.net 6.0 identity实现


这里是用的现在最新的.net 6.0 ,其他版本都差不多,我这里不是在创建项目那里添加身份验证,而是基于没有身份验证后期添加进去的。

可以去官网上面看,都有相关的文档:https://docs.microsoft.com/zh-cn/aspnet/core/security/authentication/identity?view=aspnetcore-6.0&tabs=netcore-cli

1. 引用NUGET包

这里会设计到几个包

Microsoft.AspNetCore.Identity : 包含Identity自带的model类
Microsoft.Extensions.Identity.Stores : 包含了上面Identity的依赖项,新增了UserStore和RoleStore等操作项,我们看源码可以看出来

Microsoft.AspNetCore.Identity.EntityFrameworkCore :包含了上面Stores 的依赖项,还新增了IdentityDbContext的数据库EF操作

由于是包含了依赖项,只需要在Domain实体层引用 efcore这个包就行了

Microsoft.AspNetCore.Identity.EntityFrameworkCore

2. 添加DbContext

Identity自带了一些系统表,所以要生成数据库,基础设置层这里的DbContext要继承Identity提供的IdentityDbContext

3. 添加相关实体,如果不需要扩展Identity系统自带的这些表,可以忽略这一步

 这里只是举了一个例子,如果需要扩展其他数据表,只需要继承相应的Idnetity实体就行了

 3. 注入服务

 我是基于mysql数据库的,mysql相关的依赖项这里就直接忽略了。

 先配置EF DbContext生成数据库

builder.Services.AddDbContext(options =>
{
    var strdb = builder.Configuration.GetSection("dbstr").Value;
    options.UseMySql(strdb, ServerVersion.AutoDetect(strdb), mySqlOptionsAction =>
    {
        mySqlOptionsAction.MigrationsAssembly(typeof(Program).Assembly.GetName().Name);
    });
});

配置 Identity

builder.Services.AddIdentity(options =>
{
    // Password settings.
    options.Password.RequireDigit = true;
    options.Password.RequireLowercase = true;
    options.Password.RequireNonAlphanumeric = true;
    options.Password.RequireUppercase = true;
    options.Password.RequiredLength = 6;
    options.Password.RequiredUniqueChars = 1;

    // Lockout settings.
    options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(5);
    options.Lockout.MaxFailedAccessAttempts = 5;
    options.Lockout.AllowedForNewUsers = true;

    // User settings.
    options.User.AllowedUserNameCharacters =
    "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+";
    options.User.RequireUniqueEmail = false;
})
.AddDefaultTokenProviders()
.AddEntityFrameworkStores();

//配置授权跳转
builder.Services.ConfigureApplicationCookie(cookie =>
{
    cookie.LoginPath = "/Account/FcbLogin/";
    cookie.LogoutPath = "/Account/FcbLoginOut/";
    cookie.AccessDeniedPath = "/Account/FcbError/";
    cookie.ExpireTimeSpan = TimeSpan.FromMinutes(30);
    // cookie.SlidingExpiration = true;
});

顺便提一下,一般授权会注入Authentication,但是idnetity 内部已经调用了AddAuthentication,所以这里不需要调用

 4. 注入管道

在UseAuthorization之前注入UseAuthentication

app.UseAuthentication();

5. 添加授权

添加登入和登出,我这里只是简单测试,只是写了登入相关的东西

        public ActionResult FcbLogin(string ReturnUrl)
        {
            ReturnUrl = ReturnUrl ?? Url.Content("~/");
            ViewBag.ReturnUrl = ReturnUrl;
            return View();
        }
        [HttpPost]
        public async Task Login(UserLogin model)
        {
            var UserLoginInfo = await _userManager.FindByNameAsync(model.UserName);
            if (UserLoginInfo == null)
            {
                var user = new aspnetusers(model.UserName, model.Password);
                var result = await _userManager.CreateAsync(user);
                if (result.Succeeded)
                {
                    _logger.LogInformation("注册成功");
                    Console.WriteLine("注册成功");
                }
                else
                {
                    _logger.LogInformation(String.Join("/r/n", result.Errors));
                    Console.WriteLine(String.Join("/r/n", result.Errors));
                }
            }
            List claimsIdentities = new List();
            AuthenticationProperties properties = new AuthenticationProperties()
            {
                ExpiresUtc = DateTime.UtcNow.AddMinutes(30),
                RedirectUri = model.ReturnUrl
            };
            var customClaims = new List() { new Claim("fcb", "123"), new Claim("username", "范臣斌") };
            await _signInManager.SignInWithClaimsAsync(UserLoginInfo, properties, customClaims);
            if (string.IsNullOrEmpty(model.ReturnUrl))
            {
                return LocalRedirect("/");
            }
            return LocalRedirect(model.ReturnUrl);
        }
        public ActionResult FcbError()
        {
            return View();
        }
        [HttpGet]
        public ActionResult FcbLoginOut()
        {
            _signInManager.SignOutAsync();
            return Ok();
        }

最后在需要授权的地方打上标签就行了,流程就完了

最后再测试一下访问有授权标签的 /Home/Index ,会自动跳到 /Account/FcbLogin/登录页

 

 Perfect !!!
