AspNet.Identity自定义用户和自定义角色应该很简单;我失踪了什么？

本文介绍了AspNet.Identity自定义用户和自定义角色应该很简单;我失踪了什么？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

使用的示例我已经得到了远。 RoleManager 完美无缺，我将 UserManager 相同。我认为一切都是正确的，但我似乎无法在控制器中正确添加一个 UserManager 。哪里不对？有一点，我成功地获得了 UserManager 的工作，但是获得了一个 EntityValidationError ，说需要ID，当使用 UserManager.Create（user，password）; 创建一个新用户，发布在此问题

所以经过一段时间的命中和错过，我已经创建了以下所有内容，但是在新的ApplicationUserManager（新的ApplicationUserStore（新的MyAppDb（）））上得到编译时错误。说：在我的控制器中尝试创建UserManager时，MyApp.Models.ApplicationUserManager.ApplicationUserManager（Microsoft.AspNet.Identity.IUserStore）中的最佳重载方法匹配有一些无效参数：

这是控制器：

 命名空间MyApp.Controllers 
 {
 [授权] 
 public class AccountController：BaseController 
 {
 public AccountController ）
：this（new ApplicationUserManager（new ApplicationUserStore（new MyAppDb（）））
 {
} 
 
 public AccountController（ApplicationUserManager userManager）
 { 
 UserManager = userManager; 
} 
 
 public ApplicationUserManager UserManager {get;私人集合} 
 ... 
}

这是模型：

 命名空间MyApp.Models 
 {
 public class ApplicationUser：IdentityUser< string，ApplicationUserLogin，ApplicationUserRole，ApplicationUserClaim> 
 {
 [必需] 
 [StringLength（50）] 
 public string FirstName {get;组; 
 
 [必需] 
 [StringLength（50）] 
 public string LastName {get;组; } 
 
 
 public async任务< ClaimsIdentity> GenerateUserIdentityAsync（UserManager< ApplicationUser> manager）
 {
 //请注意，authenticationType必须与CookieAuthenticationOptions.AuthenticationType 
中定义的那个匹配。var userIdentity = await manager.CreateIdentityAsync（this，DefaultAuthenticationTypes.ApplicationCookie）; 
 //在此添加自定义用户声明
 return userIdentity; 
} 
} 
 
 public class ApplicationUserLogin：IdentityUserLogin< string> 
 {
} 
 
 public class ApplicationUserClaim：IdentityUserClaim< string> 
 {
} 
 
 public class ApplicationUserRole：IdentityUserRole< string> 
 {
} 
 
 public class ApplicationRole：IdentityRole< string，ApplicationUserRole> 
 {
 [必需] 
 [StringLength（50）] 
 public string ProperName {get;组; 
 
 [必需] 
 public string说明{get;组; } 
} 
 
 
 public class MyAppDb：IdentityDbContext< ApplicationUser，ApplicationRole，string，ApplicationUserLogin，ApplicationUserRole，ApplicationUserClaim> 
 {
 public MyAppDb（）
：base（MyAppDb）
 {
} 
} 
 
 
 public class ApplicationUserManager：UserManager< ApplicationUser> 
 {
 public ApplicationUserManager（IUserStore< ApplicationUser> store）
：base（store）
 {
 this.PasswordValidator =（IIdentityValidator< string>）new MinimumLengthValidator ）; 
 this.UserValidator = new UserValidator< ApplicationUser>（this）{AllowOnlyAlphanumericUserNames = false，RequireUniqueEmail = true}; 
} 
 
} 
 
 public class ApplicationUserStore：UserStore< ApplicationUser，ApplicationRole，string，ApplicationUserLogin，ApplicationUserRole，ApplicationUserClaim> 
 {
 public ApplicationUserStore（MyAppDb context）
：base（context）
 {
} 
 
 public override Async任务CreateAsync（ApplicationUser用户）
 {
 await base.CreateAsync（user）; 
 
} 
} 
 
 
 public class ApplicationRoleStore：RoleStore< ApplicationRole，string，ApplicationUserRole> 
 {
 public ApplicationRoleStore（MyAppDb context）
：base（context）
 {
} 
} 
 
 public class ApplicationRoleManager ：RoleManager< ApplicationRole> 
 {
 public ApplicationRoleManager（IRoleStore< ApplicationRole，string> store）
：base（store）
 {
} 
 
} 
}

更新：我可以得到错误消失通过更改这个来创建 UserManager ：

  public class ApplicationUserManager：的UserManager< ApplicationUser> 
 {
 public ApplicationUserManager（IUserStore< ApplicationUser> store）
：base（store）
 {
 this.PasswordValidator =（IIdentityValidator< string>）new MinimumLengthValidator ）; 
 this.UserValidator = new UserValidator< ApplicationUser>（this）{AllowOnlyAlphanumericUserNames = false，RequireUniqueEmail = true}; 
} 
}

到：

  public class ApplicationUserManager：UserManager< ApplicationUser> 
 {
 public ApplicationUserManager（IUserStore< ApplicationUser，string> store）
：base（store）
 {
 this.PasswordValidator =（IIdentityValidator< string>）new MinimumLengthValidator （8）; 
 this.UserValidator = new UserValidator< ApplicationUser>（this）{AllowOnlyAlphanumericUserNames = false，RequireUniqueEmail = true}; 
} 
}

注意我刚添加字符串，但是它会将错误最佳重载方法匹配Microsoft.AspNet.Identity.UserMaager.UserManager（Microsoft.AspNet.Identity.IUserStore）'在 base（store）。

更新2：我更改了：

  public class ApplicationUserManager：UserManager< ApplicationUser> 
 {
 public ApplicationUserManager（IUserStore< ApplicationUser，string> store）
 ... 
 $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ 
 
 
 
  p>  public class ApplicationUserManager：UserManager< ApplicationUser，string> 
 {
 public ApplicationUserManager（IUserStore< ApplicationUser，string> store）
 ... 
}

请注意<$ c中的'字符串 $ c> public class ApplicationUserManager：UserManager< Appl icationUser，string> 。但现在，猜猜是什么？你猜到了 - 回到这个问题：

我缺少什么？ / p>

解决方案

尝试这种方式。我有同样的问题，你需要提供id。

  // 
 // POST：/ Account / Register 
 [HttpPost] 
 [AllowAnonymous] 
 [ValidateAntiForgeryToken] 
 public async任务< ActionResult>注册（RegisterViewModel模型）
 {
 if（ModelState.IsValid）
 {
 var user = new ApplicationUser（）{
 UserName = model.UserName，
 Id = Guid.NewGuid（）。ToString（），
 Created = DateTime.Now，
 LastLogin = null 
}; 
 
 var result = await UserManager.CreateAsync（user，model.Password）; 
 if（result.Succeeded）
 {
 await SignInAsync（user，isPersistent：false）; 
 return RedirectToAction（Index，Home）; 
} 
 else 
 {
 AddErrors（result）; 
} 
 
 
 
} 
 
 //如果我们得到这么远的东西，失败了，重新显示窗体
 return View（模型）; 
}

Using examples from http://www.asp.net/identity I've gotten this far. The RoleManager works flawlessly and I treat the UserManager the same. I think everything is correct, but I can't seem to new up a UserManager correctly in a controller. What is wrong? At one point, I was successfully getting the UserManager to work but was getting an EntityValidationError saying "Id is required" when creating a new user with UserManager.Create(user, password); as posted in this question UserManager.Create(user, password) thowing EntityValidationError saying Id is required?

So after some time of hit and miss, I've created everything like the following but am getting a compile-time error on new ApplicationUserManager(new ApplicationUserStore(new MyAppDb())) saying, "The best overloaded method match for 'MyApp.Models.ApplicationUserManager.ApplicationUserManager(Microsoft.AspNet.Identity.IUserStore)' has some invalid arguments" when trying to create the 'UserManager' in my controller:

Here is the controller:

namespace MyApp.Controllers
{
    [Authorize]
    public class AccountController : BaseController
    {
        public AccountController()
            : this(new ApplicationUserManager(new ApplicationUserStore(new MyAppDb())))
        {
        }

        public AccountController(ApplicationUserManager userManager)
        {
            UserManager = userManager;
        }

        public ApplicationUserManager UserManager { get; private set; }
...
}

Here is the model:

namespace MyApp.Models
{
    public class ApplicationUser : IdentityUser<string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        [Required]
        [StringLength(50)]
        public string FirstName { get; set; }

        [Required]
        [StringLength(50)]
        public string LastName { get; set; }


        public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
        {
            // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
            var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
            // Add custom user claims here
            return userIdentity;
        }
    }

    public class ApplicationUserLogin : IdentityUserLogin<string>
    {
    }

    public class ApplicationUserClaim : IdentityUserClaim<string>
    {
    }

    public class ApplicationUserRole : IdentityUserRole<string>
    {
    }

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
    {
        [Required]
        [StringLength(50)]
        public string ProperName { get; set; }

        [Required]
        public string Description { get; set; }
    }


    public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        public MyAppDb()
            : base("MyAppDb")
        {
        }
    }


    public class ApplicationUserManager : UserManager<ApplicationUser>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser> store)
            : base(store)
        {
            this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
            this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
        }

    }

    public class ApplicationUserStore : UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    {
        public ApplicationUserStore(MyAppDb context)
            : base(context)
        {
        }

        public override async Task CreateAsync(ApplicationUser user)
        {
            await base.CreateAsync(user);

        }
    }


    public class ApplicationRoleStore : RoleStore<ApplicationRole, string, ApplicationUserRole>
    {
        public ApplicationRoleStore(MyAppDb context)
            : base(context)
        {
        }
    }

    public class ApplicationRoleManager : RoleManager<ApplicationRole>
    {
        public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
            : base(store)
        {
        }

    }
}

UPDATE: I can get the error to go away on the creation of the UserManager by changing this:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    {
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
    }
}

to this:

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        : base(store)
    {
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this) { AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true };
    }
}

notice I just added , string, but it then puts the error "The best overloaded method match for "Microsoft.AspNet.Identity.UserMaager.UserManager(Microsoft.AspNet.Identity.IUserStore)' has some invalid arguments" on base(store).

UPDATE 2: I changed this:

public class ApplicationUserManager : UserManager<ApplicationUser>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    }

to this:

public class ApplicationUserManager : UserManager<ApplicationUser, string>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    }

Notice the ' string in public class ApplicationUserManager : UserManager<ApplicationUser, string>. But now, guess what? You guessed it--back to this issue: UserManager.Create(user, password) thowing EntityValidationError saying Id is required?

What am I missing?

解决方案

Try this way. I had the same issue, you need to provide the id.

    //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = new ApplicationUser() {
                UserName = model.UserName,
                Id = Guid.NewGuid().ToString(),
                Created = DateTime.Now,
                LastLogin = null
            };

            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                await SignInAsync(user, isPersistent: false);
                return RedirectToAction("Index", "Home");
            }
            else
            {
                AddErrors(result);
            }



        }

        // If we got this far, something failed, redisplay form
        return View(model);
    }
