我们基于之前的MvcCookieAuthSample来做开发
MvcCookieAuthSample下载地址:https://files.cnblogs.com/files/wyt007/ASPNETCore%E5%BF%AB%E9%80%9F%E5%85%A5%E9%97%A8.rar

给网站设置默认地址 http://localhost:5000
首先,我们将之前写的系统的Identity注释掉,在Startup.cs中
第一步:添加Nuget包:IdentityServer4
我们可以在vscode中使用ctrl+P键来打开命令面板。然后输入nuget按回车,输入identityserver4后按回车来选择版本进行安装
第二步:添加Config.cs配置类
我们接下来添加一个Config.cs类,这个类是用来初始化IdentityServer的
using System.Collections;
using System.Collections.Generic;
using IdentityServer4;
using IdentityServer4.Models;
using IdentityServer4.Test; namespace MvcCookieAuthSample
{
public class Config
{
//所有可以访问的Resource
public static IEnumerable<ApiResource> GetApiResources()
{
return new List<ApiResource>
{
new ApiResource("api1","API Application")
};
} //客户端
public static IEnumerable<Client> GetClients()
{
return new List<Client>
{
new Client()
{
ClientId="mvc",
AllowedGrantTypes= GrantTypes.Implicit,//模式:最简单的模式
ClientSecrets={//私钥
new Secret("secret".Sha256())
},
AllowedScopes={//可以访问的Resource
IdentityServerConstants.StandardScopes.Profile,
IdentityServerConstants.StandardScopes.OpenId,
},
RedirectUris={"http://localhost:5001/signin-oidc"},//跳转登录到的客户端的地址
PostLogoutRedirectUris={"http://localhost:5001/signout-callback-oidc"},//跳转登出到的客户端的地址
RequireConsent=false//是否需要用户点击确认进行跳转
}
};
} //测试用户
public static List<TestUser> GetTestUsers()
{
return new List<TestUser>{
new TestUser{
SubjectId="",
Username="wyt",
Password="password"
}
};
} //定义系统中的资源
public static IEnumerable<IdentityResource> GetIdentityResources()
{
return new List<IdentityResource>
{
new IdentityResources.OpenId(),
new IdentityResources.Profile(),
new IdentityResources.Email()
};
} }
}
以上使用IdentityServer4测试数据类添加数据,直接存在内存中。IdentityServer4 是支持持久化。
第三步:添加Startup配置
引用命名空间:
using IdentityServer4;
然后打开Startup.cs 加入如下:
services.AddIdentityServer()
.AddDeveloperSigningCredential()//添加开发人员签名凭据
.AddInMemoryApiResources(Config.GetApiResources())//添加内存apiresource
.AddInMemoryClients(Config.GetClients())//添加内存client
.AddInMemoryIdentityResources(Config.GetIdentityResources())//添加系统中的资源
.AddTestUsers(Config.GetTestUsers());//添加测试用户
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
...
//app.UseAuthentication();
app.UseIdentityServer();
...
接着安装UI,UI部分也可以自己编写,也就是登录 注销 允许和错误。
可以到 https://github.com/IdentityServer/IdentityServer4.Quickstart.UI/tree/release 下载,然后解压到项目目录下。
也可以使用命令提示符快速安装:
powershell iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/IdentityServer/IdentityServer4.Quickstart.UI/release/get.ps1'))
在项目目录下打开命令提示符,输入以上命令。
更多信息,可以查看官方readme:https://github.com/IdentityServer/IdentityServer4.Quickstart.UI/blob/release/README.md

修改LoginViewModel,将Email改为UserName,并修改强类型视图的引用部分Login.cshtml
namespace MvcCookieAuthSample.ViewModels
{
public class LoginViewModel
{
//[Required]//必须的
//[DataType(DataType.EmailAddress)]//内容检查是否为邮箱
//public string Email { get; set; } [Required]
public string UserName { get; set; } [Required]//必须的
[DataType(DataType.Password)]//内容检查是否为密码
public string Password { get; set; }
}
}
修改AccountController,原来的_userManager和_signInManager不再使用
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Authentication.Cookies;
using System.Security.Claims;
using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
using Microsoft.AspNetCore.Identity;
using MvcCookieAuthSample.Models;
using System.Threading.Tasks;
using MvcCookieAuthSample.ViewModels;
using IdentityServer4.Test;
using System; namespace MvcCookieAuthSample.Controllers
{
public class AccountController : Controller
{
// private UserManager<ApplicationUser> _userManager;//创建用户的
// private SignInManager<ApplicationUser> _signInManager;//用来登录的 private readonly TestUserStore _users;
public AccountController(TestUserStore users)
{
_users=users;
} // //依赖注入
// public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager)
// {
// _userManager = userManager;
// _signInManager = signInManager;
// } //内部跳转
private IActionResult RedirectToLocal(string returnUrl)
{
if (Url.IsLocalUrl(returnUrl))
{//如果是本地
return Redirect(returnUrl);
} return RedirectToAction(nameof(HomeController.Index), "Home");
} //添加验证错误
private void AddError(IdentityResult result)
{
//遍历所有的验证错误
foreach (var error in result.Errors)
{
//返回error到model
ModelState.AddModelError(string.Empty, error.Description);
}
} public IActionResult Register(string returnUrl = null)
{
ViewData["returnUrl"] = returnUrl;
return View();
} [HttpPost]
public async Task<IActionResult> Register(RegisterViewModel registerViewModel, string returnUrl = null)
{
// if (ModelState.IsValid)
// {
// ViewData["returnUrl"] = returnUrl; // var identityUser = new ApplicationUser
// {
// Email = registerViewModel.Email,
// UserName = registerViewModel.Email,
// NormalizedUserName = registerViewModel.Email
// };
// var identityResult = await _userManager.CreateAsync(identityUser, registerViewModel.Password);
// if (identityResult.Succeeded)
// {
// //注册完成登录生成cookies信息
// await _signInManager.SignInAsync(identityUser, new AuthenticationProperties { IsPersistent = true }); // return RedirectToLocal(returnUrl);
// }
// else//注册失败
// {
// //添加验证错误
// AddError(identityResult);
// }
// } return View();
} public IActionResult Login(string returnUrl = null)
{
ViewData["returnUrl"] = returnUrl;
return View();
} [HttpPost]
public async Task<IActionResult> Login(LoginViewModel loginViewModel, string returnUrl = null)
{
if (ModelState.IsValid)
{
ViewData["returnUrl"] = returnUrl; //var user = await _userManager.FindByEmailAsync(loginViewModel.Email);
var user = _users.FindByUsername(loginViewModel.UserName); if (user == null)
{
ModelState.AddModelError(nameof(loginViewModel.UserName), "UserName not exists");
}
else
{
if (_users.ValidateCredentials(loginViewModel.UserName,loginViewModel.Password))
{
//是否记住
var prop = new AuthenticationProperties()
{
IsPersistent = true,
ExpiresUtc = DateTimeOffset.UtcNow.Add(TimeSpan.FromMinutes(30))
}; //HttpContext.SignInAsync(user.SubjectId, user.Username, prop);
await Microsoft.AspNetCore.Http.AuthenticationManagerExtensions.SignInAsync(HttpContext, user.SubjectId, user.Username, prop);
}
}
//账号密码先不做验证,需要可以自己写
//await _signInManager.SignInAsync(user, new AuthenticationProperties { IsPersistent = true }); return RedirectToLocal(returnUrl);
} return View(); } //登出
public async Task<IActionResult> Logout()
{ await HttpContext.SignOutAsync();
return RedirectToAction("Index", "Home");
} }
}
接下来我们需要将原来的Program.cs中的数据库初始化的内容注释掉
然后我们就可以运行网站,输入用户名和密码进行登录了
新建客户端
新建一个MVC网站MvcClient
dotnet new mvc --name MvcClient
给网站设置默认地址 http://localhost:5001
MVC的网站已经内置帮我们实现了Identity,所以我们不需要再额外添加Identity引用
添加认证
services.AddAuthentication(options =>
{
options.DefaultScheme = "Cookies";//使用Cookies认证
options.DefaultChallengeScheme = "oidc";//使用oidc
})
.AddCookie("Cookies")//配置Cookies认证
.AddOpenIdConnect("oidc",options=> {//配置oidc
options.SignInScheme = "Cookies";
options.Authority = "http://localhost:5000";
options.RequireHttpsMetadata = false; options.ClientId = "mvc";
options.ClientSecret = "secret";
options.SaveTokens = true;
});
在管道中使用Authentication
app.UseAuthentication();
Login.cshtml 页面接收returnUrl进行跳转
<form method="post" asp-controller="Account" asp-action="Login">
<h4>Use a local account to log in.</h4>
<hr />
@*用于登录后进行跳转*@
<input type="hidden" name="returnUrl" value="@ViewData["returnUrl"]" /> <div class="form-group">
<label asp-for="UserName"></label>
<input asp-for="UserName" class="form-control" />
<span asp-validation-for="UserName" class="text-danger"></span>
</div> <div class="form-group">
<label asp-for="Password"></label>
<input asp-for="Password" type="password" class="form-control" />
<span asp-validation-for="Password" class="text-danger"></span>
</div>
<div class="form-group">
<button type="submit" class="btn btn-block btn-danger">Log in</button>
</div> </form>
接下来我们在HomeController上打上 [Authorize] 标签,然后启动运行
我们这个时候访问首页http://localhost:5001会自动跳转到ocalhost:5000/account/login登录
登录之后会自动跳转回来
我们可以在Home/About页面将claim的信息显示出来
@{
ViewData["Title"] = "About";
}
<h2>@ViewData["Title"]</h2>
<h3>@ViewData["Message"]</h3> <dl>
@foreach (var claim in User.Claims)
{
<dt>@claim.Type</dt>
<dt>@claim.Value</dt>
}
</dl>
这边的内容是根据我们在IdentityServer服务中定义的返回资源决定的
