ASP.NET Core 2.0中的多个身份 [英] Multiple Identities in ASP.NET Core 2.0
问题描述
我正在将ASP.NET Core 1.0应用程序迁移到ASP.NET Core 2.0.
I am migrating an ASP.NET Core 1.0 application to ASP.NET Core 2.0.
在启动时,我正在配置两个身份:
In my startup I am configuring two identities:
services.AddIdentity<IdentityUser, IdentityRole>(configureIdentity)
.AddDefaultTokenProviders()
.AddUserStore<IdentityUserStore<IdentityUser>>()
.AddRoleStore<IdentityRoleStore<IdentityRole>>();
services.AddIdentity<Customer, CustomerRole>(configureIdentity)
.AddDefaultTokenProviders()
.AddErrorDescriber<CustomerIdentityErrorDescriber>()
.AddUserStore<CustomerStore<Customer>>()
.AddRoleStore<CustomerRoleStore<CustomerRole>>();
这在ASP.NET Core 1.0中工作正常,但失败并出现错误: System.InvalidOperationException:'方案已存在:Identity.Application'在ASP.NET Core 2.0中.
This worked fine in ASP.NET Core 1.0 but fails with the error: System.InvalidOperationException: 'Scheme already exists: Identity.Application' in ASP.NET Core 2.0.
在ASP.NET Core 2.0中,如果我删除了对AddIdentity
的调用之一,则错误消失了.如何迁移代码,以便可以在应用程序中使用两种不同类型的身份用户和角色?还是当我在ASP.NET Core 1.0中编写此书时,只是在理解事情如何工作方面犯了一个根本性的错误?
In ASP.NET Core 2.0, if I remove one of the calls to AddIdentity
the error goes away. How do I migrate my code so that I can use two different types of identity user and role in my application? Or did I just make a fundamental error in understanding how things work back when I wrote this in ASP.NET Core 1.0?
推荐答案
在github上浏览ASP.NET Core源代码后,可以使用以下扩展方法添加第二个标识:
After looking through the ASP.NET Core source code on github, a second identity could be added using this extension method:
using Microsoft.AspNetCore.Identity;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection.Extensions;
using System;
using System.Collections.Generic;
using System.Text;
namespace Whatever
{
public static class IdentityExtensions
{
public static IdentityBuilder AddSecondIdentity<TUser, TRole>(
this IServiceCollection services)
where TUser : class
where TRole : class
{
services.TryAddScoped<IUserValidator<TUser>, UserValidator<TUser>>();
services.TryAddScoped<IPasswordValidator<TUser>, PasswordValidator<TUser>>();
services.TryAddScoped<IPasswordHasher<TUser>, PasswordHasher<TUser>>();
services.TryAddScoped<IRoleValidator<TRole>, RoleValidator<TRole>>();
services.TryAddScoped<ISecurityStampValidator, SecurityStampValidator<TUser>>();
services.TryAddScoped<IUserClaimsPrincipalFactory<TUser>, UserClaimsPrincipalFactory<TUser, TRole>>();
services.TryAddScoped<UserManager<TUser>, AspNetUserManager<TUser>>();
services.TryAddScoped<SignInManager<TUser>, SignInManager<TUser>>();
services.TryAddScoped<RoleManager<TRole>, AspNetRoleManager<TRole>>();
return new IdentityBuilder(typeof(TUser), typeof(TRole), services);
}
}
}
