Cognito Google 联合身份，无效的 OpenId Connect 身份令牌

Question

我正在开发一个应用程序，该应用程序允许用户使用他们的 google 帐户登录，然后使用该登录名获取 Cognito 联合身份。

我无法获得使用 Cognito 进行身份验证所需的正确令牌。我不断收到错误com.amazonaws.services.cognitoidentity.model.NotAuthorizedException: Invalid login token. Not a valid OpenId Connect identity token.

这是我的代码：

        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                CognitoSyncClientManager.init(getActivity().getApplicationContext());

                String token = null;

                try {
                    token = GoogleAuthUtil.getToken(getActivity().getApplicationContext(), signInAccount.getAccount(), "oauth2:openid");
                }catch (Exception e){
                    Log.d("login exception", e.toString());
                }
                Map<String, String> logins = new HashMap<String, String>();
                logins.put("accounts.google.com", token);
                CognitoSyncClientManager.addLogins("accounts.google.com", token);
                Log.d("login", "Created User token " + token);
                Log.d("login", "Cached UserID: "+CognitoSyncClientManager.credentialsProvider.getCachedIdentityId());
                Log.d("login", "UserID: " + CognitoSyncClientManager.credentialsProvider.getIdentityId());
                Toast.makeText(getActivity().getApplicationContext(), "Created user: "+CognitoSyncClientManager.credentialsProvider.getCachedIdentityId(), Toast.LENGTH_LONG);
            }
        };
        Thread t = new Thread(runnable);
        t.start();

GoogleAuthUtil 的 getToken 似乎返回一个访问令牌。

https://developers.google.com/android/reference/com/google/android/gms/auth/GoogleAuthUtil.html#getToken(android.content.Context , android.accounts.Account, java.lang.String, android. os.Bundle)

您需要将 Google 的 OpenId Connect Id 令牌传递给 Cognito 而不是访问令牌。
