我需要知道问题的原因、解决方法,以及是否有Asp.Net Core 2.1依赖项注入激活器签名的文档。在回顾了开源实现之后,我找到了问题的线索,我猜对了。
UserStore
需要通过该行在Startup.ConfigureServices
中注册:
...
services.AddIdentityCore<Employee>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddUserStore<ApplicationUserStore>()
.AddUserManager<ApplicationUserManager>()
.AddSignInManager<ApplicationSignInManager>()
.AddDefaultTokenProviders();
services.AddTransient<IUserStore<Employee>, ApplicationUserStore>();
...
services.AddScoped<ApplicationUserStore>();
services.addScope();
因此,我的最终方法是:
...
services.AddIdentityCore<Employee>()
.AddUserManager<ApplicationUserManager>()
.AddSignInManager<ApplicationSignInManager>()
.AddDefaultTokenProviders();
services.AddScoped<IUserStore<Employee>, ApplicationUserStore>();
services.AddScoped<ApplicationUserStore>();
...
。。。
services.AddIdentityCore()
.AddUserManager()
.AddSignInManager()的名称
.AddDefaultTokenProviders();
services.addScope();
services.addScope();
...
尽管如此,它在没有:
services.AddScoped<IUserStore<Employee>, ApplicationUserStore>();
services.addScope();
如果声明services.AddTransient(),则不能在构造函数中使用ApplicationUserStore。你需要使用IUserStore@hugo. 不幸的是,在没有AddUserStore
的情况下使用AddTransient
对我不起作用,在没有AddTransient
的情况下使用AddUserStore
也不起作用;我一直收到相同的消息。您注册了ApplicationDbContext
?没有。该行只是告诉Identity要使用的IdentityDbContext的类型。它希望对其进行预配置和注册,例如services.AddDbContext()有限公司
