Web API 2 OWIN承载令牌认证
我有一个现有的ASP.NET MVC 5项目，我正在为它添加一个Web API 2项目。 我想使用不记名令牌认证，并且遵循了Hongye Sun的教程“使用Web API示例的OWIN承载令牌认证”以及此问题。
在我的Login方法中，对于Startup.OAuthBearerOptions.AccessTokenFormat.Protect(ticket); ， AccessTokenFormat为空。 任何想法为什么？
我的AccountController ：
[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);
}
}
启动课程：
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模板中获得了这个，只有GrantResourceOwnerCredentials已被更改）：
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
}
}
MyWebOAuthGrantResourceOwnerCredientialsContext ：
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如何设置？ 我设定的正确吗？ 我没有对任何外部服务进行身份验证，只是传统的内部服务器。 谢谢。
我遇到了同样的问题 - 这与我在Startup（）中的初始化有关。
和你一样，我将OAuthBearerOptions存储在一个静态字段中：
OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
但后来我错误地使用了同一个类的新实例：
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions()); // wrong!
显然，解决方法是使用静态字段：
app.UseOAuthBearerAuthentication(OAuthBearerOptions);
实际上，它看起来并不像调用UseOAuthBearerAuthentication（）。 我遵循了Taiseer Joudeh撰写的这一系列杰出的文章。
完整的Startup.cs：
public class Startup
{
public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }
public void Configuration(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
ConfigureOAuth(app);
WebApiConfig.Register(config);
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWebApi(config);
}
public void ConfigureOAuth(IAppBuilder app)
{
//use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseExternalSignInCookie(Microsoft.AspNet.Identity.DefaultAuthenticationTypes.ExternalCookie);
OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions() {
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new SimpleAuthorizationServerProvider() // see post
};
// Token Generation
app.UseOAuthAuthorizationServer(OAuthServerOptions);
app.UseOAuthBearerAuthentication(OAuthBearerOptions);
//[Configure External Logins...]
}
}
我不确定你是否仍然在寻找这个答案 - 但是这里有一些代码用于我的AngularJS应用程序从我的WebAPI2端点获取安全令牌。
$http({
method: 'POST', url: '/token', data: { username: uName, password: uPassword, grant_type: 'password' },
transformRequest: function (obj) {
var str = [];
for (var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
}
}).success(function (data, status, headers, config) {
console.log("http success", data);
accessToken.value = data.access_token;
console.log("access token = ", accessToken.value);
}).error(function (data, status, headers, config) {
console.log("http error", data);
});
然后，我可以在任何其他请求的头部中传递accessToken以获得身份验证。
我已经删除了示例代码，因为它在与Web API和SPA模板一起使用时会造成混淆。 您最好使用模板代码来使用OAuth授权服务器来生成令牌。 在您的方案中，您应该使用资源所有者密码授权来验证用户身份。 请在http://blogs.msdn.com/b/webdev/archive/2013/09/20/understanding-security-features-in-spa-template.aspx上查看我的博客，其中包含有关密码流的详细信息
您不必编写自己的Web API来处理登录，而需要使用OWIN OAuth服务器的/令牌端点来处理密码登录。
