如何解析复杂的JSON结果

问题描述

我有一个JSON模型。但是我不确定要对结构进行建模。 所以ı通过https://json2csharp.com/创建了模型。

我想解析的Json structre：

   [
        {
            "id": 1,"dataTestId": "vuln-software-config-1","totalCpeCount": 1,"containers": [
                {
                    "operator": "OR","depth": 1,"dataTestId": "vuln-software-operator-1-0","configType": "BASIC","cpeListType": "VULNERABLE","cpes": [
                        {
                            "depth": 2,"vulnerable": true,"previous": false,"urlName": "cpe%3A2.3%3Aa%3Aapache%3Atomcat%3A*%3A*%3A*%3A*%3A*%3A*%3A*%3A*","cpe23Uri": "cpe:2.3:a:apache:tomcat:*:*:*:*:*:*:*:*","cpe22Uri": "cpe:/a:apache:tomcat","status": null,"resultingCpes": null,"dataTestId": "vuln-software-cpe-1-0-0","id": "4282632","matchCpes": [],"rangeDescription": " versions from (including) 7.0.0 up to (including)7.0.84","rangeStartType": "including","rangeStartVersion": "7.0.0","rangeEndType": "including","rangeEndVersion": "7.0.84","rangeId": "241999","rangeCpes": []
                        }
                    ],"containers": []
                }
            ]
        }]

我得到的输出如下：

public class Cpe    {
        public int depth { get; set; } 
        public bool vulnerable { get; set; } 
        public bool previous { get; set; } 
        public string urlName { get; set; } 
        public string cpe23Uri { get; set; } 
        public string cpe22Uri { get; set; } 
        public object status { get; set; } 
        public object resultingCpes { get; set; } 
        public string dataTestId { get; set; } 
        public string id { get; set; } 
        public List<object> matchCpes { get; set; } 
        public string rangeDescription { get; set; } 
        public string rangeStartType { get; set; } 
        public string rangeStartVersion { get; set; } 
        public string rangeEndType { get; set; } 
        public string rangeEndVersion { get; set; } 
        public string rangeId { get; set; } 
        public List<object> rangeCpes { get; set; } 
    }

    public class Container    {
        public string operator { get; set; } 
        public int depth { get; set; } 
        public string dataTestId { get; set; } 
        public string configType { get; set; } 
        public string cpeListType { get; set; } 
        public List<Cpe> cpes { get; set; } 
        public List<object> containers { get; set; } 
    }

    public class MyArray    {
        public int id { get; set; } 
        public string dataTestId { get; set; } 
        public int totalCpeCount { get; set; } 
        public List<Container> containers { get; set; } 
    }

    public class Root    {
        public List<MyArray> MyArray { get; set; } 
    }

并解析代码：

 Root result = JsonConvert.DeserializeObject<Root>(json); 

但是我得到一个错误：

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Tesr.Parser.Test.Root' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection,IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path '',line 1,position 1.

堆栈跟踪：

       at Newtonsoft.Json.JsonConvert.DeserializeObject[T](String value,JsonSerializerSettings settings)
       at Newtonsoft.Json.JsonConvert.DeserializeObject[T](String value)

我查看了所有字段，但ı无法提出解决方案。有人有什么想法吗？

解决方法

尝试一下。您的JSON根元素是一个数组。

List<Root> result = JsonConvert.DeserializeObject<List<Root>>(json);

,

在您的情况下，Root类似乎无法使用。为了工作，您需要将MyArray属性添加到原始json。

但是，我认为您最好的选择是使用：

List<MyArray> result = JsonConvert.DeserializeObject<List<MyArray>>(json);
