asp.net-mvc - FluentValidation Autofac ValidatorFactory

Question

我需要能够向我的 ValidatorFactory 提供 IComponentContext 来解析 FluentValidation 验证器。我有点卡住了。

验证器工厂

    public class ValidatorFactory : ValidatorFactoryBase
    {
        private readonly IComponentContext context;

        public ValidatorFactory(IComponentContext context)
        {
            this.context = context;
        }

        public override IValidator CreateInstance(Type validatorType)
        {
            return context.Resolve(validatorType) as IValidator;
        }
    }

如何提供上下文并注册 ValidatorFactory

FluentValidation.Mvc.FluentValidationModelValidatorProvider.Configure(x => x.ValidatorFactory = new ValidatorFactory());

您可以使其普遍适用于任何DependencyResolver，而不是将其与Autofac紧密耦合。直接使用它:

public class ModelValidatorFactory : IValidatorFactory
{
  public IValidator GetValidator(Type type)
  {
    if (type == null)
    {
      throw new ArgumentNullException("type");
    }
    return DependencyResolver.Current.GetService(typeof(IValidator<>).MakeGenericType(type)) as IValidator;
  }

  public IValidator<T> GetValidator<T>()
  {
    return DependencyResolver.Current.GetService<IValidator<T>>();
  }
}

然后您可以使用任何类型的 DependencyResolver 注册您的验证器作为强类型 IValidator<T>并且最终总会得到解决。
