【问题描述】：

我正在尝试编写从 Asp.Net Mvc 6 中的 Startup.cs 创建默认管理员超级用户的代码，我可以只添加所有用户角色，但我无法自动将管理员用户分配到 AspNetUsers 表中.一些专家可以帮助我纠正这个问题，因为我的嵌入代码如下：

private async Task CreateRoles(ApplicationDbContext context, IServiceProvider serviceProvider)
{
    var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
    var roleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    // First, Creating User role as each role in User Manager  
    List<IdentityRole> roles = new List<IdentityRole>();
    roles.Add(new IdentityRole {Name = "Admin", NormalizedName = "ADMINISTRATOR"});
    roles.Add(new IdentityRole { Name = "Member", NormalizedName = "MEMBER" });
    roles.Add(new IdentityRole { Name = "Librarian", NormalizedName = "LIBRARIAN" });
    roles.Add(new IdentityRole { Name = "Borrower", NormalizedName = "BORROWER" });
    roles.Add(new IdentityRole { Name = "Reader", NormalizedName = "READER" });

   //Then, the machine added Default User as the Admin user role
    foreach (var role in roles)
    {
        var roleExit = await roleManager.RoleExistsAsync(role.Name);
        if (!roleExit)
        {
            context.Roles.Add(role);
            context.SaveChanges();
        }
    }
    //Next, I create an Admin Super User who will maintain the LMS website panel
    var userAdmin = new ApplicationUser()
    {
        UserName = "TrueMan",
        Email = "alpha@lms.com",
    };
    string userPWD = "Alpha@Mega";
    var chkUser = userManager.AddPasswordAsync(userAdmin, userPWD);
    if (chkUser.IsFaulted)
    {
        await roleManager.CreateAsync(new IdentityRole { Name = "Admin", NormalizedName = "ADMINISTRATOR" });
    }
    userAdmin = await userManager.FindByNameAsync("TrueMan");
    await userManager.AddToRoleAsync(userAdmin, "Admin");
    //await userManager.AddToRoleAsync(user, "Admin");
}

此代码在我创建新项目时有效，但我不想让 userId 具有长 id var user = await UserManager.FindByIdAsync("7bd66984-a290-4442-a9f8-5659e01b0c06");因此，我希望我的第一个管理员分配给管理员超级用户，以便更改为分配另一个用户角色。

private async Task CreateRoles(ApplicationDbContext context, IServiceProvider serviceProvider)
{
    var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
    var roleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    // First, Creating User role as each role in User Manager  
    List<IdentityRole> roles = new List<IdentityRole>();
    roles.Add(new IdentityRole {Name = "Admin", NormalizedName = "ADMINISTRATOR"});
    roles.Add(new IdentityRole { Name = "Member", NormalizedName = "MEMBER" });
    roles.Add(new IdentityRole { Name = "Librarian", NormalizedName = "LIBRARIAN" });
    roles.Add(new IdentityRole { Name = "Borrower", NormalizedName = "BORROWER" });
    roles.Add(new IdentityRole { Name = "Reader", NormalizedName = "READER" });

   //Then, the machine added Default User as the Admin user role
    foreach (var role in roles)
    {
        var roleExit = await roleManager.RoleExistsAsync(role.Name);
        if (!roleExit)
        {
            context.Roles.Add(role);
            context.SaveChanges();
        }
    }
//    var user = await UserManager.FindByIdAsync("7bd66984-a290-4442-a9f8-5659e01b0c06");
        //    await UserManager.AddToRoleAsync(user, "Admin");
}

从 //Next，我创建一个管理员超级用户，当我使用命令行执行时，他将维护 LMS 网站面板：dnx web;我的回应是“访问被拒绝”。看来我不能错过一些密码验证。

【解决方案3】：

首先请检查 [AspNetRoles] 表是否包含重复的 admin 并删除它们。我认为这行应该是：

var roleExit = await roleManager.RoleExistsAsync(role.NormalizedName);

然后：

string userPWD = "Alpha@1Mega";    
await userManager.CreateAsync(userAdmin, userPWD);
var user =  await userManager.FindByNameAsync("TrueMan");
if(!(await userManager.IsInRoleAsync(user, "Admin")))
    await userManager.AddToRoleAsync(user, "Admin");

不确定我是否正确，但如果您想以管理员角色创建用户，我会执行以下操作。

private async Task CreateRoles(ApplicationDbContext context, IServiceProvider serviceProvider)
{
    var userManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();
    var roleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    // First, Creating User role as each role in User Manager  
    List<IdentityRole> roles = new List<IdentityRole>();
    roles.Add(new IdentityRole {Name = "Admin", NormalizedName = "ADMINISTRATOR"});
    roles.Add(new IdentityRole { Name = "Member", NormalizedName = "MEMBER" });
    roles.Add(new IdentityRole { Name = "Librarian", NormalizedName = "LIBRARIAN" });
    roles.Add(new IdentityRole { Name = "Borrower", NormalizedName = "BORROWER" });
    roles.Add(new IdentityRole { Name = "Reader", NormalizedName = "READER" });

   //Then, the machine added Default User as the Admin user role
    foreach (var role in roles)
    {
        var roleExit = await roleManager.RoleExistsAsync(role.Name);
        if (!roleExit)
        {
            context.Roles.Add(role);
            context.SaveChanges();
        }
    }

    await CreateUser(context, userManager)
    }
}

private async Task CreateUser(ApplicationDbContext context, UserManager<ApplicationUser> userManager)
{
    var adminUser = await userManager.FindByEmailAsync("alpha@lms.com");
    if (adminUser != null)
    {
        if (!(await userManager.IsInRoleAsync(adminUser.Id, "Admin")))
            userManager.AddToRoleAsync(adminUser.UserName, "Admin");
    }
    else
    {
        var newAdmin = new ApplicationUser()
        {
            UserName = "TrueMan",
            Email = "alpha@lms.com",
        };
        await userManager.CreateAsync(newAdmin, "Alpha@Mega");
        await userManager.AddToRoleAsync(newAdmin.userName, "Admin");
    }
}

您能否具体说明您的问题出在哪里？
