Question

我想在Stormpath中注册后将新用户添加到我的本地数据库。在文档https://docs.stormpath.com/dotnet/aspnetcore/latest/registration.html#registration中有关于注册后处理程序的部分。我有问题因为我无法在StartUp文件中使用UserRepository。我有错误：

无法解析类型的服务尝试时'AppProject.Repositories.IUserRepository' 激活'AppProject.Startup'

    public void ConfigureServices(IServiceCollection services, IUserRepository userRepository)
            {
    services.AddStormpath(new StormpathOptions()
               {
                Configuration = new StormpathConfiguration()
                {
                    Client = new ClientConfiguration()
                    {
                        ApiKey = new ClientApiKeyConfiguration()
                        {
                            Id = "xxxxxxxxxxx",
                            Secret = "xxxxxxxxx"
                        }
                    }
                },
                PostRegistrationHandler = (context, ct) =>
               {
                   return MyPostRegistrationHandler(context, ct, userRepository);
               }
            });
}



   private Task MyPostRegistrationHandler(PostRegistrationContext context, CancellationToken ct, IUserRepository userRepository)
        {
            userRepository.Add(new User(context.Account.Email, context.Account.FullName, context.Account.GivenName, context.Account.Surname, context.Account.Username));
            userRepository.SaveChangesAsync();
            return Task.FromResult(0);
        }

在这种情况下，我认为它不能解决StartUp中IUserRepository的依赖性。你可以尝试这样的事情。

1）添加扩展方法。

public static IServiceProvider AddServices(this IServiceCollection services)
{
    services.AddTransient<IUserRepository, UserRepository>();
    // rest of the things.
    return services.BuildServiceProvider();
}

2）获取类似这样的userRepository实例。

   IServiceCollection services = new ServiceCollection();
   services.AddServices();
   var provider = services.BuildServiceProvider();
   var userRepository = provider.GetRequiredService<IUserRepository>();

ConfigurationServices将没有IUserRepository输入参数。
