Question

Put Action定义为int参数类型，并且我需要在发送字符串时响应自定义BadRequest消息，该响应应该仅适用于一个Controller

        [HttpPut("address")]
        [Authorize]
        [ProducesResponseType(typeof(Customer), 200)]
        [ProducesResponseType(typeof(Error), 400)]
        [ProducesResponseType(typeof(Error), 404)] //custom error
        [ProducesDefaultResponseType]
        public async Task<IActionResult> UpdateAddress(
            [Required] [FromForm] string email,
            [Required] [FromForm] string address_1,
                       [FromForm] string address_2,
            [Required] [FromForm] string city,
            [Required] [FromForm] string region,
            [Required] [FromForm] string postal_code,
            [Required] [FromForm] string country,
            [Required] [FromForm] int shipping_region_id //this is the parameter to validate
        )
        {
           //...
        }

BadRequest（400）消息应为：“运送地区ID不是数字” 如何在到达Controller并发送自定义BadRequest对象之前验证类型？

使用DTO进行PUT请求并像这样传递您的参数。

public class UpdateAddressDTO
{
        [Required]
        public string email { get; set; }
        [Required]
        public string address_1 { get; set; }
        [Required]
        public string address_2 { get; set; }
        [Required]
        public string city { get; set; }
        [Required]
        public string region { get; set; }
        [Required]
        public string postal_code { get; set; }
        [Required]
        public string country { get; set; }
}

[Route("address/{shipping_region_id}/update")]
public async Task<IActionResult> UpdateAddress([FromUri]int shipping_region_id, [FromBody]UpdateAddressDTO model)
{

}

验证操作的参数类型并发送自定义BadRequest“ [字段]不是数字”
