流利的验证条件规则

Question

我们有一个条件要求,即只有在打开标志时才应将空规则应用于字段.类似下面的代码.

这是正确的方法吗？

public AccountSetupModelValidator(ISessionProvider sessionProvider)
    {
        var regexPatterns = new RegExPatterns();

        RuleFor(x => x.MemorableDate)
            .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_1001_memorabledate);


        RuleFor(x => x.MemorableDateAnswer)
            .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_1001_memorabledateanswer)
            .Matches(regexPatterns.MemorableDateFormat).WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_memorabledateinvalidformat)
            .Length(5).WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100006_maxlength);

       RuleFor(x => x.SecurityQuestion)
           .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_1001_securityquestion);

        RuleFor(x => x.SecurityAnswer)
            .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_1001_securityanswer) 
            .Length(1, 40).WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100006_maxlength);

        if (sessionProvider.OnboardingApplicationData.ToggleNavigationView.HasProvisionalAccount)
        {

              RuleFor(x => x.TempCardNumber)
                .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard)
                .Matches(regexPatterns.NumericOnly)
                .WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_numbersonly)
                .Length(15).WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard);

            RuleFor(x => x.SecurityCode)
                .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard)
                .Matches(regexPatterns.NumericOnly)
                .WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_numbersonly)
                .Length(4).WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_securitycode);
        }

    }

我建议不要尝试依赖你的sessionProvider,因为这会让你更难独立地测试你的验证器.

相反,请使用FluentValidation的条件When()和Until()方法.

如果您的属性HasProvisionalAccount是(或可以放在)模型类,您可以重写这样的部分:

// remove the if() statement, and use .When()
RuleFor(x => x.TempCardNumber)
    .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard)
    .Matches(regexPatterns.NumericOnly)
    .WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_numbersonly)
    .Length(15).WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard)
    .When(x => x.HasProvisionalAccount);

RuleFor(x => x.SecurityCode)
    .NotEmpty().WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_tempcard)
    .Matches(regexPatterns.NumericOnly)
    .WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_numbersonly)
    .Length(4).WithLocalizedMessage(ResourceAreas.Messages.Message_AccountSetup_100006_securitycode)
    .When(x => x.HasProvisionalAccount);

每个规则仅在HasProvisionalAccount为true时执行.
