ASP.NET Identity 3.0實體框架數據庫種子

Question

我正在使用ASP.NET 5 RC1，正在使用Identity 3.0通過內置的ASPNET架構和EF7使用用戶名/密碼提供身份驗證。

為了進行測試，我嘗試使用從Startup.cs調用的靜態方法為數據庫分配角色和用戶。 以下代碼可用於添加角色，但不適用於用戶。 （我找不到在Identity 3中使用新的RoleManager和UserManager類的任何示例代碼）。 我在這里使用對UserManager的正確方法調用嗎？

        if (!context.Roles.Any(r => r.Name == "Admin"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store, null, null, null, null, null);
            var role = new IdentityRole { Name = "Admin" };
            manager.CreateAsync(role);
        }

        if (!context.Roles.Any(r => r.Name == "User"))
        {
            var store = new RoleStore<IdentityRole>(context);
            var manager = new RoleManager<IdentityRole>(store, null, null, null, null, null);
            var role = new IdentityRole { Name = "User" };
            manager.CreateAsync(role);
        }

        if (!context.Users.Any(u => u.UserName == "darin"))
        {
            var store = new UserStore<ApplicationUser>(context);
            var manager = new UserManager<ApplicationUser>(store, null, null, null, null, null, null, null, null, null);
            var user = new ApplicationUser { UserName = "darin", Email = "dherle@gmail.com" };
            manager.CreateAsync(user, "admin");
            manager.AddToRoleAsync(user, "Admin");
        }

        if (!context.Users.Any(u => u.UserName == "chris"))
        {
            var store = new UserStore<ApplicationUser>(context);
            var manager = new UserManager<ApplicationUser>(store, null, null, null, null, null, null, null, null, null);
            var user = new ApplicationUser { UserName = "chris", Email = "dan@gmail.com" };
            manager.CreateAsync(user, "chris");
            manager.AddToRoleAsync(user, "User");
        }

Answer 1

我不確定為什么它對您不起作用。 可能是從哪里調用種子方法的？ 例如，當我從控制器中的某個動作調用用戶帳戶時，它就是在復制用戶帳戶。

當我按照此鏈接上的說明進行操作時，數據庫種子對RC1很有幫助。

問題是用戶創建塊中的CreateAsync調用。 當您調用manager.CreateAsync（user，“ chris”）時，您正在嘗試使用用戶名“ chris”和密碼“ chris”創建用戶。 這樣的密碼可能不符合Identity Framework的安全性限制。

無論如何，解決方案都很簡單：

 var user = new ApplicationUser { UserName = "chris", Email = "chris@chris.com" }; PasswordHasher<ApplicationUser> ph = new PasswordHasher<ApplicationUser>(); user.PasswordHash = ph.HashPassword(user, "admin3##"); //More complex password manager.CreateAsync(user); manager.AddToRoleAsync(user, "admin");

我檢查了ManageController中現有的樣板代碼。 似乎需要為Seeding方法設置修飾符異步，並在適當的地方使用await完成播種。

    public static async void SeedData(this IApplicationBuilder app)
    {
        var db = app.ApplicationServices.GetService<ApplicationDbContext>();

        db.Database.Migrate();
        //If no role found in the Roles table
        //RoleStore needs using Microsoft.AspNet.Identity.EntityFramework;
        var identityRoleStore = new RoleStore<IdentityRole>(db);
        var identityRoleManager = new RoleManager<IdentityRole>(identityRoleStore, null, null, null, null, null);

            var adminRole = new IdentityRole { Name = "ADMIN" };
        await identityRoleManager.CreateAsync(adminRole);



            var officerRole = new IdentityRole { Name = "OFFICER" };
        await identityRoleManager.CreateAsync(officerRole);




        var userStore = new UserStore<ApplicationUser>(db);
        var userManager = new UserManager<ApplicationUser>(userStore, null, null, null, null, null, null, null, null, null);


        var danielUser = new ApplicationUser { UserName = "DANIEL", Email = "DANIEL@EMU.COM" };
        PasswordHasher<ApplicationUser> ph = new PasswordHasher<ApplicationUser>();
         danielUser.PasswordHash = ph.HashPassword(danielUser, "P@ssw0rd!1"); //More complex password
        await userManager.CreateAsync(danielUser);

        await userManager.AddToRoleAsync(danielUser, "ADMIN");



           var susanUser = new ApplicationUser { UserName = "SUSAN", Email = "SUSAN@EMU.COM" };
           susanUser.PasswordHash = ph.HashPassword(susanUser, "P@ssw0rd!2"); //More complex password
        await userManager.CreateAsync(susanUser);

        await userManager.AddToRoleAsync(susanUser, "ADMIN");



            var randyUser = new ApplicationUser { UserName = "RANDY", Email = "RANDY@EMU.COM" };
        randyUser.PasswordHash = ph.HashPassword(randyUser, "P@ssw0rd!3"); //More complex password
        await userManager.CreateAsync(randyUser);

        await userManager.AddToRoleAsync(randyUser, "OFFICER");






        var thomasUser = new ApplicationUser { UserName = "THOMAS", Email = "THOMAS@EMU.COM" };
      thomasUser.PasswordHash = ph.HashPassword(thomasUser, "P@ssw0rd!4"); //More complex password

        await userManager.CreateAsync(thomasUser);
        await userManager.AddToRoleAsync(thomasUser, "OFFICER");

        var benUser = new ApplicationUser { UserName = "BEN", Email = "BEN@EMU.COM" };
        benUser.PasswordHash = ph.HashPassword(benUser, "P@ssw0rd!5"); //More complex password

        await userManager.CreateAsync(benUser);

        await userManager.AddToRoleAsync(benUser, "OFFICER");


          if (db.Courses.FirstOrDefault() == null)
          {
              Course ditCourse = new Course()
              {
                  CourseAbbreviation = "DIT",
                  CourseName = "DIPLOMA IN INFORMATION TECHNOLOGY",
                  CreatedById = randyUser.Id,
                  UpdatedById = thomasUser.Id
              };
              db.Courses.Add(ditCourse);
              Course dbitCourse = new Course()
              {
                  CourseAbbreviation = "DIPLOMA IN BUSINESS INFORMATION TECHNOLOGY",
                  CourseName = "DBIT",
                  CreatedById = thomasUser.Id,
                  UpdatedById = thomasUser.Id
              };
              db.Courses.Add(dbitCourse);
              Course dismCourse = new Course()
              {
                  CourseAbbreviation = "DISM",
                  CourseName = "DIPLOMA IN INFOCOMM SECURITY MANAGEMENT",
                  CreatedById = thomasUser.Id,
                  UpdatedById = benUser.Id
              };
              db.Courses.Add(dismCourse);

          }

        db.SaveChanges();
