Question

我正在尝试让我的服务发送JSON响应以及状态代码，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就是这个。

EmployeeApiController.cs

  const createMarkUp = (id) => {
    const markUp = `<div class="tile  tile--game"  data-name="${id}">
      <div class="tile__side  tile__side--front">
      </div>
      <div class="tile__side  tile__side--back">
        <img src="img/${id}.svg" alt="${id}" class="tile__img">
      </div>
    </div>`;
    return markUp;
  };

  //...

  const compare = (e) => {
    guesses.add(e.currentTarget);
    if (guesses.size !== 2) return;
    if (new Set(Array.from(guesses, guess => guess.dataset.name)).size == 1) {
        console.log("win");
        guesses = new Set;
        return;
    }
    setTimeout(() => {
      for (let guess of guesses) {
        guess.classList.remove("tile--active");
      }
      guesses = new Set;
    }, 500);
  }

现在返回[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; }而不是JSON。我尝试将我的返回类型更改为text/html然后IHttpActionResult，但这不起作用。应该怎么做？

将[Produces("application/json")]添加到您的班级装饰

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

并改变你这样的控制器方法

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

这应解决问题
