c# - 使用 RoleManager 创建新角色

问题描述

我创建了一个上下文（带脚手架）和一个用户。我还设置播放数据库（并创建了迁移）。这完美！我现在只想创建一个角色，然后将其分配给用户。

为此，我修改了我的 startup.cs 文件以继续（我无法找到说明如何创建/分配具有与 ApplicationDbContext 不同上下文的角色的教程）。

我对代码中的错误感到满意（至少我认为），但我不知道如何处理它以及替换对象的内容。

因此，我创建了一个接收 serviceProvider（类型为 IServiceProvider）的 CreateRoles 方法，并在此方法中尝试初始化 romes，然后将它们分配给我的数据库的不同用户。

我关心的是这里（我认为）：

var RoleManager = serviceProvider.GetRequiredService > ();

事实上，我认为除了我使用 jakformulaireContext 之外，它是否用于 ApplicationDbContext。

我的问题是：我应该更换什么（如果那是我需要更换的）？

如果您需要模式信息或模式代码，请告诉我！

此错误通常发生在您创建自己的IdentityRole或忘记注册RoleManager.

如果您已通过自定义上下文class jakformulaireContext : IdentityDbContext<YourAppUser, YourIdentityRole>，请确保您使用该RoleManager<IdentityRole>服务的任何地方都已替换为RoleManager< YourIdentityRole>

另外，请确保RoleManager<YourIdentityRole>已注册. 如果您不创建自己的版本IdentityRole，只需调用.AddRoleManager<RoleManager<IdentityRole>>()

 services.AddIdentity<jakformulaireUser, IdentityRole>() 
    .AddRoleManager<RoleManager<IdentityRole>>()  // make sure the roleManager has been registered .
    .AddDefaultUI() 
    // other features ....
    .AddEntityFrameworkStores<jakformulaireContext>()
