• در دیالوگ جدید ASP.NET گزینه Empty را انتخاب کنید.

دقت کنید که دکمه Change Authentication غیرفعال است و هیچ پشتیبانی ای برای احراز هویت در این قالب پروژه وجود ندارد.

افزودن پکیج‌های ASP.NET Identity به پروژه

دقت کنید که نصب کردن این پکیج وابستگی‌ها را نیز بصورت خودکار نصب می‌کند: Entity Framework و ASP.NET Idenity Core.

افزودن فرم‌های وب لازم برای ثبت نام کاربران

در دیالوگ باز شده نام فرم را به Register تغییر داده و تایید کنید.

فایل ایجاد شده جدید را باز کرده و کد Markup آن را با قطعه کد زیر جایگزین کنید.

این تنها یک نسخه ساده شده Register.aspx است که از چند فیلد فرم و دکمه ای برای ارسال آنها به سرور استفاده می‌کند.

فایل کد این فرم را باز کرده و محتویات آن را با قطعه کد زیر جایگزین کنید.

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
using System;
using System.Linq;

namespace WebFormsIdentity
{
   public partial class Register : System.Web.UI.Page
   {
      protected void CreateUser_Click(object sender, EventArgs e)
      {
         // Default UserStore constructor uses the default connection string named: DefaultConnection
         var userStore = new UserStore<IdentityUser>();
         var manager = new UserManager<IdentityUser>(userStore);

         var user = new IdentityUser() { UserName = UserName.Text };
         IdentityResult result = manager.Create(user, Password.Text);

         if (result.Succeeded)
         {
            StatusMessage.Text = string.Format("User {0} was created successfully!", user.UserName);
         }
         else
         {
            StatusMessage.Text = result.Errors.FirstOrDefault();
         }
      }
   }
}

کد این فرم نیز نسخه ای ساده شده است. فایلی که بصورت خودکار توسط VS برای شما ایجاد می‌شود متفاوت است.

کلاس IdentityUser پیاده سازی پیش فرض EntityFramework از قرارداد IUser است. قرارداد IUser تعریفات حداقلی یک کاربر در ASP.NET Identity Core را در بر می‌گیرد.

کلاس UserStore پیاده سازی پیش فرض EF از یک فروشگاه کاربر (user store) است. این کلاس چند قرارداد اساسی ASP.NET Identity Core را پیاده سازی می‌کند: IUserStore, IUserLoginStore, IUserClaimStore و IUserRoleStore.

کلاس UserManager دسترسی به API‌های مربوط به کاربران را فراهم می‌کند. این کلاس تمامی تغییرات را بصورت خودکار در UserStore ذخیره می‌کند.

کلاس IdentityResult نتیجه یک عملیات هویتی را معرفی می‌کند (identity operations).

پوشه App_Data را به پروژه خود اضافه کنید.

فایل Web.config پروژه را باز کنید و رشته اتصال جدیدی برای دیتابیس اطلاعات کاربران اضافه کنید. این دیتابیس در زمان اجرا (runtime) بصورت خودکار توسط EF ساخته می‌شود. این رشته اتصال شبیه به رشته اتصالی است که هنگام ایجاد پروژه بصورت خودکار برای شما تنظیم می‌شود.

همانطور که مشاهده می‌کنید نام این رشته اتصال DefaultConnection است.

روی فایل Register.aspx کلیک راست کنید و گزینه Set As Start Page را انتخاب کنید. اپلیکیشن خود را با کلیدهای ترکیبی Ctrl + F5 اجرا کنید که تمام پروژه را کامپایل نیز خواهد کرد. یک نام کاربری و کلمه عبور وارد کنید و روی Register کلیک کنید.

ASP.NET Identity از اعتبارسنجی نیز پشتیبانی می‌کند، مثلا در این مرحله می‌توانید از اعتبارسنج هایی که توسط ASP.NET Identity Core عرضه می‌شوند برای کنترل رفتار فیلد‌های نام کاربری و کلمه عبور استفاده کنید. اعتبارسنج پیش فرض کاربران (User) که UserValidator نام دارد خاصیتی با نام AllowOnlyAlphanumericUserNames دارد که مقدار پیش فرضش هم true است. اعتبارسنج پیش فرض کلمه عبور (MinimumLengthValidator) اطمینان حاصل می‌کند که کلمه عبور حداقل 6 کاراکتر باشد. این اعتبارسنج‌ها بصورت property‌ها در کلاس UserManager تعریف شده اند و می‌توانید آنها را overwrite کنید و اعتبارسنجی سفارشی خود را پیاده کنید. از آنجا که الگوی دیتابیس سیستم عضویت توسط Entity Framework مدیریت می‌شود، روی الگوی دیتابیس کنترل کامل دارید، پس از Data Annotations نیز می‌توانید استفاده کنید.
