NET使用ABP框架搭建博客项目（二） 认证模块

既然是个小平台，那么肯定有用户认证模块，微软提供了一个认证框架供我们使用Microsoft.Owin，首先我们通过Nuget安装相关的资源包！

web需要安装如下：

  <package id="Microsoft.AspNet.Identity.Core" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Core.zh-Hans" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Owin" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Owin.zh-Hans" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Web.Optimization" version="1.1.3" targetFramework="net452" />
  <package id="Microsoft.Owin" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Host.SystemWeb" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security.Cookies" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security.OAuth" version="2.1.0" targetFramework="net452" />
  <package id="Owin" version="1.0" targetFramework="net452" />

Application项目安装如下：

  <package id="Microsoft.AspNet.Identity.Core" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Core.zh-Hans" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Owin" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.AspNet.Identity.Owin.zh-Hans" version="2.2.1" targetFramework="net452" />
  <package id="Microsoft.Owin" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security.Cookies" version="3.0.1" targetFramework="net452" />
  <package id="Microsoft.Owin.Security.OAuth" version="2.1.0" targetFramework="net452" />
  <package id="Owin" version="1.0" targetFramework="net452" />

Nuget资源包安装完成后我们开始写代码了。
首先我们在Application项目的Customers文件中建立Dto，新增实体Customer并且继承Domain的Customer，以及实现IUser《int》（因为我的实体对象主键是int型）。

 [AutoMap(typeof(Blog_Solution.Domain.Customers.Customer))]
public class Customer : Blog_Solution.Domain.Customers.Customer, IUser<int>
    {

public Customer()
        {
this.PasswordSalt = CommonHelper.GenerateRandomDigitCode(6);
        }

public string UserName
        {
get
            {
return this.LoginName;
            }

set
            {
this.UserName = LoginName;
            }
        }
    }

Customers文件中增加CustomerStore 类并且实现接口IUserStore《Customer,int》（注：Customer为dto的实体）。我们只需要实现我们所用到的部分函数就可以了

    /// <summary>
/// 用户仓储
/// </summary>
public class CustomerStore : IUserStore<Customer,int>
    {
#region Fields && Ctor
private readonly ICustomerService _customerService;

public CustomerStore(ICustomerService customerService)
        {
this._customerService = customerService;
        }

#endregion

#region Method

public Task CreateAsync(Customer user)
        {
throw new NotImplementedException();
        }

public Task DeleteAsync(Customer user)
        {
throw new NotImplementedException();
        }

public void Dispose()
        {
throw new NotImplementedException();
        }

public async Task<Customer> FindByIdAsync(int userId)
        {
var customer = _customerService.GetCustomerById(userId);

return new Customer
            {
                Id = customer.Id,
                CreationTime = customer.CreationTime,
                CustomerRoleId = customer.CustomerRoleId,
                Deleted = customer.Deleted,
                Email = customer.Email,
                LastIpAddress = customer.LastIpAddress,
                LastModificationTime = customer.LastModificationTime,
                LoginName = customer.LoginName,
                Mobile = customer.Mobile,
                Password = customer.Password,
                PasswordSalt = customer.PasswordSalt,
                PasswordFormat = customer.PasswordFormat,
                PasswordFormatId = customer.PasswordFormatId,
            };
        }

public async Task<Customer> FindByNameAsync(string userName)
        {
var customer = _customerService.GetCustomerByLoginName(userName);
return new Customer
            {
                Id = customer.Id,
                CreationTime = customer.CreationTime,
                CustomerRoleId = customer.CustomerRoleId,
                Deleted = customer.Deleted,
                Email = customer.Email,
                LastIpAddress = customer.LastIpAddress,
                LastModificationTime = customer.LastModificationTime,
                LoginName = customer.LoginName,
                Mobile = customer.Mobile,
                Password = customer.Password,
                PasswordSalt = customer.PasswordSalt,
                PasswordFormat = customer.PasswordFormat,
                PasswordFormatId = customer.PasswordFormatId,
            };
        }

public Task UpdateAsync(Customer user)
        {
throw new NotImplementedException();
        }
#endregion
    }

声明用户管理器CustomerManager实现类UserManager《Customer, int》（customer为dto的实体）

 public class CustomerManager : UserManager<Customer, int>
    {
public CustomerManager(IUserStore<Customer, int> store) : base(store)
        {
        }
    }

声明用户登录管理器LoginManager

/// <summary>
/// 登录模块
/// </summary>
public class LoginManager : SignInManager<Customer, int>, IApplicationService
    {
private readonly UserManager<Customer, int> _userManager;
private readonly IAuthenticationManager _authenticationManager;
public LoginManager(UserManager<Customer, int> userManager, AuthenticationManager authenticationManager)
            : base(userManager, authenticationManager)
        {
this._userManager = userManager;
this._authenticationManager = authenticationManager;
        }

public override Task SignInAsync(Customer user, bool isPersistent, bool rememberBrowser)
        {
return base.SignInAsync(user, isPersistent, rememberBrowser);
        }

    }

我们最后在Application项目中找到Blog_SolutionApplicationModule类，重写函数如下：

 public override void PostInitialize()
        {
            IocManager.Register<IAuthenticationManager, AuthenticationManager>();
            IocManager.Register<IUserStore<Customer, int>, CustomerStore>();
            IocManager.Register<UserManager<Customer, int>, CustomerManager>();
//IocManager.Register<SignInManager<Customer, int>, LoginManager>();
//base.PostInitialize();
        }

上面这段代码是为了注入项目中。

好了，基础工作我们搞定了，现在只需要配置好控制就可以了

public class AccountController : Blog_SolutionControllerBase
    {
#region Fields && Ctor

private readonly LoginManager _loginManage;
private readonly CustomerManager _customerManager;
private readonly IAuthenticationService _authenticationService;

public AccountController(IAuthenticationService authenticationService,
                                LoginManager loginManager,
                                CustomerManager customerManager)
        {
this._authenticationService = authenticationService;
this._loginManage = loginManager;
this._customerManager = customerManager;
        }

#endregion

#region Utilities
private IAuthenticationManager AuthenticationManager
        {
get
            {
return HttpContext.GetOwinContext().Authentication;
            }
        }
#endregion

#region Login / Logout
public ActionResult Login(string returnUrl = "")
        {
if (string.IsNullOrWhiteSpace(returnUrl))
            {
                returnUrl = Request.ApplicationPath;
            }

            ViewBag.returnUrl = returnUrl;
var model = new LoginModel();
return View(model);
        }

        [HttpPost]
        [DisableAuditing]
public ActionResult Login(LoginModel model)
        {
var loginResult = _authenticationService.ValidateCustomer(model.LoginName, model.Password);
switch (loginResult.Result)
            {
case LoginResults.Successful:
                    {
//生成ClaimsIdentity
var identity = _loginManage.CreateUserIdentity(loginResult.Customer);

//用户登录
                        AuthenticationManager.SignIn(new AuthenticationProperties { IsPersistent = model.RememberMe }, identity);

if (String.IsNullOrEmpty(model.ReturnUrl) || !Url.IsLocalUrl(model.ReturnUrl))
return RedirectToAction("Index", "Home");

return Redirect(model.ReturnUrl);
                    }

case LoginResults.Deleted:
                    ModelState.AddModelError("", L("Account.Login.WrongCredentials.Deleted"));
break;
case LoginResults.NotActive:
                    ModelState.AddModelError("", L("Account.Login.WrongCredentials.NotActive"));
break;
case LoginResults.NotRegistered:
                    ModelState.AddModelError("", L("Account.Login.WrongCredentials.NotRegistered"));
break;
case LoginResults.WrongPassword:
default:
                    ModelState.AddModelError("", L("Account.Login.WrongCredentials"));
break;
            }

return View(model);
        }


public ActionResult Logout()
        {
            AuthenticationManager.SignOut();
return Redirect("/");
        }

#endregion

    }

所有步骤完成后，我们还有最后一步，就是在你的web项目中增加一个启动项（Owin Start类）

[assembly: OwinStartup(typeof(Blog_Solution.Web.App_Start.Startup))]

namespace Blog_Solution.Web.App_Start
{
public class Startup
    {
public void Configuration(IAppBuilder app)
        {
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login")
            });

            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                CookieHttpOnly = true,
                CookieName = "__BLOG_WEB"
            });

            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

        }

private static bool IsTrue(string appSettingName)
        {
return string.Equals(
                ConfigurationManager.AppSettings[appSettingName],
"true",
                StringComparison.InvariantCultureIgnoreCase);
        }
    }
}

搞定了！

这样，我们就完成用户的认证模块，在abp项目中，只要在生命周期内，可以使用AbpSession.UserId来获取用户的主键信息。
