ASP.NET Core 过滤器返回自定义响应数据

自定义返回类

 public class ApiResponse
 {
     public int Code { get; set; }
     public string Message { get; set; }
     public object Data { get; set; }

     public ApiResponse(int code, string message, object data = null)
     {
         Code = code;
         Message = message;
         Data = data;
     }
 }

 ApiResultFilterAttribute

public class ApiResultFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(ActionExecutedContext context)
    {
        if (context.Result is ObjectResult objectResult)
        {
            var apiResponse = new ApiResponse(200, "成功", objectResult.Value);
            context.Result = new ObjectResult(apiResponse);
        }
        else if (context.Result is EmptyResult)
        {
            var apiResponse = new ApiResponse(200, "成功");
            context.Result = new ObjectResult(apiResponse);
        }

        base.OnActionExecuted(context);
    }
}

ApiExceptionFilterAttribute

public class ApiExceptionFilterAttribute : ExceptionFilterAttribute
{
  
       public override void OnException(ExceptionContext context)
    { 
        var exceptionDetail = context.Exception.Message;
        var innerException = context.Exception.InnerException != null ? $" Inner exception: {context.Exception.InnerException.Message}" : string.Empty;

        var apiResponse = new ApiResponse(400, exceptionDetail + innerException);

        context.Result = new ObjectResult(apiResponse);
   
        context.ExceptionHandled = true;
    } 
}

在progarm.cs注册

builder.Services.AddControllers(options =>
{

    options.Filters.Add<ApiResultFilterAttribute>(); 
    options.Filters.Add<ApiExceptionFilterAttribute>(); 
});
