在类库中访问User.Identity.GetUserId()的方法是通过使用ASP.NET Identity框架来实现用户身份验证和授权的功能。ASP.NET Identity是一个用于管理用户身份验证和授权的框架,它提供了一组API和类库,可以方便地在应用程序中进行用户身份验证和授权的操作。
要在类库中访问User.Identity.GetUserId()方法,需要进行以下步骤:
public class ApplicationUser : IdentityUser
{
// 可以在这里添加自定义的用户属性
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
: base(options)
{
}
}
public class ApplicationUserClaim : IdentityUserClaim<string>
{
}
public class ApplicationUserRole : IdentityUserRole<string>
{
}
public class ApplicationRole : IdentityRole<string>
{
}
public class ApplicationUserStore : UserStore<ApplicationUser>
{
public ApplicationUserStore(ApplicationDbContext context)
: base(context)
{
}
}
public class ApplicationRoleStore : RoleStore<ApplicationRole>
{
public ApplicationRoleStore(ApplicationDbContext context)
: base(context)
{
}
}
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
}
public class ApplicationRoleManager : RoleManager<ApplicationRole>
{
public ApplicationRoleManager(IRoleStore<ApplicationRole> store)
: base(store)
{
}
}
public class ApplicationSignInManager : SignInManager<ApplicationUser>
{
public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager)
: base(userManager, authenticationManager)
{
}
}
public class ApplicationUserManagerFactory : IdentityFactoryOptions<ApplicationUserManager>
{
public ApplicationUserManagerFactory()
{
Create = () => new ApplicationUserManager(new ApplicationUserStore(new ApplicationDbContext()));
}
}
public class ApplicationRoleManagerFactory : IdentityFactoryOptions<ApplicationRoleManager>
{
public ApplicationRoleManagerFactory()
{
Create = () => new ApplicationRoleManager(new ApplicationRoleStore(new ApplicationDbContext()));
}
}
public class ApplicationSignInManagerFactory : IdentityFactoryOptions<ApplicationSignInManager>
{
public ApplicationSignInManagerFactory()
{
Create = (context) => new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication);
}
}
public class ApplicationUserManagerFactory : IdentityFactory<ApplicationUserManager>
{
public override ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new ApplicationUserStore(context.Get<ApplicationDbContext>()));
// 在这里配置用户管理类的一些属性和行为
return manager;
}
}
public class ApplicationRoleManagerFactory : IdentityFactory<ApplicationRoleManager>
{
public override ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
{
var manager = new ApplicationRoleManager(new ApplicationRoleStore(context.Get<ApplicationDbContext>()));
// 在这里配置角色管理类的一些属性和行为
return manager;
}
}
public class ApplicationSignInManagerFactory : IdentityFactory<ApplicationSignInManager>
{
public override ApplicationSignInManager Create(IdentityFactoryOptions<ApplicationSignInManager> options, IOwinContext context)
{
var manager = new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication);
// 在这里配置登录管理类的一些属性和行为
return manager;
}
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
public class ApplicationUserClaim : IdentityUserClaim<string>
{
}
public class ApplicationUserRole : IdentityUserRole<string>
{
}
public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
public ApplicationRole()
{
}
public ApplicationRole(string roleName)
{
Name = roleName;
}
}
public class ApplicationUserStore : UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
public ApplicationUserStore(ApplicationDbContext context)
: base(context)
{
}
}
public class ApplicationRoleStore : RoleStore<ApplicationRole, string, ApplicationUserRole>
{
public ApplicationRoleStore(ApplicationDbContext context)
: base(context)
{
}
}
public class ApplicationUserManager : UserManager<ApplicationUser, string>
{
public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
: base(store)
{
}
}
public class ApplicationRoleManager : RoleManager<ApplicationRole, string>
{
public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
: base(store)
{
}
}
public class ApplicationSignInManager : SignInManager<ApplicationUser, string>
{
public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager)
: base(userManager, authenticationManager)
{
}
}
public class ApplicationUserManagerFactory : IdentityFactory<ApplicationUserManager>
{
public override ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new ApplicationUserStore(context.Get<ApplicationDbContext>()));
// 在这里配置用户管理类的一些属性和行为
return manager;
}
}
public class ApplicationRoleManagerFactory : IdentityFactory<ApplicationRoleManager>
{
public override ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
{
var manager = new ApplicationRoleManager(new ApplicationRoleStore(context.Get<ApplicationDbContext>()));
// 在这里配置角色管理类的一些属性和行为
return manager;
}
}
public class ApplicationSignInManagerFactory : IdentityFactory<ApplicationSignInManager>
{
public override ApplicationSignInManager Create(IdentityFactoryOptions<ApplicationSignInManager> options, IOwinContext context)
{
var manager = new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication);
// 在这里配置登录管理类的一些属性和行为
return manager;
}
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
public ApplicationDbContext()
: base("DefaultConnection", throwIfV1Schema: false)
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
通过以上步骤,我们在类库中就可以访问User.Identity.GetUserId()方法了。这个方法用于获取当前用户的唯一标识符。在ASP.NET Identity框架中,每个用户都有一个唯一的标识符,可以用来标识和区分不同的用户。
注意:以上步骤是基于ASP.NET Identity框架的使用,如果你使用的是其他身份验证和授权框架,可能需要进行相应的调整和修改。
