前两篇文章主要实现了经销商代注册的仓储与领域逻辑、经销商登陆的仓储与相关逻辑，这篇文章主要讲述经销商代注册的用例与经销商登陆的查询功能。微信

一.经销商代注册用例

在经销商代注册用例中，咱们须要传递经销商的基本注册信息，这个信息是作成了DTO对象。ssh

1.经销商注册的DTO对象：

public class AddDealerDTO
{
    public string Name { get; set; }
    public string Tel { get; set; }
    public decimal EleMoney { get; set; }
    public Guid? Parentid { get; set; }
    public List<string> ContactNames { get; set; }
    public List<string> ContactTels { get; set; }
    public List<string> ContactProvinces { get; set; }
    public List<string> ContactCities { get; set; }
    public List<string> ContactZeors { get; set; }
    public List<string> ContactStreets { get; set; }
    public List<int> IsDefaultContact { get; set; }
}
复制代码

在上述DTO对象中，Name和Tel属性是子经销商的名字和电话号码；EleMoney表明子经销商注册时的电子币，从领域逻辑中能够看到，电子币会从父经销商扣除并附加到子经销商，而且根据EleMoney肯定了子经销商的级别；Parentid是当前登陆的父经销商的Id；其余剩余属性是子经销商的联系信息。ide

2.经销商注册用例：

public class AddDealerUseCase:BaseAppSrv
{
    private readonly IRepository irepository;
    private readonly IDealerRepository idealerrepository;
    private readonly ILoginRepository iloginrepository;
    public AddDealerUseCase(IRepository irepository, IDealerRepository idealerrepository,
        ILoginRepository iloginrepository)
    {
        this.irepository = irepository;
        this.idealerrepository = idealerrepository;
        this.iloginrepository = iloginrepository;
    }
    public ResultEntity<bool> AddDealer(AddDealerDTO adddealerdto)
    {
        var dealerid = Guid.NewGuid();
        var dealercontacts = new List<Contact>();
        for(int i = 0; i < adddealerdto.ContactNames.Count; i++)
        {
            var dealercontact = new Contact().CreateContact(dealerid, adddealerdto.ContactNames[i],
                adddealerdto.ContactTels[i], adddealerdto.ContactProvinces[i],
                adddealerdto.ContactCities[i], adddealerdto.ContactZeors[i], adddealerdto.ContactStreets[i],
                adddealerdto.IsDefaultContact[i]);
            dealercontacts.Add(dealercontact);
        }
        var dealer = new Dealers(idealerrepository).RegisterDealer(dealerid, adddealerdto.Name,
            adddealerdto.Tel, adddealerdto.EleMoney, dealercontacts, adddealerdto.Parentid);
        var login = new Login().CreateLogin(dealer.Tel, dealerid);
        try
        {
            using (irepository)
            {
                idealerrepository.CreateDealer(dealer);
                if (adddealerdto.Parentid != null)
                {
                    idealerrepository.SubParentEleMoney(Guid.Parse(adddealerdto.Parentid.ToString()),
                        adddealerdto.EleMoney);
                }
                idealerrepository.AddParentSubCount(adddealerdto.Parentid);
                iloginrepository.CreateLogin(login);

                irepository.Commit();
            }
            return GetResultEntity(true);
        }
        catch (OverTowSubException error)
        {
            throw error;
        }
        catch(Exception error)
        {
            throw error;
        }
    }
}
复制代码

从上面代码能够看到，调用了注册经销商的逻辑，而且调用了相关仓储进行父经销商电子币扣除、将父经销商子个数加一、并持久化子经销商信息，若是父经销商的子经销商个数超过2个，则抛出OverTowSubException异常。ui

这里再也不讲述经销商注册的WebApi实现，能够参考前面的文章实现相应的WebApi。this

二.经销商登陆功能

经销商登陆时，只须要传递电话号码和密码就能够了，因此先定义相关的DTO对象。idea

1.经销商登陆的DTO对象

public class UserLoginDTO
{
    public string Telphone { get; set; }
    public string Password { get; set; }
}
复制代码

2.经销商登陆查询

经销商登陆这个功能不是一个用例，应该叫查询，调用前面文章实现的查询逻辑便可实现。spa

public class UserLoginQuery:BaseAppSrv
{
    private readonly IRepository irepository;
    private readonly ILoginRepository iloginrepository;
    public UserLoginQuery(IRepository irepository, ILoginRepository iloginrepository)
    {
        this.iloginrepository = iloginrepository;
        this.irepository = irepository;
    }
    public Guid Login(UserLoginDTO userlogindto)
    {
        try
        {
            using (irepository)
            {
                return iloginrepository.UserLogin(userlogindto.Telphone, userlogindto.Password);
            }
        }
        catch(Exception error)
        {
            throw error;
        }
    }
}
复制代码

3.经销商登陆的WebApi

在前一篇文章中，咱们实现了登陆成功时令牌生成的逻辑，因此在WebApi中，若是经销商登陆成功，咱们将返回经销商的Id、电话号码与Token信息，这些信息存储到一个DTO对象中。code

public class UserLoginResultDTO
{
    public string Tel { get; set; }
    public Guid DealerId { get; set; }
    public string Token { get; set; }
}
复制代码

而后实现WebApi接口orm

[AllowAnonymous]
    [HttpPost]
    [Route("UserLogin")]
    public ResultEntity<UserLoginResultDTO> UserLogin([FromBody] UserLoginDTO userlogindto)
    {
        var result = new ResultEntity<UserLoginResultDTO>();
        var idealercontext = servicelocator.GetService<IDealerContext>();
        var irepository =
            servicelocator.GetService<IRepository>(new ParameterOverrides { { "context", idealercontext } });
        var iloginrepository = servicelocator.GetService<ILoginRepository>(new ParameterOverrides { { "context", idealercontext } });
        UserLoginQuery userloginquery = new UserLoginQuery(irepository, iloginrepository);
        try
        {
            var dealerid = userloginquery.Login(userlogindto);
            if (dealerid != Guid.Empty)
            {
                var token = new JwtTokenBuilder()
                    .AddSecurityKey(JwtSecurityKey.Create("msshcjsecretmsshcjsecret"))
                    .AddSubject(userlogindto.Telphone)
                    .AddIssuer("DDD1ZXSystem")
                    .AddAudience("DDD1ZXSystem")
                    .AddClaim("role", "NormalUser")                        
                    .AddExpiry(600)
                    .Build();

                var userloginresultdto = new UserLoginResultDTO();
                userloginresultdto.Tel = userlogindto.Telphone;
                userloginresultdto.DealerId = dealerid;
                userloginresultdto.Token = token.Value;

                result.IsSuccess = true;
                result.Data = userloginresultdto;
                result.Msg = "登陆成功!";
            }
            else
            {
                result.ErrorCode = 300;
                result.Msg = "登陆失败!";
            }

        }
        catch (Exception error)
        {
            result.ErrorCode = 200;
            result.Msg = error.Message;
        }
        return result;
    }
复制代码
