我有一个现有的 ASP.NET MVC 5 项目，我正在向它添加一个 Web API 2 项目。我想使用不记名令牌身份验证，并遵循了 Hongye Sun 的教程“OWIN Bearer Token Authentication with Web API Sample”和这个问题。
在我的Login方法中，对于 line Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket);，AccessTokenFormat为空。知道为什么吗？
我的帐户控制器：
[RoutePrefix("api")]
public class AccountController : ApiController
{
public AccountController() {}
// POST api/login
[HttpPost]
[Route("login")]
public HttpResponseMessage Login(int id, string pwd)
{
if (id > 0) // testing - not authenticating right now
{
var identity = new ClaimsIdentity(Startup.OAuthBearerOptions.AuthenticationType);
identity.AddClaim(new Claim(ClaimTypes.Name, id.ToString()));
AuthenticationTicket ticket = new AuthenticationTicket(identity, new AuthenticationProperties());
var currentUtc = new SystemClock().UtcNow;
ticket.Properties.IssuedUtc = currentUtc;
ticket.Properties.ExpiresUtc = currentUtc.Add(TimeSpan.FromMinutes(30));
var token = Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket);
return new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new ObjectContent<object>(new
{
UserName = id.ToString(),
AccessToken = token
}, Configuration.Formatters.JsonFormatter)
};
}
return new HttpResponseMessage(HttpStatusCode.BadRequest);
}
// POST api/token
[Route("token")]
[HttpPost]
public HttpResponseMessage Token(int id, string pwd)
{
// Never reaches here. Do I need this method?
return new HttpResponseMessage(HttpStatusCode.OK);
}
}
启动类：
public class Startup
{
private static readonly ILog _log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }
public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }
public static Func<MyUserManager> UserManagerFactory { get; set; }
public static string PublicClientId { get; private set; }
static Startup()
{
PublicClientId = "MyWeb";
UserManagerFactory = () => new MyUserManager(new UserStore<MyIdentityUser>());
OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/api/token"),
Provider = new MyWebOAuthProvider(PublicClientId, UserManagerFactory),
AuthorizeEndpointPath = new PathString("/api/login"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
AllowInsecureHttp = true
};
}
public void Configuration(IAppBuilder app)
{
// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/api/login")
});
// Configure Web API to use only bearer token authentication.
var config = GlobalConfiguration.Configuration;
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(OAuthBearerOptions.AuthenticationType));
app.UseWebApi(config);
}
}
MyIdentityUser只是添加了一个额外的属性：
public class MyIdentityUser : IdentityUser
{
public int SecurityLevel { get; set; }
}
MyUserManager将我的自定义用户身份验证方法调用到内部服务器：
public class MyUserManager : UserManager<MyIdentityUser>
{
public MyUserManager(IUserStore<MyIdentityUser> store) : base(store) { }
public MyIdentityUser ValidateUser(int id, string pwd)
{
LoginIdentityUser user = null;
if (MyApplication.ValidateUser(id, pwd))
{
// user = ??? - not yet implemented
}
return user;
}
}
MyWebOAuthProvider（我从 SPA 模板中获取了这个。仅GrantResourceOwnerCredentials已更改）：
public class MyWebOAuthProvider : OAuthAuthorizationServerProvider
{
private readonly string _publicClientId;
private readonly Func<MyUserManager> _userManagerFactory;
public MyWebOAuthProvider(string publicClientId, Func<MyUserManager> userManagerFactory)
{
if (publicClientId == null)
{
throw new ArgumentNullException("publicClientId");
}
if (userManagerFactory == null)
{
throw new ArgumentNullException("userManagerFactory");
}
_publicClientId = publicClientId;
_userManagerFactory = userManagerFactory;
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
using (MyUserManager userManager = _userManagerFactory())
{
MyIdentityUser user = null;
var ctx = context as MyWebOAuthGrantResourceOwnerCredentialsContext;
if (ctx != null)
{
user = userManager.ValidateUser(ctx.Id, ctx.Pwd);
}
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.UserName);
AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
context.Validated(ticket);
context.Request.Context.Authentication.SignIn(cookiesIdentity);
}
}
public override Task TokenEndpoint(OAuthTokenEndpointContext context)
{
... // unchanged from SPA template
}
public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
{
... // unchanged from SPA template
}
public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
{
... // unchanged from SPA template
}
public static AuthenticationProperties CreateProperties(string userName)
{
... // unchanged from SPA template
}
}
MyWebOAuthGrantResourceOwnerCredentialsContext：
public class MyWebOAuthGrantResourceOwnerCredentialsContext : OAuthGrantResourceOwnerCredentialsContext
{
public MyWebOAuthGrantResourceOwnerCredentialsContext (IOwinContext context, OAuthAuthorizationServerOptions options, string clientId, string userName, string password, IList<string> scope)
: base(context, options, clientId, userName, password, scope)
{ }
public int Id { get; set; }
public string Pwd { get; set; }
}
AccessTokenFormat是如何设置的？我设置的是否正确？我没有针对任何外部服务进行身份验证，只是对旧的内部服务器进行身份验证。谢谢。
