.NET MVC 6/vNext UserValidator允许字母数字字符 [英] .NET MVC 6 / vNext UserValidator to allow alphanumeric characters

问题描述

我想做的只是在.NET MVC 6/vNext注册过程和我所看过的每个教程中允许字母数字字符(即

What I'm trying to do is simply allow alphanumeric characters in the .NET MVC 6 / vNext registration process and every tutorial I've seen (ie Configure Microsoft.AspNet.Identity to allow email address as username) references UserManager.UserValidator, in which is now not available in the current framework.

我已经看到了: Microsoft.AspNet.Identity vnext中的UserValidator 看起来与我的问题相同，但是从那以后他们就把UserNameValidationRegex属性从框架中删除了.很棒.

I've seen this: UserValidator in Microsoft.AspNet.Identity vnext which looks to be the same issue as mine, but they've taken the UserNameValidationRegex property out of the framework since. Brilliant.

services.AddIdentity<ApplicationUser, IdentityRole>(
                o => {
                    o.Password.RequireDigit = false;
                    o.Password.RequireLowercase = false;
                    o.Password.RequireUppercase = false;
                    o.Password.RequireNonLetterOrDigit = false;
                    o.Password.RequiredLength = 2;
                    //o.User.AllowedUserNameCharacters here seems to be the only logical thing I can access
                })
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

我找到了o.User.AllowedUserNameCharacters，但是由于找不到相关文档，我不知道该设置哪种格式?有没有人在同一条船上并且解决了这个问题?

I've found o.User.AllowedUserNameCharacters, but with there being no documentation that I've found on this I've no idea what format I have to set that in? Anyone out there that's in the same boat and worked this out?

谢谢.

推荐答案

我看了 aspnet/身份GitHub存储库，并搜索了您找到的属性(AllowedUserNameCharacters).这就是我所拥有的.

I took a look at the aspnet/Identity GitHub repository and did a search for the property you have found (AllowedUserNameCharacters). Here's what I've got.

来自回购中的UserOptions.cs类: [此处链接]

/// <summary>
/// Gets or sets the list of allowed characters in the username used to validate user names.
/// </summary>
/// <value>
/// The list of allowed characters in the username used to validate user names.
/// </value>
public string AllowedUserNameCharacters { get; set; } = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+";

因此，您似乎需要将此属性设置为"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"(即，从原始设置的字符串的末尾删除符号.这应该可以实现您想要的功能.

So it would seem that you will need to set this property to be "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789" (i.e. remove the symbols from the end of the orginally set string. This should achieve what you want.

关于此更改的原因，根据问题#558，他们正试图摆脱正则表达式以提高安全性.在中此处.

In terms of why this change was made, according to issue #558, they are trying to move away from regular expressions for increased security. Have a look here for the full details.
