使用自定义角色初始化ASP.NET身份中的RoleManager

Question

使用教程here将用户数据库的主键从字符串更改为int，但我在初始化角色管理器时遇到困难。它曾经使用初始化

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context)); 

如何使用新数据创建角色管理器？

更新：我使用MVC 5和EF 6

您的ApplicationRoleManager可能看起来像这样。因为你必须继承你的customRole类而不是IdentityRole。

public class ApplicationRoleManager : RoleManager<CustomRole, int> 
{ 
    public ApplicationRoleManager(IRoleStore<CustomRole, int> roleStore) 
     : base(roleStore) 
    { 
    } 

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context) 
    { 
     return new ApplicationRoleManager(new RoleStore<CustomRole, int, CustomUserRole>(context.Get<ApplicationDbContext>())); 
    } 
} 

然后将以下代码添加到Startup.Auth.cs类（如果当前不存在）。

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create); 

然后您创建并管理角色。

var roleManager = HttpContext.GetOwinContext().Get<ApplicationRoleManager>(); 

    const string roleName = "Admin"; 

    //Create Role Admin if it does not exist 
    var role = roleManager.FindByName(roleName); 
    if (role == null) 
    { 
     role = new CustomRole(); 
     role.Id = 1; // this will be integer 
     role.Name = roleName; 

     var roleresult = roleManager.Create(role); 
    } 

希望这会有所帮助。

从你的问题，我不能确定是否使用相同的架构（MVC & EF）。

最近我创建了一个MVC + EF解决方案，使用自定义ApplicationUsers & IdentityRoles。 ApplicationUser来源于“Microsoft.AspNet.Identity.EntityFramework.IdentityUser”。 ApplicationRoles实现不变。

我有以下类：

// Configure the used in the application. RoleManager is defined in the ASP.NET Identity core assembly 
    public class ApplicationRoleManager : RoleManager<IdentityRole> 
    { 
     public ApplicationRoleManager(IRoleStore<IdentityRole, string> roleStore) 
      : base(roleStore) 
     { 
     } 

     public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context) 
     { 
      return new ApplicationRoleManager(new RoleStore<IdentityRole>(context.Get<ApplicationDbContext>())); 
     } 
    } 

内configuration.cs（迁移）==>在此将被执行

var roleStore = new RoleStore<IdentityRole>(context); 
    var roleManager = new RoleManager<IdentityRole>(roleStore); 
    var applicationRoleAdministrator = new IdentityRole("Administrator"); 
    if (!roleManager.RoleExists(applicationRoleAdministrator.Name)) 
    { 
     roleManager.Create(applicationRoleAdministrator); 
    } 
// do some logic to find your applicationUserAdministrator 
var applicationUserAdministrator = userManager.FindByName("Administrator"); 
userManager.AddToRole(applicationUserAdministrator.Id, applicationRoleAdministrator.Name); 

withing startup.auth.cs '更新数据库'朝向角色管理器的链接：

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

希望这会有所帮助。其中我有，如果我使用'

var roleManager = new RoleManager<CustomRole,int>(new RoleStore<CustomRole,int,CustomUserRole>(context)); 
    var UserManager = new UserManager<ApplicationUser,int>(new UserStore<ApplicationUser,CustomRole,int,CustomUserLogin,CustomUserRole,CustomUserClaim>(context)); 

    // In Startup iam creating first Admin Role and creating a default Admin User  
    if (!roleManager.RoleExists("Admin")){ 
    //first we create Admin rool 
     var role = new CustomRole(); 
     role.Name = "Admin"; 
     roleManager.Create(role); 
    } 

    ////Here we create a Admin super user who will maintain the website  
    if (UserManager.FindByName("Admin") == null){ 
     var user = new ApplicationUser() { UserName = "Admin" }; 
     string userPWD = "adminadmin"; 
     var chkUser = UserManager.Create(user, userPWD); 
     if (chkUser.Succeeded){ 
      var result1 = UserManager.AddToRole(user.Id, "Admin") 
      ; 
     } 
    }
