Question

我有如下的Web api方法

public bool UpdateValidations([FromBody] ValidationKeyEntity validationKey)
{
    if (ModelState.IsValid)
    { 
        //my code here
    }
}

public class ValidationKeyEntity
{
    public int ValidationKeyId { get; set; }

    [MaxLength(Constants.maxStringLength)]
    public string Name { get; set; }

    public int DisplayId { get; set; }

    [MaxLength(Constants.maxStringLength)]
    public string CreatedBy { get; set; }
}

我正在使用Postman进行测试。我将与ValidationKeyEntity对象不同的json作为参数传递给{“ Vishal”：“ vishal”}。但我的 ModelState.IsValid仍返回true 。

如何避免接受“ ValidationKeyEntity”对象以外的其他json对象？

使用RequiredAttribute将属性标记为required：

public class ValidationKeyEntity
{
    [Required]
    public int ValidationKeyId { get; set; }

    [Required]
    public string Name { get; set; }

    [Required]
    public int DisplayId { get; set; }

    [Required]
    public string CreatedBy { get; set; }
}

全局设置MissingMemberHandling以处理废物属性：

var httpConfiguration = new HttpConfiguration();

httpConfiguration
                .Formatters
                .JsonFormatter
                .SerializerSettings
                .MissingMemberHandling = MissingMemberHandling.Error;
