前言
之前我们进行了MVC的web页面的Cookie-based认证实现，接下来的开发我们要基于之前的MvcCookieAuthSample项目做修改。
MvcCookieAuthSample项目地址：http://www.cnblogs.com/wyt007/p/8128186.html
UI
我们首先在AccountController中添加两个Action
public IActionResult SignIn()
{
return View();
}
public IActionResult Login()
{
return View();
}
然后在Views文件夹下新增Account文件夹并新增Register.cshtml与Login.cshtml视图，样式我们尽量从上一节的Identity视图中拷贝过来。
我们还需要新建一个ViewModels，在ViewModels中新建RegisterViewModel.cs来接收表单提交的值以及来进行强类型视图
namespace MvcCookieAuthSample.ViewModels
{
public class RegisterViewModel
{
//邮箱
public string Email { get; set; }
//密码
public string Password { get; set; }
//确认密码
public string ConfirmedPassword { get; set; }
}
}
Register.cshtml代码（只保留部分拷贝过来的内容，并加入强类型视图引用）：
@{
ViewData["Title"] = "Register";
}
@using MvcCookieAuthSample.ViewModels;
@model RegisterViewModel;
<h2>@ViewData["Title"]</h2>
<h3>@ViewData["Message"]</h3>
<div class="row">
<div class="col-md-4">
<form method="post">
<h4>Create a new account.</h4>
<hr />
<div class="form-group">
<label asp-for="Email"></label>
<input asp-for="Email" class="form-control" />
</div>
<div class="form-group">
<label asp-for="Password"></label>
<input asp-for="Password" class="form-control" />
</div>
<div class="form-group">
<label asp-for="ConfirmedPassword"></label>
<input asp-for="ConfirmedPassword" class="form-control" />
</div>
<button type="submit" class="btn btn-default">Register</button>
</form>
</div>
</div>
Login.cshtml代码（只保留部分拷贝过来的内容，并加入强类型视图引用）：
@{
ViewData["Title"] = "Login";
}
@using MvcCookieAuthSample.ViewModels;
@model RegisterViewModel;
<div class="row">
<div class="col-md-4">
<section>
<form method="post">
<h4>Use a local account to log in.</h4>
<hr />
<div class="form-group">
<label asp-for="Email"></label>
<input asp-for="Email" class="form-control" />
</div>
<div class="form-group">
<label asp-for="Password"></label>
<input asp-for="Password" type="password" class="form-control" />
</div>
<div class="form-group">
<button type="submit" class="btn btn-default">Log in</button>
</div>
</form>
</section>
</div>
</div>
然后在_Layout.cshtml中添加导航代码：
<ul class="nav navbar-nav navbar-right">
<li><a asp-area="" asp-controller="Account" asp-action="Register">Register</a></li>
<li><a asp-area="" asp-controller="Account" asp-action="Login">Log in</a></li>
</ul>
然后运行网站，UI已经实现
EF + Identity实现
EF实现
首先我们添加一个Data文件夹，由于VSCode的代码提示不是很好，接下来我们用VS2017开发。
我们首先在Models文件夹下面新建ApplicationUser.cs与ApplicationUserRole.cs
ApplicationUser.cs代码：
using Microsoft.AspNetCore.Identity;
namespace MvcCookieAuthSample.Models
{
public class ApplicationUser:IdentityUser<int>//不加int的话是默认主键为guid
{
}
}
ApplicationUserRole.cs代码：
using Microsoft.AspNetCore.Identity;
namespace MvcCookieAuthSample.Models
{
public class ApplicationUserRole: IdentityRole<int>//不加int的话是默认主键为guid
{
}
}
然后在Data文件夹下新建一个ApplicationDbContext.cs类，使它继承IdentityDbContext
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using MvcCookieAuthSample.Models;
namespace MvcCookieAuthSample.Data
{
public class ApplicationDbContext:IdentityDbContext<ApplicationUser, ApplicationUserRole,int>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options):base(options)
{
}
}
}
然后我们需要在Startup.cs添加EF的注册进来
//使用配置ApplicationDbContext使用sqlserver数据库，并配置数据库连接字符串
services.AddDbContext<ApplicationDbContext>(options=> {
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
});
然后我们需要在appsettings.json中配置数据库连接字符串
"ConnectionStrings": {
"DefaultConnection": "Server=192.168.1.184;Database=aspnet-IdentitySample-9A22BB3E-8D53-4F44-B533-2EF927C959DE;Trusted_Connection=True;MultipleActiveResultSets=true;uid=sa;pwd=123456"
}
EF实现结束
Identity实现
我们需要在Startup.cs添加Identity的注册进来
//配置Identity
services.AddIdentity<ApplicationUser, ApplicationUserRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
由于默认的Identity在密码上限制比较严格，我们把它改的宽松简单一点（不设置也行）
//修改Identity配置
services.Configure<IdentityOptions>(options =>
{
options.Password.RequireLowercase = false;//需要小写
options.Password.RequireNonAlphanumeric = false;//需要字母
options.Password.RequireUppercase = false;//需要大写
});
然后我们把认证的地址改成/Account/Login
然后我们修改AccountController，加入以下代码
private UserManager<ApplicationUser> _userManager;//创建用户的
private SignInManager<ApplicationUser> _signInManager;//用来登录的
//依赖注入
public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager)
{
_userManager = userManager;
_signInManager = signInManager;
}
[HttpPost]
public async Task<IActionResult> Register(RegisterViewModel registerViewModel)
{
var identityUser = new ApplicationUser
{
Email = registerViewModel.Email,
UserName = registerViewModel.Email,
NormalizedUserName = registerViewModel.Email
};
var identityResult=await _userManager.CreateAsync(identityUser, registerViewModel.Password);
if (identityResult.Succeeded)
{
return RedirectToAction("Index", "Home");
}
return View();
}
完整的AccountController
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using MvcCookieAuthSample.Models;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authentication.Cookies;
using System.Security.Claims;
using MvcCookieAuthSample.ViewModels;
using Microsoft.AspNetCore.Identity;
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
//依赖注入
public AccountController(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signInManager)
{
_userManager = userManager;
_signInManager = signInManager;
}
public IActionResult Register()
{
return View();
}
[HttpPost]
public async Task<IActionResult> Register(RegisterViewModel registerViewModel)
{
var identityUser = new ApplicationUser
{
Email = registerViewModel.Email,
UserName = registerViewModel.Email,
NormalizedUserName = registerViewModel.Email
};
var identityResult=await _userManager.CreateAsync(identityUser, registerViewModel.Password);
if (identityResult.Succeeded)
{
return RedirectToAction("Index", "Home");
}
return View();
}
public IActionResult Login()
{
return View();
}
//登陆
public IActionResult MakeLogin()
{
var claims=new List<Claim>(){
new Claim(ClaimTypes.Name,"wyt"),
new Claim(ClaimTypes.Role,"admin")
};
var claimIdentity= new ClaimsIdentity(claims,CookieAuthenticationDefaults.AuthenticationScheme);
HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme,new ClaimsPrincipal(claimIdentity));
return Ok();
}
//登出
public IActionResult Logout()
{
HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
return Ok();
}
}
}
接下来我们重新生成一下，我们需要执行shell命令生成一下数据库，只有添加 Microsoft.EntityFrameworkCore.Tools 才会生成成功，否则会报以下错误
执行命令总是提示 未找到与命令“dotnet-ef”匹配的可执行文件，根据网上的解决办法引用 Microsoft.EntityFrameworkCore.Tools 问题依旧不能得到解决。
解决办法：
右击项目弹出菜单点击编辑***.csprog,增加如下配置。
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
</ItemGroup>
执行增加配置命令后
这时候Data文件夹下已经有新增的数据库更新配置文件了
然后我们执行更新命令，执行成功后我们就可以看到数据库表已经生成了
接下来我们运行一下网站进行注册，注册成功，已经存储进数据库
