ServiceStack - FluentValidation

本文关键字：FluentValidation ServiceStack | 更新日期: 2023-09-27 18:02:03

我有一个关于使用FluentValidation与ServiceStack的问题。

例如:

[Route("/customers/{Id}", "PUT")]
public class UpdateCustomer : IReturn<Customer>
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}
[Route("/customers/{Id}", "DELETE")]
public class DeleteCustomer : IReturnVoid
{
    public int Id { get; set; }
}
public class Customer
{
    public int Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

当我更新客户信息时，我想验证所有参数，但是当我删除它时，我只想确保Id是正整数。FirstName LastName等等其他的我都不关心

如果我在客户类上实现FluentValidator，我将不得不将所有的逻辑放在验证器中(根据请求路由应用不同的规则)?或者有更优雅的方法?

ServiceStack - FluentValidation

验证器应该只在请求DTO上，例如:

public class UpdateCustomerValidator : AbstractValidator<UpdateCustomer>
{
    public UpdateCustomerValidator()
    {
        RuleFor(r => r.Id).GreaterThan(0);
        RuleFor(r => r.FirstName).NotEmpty();
        RuleFor(r => r.LastName).NotEmpty();
    }
}

， DeleteCustomer也一样，例如:

public class DeleteCustomerValidator : AbstractValidator<DeleteCustomer>
{
    public DeleteCustomerValidator()
    {
        RuleFor(r => r.Id).GreaterThan(0);
    }
}

虽然为单个字段创建一个完整的验证器可能有些多余，所以你可以直接在你的服务中添加验证，例如:

public class CustomerServices : Service
{
    public void Any(DeleteCustomer request)
    {
        if (request.Id <= 0)
            throw new ArgumentException("Id Required", "Id")
        Db.DeleteById<Customer>(request.Id);
    }
}
