ASP.NET服务发送JSON响应

Question

我正在尝试让我的服务发送JSON响应以及状态码，但不确定如何做到这一点。 例如，作为对POST请求的响应，我想发送201 Created响应。 到目前为止，我所拥有的是这个。

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;
    }

现在返回text/html而不是JSON。 我尝试将返回类型更改为IHttpActionResult ，然后return Json(response)但这没有用。 应该怎么做？

将[Produces("application/json")]到您的类装饰中

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

然后像这样改变你的控制器方法

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

这应该解决问题
