方括号-[]。

Answer 2

首先要确保您的json是有效的。你可以看看这边json属性必须在引号内"像这个

"id">

。

除此之外，您的根对象不是列表。因此，您必须将反序列化代码更改为：

var AssetList = JsonConvert.DeserializeObject<Asset>(response.Content);
