ASP.NET服務發送JSON響應

Question

我正在嘗試讓我的服務發送JSON響應以及狀態碼，但不確定如何做到這一點。 例如，作為對POST請求的響應，我想發送201 Created響應。 到目前為止，我所擁有的是這個。

EmployeeApiController.cs

[RoutePrefix("api/employee")]
[EnableCors(origins: "*", headers: "*", methods: "*")]
public class EmployeeApiController : ApiController
{

    readonly EmployeePersistence persistence;


    public EmployeeApiController()
    {
        persistence = new EmployeePersistence();
    }

    [HttpPost]
    [Route("")]
    public HttpResponseMessage Post([FromBody]EmployeeDto employee)
    {
        long id = persistence.SaveEmployee(employee);

        // create http response
        HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created);
        response.Headers.Location = new Uri(Request.RequestUri, String.Format("/api/employee/{0}", id));

        return response;
    }

現在返回text/html而不是JSON。 我嘗試將返回類型更改為IHttpActionResult ，然后return Json(response)但這沒有用。 應該怎么做？

將[Produces("application/json")]到您的類裝飾中

[Produces("application/json")]
[RoutePrefix("api/employee")]
[EnableCors(origins: "*", headers: "*", methods: "*")]

然后像這樣改變你的控制器方法

[HttpPost]
public IActionResult Post([FromBody]EmployeeDto employee)
{
    long id = persistence.SaveEmployee(employee);
    return Created('employee',new {id = id});
}

這應該解決問題
