只需在服务器端创建身份验证令牌并将其存储在您的数据库甚至缓存中。然后将此令牌与来自您的 win forms 应用程序的请求一起发送。WebApi 应该一直检查这个令牌。这已经足够好了,您可以完全控制您的身份验证过程。
让我分享一下,它是如何为我工作的:
带有 Auth 详细信息的对象:
public class TokenIdentity
{
public int UserID { get; set; }
public string AuthToken { get; set; }
public ISocialUser SocialUser { get; set; }
}
Web API 验证控制器:
public class AuthController : ApiController
{
public TokenIdentity Post(
SocialNetwork socialNetwork,
string socialUserID,
[FromUri]string socialAuthToken,
[FromUri]string deviceRegistrationID = null,
[FromUri]DeviceType? deviceType = null)
{
var socialManager = new SocialManager();
var user = socialManager.GetSocialUser(socialNetwork, socialUserID, socialAuthToken);
var tokenIdentity = new AuthCacheManager()
.Authenticate(
user,
deviceType,
deviceRegistrationID);
return tokenIdentity;
}
}
身份验证缓存管理器:
public class AuthCacheManager : AuthManager
{
public override TokenIdentity CurrentUser
{
get
{
var authToken = HttpContext.Current.Request.Headers["AuthToken"];
if (authToken == null) return null;
if (HttpRuntime.Cache[authToken] != null)
{
return (TokenIdentity) HttpRuntime.Cache.Get(authToken);
}
return base.CurrentUser;
}
}
public int? CurrentUserID
{
get
{
if (CurrentUser != null)
{
return CurrentUser.UserID;
}
return null;
}
}
public override TokenIdentity Authenticate(
ISocialUser socialUser,
DeviceType? deviceType = null,
string deviceRegistrationID = null)
{
if (socialUser == null) throw new ArgumentNullException("socialUser");
var identity = base.Authenticate(socialUser, deviceType, deviceRegistrationID);
HttpRuntime.Cache.Add(
identity.AuthToken,
identity,
null,
DateTime.Now.AddDays(7),
Cache.NoSlidingExpiration,
CacheItemPriority.Default,
null);
return identity;
}
}
授权经理:
public abstract class AuthManager
{
public virtual TokenIdentity CurrentUser
{
get
{
var authToken = HttpContext.Current.Request.Headers["AuthToken"];
if (authToken == null) return null;
using (var usersRepo = new UsersRepository())
{
var user = usersRepo.GetUserByToken(authToken);
if (user == null) return null;
return new TokenIdentity
{
AuthToken = user.AuthToken,
SocialUser = user,
UserID = user.ID
};
}
}
}
public virtual TokenIdentity Authenticate(
ISocialUser socialUser,
DeviceType? deviceType = null,
string deviceRegistrationID = null)
{
using (var usersRepo = new UsersRepository())
{
var user = usersRepo.GetUserBySocialID(socialUser.SocialUserID, socialUser.SocialNetwork);
user = (user ?? new User()).CopyFrom(socialUser);
user.AuthToken = System.Guid.NewGuid().ToString();
if (user.ID == default(int))
{
usersRepo.Add(user);
}
usersRepo.SaveChanges();
return new TokenIdentity
{
AuthToken = user.AuthToken,
SocialUser = user,
UserID = user.ID
};
}
}
}
全局操作过滤器:
public class TokenAuthenticationAttribute : System.Web.Http.Filters.ActionFilterAttribute
{
public override void OnActionExecuting(System.Web.Http.Controllers.HttpActionContext actionContext)
{
if (actionContext.Request.RequestUri.AbsolutePath.Contains("api/auth"))
{
return;
}
var authManager = new AuthCacheManager();
var user = authManager.CurrentUser;
if (user == null)
{
throw new HttpResponseException(HttpStatusCode.Unauthorized);
}
//Updates the authentication
authManager.Authenticate(user.SocialUser);
}
}
Global.asax 注册:
GlobalConfiguration.Configuration.Filters.Add(new AuthFilterAttribute());
这个想法是 AuthCacheManager 扩展 AuthManager 并装饰它的方法和属性。如果缓存内没有任何内容,请检查数据库。
