1、新建UserDto.cs

public class UserDto : BaseDto{private string userName;/// <summary>/// 用户名/// </summary>public string UserName{get { return userName; }set { userName = value;OnPropertyChanged(); }}private string account;/// <summary>/// 账户/// </summary>public string Account{get { return account; }set { account = value; OnPropertyChanged(); }}private string password;/// <summary>/// 密码/// </summary>public string Password{get { return password; }set { password = value; OnPropertyChanged(); }}}

2、新增ILoginService接口

   public interface ILoginService{Task<ApiResponse> LoginAsync(string Account, string Password);Task<ApiResponse> RegisterAsync(UserDto userDto);}

3、实现LoginService接口

public class LoginService : ILoginService{private readonly IUnitOfWork unitOfWork;private readonly IMapper mapper;public LoginService(IUnitOfWork unitOfWork, IMapper mapper){this.unitOfWork = unitOfWork;this.mapper = mapper;}/// <summary>/// 登录/// </summary>/// <param name="Account"></param>/// <param name="Password"></param>/// <returns></returns>public async Task<ApiResponse> LoginAsync(string Account, string Password){try{var repository = unitOfWork.GetRepository<User>();var model = await repository.GetFirstOrDefaultAsync(predicate: t => t.Account.Equals(Account) && t.PassWord.Equals(Password));if(model == null){return new ApiResponse(false, "用户名或密码错误！");}else{return new ApiResponse(true, model);}}catch (Exception ex){return new ApiResponse(false, ex.Message);}}/// <summary>/// 注册/// </summary>/// <param name="userDto"></param>/// <returns></returns>/// <exception cref="NotImplementedException"></exception>public async Task<ApiResponse> RegisterAsync(UserDto userDto){try{var user = mapper.Map<User>(userDto);var repository = unitOfWork.GetRepository<User>();var userModel = await repository.GetFirstOrDefaultAsync(predicate: t => t.Account.Equals(user.Account));if(userModel != null){return new ApiResponse(false, $"当前账号{user.Account}已存在，请重新注册！");}else{user.CreateDate = DateTime.Now;await repository.InsertAsync(user);if(await unitOfWork.SaveChangesAsync() > 0){return new ApiResponse(true, user);}else{return new ApiResponse(false, "注册失败！");}}}catch (Exception ex){return new ApiResponse(false, ex.Message);}}}

4、新增登录控制器LoginController

/// <summary>/// 登录/// </summary>public class LoginController : BaseApiController{private readonly ILoginService loginService;public LoginController(ILoginService loginService){this.loginService = loginService;}[HttpGet]public async Task<ApiResponse> Login(string Account, string PassWord){return await loginService.LoginAsync(Account, PassWord);}[HttpPost]public async Task<ApiResponse> Register([FromBody] UserDto userDto){return await loginService.RegisterAsync(userDto);}}

5、添加AutoMapper映射关系

  CreateMap<User, UserDto>().ReverseMap();

6、在program.cs里面添加服务

builder.Services.AddTransient<ILoginService, LoginService>();

7、F5运行项目
