我使用Azure Active Directory(AAD)设置了一个简单的MVC应用程序.
我需要查询AAD Graph API,以便从我的应用程序管理应用程序角色和组.
在Startup类中,我收到了类似的AccessToken:
public void ConfigureAuth(IAppBuilder app)
{
AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = Constants.ClientId,
Authority = Constants.Authority,
PostLogoutRedirectUri = Constants.PostLogoutRedirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications()
{
// If there is a code in the OpenID Connect response, redeem it for an access token and refresh token, and store those away.
AuthorizationCodeReceived = (context) =>
{
var code = context.Code;
var credential = new ClientCredential(Constants.ClientId, Constants.ClientSecret);
var signedInUserId =
context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
var authContext = new AuthenticationContext(Constants.Authority,
new TokenDbCache(signedInUserId));
var result = authContext.AcquireTokenByAuthorizationCode(
code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential,
Constants.GraphUrl);
var accessToken = result.AccessToken;
return Task.FromResult(0);
}
}
});
}
要实例化ActiveDirectoryClient类,我需要传递AccessToken:
var servicePointUri = new Uri("https://graph.windows.net");
var serviceRoot = new Uri(servicePointUri, tenantID);
var activeDirectoryClient = new ActiveDirectoryClient(serviceRoot,
async () => await GetTokenForApplication());
我想知道将AccessToken存储为声明是否是一个很好的解决方案(在Startup类中添加行)?
context.AuthenticationTicket.Identity.AddClaim(new
Claim("OpenId_AccessToken", result.AccessToken));
EDIT令牌已存储..
得到它 !!!谢谢乔治.
所以我的Token已经使用TokenDbCache类存储在数据库中.
根据样本再次(在我的一个控制器中)获取它:
public async Task<string> GetTokenForApplication()
{
string signedInUserID = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
string tenantID = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/tenantid").Value;
string userObjectID = ClaimsPrincipal.Current.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier").Value;
// get a token for the Graph without triggering any user interaction (from the cache, via multi-resource refresh token, etc)
ClientCredential clientcred = new ClientCredential(clientId, appKey);
// initialize AuthenticationContext with the token cache of the currently signed in user, as kept in the app's database
AuthenticationContext authenticationContext = new AuthenticationContext(aadInstance + tenantID, new TokenDbCache<ApplicationDbContext>(signedInUserID));
AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenSilentAsync(graphResourceID, clientcred, new UserIdentifier(userObjectID, UserIdentifierType.UniqueId));
return authenticationResult.AccessToken;
}
从AuthenticationContext我不知道的事情:
如果已经请求了令牌,它将从TokenDbCache中检索它.
最佳答案 当您通过Adal检索令牌时,它会在NaiveCache对象中缓存它.
使用StartUp类检索令牌的代码:
AuthenticationResult kdAPiresult = authContext.AcquireTokenByAuthorizationCode(code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, "Your API Resource ID");
string kdAccessToken = kdAPiresult.AccessToken;
在Azure Active Directory示例(https://github.com/AzureADSamples)中,此对象用于在app控制器中检索令牌.您可以实现自己的缓存以相同的方式检索它.
在控制器代码中,您可以执行以下操作:
IOwinContext owinContext = HttpContext.GetOwinContext();
string userObjectID = owinContext.Authentication.User.Claims.First(c => c.Type == Configuration.ClaimsObjectidentifier).Value;
NaiveSessionCache cache = new NaiveSessionCache(userObjectID);
AuthenticationContext authContext = new AuthenticationContext(Configuration.Authority, cache);
TokenCacheItem kdAPITokenCache = authContext.TokenCache.ReadItems().Where(c => c.Resource == "You API Resource ID").FirstOrDefault();
如果您正在获取令牌而不是AuthenticationContext(3d party apis),您也可以将令牌存储在声明中
