ASP .NET核心更改默认ApiController BadResponse

// 自定义验证过滤器
public class CustomValidationFilterAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        if (!context.ModelState.IsValid)
        {
            // 处理验证错误，并返回自定义错误响应
            var errors = context.ModelState.Values.SelectMany(v => v.Errors)
                            .Select(e => e.ErrorMessage).ToList();
            var response = new { Message = "Validation errors", Errors = errors };
            context.Result = new ObjectResult(response)
            {
                StatusCode = (int)HttpStatusCode.BadRequest
            };
        }
    }
}

// 在控制器类中使用自定义验证过滤器
[ApiController]
[Route("api/[controller]")]
public class YourController : ControllerBase
{
    [HttpPost]
    [CustomValidationFilter]
    public IActionResult Post([FromBody] YourModel model)
    {
        // 处理请求逻辑
        // ...
        return Ok();
    }
}
