茂名营销型网站制作公司,提供信息门户网站搭建,购物app首页ui设计,建设银行网站官网为了验证api post上来的数据的有效性#xff0c;我们可以引入FluentValidation(详见https://fluentvalidation.net)。在asp.net mvc中#xff0c;使用的是模型验证#xff0c;通过在实体类上添加特性达到验证效果。FluentValidation的原理是通过实现AbstractValidatorT我们可以引入FluentValidation(详见https://fluentvalidation.net)。在asp.net mvc中使用的是模型验证通过在实体类上添加特性达到验证效果。FluentValidation的原理是通过实现AbstractValidatorT来实现对T实体类的验证通过不同折Rule来验证T中的属性更多验证规则 参见官网见如下实现public class Person
{public int Id { get; set; }public string Name { get; set; }public string Tel { get; set; }public string Email { get; set; }public DateTime Birthday { get; set; }public string IDCard { get; set; }public PersonAddress Address { get; set; }
}
public class PersonAddress
{public string Country { get; set; }public string Province { get; set; }public string City { get; set; }public string County { get; set; }public string Address { get; set; }public string Postcode { get; set; }
}/// summary
/// Person验证
/// /summary
public class PersonValidator : AbstractValidatorPerson
{public PersonValidator(IPersonService personService){RuleFor(p p.Name).NotNull().NotEmpty();RuleFor(p p.Email).NotNull().EmailAddress();RuleFor(p p.Birthday).NotNull();RuleFor(p p.IDCard).NotNull().NotEmpty().Length(18).When(p (DateTime.Now p.Birthday.AddYears(1))).WithMessage(p $出生日期为{p.Birthday}现在时间为{DateTime.Now},大于一岁CardID值必填);RuleFor(p p.Tel).NotNull().Matches(^(\d{3,4}-)?\d{6,8}$|^[1][3,4,5,8]\d{9}$).WithMessage(电话格式为0000-0000000或13000000000);RuleFor(p p.Address).NotNull();RuleFor(p p.Address).SetValidator(new PersonAddressValidator());//通过调用外部方法来验证RuleFor(p p.Id).Must(id personService.IsExist(id)).WithMessage(p $不存在id{p.Id}的用户);}
}
/// summary
/// Person Address验证
/// /summary
public class PersonAddressValidator : AbstractValidatorPersonAddress
{public PersonAddressValidator(){RuleFor(a a.Country).NotNull().NotEmpty();RuleFor(a a.Province).NotNull().NotEmpty();RuleFor(a a.City).NotNull().NotEmpty();RuleFor(a a.County).NotNull().NotEmpty();RuleFor(a a.Address).NotNull().NotEmpty();RuleFor(a a.Postcode).NotNull().NotEmpty().Length(6);}
}在mini api引入FluentValidation也很简单可以通过注入IValidatorT实现也可以注放AddFluentValidation用IValidatorFactory来获取Validator来实现验证代码如下using FluentValidation;
using FluentValidation.AspNetCore;
using System.Text;var builder WebApplication.CreateBuilder(args);
builder.Services.AddFluentValidation();
builder.Services.AddScopedIValidatorPerson, PersonValidator();
builder.Services.AddScopedIPersonService, PersonService();
var app builder.Build();app.MapPost(/person, async (IValidatorPerson validator, Person person) {var result await validator.ValidateAsync(person);if (!result.IsValid){var errors new StringBuilder();foreach (var valid in result.Errors){errors.AppendLine(valid.ErrorMessage);}return errors.ToString();}return OK;});app.MapPost(/person1, async (IValidatorFactory validatorFactory, Person person)
{var result await validatorFactory.GetValidatorPerson().ValidateAsync(person);if (!result.IsValid){var errors new StringBuilder();foreach (var valid in result.Errors){errors.AppendLine(valid.ErrorMessage);}return errors.ToString();}return OK;
});app.MapPost(/person2, async (IValidatorFactory validatorFactory, Person person)
{var result await validatorFactory.GetValidator(typeof(Person)).ValidateAsync(new ValidationContextPerson(person));if (!result.IsValid){var errors new StringBuilder();foreach (var valid in result.Errors){errors.AppendLine(valid.ErrorMessage);}return errors.ToString();}return OK;
});app.Run();public interface IPersonService
{public bool IsExist(int id);
}
public class PersonService : IPersonService
{public bool IsExist(int id){if (DateTime.Now.Second % 2 0){return false;}else{return true;}}
}
