前兩篇文章主要實現了經銷商代註冊的倉儲與領域邏輯、經銷商登陸的倉儲與相關邏輯，這篇文章主要講述經銷商代註冊的用例與經銷商登陸的查詢功能。微信

一.經銷商代註冊用例

在經銷商代註冊用例中，咱們須要傳遞經銷商的基本註冊信息，這個信息是作成了DTO對象。ssh

1.經銷商註冊的DTO對象：

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; }
}
複製代碼

在上述DTO對象中，Name和Tel屬性是子經銷商的名字和電話號碼；EleMoney表明子經銷商註冊時的電子幣，從領域邏輯中能夠看到，電子幣會從父經銷商扣除並附加到子經銷商，而且根據EleMoney肯定了子經銷商的級別；Parentid是當前登陸的父經銷商的Id；其餘剩餘屬性是子經銷商的聯繫信息。ide

2.經銷商註冊用例：

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;
        }
    }
}
複製代碼

從上面代碼能夠看到，調用了註冊經銷商的邏輯，而且調用了相關倉儲進行父經銷商電子幣扣除、將父經銷商子個數加一、並持久化子經銷商信息，若是父經銷商的子經銷商個數超過2個，則拋出OverTowSubException異常。ui

這裏再也不講述經銷商註冊的WebApi實現，能夠參考前面的文章實現相應的WebApi。this

二.經銷商登陸功能

經銷商登陸時，只須要傳遞電話號碼和密碼就能夠了，因此先定義相關的DTO對象。idea

1.經銷商登陸的DTO對象

public class UserLoginDTO
{
    public string Telphone { get; set; }
    public string Password { get; set; }
}
複製代碼

2.經銷商登陸查詢

經銷商登陸這個功能不是一個用例，應該叫查詢，調用前面文章實現的查詢邏輯便可實現。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;
        }
    }
}
複製代碼

3.經銷商登陸的WebApi

在前一篇文章中，咱們實現了登陸成功時令牌生成的邏輯，因此在WebApi中，若是經銷商登陸成功，咱們將返回經銷商的Id、電話號碼與Token信息，這些信息存儲到一個DTO對象中。code

public class UserLoginResultDTO
{
    public string Tel { get; set; }
    public Guid DealerId { get; set; }
    public string Token { get; set; }
}
複製代碼

而後實現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 = "登陸成功!";
            }
            else
            {
                result.ErrorCode = 300;
                result.Msg = "登陸失敗!";
            }

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