ASP.NET Core中使用FluentValidation的集成实例

【实例简介】
FluentValidation是一个流行的.NET验证库，用于构建强类型的验证规则。尽管FluentValidation.AspNetCore包不再被维护，但我们可以通过手动验证方法将核心FluentValidation包与ASP.NET Core集成。

本文将引导你了解如何在ASP.NET Core项目中使用FluentValidation进行数据验证。首先，我们需要安装FluentValidation.AspNetCore NuGet包。然后，通过定义验证规则类（如PersonValidator）来创建验证规则。例如：

public class PersonValidator : AbstractValidator<Person> {
  public PersonValidator() {
    RuleFor(x => x.Id).NotNull();
    RuleFor(x => x.Name).Length(0, 10);
    RuleFor(x => x.Email).EmailAddress();
    RuleFor(x => x.Age).InclusiveBetween(18, 60);
  }
}

接下来，在Startup.cs中配置服务，注册验证器：

public void ConfigureServices(IServiceCollection services) {
    services.AddMvc();
    services.AddScoped<IValidator<Person>, PersonValidator>();
}

对于自动验证，需要在Startup.cs中添加额外的配置以启用FluentValidation的自动验证特性。但请注意，自动验证功能仅限于MVC控制器和Razor页面。
