44- EF + Identity实现

1-配置EF， 需要创建如下几个类

 默认User主键为guid类型，现在改成int类型

namespace MvcCookieAuthSample.Models
{
    public class ApplicationUser:IdentityUser<int>
    {

    }

namespace MvcCookieAuthSample.Models
{
    public class ApplicationUserRole:IdentityRole<int>
    {
  
    }
}

namespace MvcCookieAuthSample.Data
{
    public class ApplicationDbContext:IdentityDbContext<ApplicationUser,ApplicationUserRole,int>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options):base(options)
        {

        }
    }
}

在Startup.cs 启用EF

    public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(options => {
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
            });
        }

在appsetting.json配置连接数据字符串

"ConnectionStrings": {
    "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=aspnet-IdentitySample-C9275B98-9E63-4E35-AE50-5F96CA59C41D;Trusted_Connection=True;MultipleActiveResultSets=true"
  }

使用Nuget增加   Microsoft.EntityFrameworkCore.Tools

然后在控制台运行相关EF命令生成数据库表，  http://www.siyouku.cn/article/6871.html

E:\coding\netcore\MvcCookieAuthSample>dotnet ef database update

　　

2-启用验证

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(options=> {
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
            });


            services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                .AddCookie(options=>{//自定义登陆地址，不配置的话则默认为http://localhost:5000/Account/Login
                    options.LoginPath="/Account/Login";
                });

            services.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });

            services.AddIdentity<ApplicationUser, ApplicationUserRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

            services.Configure<IdentityOptions>(option=> {
                option.Password.RequireLowercase = false;
                option.Password.RequireNonAlphanumeric = false;
                option.Password.RequireUppercase = false;
            });

            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        }

注册账号

  public class AccountController : Controller
    {
        private UserManager<Models.ApplicationUser> _userManager;
        private SignInManager<Models.ApplicationUser> _signInManager;
        public AccountController(UserManager<Models.ApplicationUser> userManager,
            SignInManager<Models.ApplicationUser> signInManager)
        {
            _signInManager = signInManager;
            _userManager = userManager;
        }

        [HttpPost]
        public async Task<IActionResult> Register(ViewModel.RegisterViewModel registerViewModel)
        {
            Models.ApplicationUser applicationUser = new Models.ApplicationUser()
            {
                Email = registerViewModel.Email,
                UserName = registerViewModel.Email,
                NormalizedEmail = registerViewModel.Email
            };

            IdentityResult result = await _userManager.CreateAsync(applicationUser, registerViewModel.Password);
            if (result.Succeeded)
            {
                return RedirectToAction("Index", "Home");
            }
            return View();
        }


    }
