问题描述

我已将我的注册操作方法更改为接受用户名而不是电子邮件.

I have changed my Register Action Method to accept user Name instead of Email.

if (ModelState.IsValid)
{
    var user = new ApplicationUser 
    {
        UserName = model.Name,
        Email = model.Email,
    };

但是当我在文本框中输入名称时，例如 Joe Smith .它给我一个错误，提示无效的用户名.它不允许用户名接受空白.我的问题是如何修改内置用户名以允许空格和特殊字符.我正在使用ASP.NET Core.

But when I Enter Name in TextBox like Joe Smith It give me an error that is Invalid UserName. It is not allowing user Name to Accept White space. My Question is how can I modify the builtin User Name to allow space and special characters. I am using ASP.NET Core.

预先感谢.

推荐答案

您可以在Startup.cs中设置用于配置身份的用户验证规则.

You can set user validation rules configuring identity with options in your Startup.cs.

services.AddIdentity<ApplicationUser, IdentityRole>(options => {
    options.User.AllowedUserNameCharacters = "allowed characters here";
    options.User.RequireUniqueEmail = true/false;
});
