如何添加ApplicationUser作爲測試數據在dotnet核心

Question

我試圖初始化我的數據庫中的一些測試數據，並且在Identity Framework中向ApplicationUser添加密碼時遇到一些問題。

當我已經這樣做了前面，我已經使用這樣的種子方法：

protected override void Seed(ApplicationDbContext db) 
{ 
    var userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(db)); 

    var adminuser = new ApplicationUser { Email = "admin@test.no", UserName = "admin@test.no", FirstName = "admin", LastName = "test" }; 
    userManager.Create(adminuser, "Password1."); 
    userManager.AddToRole(adminuser.Id, role:"admin"); 
} 

但作爲種子法不DOTNET核心支持我試圖通過以下方式添加虛擬數據：

using (var serviceScope = 
app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope()) 
    db.Database.EnsureCreated(); 

    db.AddRange(
     new ApplicationUser { UserName = "ola@nordmann.no", Email = "ola@nordmann.no" }, 
     new ApplicationUser { UserName = "test@test.no", Email = "test@test.no" } 
    ); 
    db.SaveChanges(); 

我還試圖用我的種子方法用同樣的方法，但是，這並不工作，要麼我得到就行了以下錯誤消息是我RESULT1添加到數據庫：

無法從 'System.Threading.Tasks.Task' 轉換爲「Server.Models.ApplicationUser

using (var serviceScope = 
app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope()) 
{ 
    var db = serviceScope.ServiceProvider.GetService<ApplicationDbContext>(); 
    var userManager = app.ApplicationServices.GetService<UserManager<ApplicationUser>>(); 

    var au1 = new ApplicationUser { UserName = "test@test.no", Email = "test@test.no" }; 
    var result1 = userManager.CreateAsync(au1, "Test123"); 
    db.Users.Add(result1); 

Answer 1

如果任何人應該是有興趣的，我結束了以下解決方案：

public async Task CreateUsersAndRoles(IServiceScope serviceScope) 
{ 
    var userManager = serviceScope.ServiceProvider.GetService<UserManager<ApplicationUser>>(); 

    await userManager.CreateAsync(new ApplicationUser { UserName = "ola@nordmann.no", Email = "ola@nordmann.no"}, "Password1."); 
} 

，並在這樣的啓動文件的配置方法中調用此方法：

await CreateUsersAndRoles(app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope());

您可以結合使用PasswordHasher與用戶。

即

var user = new User(); 
var hasher = new PasswordHasher<User>(); 

db.AddRange(
     new ApplicationUser { UserName = "ola@nordmann.no", Email = "ola@nordmann.no", PasswordHash = hasher.HashPassword(user, "Password1") }, 

    ); 
    db.SaveChanges();
