Question

我在从JSON帖子数据中找出模型时遇到了麻烦。

JSON：

{  
"http://www.xxxx.com/":{  
    "articulo":[  
        {  
            "descripcion":{  
                "innerHTML":"Newskill Nukite Ratón Gaming MMO/MOBA RGB 16000 DPI",
                "nodeName":"SPAN",
                "treeDepth":17,
                "className":"",
                "childNodesLength":1,
                "childrenLength":0,
                "clientHeight":0,
                "parentNodeName":"A",
                "parentChildNodeslength":1
            },
            "img":{  
                "innerHTML":"",
                "nodeName":"IMG",
                "treeDepth":17,
                "className":"",
                "childNodesLength":0,
                "childrenLength":0,
                "height":210,
                "clientHeight":210,
                "parentNodeName":"A",
                "parentChildNodeslength":3
            }
        },
        {  
            "comentarios":{  
                "innerHTML":"(52)",
                "nodeName":"SPAN",
                "treeDepth":20,
                "className":"",
                "childNodesLength":1,
                "childrenLength":0,
                "clientHeight":0,
                "parentNodeName":"DIV",
                "parentChildNodeslength":15
            }
        }
    ]
}

}

我的模特：

public class GreatClass
{
    public IList url { get; set; } = new List<KeyValuePair<string, IList>>();
    private IList groups { get; set; } = new List<KeyValuePair<string, IList[]>>();
    public IList[] subGroups { get; set; }
    private IList metadata { get; set; } = new List<KeyValuePair<string, MetadataJSON>>();

    public partial class MetadataJSON
    {
        public string innerHTML { get; set; }
        public string nodeName { get; set; }
        public int treeDepth { get; set; }
        public string className { get; set; }
        public int childNodesLength { get; set; }
        public int childrenLength { get; set; }
        public Nullable<int> height { get; set; }
        public int clientHeight { get; set; }
        public string parentNodeName { get; set; }
        public int parentChildNodesLength { get; set; }
        public string name { get; set; }
    }
}

我在这里有另一个疑问：我应该删除new List<KeyValuePair<string, IList>>(); new List<KeyValuePair<string, IList[]>>();，= new List<KeyValuePair<string, MetadataJSON>>();声明吗？

因此，遵循该计划并从下到上：

我有静态数据，他们将永远存在 - MetadataJSON - 。
我有一个按键的字符串列表，其中MetadataJSON是值。
该列表是包含其他列表的数组（articulo）的元素。
然后我有另一个列表，其中字符串为键，列表数组为值。
最后，我有另一个列表，其中包含字符串作为键，包含列表作为值。

我有点失落，因为我认为我的逻辑实现是正常的，错误可能是在JSON的生成。

当然，我的控制器方法：

[HttpPost]
    public ActionResult GetJSONData(GreatClass JSONData)
    {
        if (ModelState.IsValid)
        {
            return Json(JSONData);
        }
        else
        {
            string errorMessage = "<div class=\"validation-summary-errors\">"
              + "The following errors occurred:<ul>";
            foreach (var key in ModelState.Keys)
            {
                var error = ModelState[key].Errors.FirstOrDefault();
                if (error != null)
                {
                    errorMessage += "<li class=\"field-validation-error\">"
                     + error.ErrorMessage + "</li>";
                }
            }
            errorMessage += "</ul>";
            return Json(errorMessage);
        }
    }

Answer 1

您正在发送一个具有名为"http://www.xxxx.com/"的属性的对象，您在C＃模型中没有这个属性（并且您不能有这样的名称）。您需要发送具有以下结构的对象：

{  
    "innerHTML":"Newskill Nukite Ratón Gaming MMO/MOBA RGB 16000 DPI",
    "nodeName":"SPAN",
    "treeDepth":17,
    "className":"",
    "childNodesLength":1,
    "childrenLength":0,
    "clientHeight":0,
    "parentNodeName":"A",
    "parentChildNodeslength":1
}

Answer 2

我＆＃34;解决了＃34;我使用IDictionary和修改JSON的问题（我对如何使用原始JSON解决它没有其他想法）。

public class GreatClass
{
    public IDictionary<string, IDictionary<string, IDictionary<string, MetadataJSON>[]>> url { get; set; }

    public partial class MetadataJSON
    {
        public string innerHTML { get; set; }
        public string nodeName { get; set; }
        public int treeDepth { get; set; }
        public string className { get; set; }
        public int childNodesLength { get; set; }
        public int childrenLength { get; set; }
        public Nullable<int> height { get; set; }
        public int clientHeight { get; set; }
        public string parentNodeName { get; set; }
        public int parentChildNodesLength { get; set; }
        public string name { get; set; }
    }
}

和JSON：

{
"url":
[
    { 
        Key: 'http://xxxx.com', Value: 
        [
            {
                Key: 'articulos', Value:   
                [
                    {  
                        "descripcion":{  
                            "innerHTML":"Newskill Nukite Ratón Gaming MMO/MOBA RGB 16000 DPI",
                            "nodeName":"SPAN",
                            "treeDepth":17,
                            "className":"",
                            "childNodesLength":1,
                            "childrenLength":0,
                            "clientHeight":0,
                            "parentNodeName":"A",
                            "parentChildNodeslength":1
                        },
                        "img":{  
                            "innerHTML":"",
                            "nodeName":"IMG",
                            "treeDepth":17,
                            "className":"",
                            "childNodesLength":0,
                            "childrenLength":0,
                            "height":210,
                            "clientHeight":210,
                            "parentNodeName":"A",
                            "parentChildNodeslength":3
                        }
                    },
                    {  
                        "comentarios":{  
                            "innerHTML":"(52)",
                            "nodeName":"SPAN",
                            "treeDepth":20,
                            "className":"",
                            "childNodesLength":1,
                            "childrenLength":0,
                            "clientHeight":0,
                            "parentNodeName":"DIV",
                            "parentChildNodeslength":15
                        }
                    }      
                ]
            }
        ]                                    
    }
]

}

如果你设法在没有编辑原始JSON的情况下解决它，那将非常感激。
