我在ASP.NET Web API Token Auth中遇到了一些问题。
基本上我创建了一个具有一些声明的用户(值存储在AspNetUserClaim表中)但是当创建用户身份时,这些声明不会从数据库中提取。
我的设置细分如下。
用户类:具有GenerateUserIdentityAsync方法(非常标准)和一些自定义属性:
public class LibraryUser : IdentityUser{
//Add Custom Properties Here
public string Company { get; set; }
public string DisplayName { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<LibraryUser> manager, string authenticationType)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, authenticationType);
// Add custom user claims here
return userIdentity;
}
}
我的DBContext声明了一些简单的名称更改,以使数据库看起来更好
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
// Modify the Model creation properties..
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
//Rename Identity 2.0 Tables to something nicer..
modelBuilder.Entity<LibraryUser>().ToTable("LibraryUser");
modelBuilder.Entity<IdentityUser>().ToTable("LibraryUser");
modelBuilder.Entity<IdentityRole>().ToTable("Role");
modelBuilder.Entity<IdentityUserRole>().ToTable("UserRole");
modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaim");
modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogin");
}
我有一个名为LibraryUserManager的简单UserManager类,它只为我的用户类型扩展UserManager。
public class LibraryUserManager : UserManager<LibraryUser>
当数据库被播种时(调用Update-Database时),将创建以下用户:
// -- Create Admin User, put in admin role..
LibraryUserManager userManager = new LibraryUserManager(new UserStore<LibraryUser>(context));
var user = new LibraryUser()
{
UserName = "admin@admin.com",
Email = "admin@admin.com",
DisplayName = "Administrator",
Company = "Test"
};
userManager.Create(user, "Password1.");
userManager.AddClaim(user.Id, new Claim(ClaimTypes.Role, "user"));
userManager.AddClaim(user.Id, new Claim(ClaimTypes.Role, "author"));
userManager.AddClaim(user.Id, new Claim(ClaimTypes.Role, "reviewer"));
userManager.AddClaim(user.Id, new Claim(ClaimTypes.Role, "admin"));
运行后..数据库有用户(在LibraryUser表中)和Claims(在UserClaim表中)
编辑:显示该方法的其余部分......
var userManager = context.OwinContext.GetUserManager<LibraryUserManager>();
LibraryUser user = await userManager.FindAsync(context.UserName, context.Password);
//check if a user exists
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager, OAuthDefaults.AuthenticationType);
AuthenticationProperties properties = CreateProperties(user.UserName, user.DisplayName, oAuthIdentity);
AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
context.Validated(ticket);
创建属性的内容(在上面调用):
public static AuthenticationProperties CreateProperties(string userName, string displayName, ClaimsIdentity oAuthIdentity)
{
IDictionary<string, string> data = new Dictionary<string, string>
{
{ "userName", userName },
{ "displayName", displayName },
{ "roles", string.Join(",", oAuthIdentity.Claims.Where(c => c.Type == ClaimTypes.Role).Select(c => c.Value).ToArray())}
};
return new AuthenticationProperties(data);
}
当用户被authed时..我在LibraryUser.GenerateUserIdentityAsync(上面第1点下的代码)中放置了一个断点,并且CreateIdentityAsync返回的ClaimsIdentity.Claims集合中的唯一声明是默认声明(name,identity_provider) ,security_stamp和另外一个..)..我手动添加的声明不会从数据库返回..
任何人都能看到我错过的东西吗?
如果您需要更多请注释我试图提供所有信息,我会修改我的问题。
提前致谢:D

有冲突的行位于OnModelCreating方法内:
modelBuilder.Entity<LibraryUser>().ToTable("LibraryUser");
modelBuilder.Entity<IdentityUser>().ToTable("LibraryUser"); // <-- this one
由于您使用LibraryUser作为IdentityUser的派生类,因此您无需将IdentityUser显式映射到表。这样做会弄乱数据库中如何生成主键和外键。

声称放入数据库(您在AddClaim()
中执行的操作)并使其包含在令牌中是不同的。您必须手动将声明数据放在继承的OAuthAuthorizationServerProvider
类中,ASP.NET在Provider文件夹或您提供的任何oauth提供程序中提供默认的ApplicatoinOAuthProvider.c。
在那里,覆盖GrantResourceOwnerCredentials()
方法AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
,以便将声明置于令牌中。
然后,Windows Identity将读取您放置的令牌的声明。
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
using (var userManager = _container.GetInstance<ApplicationUserManager>())
{
var user = await userManager.FindAsync(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
ClaimsIdentity oAuthIdentity = await userManager.CreateIdentityAsync(user,
context.Options.AuthenticationType);
ClaimsIdentity cookiesIdentity = await userManager.CreateIdentityAsync(user,
CookieAuthenticationDefaults.AuthenticationType);
AuthenticationProperties properties = CreateProperties(user);
// Below line adds additional claims in token.
AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
context.Validated(ticket);
context.Request.Context.Authentication.SignIn(cookiesIdentity);
}
}
public static AuthenticationProperties CreateProperties(AspNetUser user)
{
IDictionary<string, string> data = new Dictionary<string, string>
{
{"Id", user.Id.ToString(CultureInfo.InvariantCulture)},
{"http://axschema.org/namePerson", user.Nickname,},
{"http://axschema.org/contact/email", user.Email,},
};
return new AuthenticationProperties(data);
}
