DI注册服务类型.net core 3.0

本文介绍了DI注册服务类型 core 3.0的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个n层分层的应用程序，并且在基础结构模块中，我试图开发发送电子邮件以确认用户的程序，但出现错误。

I have one n-tier layered app and in Infrastructure module where I'm trying to develop sending email for confirmation an user, I'm getting an error.

没有类型的服务'IMS.Infrastructure.Helpers.CustomEmailConfirmationTokenProvider`1 [Microsoft.AspNetCore.Identity.IdentityUser]'已注册。

No service for type 'IMS.Infrastructure.Helpers.CustomEmailConfirmationTokenProvider`1[Microsoft.AspNetCore.Identity.IdentityUser]' has been registered.

根据代码，我接下来要做的是：

From code what I had did is next:

public class CustomEmailConfirmationTokenProvider<TUser> : DataProtectorTokenProvider<TUser> where TUser : class { public CustomEmailConfirmationTokenProvider(IDataProtectionProvider dataProtectionProvider, IOptions<DataProtectionTokenProviderOptions> options, ILogger<DataProtectorTokenProvider<TUser>> logger) : base(dataProtectionProvider, options) { } }

并用于创建服务：

services.AddDbContext<ApplicationIdentityDbContext>(options => options.UseSqlServer(configuration.GetConnectionString("Default"))); services.AddIdentityCore<ApplicationUser>(options => { options.Password.RequireDigit = false; options.Password.RequireLowercase = false; options.Password.RequireNonAlphanumeric = false; options.Password.RequireUppercase = false; options.Password.RequiredLength = 4; options.SignIn.RequireConfirmedEmail = true; options.Tokens.ProviderMap.Add("CustomEmailConfirmation", new TokenProviderDescriptor( typeof(CustomEmailConfirmationTokenProvider<IdentityUser>))); options.Tokens.EmailConfirmationTokenProvider = "CustomEmailConfirmation"; }) .AddEntityFrameworkStores<ApplicationIdentityDbContext>(); services.AddTransient<CustomEmailConfirmationTokenProvider<ApplicationUser>>(o => { var service = new CustomEmailConfirmationTokenProvider<ApplicationUser>(o.GetService<IDataProtectionProvider>(), o.GetService<IOptions<DataProtectionTokenProviderOptions>>(), o.GetService<ILogger<DataProtectorTokenProvider<ApplicationUser>>>()); return service; });

我将需要帮助来了解如何未注册CustomEmailConfirmationTokenProvider服务，我做错了什么？

I will need help to understand how service CustomEmailConfirmationTokenProvider is not registered, what I had did wrong ?

亲切的问候， Danijel

推荐答案

容器 CustomEmailConfirmationTokenProvider< ApplicationUser> 和 CustomEmailConfirmationTokenProvider< IdentityUser> 是两个不同且不相关的类。

From perspective of IoC container CustomEmailConfirmationTokenProvider<ApplicationUser> and CustomEmailConfirmationTokenProvider<IdentityUser> are two different and unrelated classes.

您应该同时具有使用和注册权限，才能拥有相同类型的用户。

You should have both usage and registration to have same type of user.
