使用OWin中间件和IdentityServer v3刷新令牌 [英] Refresh tokens using owin middleware and IdentityServer v3
问题描述
我最近设置了IdentityServer v3，它的运行就像梦一样，但是我在使用OWIN中间件时遇到了麻烦.
I've recently setup IdentityServer v3 and its running like a dream, however I'm having troubles with the OWIN middleware.
我想使用混合流，这样我就可以在后端刷新令牌，而用户不必每5分钟重定向回到IdentityServer以获取一个新的访问令牌(这对于设置有生存期的用户来说也很奇怪在服务器上1小时).
I would like to use the hybrid flow so I can refresh tokens in the backend without the user having to redirect back to the IdentityServer to get a new access token every 5 minutes (which is also odd as its set to have a lifetime of 1 hour on the server).
我在启动时使用以下配置，并且使令牌正常运行，但是似乎永远不会尝试在访问令牌过期后刷新访问令牌.我是否需要一些自定义逻辑来刷新令牌?
I'm using the following config in startup and I'm getting the tokens fine, but it never seems to try and refresh the access token once it's expired. Do I need some custom logic somewhere to refresh my tokens?
app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
ClientSecret = clientSecret, //Not sure what this does?
Authority = "https://auth.example.com",
RedirectUri = "http://website.example.com",
PostLogoutRedirectUri = "http://website.example.com",
ResponseType = "code id_token token",
Scope = "openid profile email write read offline_access",
SignInAsAuthenticationType = "Cookies",
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthorizationCodeReceived = async n =>
{
// filter "protocol" claims
var claims = new List<Claim>(from c in n.AuthenticationTicket.Identity.Claims
where c.Type != "iss" &&
c.Type != "aud" &&
c.Type != "nbf" &&
c.Type != "exp" &&
c.Type != "iat" &&
c.Type != "nonce" &&
c.Type != "c_hash" &&
c.Type != "at_hash"
select c);
// get userinfo data
var userInfoClient = new UserInfoClient(
new Uri(n.Options.Authority + "/connect/userinfo"),
n.ProtocolMessage.AccessToken);
var userInfo = await userInfoClient.GetAsync();
userInfo.Claims.ToList().ForEach(ui => claims.Add(new Claim(ui.Item1, ui.Item2)));
// get access and refresh token
var tokenClient = new OAuth2Client(
new Uri(n.Options.Authority + "/connect/token"),
clientId,
clientSecret);
var response = await tokenClient.RequestAuthorizationCodeAsync(n.Code, n.RedirectUri);
claims.Add(new Claim("access_token", response.AccessToken));
claims.Add(new Claim("expires_at", DateTime.UtcNow.AddSeconds(response.ExpiresIn).ToLocalTime().ToString(CultureInfo.InvariantCulture)));
claims.Add(new Claim("refresh_token", response.RefreshToken));
claims.Add(new Claim("id_token", n.ProtocolMessage.IdToken));
//Does this help?
n.AuthenticationTicket.Properties.AllowRefresh = true;
n.AuthenticationTicket = new AuthenticationTicket(
new ClaimsIdentity(
claims.Distinct(new ClaimComparer()),
n.AuthenticationTicket.Identity.AuthenticationType),
n.AuthenticationTicket.Properties);
},
RedirectToIdentityProvider = async n =>
{
// if signing out, add the id_token_hint
if (n.ProtocolMessage.RequestType == OpenIdConnectRequestType.LogoutRequest)
{
var id = n.OwinContext.Authentication.User.FindFirst("id_token");
if (id != null)
{
var idTokenHint = id.Value;
n.ProtocolMessage.IdTokenHint = idTokenHint;
}
}
}
}
});
我还在ApiClient(RestSharp)中使用以下内容，该内容与我的资源api对话
I'm also using the following in my ApiClient (RestSharp) which talks to my resource api
public class MyTokenAuthenticator : IAuthenticator
{
public void Authenticate(IRestClient client, IRestRequest request)
{
var tokenClaim = ClaimsPrincipal.Current.Claims.FirstOrDefault(c => c.Type.Equals("access_token"));
if (tokenClaim != null && !String.IsNullOrWhiteSpace(tokenClaim.Value))
request.AddHeader("Authorization", String.Format("Bearer {0}", tokenClaim.Value));
}
}
推荐答案
我能够获取刷新令牌，然后使用它来获取新的访问令牌:我遵循了与您类似的逻辑来获得令牌.我创建了以下每次需要令牌时都会调用的方法:
I was able to get a refresh token and then use it to get a new access token: I followed similar logic as yours to get a token. I created the following method which I called every time I needed a token:
private static async Task CheckAndPossiblyRefreshToken(ClaimsIdentity id)
{
var clientName = "Myhybridclient";
// check if the access token hasn't expired.
if (DateTime.Now.ToLocalTime() >=
(DateTime.Parse(id.FindFirst("expires_at").Value)))
{
// expired. Get a new one.
var tokenEndpointClient = new OAuth2Client(
new Uri(Constants.TokenEndpoint),
clientName,
"secret");
var tokenEndpointResponse =
await tokenEndpointClient
.RequestRefreshTokenAsync(id.FindFirst("refresh_token").Value);
if (!tokenEndpointResponse.IsError)
{
// replace the claims with the new values - this means creating a
// new identity!
var result = from claim in id.Claims
where claim.Type != "access_token" && claim.Type != "refresh_token" &&
claim.Type != "expires_at"
select claim;
var claims = result.ToList();
claims.Add(new Claim("access_token", tokenEndpointResponse.AccessToken));
claims.Add(new Claim("expires_at",
DateTime.Now.AddSeconds(tokenEndpointResponse.ExpiresIn)
.ToLocalTime().ToString()));
claims.Add(new Claim("refresh_token", tokenEndpointResponse.RefreshToken));
var newIdentity = new ClaimsIdentity(claims, "Cookies");
var wrapper = new HttpRequestWrapper(HttpContext.Current.Request);
wrapper.GetOwinContext().Authentication.SignIn(newIdentity);
}
else
{
// log, ...
throw new Exception("An error has occurred");
}
}
}
