当类型为字符串时,来自Webhook的JSON帖子为null

我正在使用。NET 5 web api。我有一个webhook,可以发布到我的api。然而,当我收到字符串中的帖子时,它是空的。如果我创建一个类,那么。Net将为我解析JSON,但我需要字符串,而不是对象。非常感谢您的任何建议!

JSON POST示例(应用程序/JSON;字符集=UTF-8):

{
    "user_ip": "00.00.00.00",
    "date_start": "2022-01-01T14:05:27.546Z",
    "user_referrer": "N/A",
    "user_os": "Windows (deprecated)",
    "id": "000001",
    "items": [
        {
            "id": "1",
            "position": 2,
            "value": "01/01/2022"
        },
        {
            "id": "0",
            "position": 8,
            "value": "Smith"
        },
        {
            "id": "1",
            "position": 22,
            "value": "7843377133"
        },
        {
            "values": [
                {
                    "position": 2,
                    "value": "Coffee"
                },
                {
                    "position": 5,
                    "value": "Tea"
                }
            ],
            "id": "14",
            "position": 7
        },
        {
            "id": "15",
            "position": 8,
            "value": "This is a test for API"
        }
    ],
    "user_device": "Desktop"
}

端点- val 类型字符串为时为null:

    [ApiController]
    [Route("api/webhooks/[controller]")]
    public class FormController : BaseApiController
    {
       
        [HttpPost("Form")]
        public async Task<ActionResult> Form([FromBody] string val)
        {

           
            FormDataModel FS = new FormDataModel(){

                ResultJsonString = val  
               
            };

             return Ok(new {Data = FS});

        }

例如,您只能使用JObject输入参数,并使用ToString()将其转换为json

public async Task<ActionResult> Form([FromBody] JObject val)
{
          ResultJsonString = val.ToString();
         .... another code  
}

另一种方法是在发布到API之前序列化两次,在这种情况下,可以将字符串作为val,但这是非常糟糕的编码样式。

您需要一个模板对象来反序列化json,然后可以作为所创建对象的成员访问该字符串。i、 e。

[ApiController]
    [Route("api/webhooks/[controller]")]
    public class FormController : BaseApiController
    {
       
        [HttpPost("Form")]
        public async Task<ActionResult> Form([FromBody] CustomObject val)
        {

           
            FormDataModel FS = new FormDataModel(){

                ResultJsonString = val.items[0].value 
                //or whatever path it is to the string you're interested in
               
            };

             return Ok(new {Data = FS});

        }
