在ASP.NET Core中的操作方法上禁用模型验证

Question

我想在Controller中的特定Action方法上禁用模型验证。我有这种情况：

public class SomeDto

{

    public string Name { get; set; }

}

public class SomeDtoValidator : AbstractValidator<SomeDto>, ISomeDtoValidator

{

    public SomeDtoValidator ()

    {

        RuleFor(someDto=> someDto.Name).NotNull().WithMessage("Name property can't be null.");

    }

}

我有ISomeDtoValidator，因为我以自己的方式注册了所有验证器：

public class Startup

{

    // .... constructor ....

    public void ConfigureServices(IServiceCollection services)

    {

        services.AddOptions();

        services.AddMvc(setup => {

        //...others setups...

        }).AddFluentValidation();

        services.RegisterTypes(Configuration)

                .RegisterFluentValidation()

                .RegisterMappingsWithAutomapper()

                .RegisterMvcConfigurations();

    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, IConfiguration configuration)

    {

        // ...

    }

}

我在控制器中有此操作方法：

[DisableFormValueModelBinding]

public async Task<IActionResult> CreateSome(Guid someId, SomeDto someDto)

{

    //..... Manually binding someDto...

    var validator = new SomeValidator();

    validator.Validate(someDto);

    // Doing something more ........

    return Ok();

}       

我禁用了ModelBinding的MVC，因为我想在绑定SomeDto之前做一些事情，因此，我也不想在SomeDto上应用任何验证器。因此，有什么方法可以实现？例如，如下所示：

[DisableValidator] // Or [DisableValidator(typeof(SomeDtoValidator))] whatever

[DisableFormValueModelBinding]

public async Task<IActionResult> CreateSome(Guid someId, SomeDto someDto)

{

    //..... Manually binding someDto...

    var validator = new SomeValidator();

    validator.Validate(someDto);

    // Doing something more ........

    return Ok();

}

实现了自己的目标，仅在验证器中放置了一个RuleSet。当管道调用验证程序时，它不会进行验证，因为管道调用没有RuleSet。贝娄是我如何解决此问题的一个示例：public class CustomerValidator : AbstractValidator<Customer>{&nbsp; &nbsp; public CustomerValidator()&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; RuleSet("Manually", () =>&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; RuleFor(x => x.Surname).NotNull();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; RuleFor(x => x.Forename).NotNull();&nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; }}public ActionResult ActionWithoutValidationExecuted(Customer customer)&nbsp;{&nbsp; &nbsp; //..... Manually binding customer...&nbsp; &nbsp; var validator = new CustomerValidator();&nbsp; &nbsp; var validResult = validator.Validate(customer, ruleSet: "Manually");&nbsp; &nbsp; // Doing something more ........&nbsp; &nbsp; return Ok();}
