ASP.NET Core中的密码重置令牌提供程序-找不到IUserTokenProvider

问题描述：

你好，

我对Google进行了详尽的搜索，但是有来自ASP.NET的数百个示例，但与ASP.NET Core无关.

I googled thoroughly but there is hundred examples from ASP.NET but nothing about ASP.NET Core.

为了进行密码重置工作，我需要将IUserTokenProvider实例注册到DI中.

In order to getting password reset work I need to register an IUserTokenProvider instance into DI.

没有它，我在下面的行出现异常:

Without it I get exception at following line:

var result = await _userManager.ResetPasswordAsync(user, token, password);

例外

"No IUserTokenProvider named 'PasswordResetTokenProvider' is registered."

这很有意义，所以我尝试在DI中注册它:

That makes sense so I tried to register it in the DI:

services.AddSingleton<IUserTokenProvider<User>, DataProtectorTokenProvider<User>>();

但是接口 IUserTokenProvider 不存在.我在文件中使用了 Microsoft.AspNetCore.Identity .它甚至在项目gitlab中都不存在.

But the interface IUserTokenProvider does not exists. I'm using Microsoft.AspNetCore.Identity in the file. It even does not exists in project gitlab.

好吧，在挖掘身份源代码后，我发现了一个相似接口 IUserTwoFactorTokenProvider< T> .让我们改用它:

Well, after digging in identity source code I find a similar interface IUserTwoFactorTokenProvider<T>. Let's use this instead:

services.AddSingleton<IUserTwoFactorTokenProvider<User>, DataProtectorTokenProvider<User>>();

...也没有运气.

TL; DR:

请-如何在ASP.NET 核心中重置密码工作?充其量举个例子.

Please - how to get the password reset in ASP.NET Core work? At best with some example.

谢谢.

答

我不确定这是解决方法还是常规方法，但是 IUserTwoFactorTokenProvider 接口似乎是正确的方法.IUserTokenProvider似乎不再存在.

I'm not sure if it's workaround or normal approach, but the IUserTwoFactorTokenProvider interface seems to be a right way. IUserTokenProvider appears to no longer exists.

弄清楚我必须以身份手动注册提供者:

Figured out that I have to register the provider manually in the identity:

services.AddIdentity<User, Role>(options =>
            {
                ...
                options.Tokens.ProviderMap.Add("Default", new TokenProviderDescriptor(typeof(IUserTwoFactorTokenProvider<User>)));
            })

以及 ConfigureServices 中的可选配置:

services.Configure<DataProtectionTokenProviderOptions>(o =>
        {
            o.Name = "Default";
            o.TokenLifespan = TimeSpan.FromHours(1);
        });

并且密码重置/电子邮件验证令牌现在可以正常工作.

And the password reset / email validation tokens are working now.
