谷歌api-安卓如何从authServerCode获取访问令牌

Question

所以这是我的谷歌ApiClient:

 gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestServerAuthCode(serverID)
            .build();
    mGoogleApiClient = new GoogleApiClient.Builder(PSSignInFlowActivity.this)
            .enableAutoManage(this/* FragmentActivity */, this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

这就是当我按下登录按钮时发生的情况：

public void login(){
    Log.i("", "handleSignInResult login:");
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

它把我带到这里：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.i("", "handleSignInResult onActivityResult:" + requestCode + ".." + resultCode);
    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        Log.i("","handleSignInResult onActivityResult: " +result.getSignInAccount() + ",,," + result.getStatus());
        handleSignInResult(result);
    }
}

它称之为：

 private void handleSignInResult(GoogleSignInResult result) {
    Log.i("", "handleSignInResult:" + result.isSuccess());
    if (result.isSuccess()) {
        // Signed in successfully, show authenticated UI.
        GoogleSignInAccount acct = result.getSignInAccount();
        String authCode = acct.getServerAuthCode();
//            if(authCode != null)
//                storyFragment.setFromGoogle(authCode);
    } else {
        // Signed out, show unauthenticated UI.
    }
}

我的问题是我需要一个来自GoogleSignInResult的accessToken，但我只得到了serverAuthCode。我看到你可以在auth2操场上用serverAuthCode交换访问令牌。这可以通过编程实现吗？

这对我有效：

  try{
                    String scope =  "oauth2:" + Scopes.PROFILE;
                    Account account = new Account(acct.getEmail(), "com.google");
                    final String token  = GoogleAuthUtil.getToken(PSSignInFlowActivity.this, account, scope);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            storyFragment.setFromGoogle(token);
                        }
                    });
                }catch (Exception e){
                    Log.e("","error trying to get client secret : " + e.getMessage());
                }
