我正在尝试根据这篇文章获得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,据我所知,我已经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,而我正在使用作用域字符串的服务器(而不是应用程序)ID.我也跟着上面链接中的示例,应用程序工作正常,允许您登录/退出,但我无法获得身份验证代码.
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;
}
