如何在发送 GET 请求时从响应体中的 Json 中获取对象的值？

Question

我正在尝试从存储过程传递 JSON。所以我将它作为字符串传递，实体 class 包含从存储过程中捕获此字符串的字符串数据类型。

存储过程：

CREATE PROCEDURE [dbo].[CreateJson]
    @AppointmentID int
AS
    DECLARE @JsonOutput AS nvarchar(max)
BEGIN
    SET NOCOUNT ON;

    SET @JsonOutput = (SELECT TOP 1 AppointmentID, ReturnCode
                       FROM appointments
                       WHERE appointmentID = @AppointmentID
                       FOR JSON PATH, WITHOUT_ARRAY_WRAPPER) 

    SELECT @JsonOutput AS Details
END

实体class:

public partial class sp_test
{
    public string Details { get; set; }
}

API 控制器：

[HttpGet]
public async Task<ActionResult<IEnumerable<sp_test>>> Getsp_test(int AppointmentID)
{
    string StoredJson = "exec CreateJson " +
            "@AppointmentID = " + AppointmentID;
    var result = await _context.sp_test.FromSqlRaw(StoredJson).ToListAsync();
    return result;
}

响应正文：

[
  {
    "details": "{\"AppointmentID\":1,\"ReturnCode\":1}"
  }
]

我想获取显示对应于详细信息的 JSON。我想使用那个 JSON 作为参数来调用另一个 API。我无法访问 JSON.

有人可以帮帮我吗？

我正在使用此代码获取数据

var appointemntId= ...from your code
using (var client = new HttpClient())
{
    var baseAddress = "http://...";
   
     var api = "/< controllerName >/Getsp_test?AppointmentId="+appointmentId.ToString();

    client.BaseAddress = new Uri(baseAddress);
    var contentType = new MediaTypeWithQualityHeaderValue("application/json");
    client.DefaultRequestHeaders.Accept.Add(contentType);
    var response = await client.GetAsync(api);
    var statusCode = response.StatusCode.ToString();
    if (response.IsSuccessStatusCode)
    {
        var json= await response.Content.ReadAsStringAsync();
        var result = JsonConvert.DeserializeObject<List<sp_test>>(json);
    }
}
