Android Google+无法获得授权码
我试图根据这篇文章获得Google+授权码：服务器端访问您的应用程序。 但是，每当我运行我的应用程序并尝试获取代码时，我都会在LogCat中获得以下内容：
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，从我可以告诉的是，我已经在下面的代码中正确安装了所有东西。 任何想法，为什么它没有得到一个身份验证令牌？
仅供参考，我在API控制台中有一个项目设置，该项目同时为oauth配置了应用程序和Web应用程序，并且我正在使用作用域字符串的服务器（而不是应用程序）ID。 我也遵循上述链接中的示例，该应用程序正常工作，并允许您登录/注销，但我无法获得授权码。
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;
}
我不知道你是否修改了这一行来发布这个问题，但看着你发布的代码，这一行是错误的：
String scopes = "oauth2:server:client_id:<My server client ID>:scopesString";
它应该是：
String scopes = "oauth2:server:client_id:" + SERVER_CLIENT_ID + ":api_scope:" + scopeString;
尝试这个，
在你onCreate（）写入，
new GetTokenAsync.execute();
然后编写AsyncTask来获取访问令牌，
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();
}
}
