我在我的 .NET Core 应用程序中使用OpenIddict进行 JWT 令牌身份验证。我已按照本教程进行操作,但现在收到以下错误:

InvalidOperationException: No database provider has been configured for this DbContext. A provider can be configured by overriding the DbContext.OnConfiguring method or by using AddDbContext on the application service provider...

我的ConfigureServices方法Startup.cs

        public void ConfigureServices(IServiceCollection services)
    {
        var builder = new ConfigurationBuilder()
            .AddJsonFile("appsettings.json");
        Configuration = builder.Build();

        services.AddEntityFrameworkSqlServer()
             .AddDbContext<MyDbContext>(options =>
                 options.UseSqlServer(Configuration["Data:MyDbContext:ConnectionString"]));

        services.AddIdentity<ApplicationUser, ApplicationRole>()
            .AddEntityFrameworkStores<MyDbContext>()
            .AddDefaultTokenProviders()
            .AddOpenIddictCore<Application>(config => config.UseEntityFramework());

        services.AddMvc();

        // for seeding the database with the demo user details
        //services.AddTransient<IDatabaseInitializer, DatabaseInitializer>();
        services.AddScoped<OpenIddictManager<ApplicationUser, Application>, CustomOpenIddictManager>();
    }

不知道该怎么做,因为我无法在使用AddIdentity.

我的连接字符串很好,在添加 OpenIddict 之前一切正常。

更新 这是我的appsettings.json文件:

    {
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Verbose",
      "System": "Information",
      "Microsoft": "Information"
    }
  },
  "Data": {
    "DefaultConnection": {
      "ConnectionString": "my connection string"
    },
    "SaleboatContext": {
      "ConnectionString": "my connection string"
    }
  }
}

我的数据库上下文:

public class ApplicationUser : IdentityUser { }

public partial class MyDbContext : IdentityDbContext<ApplicationUser>
{

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
}

由于 EntityFramework Core RC2 中的设计更改,您现在需要DbContextOptions手动流动或直接在OnModelCreating.

尝试将此构造函数添加到您的数据库上下文中(应该从 派生OpenIddictContext):

public partial class MyDbContext : OpenIddictContext<ApplicationUser> {
    public MyDbContext(DbContextOptions options)
        : base(options) {
    }
}
