.*** 8 后端

项目目录结构

项目的引用依赖链为：WebAPI => Service => Infrastructure => Model。

本案例中，Test 层不会用到。

EF Core 与 Identity

1. 在 Model 层中安装 Microsoft.Asp***Core.Identity.EntityFrameworkCore Nuget 包

2. 在 Model.DbEntities 目录下新建 ApplicationRole、ApplicationUser 、UserInfo 实体类

   using Microsoft.Asp***Core.Identity;
   
   namespace CampusServicePlatform.Model.DbEntities
   {
       public class ApplicationRole : IdentityRole<Guid>
       {
       }
   }
   

   using Microsoft.Asp***Core.Identity;
   
   namespace CampusServicePlatform.Model.DbEntities
   {
       public class ApplicationUser : IdentityUser<Guid>
       {
           public virtual UserInfo? UserInfo { get; set; }
       }
   }
   

   namespace CampusServicePlatform.Model.DbEntities
   {
       public class UserInfo
       {
           public int Id { get; set; }
           public string? Nickname { get; set; }
           public string? Avatar { get; set; }
           public DateTime? CreatedTime { get; set; }
   
           public Guid UserId { get; set; }
   
           public virtual ApplicationUser? User { get; set; }
       }
   }
   

3. 在 Infrastructure 层中安装 Microsoft.EntityFrameworkCore.Design、Microsoft.EntityFrameworkCore.SqlServer、Microsoft.EntityFrameworkCore.Tools NuGet 包

4. 在 Infrastructure.DbEntityConfigs 目录下新建 ApplicationRoleEntityConfig、ApplicationUserEntityConfig、UserInfoEntityConfig 实体配置类

   using CampusServicePlatform.Model.DbEntities;
   using Microsoft.EntityFrameworkCore;
   using Microsoft.EntityFrameworkCore.Metadata.Builders;
   
   namespace CampusServicePlatform.Infrastructure.DbEntityConfigs
   {
       public class ApplicationRoleEntityConfig : IEntityTypeConfiguration<ApplicationRole>
       {
           public void Configure(EntityTypeBuilder<ApplicationRole> builder)
           {
           }
       }
   }
   

   using CampusServicePlatform.Model.DbEntities;
   using Microsoft.EntityFrameworkCore;
   using Microsoft.EntityFrameworkCore.Metadata.Builders;
   
   namespace CampusServicePlatform.Infrastructure.DbEntityConfigs
   {
       public class ApplicationUserEntityConfig : IEntityTypeConfiguration<ApplicationUser>
       {
           public void Configure(EntityTypeBuilder<ApplicationUser> builder)
           {
           }
       }
   }
   

   using CampusServicePlatform.Model.DbEntities;
   using Microsoft.EntityFrameworkCore;
   using Microsoft.EntityFrameworkCore.Metadata.Builders;
   
   namespace CampusServicePlatform.Infrastructure.DbEntityConfigs
   {
       public class UserInfoEntityConfig : IEntityTypeConfiguration<UserInfo>
       {
           public void Configure(EntityTypeBuilder<UserInfo> builder)
           {
               builder.Property(e => e.UserId).IsRequired();
               
               // 指定外键
               builder.HasOne(e => e.User).WithOne(e => e.UserInfo).HasForeignKey<UserInfo>(e => e.UserId).HasPrincipalKey<ApplicationUser>(e => e.Id);
               
               // 创建非聚集索引，加快 GUID 列连接查询速度
               builder.HasIndex(e => e.UserId).IsUnique().IsClustered(false);
           }
       }
   }
   
   

5. 在 Infrastructure.DbEntityConfigs 目录下新建 ApplicationDbContext EF Core 数据库上下文

   using CampusServicePlatform.Model.DbEntities;
   using Microsoft.Asp***Core.Identity.EntityFrameworkCore;
   using Microsoft.EntityFrameworkCore;
   
   namespace CampusServicePlatform.Infrastructure.DbEntityConfigs
   {
       public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, Guid>
       {
           public virtual DbSet<UserInfo> UserInfos { get; set; }
   
           public ApplicationDbContext() { }
   
           public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
           {
           }
   
           protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
           {
               if (!optionsBuilder.IsConfigured)
               {
                   optionsBuilder.UseSqlServer("本地数据库连接字符串");
               }
           }
   
           protected override void OnModelCreating(ModelBuilder modelBuilder)
           {
               base.OnModelCreating(modelBuilder);
               modelBuilder.ApplyConfigurationsFromAssembly(GetType().Assembly);
           }
       }
   }
   
   

6. 在 WebAPI.Program.cs 中配置 DbContext 与 Identity

   此处的数据库连接字符串获取不再赘述，详情请移步另一篇文章查看：https://blog.csdn.***/Felix61Felix/article/details/134634047。

   var builder = WebApplication.CreateBuilder(args);
   
   // ...
   
   builder.Services.AddDbContext<ApplicationDbContext>(options =>
   {
       string? connectionString = builder.Configuration.GetConnectionString("Default");
       options.UseSqlServer(connectionString);
   });
   
   builder.Services
       .AddIdentity<ApplicationUser, ApplicationRole>(options =>
       {
           // 在这里仅要求简单的限制，即密码长度为 6，其他限制请自行配置
           options.Password.RequiredLength = 6;
           options.Password.RequireDigit = false;
           options.Password.RequireLowercase = false;
           options.Password.RequireUppercase = false;
           options.Password.RequireNonAlphanumeric = false;
       })
       .AddEntityFrameworkStores<ApplicationDbContext>()
       .AddDefaultTokenProviders();
   
   // ...
   
   var app = builder.Build();
   

7. 进入程序包管理控制台，将解决方案的启动项目、程序包管理控制台的默认项目都切换成 Infrastructure

8. 在程序包管理控制台中依次输入 EF Core 迁移命令：Add-Migration InitialCreate -OutputDir DatabaseEntityConfig/_Migrations、Update-database，以生成数据库

JWT

1. 在 Infrastructure 层中新建 JwtHelper 类

   using CampusServicePlatform.Model.DbEntities;
   using Microsoft.Asp***Core.Identity;
   using Microsoft.Extensions.Configuration;
   using Microsoft.IdentityModel.Tokens;
   using System.IdentityModel.Tokens.Jwt;
   using System.Security.Claims;
   using System.Text;
   
   namespace CampusServicePlatform.Infrastructure
   {
       public class JwtHelper
       {
           private readonly IConfiguration _configuration;
           private readonly UserManager<ApplicationUser> _userManager;
   
           public JwtHelper(IConfiguration configuration, UserManager<ApplicationUser> userManager)
           {
               _configuration = configuration;
               _userManager = userManager;
           }
   
           public string GenerateJwtToken(ApplicationUser? user, UserInfo? userInfo, IList<string>? roles)
           {
               var claims = new List<Claim>
               {
                   new Claim(ClaimTypes.Name, user.UserName),
                   new Claim("avatar", userInfo.Avatar),
                   new Claim("nickname", userInfo.Nickname)
               };
   
               foreach (var role in roles)
               {
                   claims.Add(new Claim(ClaimTypes.Role, role));
               }
   
               var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration.GetSection("Jwt:Key").Value));
   
               var signingCredentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256Signature);
   
               var jwtSecurityToken = new JwtSecurityToken(
                   claims: claims,
                   // 过期时间，单位是“分”
                   expires: DateTime.Now.AddMinutes(60 * 24 * 7),
                   notBefore: DateTime.Now,
                   issuer: _configuration.GetSection("Jwt:Issuer").Value,
                   audience: _configuration.GetSection("Jwt:Audience").Value,
                   signingCredentials: signingCredentials
                   );
   
               var jwtToken = new JwtSecurityTokenHandler().WriteToken(jwtSecurityToken);
               return jwtToken;
           }
   
           public async Task<bool> CheckJwtToken(string? jwtToken)
           {
               var jwtTokenHandler = new JwtSecurityTokenHandler();
   
               var issuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_configuration.GetSection("Jwt:Key").Value));
   
               var validationParameters = new TokenValidationParameters
               {
                   ValidateIssuerSigningKey = true,
                   IssuerSigningKey = issuerSigningKey,
                   ValidateIssuer = true,
                   ValidIssuer = _configuration.GetSection("Jwt:Issuer").Value,
                   ValidateAudience = true,
                   ValidAudience = _configuration.GetSection("Jwt:Audience").Value,
                   ClockSkew = TimeSpan.Zero
               };
   
               var principal = jwtTokenHandler.ValidateToken(jwtToken, validationParameters, out var securityToken);
               if (principal.Identity?.IsAuthenticated != true)
               {
                   return false;
               }
   
               return true;
           }
       }
   }
   

2. 在 WebAPI 层中编写 JWT 的配置文件

   {
     "Jwt": {
       "Key": "自行设置密钥，推荐写 GUID 值",
       "Issuer": "签发者，推荐写 API 地址",
       "Audience": "接收者，推荐写前端地址"
     }
   }
   

3. 在 WebAPI.Program.cs 中配置 JWT

   var builder = WebApplication.CreateBuilder(args);
   
   // ...
   
   builder.Services
       .AddAuthentication(options =>
       {
           options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
           options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
       })
       .AddJwtBearer(options =>
       {
           options.TokenValidationParameters = new TokenValidationParameters
           {
               ValidateActor = true,
               ValidateIssuer = true,
               ValidateAudience = true,
               RequireExpirationTime = true,
               ValidateIssuerSigningKey = true,
               ValidIssuer = builder.Configuration.GetSection("Jwt:Issuer").Value,
               ValidAudience = builder.Configuration.GetSection("Jwt:Audience").Value,
               IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(builder.Configuration.GetSection("Jwt:Key").Value))
           };
       });
   
   builder.Services.AddScoped<JwtHelper>();
   
   // ...
   
   var app = builder.Build();
   

Service

1. 在 Service 层新建 IA***ountService 接口

   using CampusServicePlatform.Model.DTO;
   
   namespace CampusServicePlatform.Service
   {
       public interface IA***ountervice
       {
           Task<bool> CheckJwtToken(string? jwtToken);
           Task<string?> SignIn(UserRequest userRequest);
           Task<bool> SingUp(UserRequest userRequest);
       }
   }
   

2. 在 Service 层新建 A***ountService 实现类

   using CampusServicePlatform.Infrastructure;
   using CampusServicePlatform.Infrastructure.DbEntityConfigs;
   using CampusServicePlatform.Model.DbEntities;
   using CampusServicePlatform.Model.DTO;
   using CampusServicePlatform.Model.Enum;
   using Microsoft.Asp***Core.Identity;
   using Microsoft.EntityFrameworkCore;
   
   namespace CampusServicePlatform.Service
   {
       public class A***ountService : IA***ountervice
       {
           private readonly ApplicationDbContext _context;
           private readonly UserManager<ApplicationUser> _userManager;
           private readonly RoleManager<ApplicationRole> _roleManager;
           private readonly JwtHelper _jwtHelper;
           private readonly StringHelper _stringHelper;
   
           public A***ountService(ApplicationDbContext context, UserManager<ApplicationUser> userManager, RoleManager<ApplicationRole> roleManager, JwtHelper jwtHelper, StringHelper stringHelper)
           {
               _context = context;
               _userManager = userManager;
               _roleManager = roleManager;
               _jwtHelper = jwtHelper;
               _stringHelper = stringHelper;
           }
   
           public async Task<bool> SingUp(UserRequest userRequest)
           {
               var user = new ApplicationUser
               {
                   UserName = userRequest.UserName
               };
   
               var result = await _userManager.CreateAsync(user, userRequest.Password);
               if (!result.Su***eeded)
               {
                   throw new ApplicationException(_stringHelper.ListItemToString(result.Errors, "Description"));
               }
   
               if (userRequest.Roles.Count == 0)
               {
                   userRequest.Roles.Add(RoleEnum.Normal.ToString());
               }
               result = await _userManager.AddToRolesAsync(user, userRequest.Roles);
               if (!result.Su***eeded)
               {
                   throw new ApplicationException(_stringHelper.ListItemToString(result.Errors, "Description"));
               }
   
               var userInfo = new UserInfo
               {
                   UserId = user.Id,
                   Avatar = "favicon.ico",
                   Nickname = user.UserName,
                   CreatedTime = DateTime.Now,
               };
               _context.UserInfos.Add(userInfo);
               await _context.SaveChangesAsync();
   
               return true;
           }
   
           public async Task<string?> SignIn(UserRequest userRequest)
           {
               var user = await _userManager.FindByNameAsync(userRequest.UserName);
               if (user == null)
               {
                   throw new KeyNotFoundException("用户名或密码错误");
               }
   
               var result = await _userManager.CheckPasswordAsync(user, userRequest.Password);
               if (!result)
               {
                   throw new KeyNotFoundException("用户名或密码错误");
               }
   
               var userInfo = await _context.UserInfos.SingleOrDefaultAsync(e => e.UserId == user.Id);
               var roles = await _userManager.GetRolesAsync(user);
   
               var jwtToken = _jwtHelper.GenerateJwtToken(user, userInfo, roles);
   
               return jwtToken;
           }
   
           public Task<bool> CheckJwtToken(string? jwtToken)
           {
               return _jwtHelper.CheckJwtToken(jwtToken);
           }
       }
   }
   

3. 在 Infrastructure 层新建 StringHelper 辅助类

   namespace CampusServicePlatform.Infrastructure
   {
       public class StringHelper
       {
           public string ListItemToString<T>(IEnumerable<T> collection, string? propertyName = null)
           {
               if (collection == null)
               {
                   throw new ArgumentNullException(nameof(collection));
               }
   
               if (string.IsNullOrEmpty(propertyName))
               {
                   if (typeof(T) == typeof(string))
                   {
                       return string.Join("；", collection.Cast<string>());
                   }
                   else
                   {
                       throw new ArgumentException("属性名不能为空", nameof(propertyName));
                   }
               }
   
               var property = typeof(T).GetProperty(propertyName);
   
               if (property == null)
               {
                   throw new ArgumentException($"对象不存在名为 {propertyName} 的属性");
               }
   
               return string.Join("；", collection.Select(item => property.GetValue(item)));
           }
       }
   }
   

4. 在 WebAPI.Program.cs 中注入 Service 和辅助类

   var builder = WebApplication.CreateBuilder(args);
   
   // 3...
   
   builder.Services.AddScoped<StringHelper>();
   builder.Services.AddScoped<IA***ountervice, A***ountService>();
   
   // ...
   
   var app = builder.Build();
   

Web API

1. 在 WebAPI.Controllers 目录下新建 A***ountController 控制器

   using CampusServicePlatform.Model.Attributes;
   using CampusServicePlatform.Model.DTO;
   using CampusServicePlatform.Service;
   using Microsoft.Asp***Core.Authorization;
   using Microsoft.Asp***Core.Mvc;
   
   namespace CampusServicePlatform.WebAPI.Controllers
   {
       [Route("api/[controller]")]
       [ApiController]
       public class A***ountController : ControllerBase
       {
           private readonly IA***ountervice _a***ountService;
   
           public A***ountController(IA***ountervice a***ountService)
           {
               _a***ountService = a***ountService;
           }
   
           [HttpPost("sign-up")]
           [Transactional]
           public async Task<IActionResult> SignUp(UserRequest userRequest)
           {
               await _a***ountService.SingUp(userRequest);
   
               return Ok(new ApiResponse
               {
                   Message = "注册成功"
               });
           }
   
           [HttpPost("sign-in")]
           public async Task<IActionResult> SignIn(UserRequest userRequest)
           {
               var jwtToken = await _a***ountService.SignIn(userRequest);
   
               return Ok(new ApiResponse
               {
                   Message = "登录成功",
                   Data = new
                   {
                       JwtToken = jwtToken
                   }
               });
           }
   
           [HttpGet("check-jwt-token")]
           [Authorize]
           public async Task<IActionResult> CheckJwtToken()
           {
               var jwtToken = HttpContext.Request.Headers["Authorization"].ToString().Substring("Bearer ".Length).Trim();
   
               var result = await _a***ountService.CheckJwtToken(jwtToken);
               if (!result)
               {
                   throw new ApplicationException("无效的Token");
               }
   
               return Ok(new ApiResponse
               {
                   Message = "Token验证成功"
               });
           }
       }
   }
   

2. 在 Model.DTO 目录下新建 ApiResponse、UserRequest 数据传输类

   namespace CampusServicePlatform.Model.DTO
   {
