如何在asp.net api requrest中传递JSON数据，在控制器操作中使用哪种类型的参数？

我有以下JSON数据：

{
    "0": {
        "id": 0,
        "type": "camera",
        "option": [
            {
                "optionId": 1,
                "optionValue": "",
                "answered": "false",
                "lastanswerd": "false"
            }
        ]
    },
    "1": {
        "id": 1,
        "type": "checkCategory",
        "option": [
            {
                "optionId": 1,
                "optionValue": "",
                "answered": "false",
                "lastanswerd": "false"
            },
            {
                "optionId": 2,
                "optionValue": "",
                "answered": "false",
                "lastanswerd": "false"
            }           
        ]
    }
}

请建议我，这对我来说是新的。

如果您将json更改为：

[
  {
    "id": 0,
    "type": "camera",
    "option": [
      {
        "optionId": 1,
        "optionValue": "",
        "answered": "false",
        "lastanswerd": "false"
      }
    ]
  },
  {
    "id": 1,
    "type": "checkCategory",
    "option": [
      {
        "optionId": 1,
        "optionValue": "",
        "answered": "false",
        "lastanswerd": "false"
      },
      {
        "optionId": 2,
        "optionValue": "",
        "answered": "false",
        "lastanswerd": "false"
      }
    ]
  }
]

http://json2csharp.com/告诉我们：

public class Option
{
    public int optionId { get; set; }
    public string optionValue { get; set; }
    public string answered { get; set; }
    public string lastanswerd { get; set; }
}

public class RootObject
{
    public int id { get; set; }
    public string type { get; set; }
    public List<Option> option { get; set; }
}

Asp.net MVC自动化并尝试转换每个键：json的值。

{"key1":"value", "key2":"value"}

您可以使用函数中的参数

来访问这些值

public ActionResult Index(string key,string key2)

或者创建一个公共setter等于你的键和无参数构造函数的类。

public Class MyJson
{
    public string key1 {get;set;}
    public string key2 {get;set;}
}

public ActionResult Index(MyJson model)

在您的特定情况下，您传递一个对象列表，因此您应该使用

public ActionResult Index(List<MyJson> model)

对ASP.NET API的JSON请求
