android - 静默登录成功后能否通过authAccount.getAccessToken()方法获取AccessToken

Question

我正在集成华为帐户套件。我想知道是否可以使用以下代码通过authAccount获取AccessToken:

private void silentSignIn() {
        Task<AuthAccount> task = mAuthManager.silentSignIn();
        task.addOnSuccessListener(new OnSuccessListener<AuthAccount>() {
            @Override
            public void onSuccess(AuthAccount authAccount) {

                Log.i(TAG, "silentSignIn success");
                Log.i(TAG, "touxiang: "+authAccount.getAvatarUriString());
            }
        });
        task.addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(Exception e) {
                //if Failed use getSignInIntent
                if (e instanceof ApiException) {
                    ApiException apiException = (ApiException) e;
                    signIn();
                }
            }
        });
    }

任何人都可以提供任何线索吗？

您可以通过静默登录获得用户级别的AccessToken。

首先你需要检查mAuthManager对象被初始化:

mAuthManager只有满足以下条件时才能初始化对象:

//Call the default constructor of HuaweiIdAuthParamsHelper to set authorization parameters.
AccountAuthParams silentSignInParams = new AccountAuthParamsHelper(AccountAuthParams.DEFAULT_AUTH_REQUEST_PARAM)
        .setAccessToken()
        .createParams();
//Call the getService method of HuaweiIdAuthManager to initialize the HuaweiIdAuthService object.
AccountAuthService mAuthManager = AccountAuthManager.getService(getApplicationContext(), silentSignInParams);
//Call the HuaweiIdAuthService.silentSignIn method to send a silent sign-in request.
Task<AuthAccount> task = mAuthManager.silentSignIn();

AccountAuthParams mAuthManager 时需要对象对象被初始化。创建此对象时，必须设置 .setAccessToken()使用 authHuaweiId.getAccessToken() 获取用户级访问 token 的方法方法。

您可以检查您是否设置了.setAccessToken()方法。
