[HttpGet]
public IHttpActionResult GetContentResult()
{
return Content<string>(HttpStatusCode.OK, "OK");
}
向客户端返回值和http状态码。
4.2、BadRequest()
[HttpGet]
public IHttpActionResult GetBadRequest(ORDER order)
{
if (string.IsNullOrEmpty(order.ID))
return BadRequest();
return Ok();
}
向客户端返回400的http错误。
4.3、Redirect(string location)
[HttpGet]
public IHttpActionResult RedirectResult()
{
return Redirect("http://www.easck.com// 摘要:
// Defines a command that asynchronously creates an System.Net.Http.HttpResponseMessage.
public interface IHttpActionResult
{
// 摘要:
// Creates an System.Net.Http.HttpResponseMessage asynchronously.
//
// 参数:
// cancellationToken:
// The token to monitor for cancellation requests.
//
// 返回结果:
// A task that, when completed, contains the System.Net.Http.HttpResponseMessage.
Task<System.Net.Http.HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken);
}
}
这个接口包含唯一的一个方法ExecuteAsync()，此方法将以异步方式创建一个HttpResponseMessage实例返回给客户端。
有了这个作为基础，下面，我们自定义一个bootstrapTable服务端分页的子类去展示自定义IHttpActionResult的用法。
首先，自定义一个实现类
public class PageResult : IHttpActionResult
{
object _value;
HttpRequestMessage _request;
public PageResult(object value, HttpRequestMessage request)
{
_value = value;
_request = request;
}
public Task<HttpResponseMessage> ExecuteAsync(System.Threading.CancellationToken cancellationToken)
{
var response = new HttpResponseMessage()
{
Content = new ObjectContent(typeof(object), _value, new JsonMediaTypeFormatter()),
RequestMessage = _request
};
return Task.FromResult(response);
}
}
