Question

我需要实现自定义操作过滤器，以便可以自定义BadRequest响应，以针对端点参数的模型状态进行调用。

自定义操作过滤器看起来像-

 using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.AspNetCore.Mvc.ModelBinding;

namespace RestAPI.Extensions
{
    public class ValidateActionParametersAttribute:ActionFilterAttribute
    {
        public ValidateActionParametersAttribute()
        {
              //constructor gets called when endpoint is called 
              //with empty body , but not the overridden methods
        }
        public override void OnActionExecuted(ActionExecutedContext context)
        {
            throw new System.NotImplementedException();
        }

        public override void OnActionExecuting(ActionExecutingContext context)
        {
            //check various scenarios
            //like if model is null.
            //like arguments passed in correct syntax or not.
            base.OnActionExecuting(context);
        }
}

然后我在Startup.cs，ConfigureServices中注册此过滤器。

  //add action filter
        services.AddScoped<ValidateActionParametersAttribute>();

我的POST操作方法。

//My Controller is inherited from other controller which being base inherits from ControllerBase
[Produces(MediaTypeNames.Application.Json)]
public class AuthController : BaseApiController
{
        [Route("login")]
        [HttpPost]
        [ServiceFilter(typeof(ValidateActionParametersAttribute))]
        [ProducesResponseType(StatusCodes.Status200OK)]
        [ProducesResponseType(StatusCodes.Status400BadRequest)]
        [ProducesResponseType(StatusCodes.Status401Unauthorized)]
        [ProducesResponseType(StatusCodes.Status405MethodNotAllowed)]
        [ProducesResponseType(StatusCodes.Status503ServiceUnavailable)]
        [ProducesResponseType(StatusCodes.Status500InternalServerError)]
        public async Task<ActionResult> Login([FromBody]LoginInputModel login)
        {               
            //endpoint logic
        }
}

最后，我传递给Login端点的模型

 /// <summary>
/// model to be used as paramter body for login.
/// </summary>
public class LoginInputModel
{      
    [EmailAddress]
    [Required(ErrorMessage ="EmailId is needed")]
    [Display(Description ="Email for login",ResourceType =typeof(string))]
    public string Email { get; set; }
    
    [DataType(DataType.Password)]
    [Required]
    public string Password { get; set; }
   
    [Display(Name = "Remember me?")]
    public bool RememberMe { get; set; }

}

我想返回具有自定义结构的BadRequest响应，但就我而言，调试器只是没有使用OnActionExecuted()方法。.

我正在尝试使用空主体或无效输入来调用端点登录正文。

不执行操作过滤器，而是以某些自动生成的格式返回BadRequest响应。

我得到的样本响应-

有人可以帮我解决这个问题吗？
