【问题描述】：

第一次尝试添加迁移时发生此错误。我已经添加了扩展方法和我的服务类

public void ConfigureServices(IServiceCollection 服务)

        services.AddCors();
        services.AddControllers();
        
        services.Configure<AppSettings>(AppSettings);
        services.ConfigureJWT(Configuration);
        services.ConfigureIdentity();
        services.AddScoped<ILoginService, LoginService>();
        services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>, CustomClaimPrincipalFactory>();
    

public static void ConfigureIdentity(这个IServiceCollection服务)

        var builder = services.AddIdentityCore<ApplicationUser>(o =>
        
            o.Password.RequireDigit = true;
            o.Password.RequireLowercase = false;
            o.Password.RequireUppercase = false;
            o.Password.RequireNonAlphanumeric = false;
            o.Password.RequiredLength = 6;
            o.User.RequireUniqueEmail = true;
        );
        builder = new IdentityBuilder(builder.UserType, typeof(IdentityRole),
       builder.Services);
        builder.AddEntityFrameworkStores<AuthDBContext>()
        .AddDefaultTokenProviders();


    

公共类 CustomClaimPrincipalFactory : UserClaimsPrincipalFactory

    public CustomClaimPrincipalFactory(
        UserManager<ApplicationUser> userManager,
        RoleManager<IdentityRole> roleManager,
        IOptions<IdentityOptions> optionsAccessor)
        : base(userManager, roleManager, optionsAccessor)
    
    

    protected override async Task<ClaimsIdentity> GenerateClaimsAsync(ApplicationUser user)
    
        ClaimsIdentity identity = await base.GenerateClaimsAsync(user);
        identity.AddClaim(new Claim("ServiceSite", user.ServiceSite ?? ""));
        return identity;
    

这里又是错误

访问 Microsoft.Extensions.Hosting 服务时出错。在没有应用程序服务提供商的情况下继续。错误：无法构造某些服务（验证服务描述符“ServiceType：Microsoft.AspNetCore.Identity.IUserClaimsPrincipalFactory1[AuthenticationService.Entities.ApplicationUser] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.UserClaimsPrincipalFactory1[AuthenticationService.Entities.ApplicationUser]”时出错：无法解析“AuthenticationService.Data”类型的服务.AuthDBContext 尝试激活 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore9[AuthenticationService.Entities.ApplicationUser,Microsoft.AspNetCore.Identity.IdentityRole,AuthenticationService.Data.AuthDBContext,System.String,Microsoft.AspNetCore.Identity.IdentityUserClaim1[System.String],Microsoft.AspNetCore.Identity.IdentityUserRole1[System.String],Microsoft.AspNetCore.Identity.IdentityUserLogin1[System.String],Microsoft.AspNetCore.Identity。 IdentityUserToken1[System.String],Microsoft.AspNetCore.Identity.IdentityRoleClaim1[System.String]]'。）（验证服务描述符“ServiceType：Microsoft.AspNetCore.Identity.UserManager1[AuthenticationService.Entities.ApplicationUser] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.UserManager1[AuthenticationService.Entities.ApplicationUser]”时出错：无法解析服务类型'AuthenticationService.Data.AuthDBContext' 尝试激活 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore9[AuthenticationService.Entities.ApplicationUser,Microsoft.AspNetCore.Identity.IdentityRole,AuthenticationService.Data.AuthDBContext,System.String,Microsoft.AspNetCore.Identity.IdentityUserClaim1[System.String],Microsoft.AspNetCore.Identity.IdentityUserRole1[System.String],Microsoft.AspNetCore.Identity.IdentityUserLogin1[ System.String],Microsoft.AspNetCore.Identity.IdentityUserToken1[System.String],Microsoft.AspNetCore.Identity.IdentityRoleClaim1[System.String]]'。）（验证服务描述符时出错'ServiceType: Microsoft.AspNetCore.Identity.IUserStore1[AuthenticationService.Entities.ApplicationUser] Lifetime: Scoped ImplementationType: Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore9[AuthenticationService.Entities .ApplicationUser,Microsoft.AspNetCore.Identity.IdentityRole,AuthenticationService.Data.AuthDBContext,System.String,Microsoft.AspNetCore.Identity.IdentityUserClaim1[System.String],Microsoft.AspNetCore.Identity.IdentityUserRole1[System.String],Microsoft.AspNetCore.Identity.IdentityUserLogin1[System.String],Microsoft.AspNetCore.Identity.IdentityUserToken1[ System.String],Microsoft.AspNetCore.Identity.IdentityRoleClaim1[System.String]]': Unable to resolve service for type 'AuthenticationService.Data.AuthDBContext' while attempting to activate 'Microsoft.AspNetCore.Identity.EntityFrameworkCore.UserStore9[AuthenticationService.Entities.ApplicationUser,Microsoft.AspNetCore.Identity.IdentityRole,AuthenticationService.Data.AuthDBContext,System.String,Microsoft.AspNetCore.Identity.IdentityUserClaim@987654338 @1[System.String],Microsoft.AspNetCore.Identity.IdentityUserLogin1[System.String],Microsoft.AspNetCore.Identity.IdentityUserToken1[System.String],Microsoft.AspNetCore.Identity.IdentityRoleClaim1[System.String]]'.)

【参考方案1】：

在配置身份存储之前注册 dbcontext

services.AddDbContext<AuthDBContext>();
services.AddIdentity<IdentityUser,IdentityRole>()
                .AddEntityFrameworkStores<AuthDBContext>()
                .AddDefaultTokenProviders();

【讨论】：

如果没有 dbcontext 怎么办？喜欢使用 dapper 而不是实体框架？

我和@symbiont 有同样的查询

这些将需要一些研究，因为 dapper 是另一个用例。如果我能够在这方面取得任何有意义的进展，将分享对此的更新。
