Question

我使用身份并且无法访问确认页面（没有从注册页面过渡到另一个页面）。使用迁移，我为用户创建了表，但通过单击“注册”按钮，此页面会刷新。

IdentityHostingStartup：

    public void Configure(IWebHostBuilder builder)
    {
        builder.ConfigureServices((context, services) =>
        {
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(context.Configuration.GetConnectionString("AspNetRunConnection")
            ));
        });
    }

注册.cshtml：

@page
@model RegisterModel
@{
    Layout = null;
    ViewData["Title"] = "Register";
}

好像你的注册失败了（可能用户已经存在了），所以返回当前页面而不去确认，而你没有在视图中显示错误信息，所以你不知道帐号注册成功。

将此行添加到您的自定义注册视图以显示错误消息：

<div asp-validation-summary="All" class="text-danger"></div>
