[英]Always get “Authorization has been denied for this request.” using Bearer tokens in Identity 2?
使用邮递员,我可以请求令牌,这里是:
{
"access_token": "N1FL606bmDkZyLplpkLAihaviMQhB042z-rhY262M_W5nSWIv8fDOQiYkEn6GCuDnrxpdOWBS7lpxlBazHYlwnP1RvpDFED1i_ml89QNspyGOWB6TcMkT1MmfUAZ617k9MNvl5UJh2jKzUwvDDeXMURG9tEtmE3UX2L2D-1VA9kqYOzOB1UYbpMAfdTi84jsbR0lhLkNkReQ5fqg4B3IFbbWNGWu5ONb1uuf00ixL-BIMqSvEaNn58_zCyAVFWVzcH2tayYTGT5p_AItKfYiWaYHKC0pDoZ_OBdlpB7Odc7ScwjwFM5vtpBZE81rpk8yjXnrTEk_j9n0eiloJnpWwA",
"token_type": "bearer",
"expires_in": 899,
"refresh_token": "60da311d10f043b892c703c7fb7ab061",
"as:client_id": "Erp",
"userName": "bbauer",
".issued": "Tue, 30 Jun 2015 17:56:10 GMT",
".expires": "Tue, 30 Jun 2015 18:11:10 GMT"
}
我还可以从不受保护的资源中获取信息,例如: http:// localhost:60689 / api / Accounts / User / bbauer
{
"url": "http://localhost:60689/api/accounts/user/31",
"id": 31,
"userName": "bbauer",
"fullName": "Brian Bauer",
"email": null,
"emailConfirmed": false,
"roles": [
"Administrator"
],
"claims": []
}
由此可见,该用户处于“管理员”角色。 当我尝试获取受保护的资源时,我总是会找回此信息: “此请求的授权已被拒绝。”
这是控制器中的方法:
[Authorize(Roles = "Administrator")]
[Route("user/{id:int}", Name = "GetUserById")]
public async Task<IHttpActionResult> GetUser(int id)
{
var user = await AppUserManager.FindByIdAsync(id);
if (user != null)
{
return Ok(TheModelFactory.Create(user));
}
return NotFound();
}
这是我在邮递员中的设置: http:// localhost:60689 / api / Accounts / User / 31
内容类型: application / json
接受: application / json
授权:承载N1FL606bmDkZyLplpkLAihaviMQhB042z-rhY262M_W5nSWIv8fDOQiYkEn6GCuDnrxpdOWBS7lpxlBazHYlwnP1RvpDFED1i_ml89QNspyGOWB6TcMkT1MmfUAZ617k9MNvl5UJh2jKzUwvDDeXMURG9tEtmE3UX2L2D-1VA9kqYOzOB1UYbpMAfdTi84jsbR0lhLkNkReQ5fqg4B3IFbbWNGWu5ONb1uuf00ixL-BIMqSvEaNn58_zCyAVFWVzcH2tayYTGT5p_AItKfYiWaYHKC0pDoZ_OBdlpB7Odc7ScwjwFM5vtpBZE81rpk8yjXnrTEk_j9n0eiloJnpWwA
我可以使用提琴手来验证正在发送授权标头。 还要注意的另一件事是,当我传递access_token来获取不受保护的/ user / username资源时,我可以中断代码并使用以下设置查看ClaimsPrincipal:
AuthenticationType:承载
IsAuthenticated: true
姓名: bbauer
但是,如果我测试User.IsInRole(“ Administrator”),则它始终为false。 为什么是假的? AspNetUserRole表具有该条目,当我获取用户时,我看到他的“管理员”角色……在这里,上帝的绿色世界上我想念的是什么?
这是我的启动类,如果有帮助的话:
public class Startup
{
public static OAuthAuthorizationServerOptions OAuthServerOptions { get; private set; }
public static OAuthBearerAuthenticationOptions OAuthBearerOptions { get; private set; }
public static string PublicClientId { get; private set; }
public void Configuration(IAppBuilder app)
{
var httpConfig = new HttpConfiguration();
ConfigureOAuth(app);
WebApiConfig.Register(httpConfig);
app.UseCors(CorsOptions.AllowAll);
app.UseWebApi(httpConfig);
}
public void ConfigureOAuth(IAppBuilder app)
{
// Configure the db context and user manager to use a single instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);
PublicClientId = "self";
OAuthServerOptions = new OAuthAuthorizationServerOptions
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/Token"),
AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(15),
Provider = new SimpleAuthorizationServerProvider(PublicClientId),
RefreshTokenProvider = new SimpleRefreshTokenProvider(),
};
app.UseOAuthAuthorizationServer(OAuthServerOptions);
OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
app.UseOAuthBearerAuthentication(OAuthBearerOptions);
}
}
事实证明,我需要在SimpleAuthorizationServerProvider的GrantResourceOwnerCredentials方法中向我的ClaimsIdentity添加角色。 这是代码(请参阅注释部分):
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
var allowedOrigin = context.OwinContext.Get<string>("as:clientAllowedOrigin") ?? "*";
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { allowedOrigin });
var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
ApplicationUser user = await userManager.FindAsync(context.UserName, context.Password);
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
identity.AddClaim(new Claim(ClaimTypes.Name, context.UserName));
identity.AddClaim(new Claim("sub", context.UserName));
//this loop is where the roles are added as claims
foreach (var role in userManager.GetRoles(user.Id))
{
identity.AddClaim(new Claim(ClaimTypes.Role, role));
}
var props = new AuthenticationProperties(new Dictionary<string, string>
{
{
"as:client_id", context.ClientId ?? string.Empty
},
{
"userName", context.UserName
}
});
var ticket = new AuthenticationTicket(identity, props);
context.Validated(ticket);
}
