Question

我正在尝试根据这篇文章获取Google+身份验证代码：Server-side access for your app。但是，每当我运行我的应用程序并尝试获取代码时，我在LogCat中得到以下内容：

07-23 23:42:31.760: E/getAccessToken()(11114): [ERROR] GoogleAuthException: com.google.android.gms.auth.GoogleAuthException: Unknown

我浏览了很多东西，据我所知，我在下面的代码中正确设置了所有内容。任何想法为什么它没有获得身份验证令牌？

仅供参考，我在API控制台中有一个项目设置，其中包含为oauth配置的应用程序和Web应用程序，我正在使用作用域字符串的服务器（而不是应用程序）ID。我也按照上面的链接中的示例进行操作，该应用程序工作正常并允许您登录/退出，但我无法获取身份验证代码。

private String getAccessToken() {
    String scopesString = Scopes.PLUS_LOGIN + " " + Scopes.PLUS_PROFILE;
    String scope = "oauth2:server:client_id:" + SERVER_CLIENT_ID + ":api_scope:" + scopesString;
    Bundle appActivities = new Bundle();
    appActivities.putString(GoogleAuthUtil.KEY_REQUEST_VISIBLE_ACTIVITIES,
            "http://schemas.google.com/AddActivity");
    String code = null;
    try {
         code = GoogleAuthUtil.getToken(
                    this,                             // Context context
                    mPlusClient.getAccountName(),     // String accountName
                    scopes,                           // String scope
                    appActivities                     // Bundle bundle
                );
    } catch (IOException transientEx) {
      // network or server error, the call is expected to succeed if you try again later.
      // Don't attempt to call again immediately - the request is likely to
      // fail, you'll hit quotas or back-off.
        Log.e("getAccessToken()", "[ERROR] IOException: " + transientEx);
        return null;
    } catch (UserRecoverableAuthException e) {
           // Recover
        Log.e("getAccessToken()", "[ERROR] UserRecoverableAuthException: " + e);
        code = null;
    } catch (GoogleAuthException authEx) {
      // Failure. The call is not expected to ever succeed so it should not be
      // retried.
        Log.e("getAccessToken()", "[ERROR] GoogleAuthException: " + authEx);
      return null;
    } catch (Exception e) {
        Log.e("getAccessToken()", "[ERROR] Exception: " + e);
      throw new RuntimeException(e);
    }
    return code;
}

试试这个，

你在onCreate（）上写

，

new GetTokenAsync.execute();

然后编写AsyncTask以获取访问令牌，

public class GetTokenAsync extends AsyncTask<String, String, String>
        {

            @Override
            protected void onPreExecute()
                {

                    super.onPreExecute();
                    plusUtilities.ShowProgressDialog("Getting Token...");

                }

            @Override
            protected String doInBackground(String... params)
                {
                    String scope = "oauth2:" + Scopes.PLUS_LOGIN + " " + Scopes.PLUS_PROFILE;
                    try
                        {
                            // We can retrieve the token to check via
                            // tokeninfo or to pass to a service-side
                            // application.
                            String token = GoogleAuthUtil.getToken(getParent(), mPlusClient.getAccountName(), scope);
                            Log.i("OAUTH Token:", token);
                            Log.i("Scope:", "" + scope);
                            Log.i("GOOGLE_ACCOUNT_TYPE", "" + GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);

                            Person currentperson = mPlusClient.getCurrentPerson();
                               Log.i("person", currentperson.toString());

                        }
                    catch (UserRecoverableAuthException e)
                        {
                            Log.e("UserRecoverableAuthException", "UserRecoverableAuthException");
                            e.printStackTrace();
                        }
                    catch (IOException e)
                        {
                            Log.e("IOException", "IOException");
                            e.printStackTrace();
                        }
                    catch (GoogleAuthException e)
                        {
                            Log.e("GoogleAuthException", "GoogleAuthException");
                            e.printStackTrace();
                        }
                    catch (Exception e)
                        {
                            Log.e("Exception", "Exception");
                            e.printStackTrace();
                        }
                    return null;
                }

            @Override
            protected void onPostExecute(String result)
                {

                    super.onPostExecute(result);
                    plusUtilities.DissmissProgressDialog();
                }

        }

我不知道您是否修改过该行以发布问题，但查看您发布的代码，这一行是错误的：

String scopes = "oauth2:server:client_id:<My server client ID>:scopesString";

应该是：

String scopes = "oauth2:server:client_id:" + SERVER_CLIENT_ID + ":api_scope:" + scopeString;

Android Google+无法获取授权码
