我正在寻找在我的. net核心Web API控制器中返回带有HTTP状态代码的JSON的正确方法。我以前是这样用的:
public IHttpActionResult GetResourceData()
{
return this.Content(HttpStatusCode.OK, new { response = "Hello"});
}
这是在一个4.6 MVC应用程序，但现在与。net核心，我似乎没有这个IHttpActionResult，我有ActionResult和使用像这样:
public ActionResult IsAuthenticated()
{
return Ok(Json("123"));
}
但是服务器的反应很奇怪，如下图所示:
我只是想让Web API控制器返回带有HTTP状态码的JSON，就像我在Web API 2中所做的那样。

请参考以下代码，您可以管理多个状态代码与不同类型的JSON
public async Task<HttpResponseMessage> GetAsync()
{
try
{
using (var entities = new DbEntities())
{
var resourceModelList = entities.Resources.Select(r=> new ResourceModel{Build Your Resource Model}).ToList();
if (resourceModelList.Count == 0)
{
return this.Request.CreateResponse<string>(HttpStatusCode.NotFound, "No resources found.");
}
return this.Request.CreateResponse<List<ResourceModel>>(HttpStatusCode.OK, resourceModelList, "application/json");
}
}
catch (Exception ex)
{
return this.Request.CreateResponse<string>(HttpStatusCode.InternalServerError, "Something went wrong.");
}
}
其他回答
我在这里找到了很棒的答案，我还尝试了这个返回语句，见StatusCode(任何你想要的代码)，它工作了!!
return Ok(new {
Token = new JwtSecurityTokenHandler().WriteToken(token),
Expiration = token.ValidTo,
username = user.FullName,
StatusCode = StatusCode(200)
});
请参考以下代码，您可以管理多个状态代码与不同类型的JSON
public async Task<HttpResponseMessage> GetAsync()
{
try
{
using (var entities = new DbEntities())
{
var resourceModelList = entities.Resources.Select(r=> new ResourceModel{Build Your Resource Model}).ToList();
if (resourceModelList.Count == 0)
{
return this.Request.CreateResponse<string>(HttpStatusCode.NotFound, "No resources found.");
}
return this.Request.CreateResponse<List<ResourceModel>>(HttpStatusCode.OK, resourceModelList, "application/json");
}
}
catch (Exception ex)
{
return this.Request.CreateResponse<string>(HttpStatusCode.InternalServerError, "Something went wrong.");
}
}
这是我最简单的解决方案:
public IActionResult InfoTag()
{
return Ok(new {name = "Fabio", age = 42, gender = "M"});
}
or
public IActionResult InfoTag()
{
return Json(new {name = "Fabio", age = 42, gender = "M"});
}

同步动作
[HttpGet("{id}")]
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status404NotFound)]
public ActionResult<Product> GetById(int id)
{
if (!_repository.TryGetProduct(id, out var product))
{
return NotFound();
}
return product;
}
异步操作
[HttpPost]
[Consumes(MediaTypeNames.Application.Json)]
[ProducesResponseType(StatusCodes.Status201Created)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
public async Task<ActionResult<Product>> CreateAsync(Product product)
{
if (product.Description.Contains("XYZ Widget"))
{
return BadRequest();
}
await _repository.AddProductAsync(product);
return CreatedAtAction(nameof(GetById), new { id = product.Id }, product);
}
我在我的Asp Net Core Api应用程序中所做的是创建一个从ObjectResult扩展的类，并提供许多构造函数来定制内容和状态代码。 然后我所有的控制器动作都使用适当的构造函数之一。 你可以看看我的实现: https://github.com/melardev/AspNetCoreApiPaginatedCrud
and
https://github.com/melardev/ApiAspCoreEcommerce
下面是类的样子(去我的回购完整代码):
public class StatusCodeAndDtoWrapper : ObjectResult
{
public StatusCodeAndDtoWrapper(AppResponse dto, int statusCode = 200) : base(dto)
{
StatusCode = statusCode;
}
private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, string message) : base(dto)
{
StatusCode = statusCode;
if (dto.FullMessages == null)
dto.FullMessages = new List<string>(1);
dto.FullMessages.Add(message);
}
private StatusCodeAndDtoWrapper(AppResponse dto, int statusCode, ICollection<string> messages) : base(dto)
{
StatusCode = statusCode;
dto.FullMessages = messages;
}
}
注意用对象替换dto的基数(dto)应该没问题了。
