Microsoft.AspNet.Identity vnext中的UserValidator

问题描述

我有一个问题，在使用microsoft.aspnet.identity时，我不能使用电子邮件地址作为用户名(创建新项目时选择的个人用户帐户-asp.net 5的默认mvc项目模板).我在很多地方都读过这是解决方案:

I have a problem where I cant use email addresses as usernames when using microsoft.aspnet.identity (Individual user accounts selected when creating new project - default mvc project template for asp.net 5). I have read in many places that this is the solution:

UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager) { AllowOnlyAlphanumericUserNames = false };

但是在新版本的asp.net身份中，UserManager似乎没有名为UserValidator的属性.可以识别"UserValidator"，但是我想现在它以不同的方式添加到了UserManager中.我在UserManager上看不到任何相关属性.

But in the new version of asp.net identity, UserManager doesnt seem to have a property called UserValidator. The "UserValidator" is recognised but I suppose its added to the UserManager in a different way now. I cant see any relevant property on UserManager.

github仓库中针对"Identity"的单元测试对此情况进行了测试.当前是此文件中的最后一个:

The unit tests in the github repo for "Identity" has a test for this case. Its currently the last one in this file:

https://github.com. com/aspnet/Identity/blob/dev/test/Microsoft.AspNet.Identity.Test/UserValidatorTest.cs

我想这应该为答案提供一个线索，但我看不到代码中的内容.

I guess this should give a clue as to the answer but I cant see where this would go in my code.

    [Theory]
    [InlineData("[e-mail]", true)]
    [InlineData("hao", true)]
    [InlineData("test123", true)]
    [InlineData("!noway", true)]
    [InlineData("foo@boz#.com", true)]
    public async Task CanAllowNonAlphaNumericUserName(string userName, bool expectSuccess)
    {
        // Setup
        var manager = MockHelpers.TestUserManager(new NoopUserStore());
        manager.Options.User.UserNameValidationRegex = null;
        var validator = new UserValidator<TestUser>();
        var user = new TestUser {UserName = userName};

        // Act
        var result = await validator.ValidateAsync(manager, user);

        // Assert
        if (expectSuccess)
        {
            IdentityResultAssert.IsSuccess(result);
        }
        else
        {
            IdentityResultAssert.IsFailure(result);
        }
    }

推荐答案

在Startup类的ConfigureServices方法中，AddIdentity方法具有重载，允许重配置不同的选项.

In the ConfigureServices method of the Startup class, the AddIdentity method has an overload which allows different options to be configured.

// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

将其更改为以下内容，可以将电子邮件地址用作用户名.

Changing it to the below allows an email address to be used for usernames.

// Add Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>(options => { options.User.UserNameValidationRegex = null; })
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();
