c# - Asp.net Core Identity - 操作步骤

1. Define a new class, derived from IdentityUser

public class AppUser : IdentityUser
    {
        public string DisplayName { get; set; }
    }

2. In your DataContext, change 
'public class DataContext : DbContext' 
to 
'public class DataContext : IdentityDbContext<AppUser>'

3. In your DataContext, method: 'protected override void OnModelCreating(ModelBuilder builder)' add code: 

base.OnModelCreating(builder);

4. Execute cmd:

dotnet ef migrations add "AddIdentity" -p Persistence -s API

5. In start project: "API" directory, execute cmd:

dotnet ef database update

7. In start project: "API" directory, add nuget package: 'Microsoft.AspNetCore.Identity.UI'

8. In start project: "API", method: 'public void ConfigureServices(IServiceCollection services)' add code below

// Add Identity Support
            var builder = services.AddIdentityCore<AppUser>();
            var identityBuilder = new IdentityBuilder(builder.UserType, builder.Services);
            identityBuilder.AddEntityFrameworkStores<DataContext>();
            identityBuilder.AddSignInManager<SignInManager<AppUser>>();

9. Add some seed data, using 'UserManager<AppUser> userManager':

 if (!userManager.Users.Any())
            {
                var users = new List<AppUser>
                {
                    new AppUser { DisplayName = "Bob", UserName = "bob", Email = "[email protected]" },
                    new AppUser { DisplayName = "Tom", UserName = "tom", Email = "[email protected]" },
                    new AppUser { DisplayName = "Jane", UserName = "jane", Email = "[email protected]" }
                };

                foreach(var user in users)
                {
                    await userManager.CreateAsync(user, "Pa$$w0rd");
                }
            }
