dotnet core 5 Webapi 向 HTTPPOST 发送 Json 响应

Question

[HttpPost]
    public HttpResponseMessage Post([FromBody] clsTicketInfo ticketInfo)
    {
        try
        {
            var message = new HttpResponseMessage(HttpStatusCode.OK);
            var data = new Dictionary<string, string>
            {
              {"id","72832"},
              {"name","John"}
             };
            var jsonData = JsonConvert.SerializeObject(data);
            message.Content = new StringContent(jsonData, System.Text.Encoding.UTF8, "application/json");
             //      Request.CreateResponse()         
            return message;
           
        
        }
        catch (Exception ex)
        {
         return   new HttpResponseMessage(HttpStatusCode.BadRequest);
        }
            //HttpResponseMessage(HttpStatusCode.Created, ticketInfo);
    }

在这段代码中，我想在我的 HTTP POST 中发送 Status ok 和 JSON 数据，但它不起作用。我正在使用 dotnet core 版本 5。

Answer 1

你只需要这个

public ActionResult Post([FromBody] clsTicketInfo ticketInfo)
{
  return Ok( new  { id =72832, name = "John" } );
}

带有消息的http响应将由net mvc自动创建

Answer 2

[HttpPost]
    public IActionResult HttpResponseMessage Post([FromBody] clsTicketInfo ticketInfo)
    {
        try
        {
                
              var data = new Dictionary<string, string>
                        {
                           {"id","72832"},
                           {"name","John"}
              
                         };
           var jsonData = JsonConvert.SerializeObject(data);
            return ok(jsonData);
           
        
        }
        catch (Exception ex)
        {
         return  Badrequest('error':ex.message)
        }
            
    }

IActionResult 可以在使用 ok,badrequest, notfound 时向前端发送响应。
