正在使用自定义角色初始化ASP.NET标识中的RoleManager

本文关键字:标识 NET RoleManager ASP 初始化 自定义 角色 | 更新日期: 2023-09-27 18:25:28

我使用这里的教程将用户数据库的主键从string更改为int,但在初始化角色管理器时遇到了困难。它曾经使用进行初始化

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:我使用的是MVC 5和EF 6。

正在使用自定义角色初始化ASP.NET标识中的RoleManager

您的ApplicationRoleManager可能是这样的。因为您必须从customRole类而不是IdentityRole继承。

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>()));
    }
}

如果Startup.Auth.cs类当前不存在,请将以下代码添加到该类中。

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

然后创建和管理角色。

    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);
    }

希望这能有所帮助。

根据您的问题,我无法确定您是否使用相同的框架(MVC和EF)。

最近,我使用自定义ApplicationUsers&身份角色。ApplicationUser派生自"Microsoft.AspNet.Identity.EntityFramework.IdentityUser"。ApplicationRoles是在没有更改的情况下实现的。

我有以下课程:

// 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>()));
        }
    }

在configuration.cs(迁移)中===>在"更新数据库"上将执行

    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);

在startup.auth.cs中,链接到RoleManager:

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

希望这能有所帮助。

    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")
            ;
        }
    }
