Microsoft.AspNetCore.Http.IFileHttpResult
Microsoft.AspNetCore.Http.INestedHttpResult
Microsoft.AspNetCore.Http.IStatusCodeHttpResult
Microsoft.AspNetCore.Http.IValueHttpResult
Microsoft.AspNetCore.Http.IValueHttpResultTValue可以参考 PRhttps://github.com/dotnet/aspnetcore/pull/42385/files如果我们想要匹配 response 的返回值就可以使用 IValueHttpResult 来匹配比如if (result is IValueHttpResult valueHttpResult)return valueHttpResult.Value;也可以使用 IStatusCodeHttpResult 来匹配 response statusif (result is IStatusCodeHttpResult statusCodeResult)return statusCodeResult.StatusCode;ApiResultFilter实现了一个简单的统一 response 的 ApiResultFilter 在原来的基础上增加了 EndpointFilter 的支持实现如下[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple false, Inherited true)]
public sealed class ApiResultFilter : Attribute, IResultFilter, IExceptionFilter
#if NET7_0_OR_GREATER, IEndpointFilter
#endif{public void OnResultExecuting(ResultExecutingContext context){if (context.Result is ObjectResult { Value: not Result } objectResult){var result new Resultobject(){Data objectResult.Value,Status HttpStatusCode2ResultStatus(objectResult.StatusCode)};objectResult.Value result;}}public void OnResultExecuted(ResultExecutedContext context){}public void OnException(ExceptionContext context){var result Result.Fail(context.Exception.ToString(), ResultStatus.ProcessFail);context.Result new ObjectResult(result) { StatusCode 500 };}
#if NET7_0_OR_GREATERpublic async ValueTaskobject InvokeAsync(EndpointFilterInvocationContext context, EndpointFilterDelegate next){try{var result await next(context);if (result is Result or ObjectResult { Value: Result } or IValueHttpResult { Value: Result }){return result;}if (result is ObjectResult { Value: not Result } objectResult){return new Resultobject(){Data objectResult.Value, Status HttpStatusCode2ResultStatus(objectResult.StatusCode)};}if (result is IValueHttpResult { Value: not Result } valueHttpResult){var status result is IStatusCodeHttpResult statusCodeHttpResult? HttpStatusCode2ResultStatus(statusCodeHttpResult.StatusCode): HttpStatusCode2ResultStatus(200);return new Resultobject() { Data valueHttpResult.Value, Status status };}return new Resultobject(){Data result, Status HttpStatusCode2ResultStatus(context.HttpContext.Response.StatusCode)};}catch (Exception ex){return Result.Fail(ex.ToString(), ResultStatus.ProcessFail);}}
#endifprivate static ResultStatus HttpStatusCode2ResultStatus(int? statusCode){statusCode ?? 200;var status ResultStatus.Success;if (Enum.IsDefined(typeof(ResultStatus), statusCode.Value)){status (ResultStatus)statusCode.Value;}if (status ResultStatus.None){status ResultStatus.Success;}return status;}
}下面看一个使用的示例var app WebApplication.Create(args);
app.Map(/Hello, () Hello Minimal API!).AddEndpointFilterApiResultFilter();
app.Map(/HelloV3, () Results.Ok(new { Name test })).AddEndpointFilterApiResultFilter();
app.Map(/HelloV4, () Results.Ok(Result.Success(new { Name test }))).AddEndpointFilterApiResultFilter();
await app.RunAsync();访问一个直接返回一个字符串的接口访问返回一个 IResult 的接口访问返回一个 ResultModel 的 API使用控制器 API 示例[Route(api/[controller])]
public class ValuesController: ControllerBase
{[HttpGet([action])]public IActionResult Test(){return Ok(new { Name Amazing .NET });}
