android - UserRecoverableAuthException：需要权限

Question

我尝试按照教程：https ://developers.google.com/android/guides/http-auth 。

代码：

token = GoogleAuthUtil.getToken(getApplicationContext(),
                        mEmail, mScope);

显现：

<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<uses-permission android:name="android.permission.NETWORK"/>
<uses-permission android:name="android.permission.USE_CREDENTIALS"/>
<uses-permission android:name="android.permission.INTERNET"/>

错误：

尝试遵循适用于 Android 的 Drive 快速入门，这是一个分步指南，展示了如何授权和上传文件到 Drive：https ://developers.google.com/drive/quickstart-android

更具体地说，您似乎没有捕获 UserRecoverableException 并触发意图让用户授权应用程序。这记录在您在快速入门示例中链接和处理的 Google Play 服务文档中，如下所示：

...
} catch (UserRecoverableAuthIOException e) {
  startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
}
...

官方 GoogleAuthUtil 教程的 getAndUseAuthTokenBlocking() 方法很好地解释了如何处理异常：

// Example of how to use the GoogleAuthUtil in a blocking, non-main thread context
   void getAndUseAuthTokenBlocking() {
       try {
          // Retrieve a token for the given account and scope. It will always return either
          // a non-empty String or throw an exception.
          final String token = GoogleAuthUtil.getToken(Context, String, String)(context, email, scope);
          // Do work with token.
          ...
          if (server indicates token is invalid) {
              // invalidate the token that we found is bad so that GoogleAuthUtil won't
              // return it next time (it may have cached it)
              GoogleAuthUtil.invalidateToken(Context, String)(context, token);
              // consider retrying getAndUseTokenBlocking() once more
              return;
          }
          return;
       } catch (GooglePlayServicesAvailabilityException playEx) {
         Dialog alert = GooglePlayServicesUtil.getErrorDialog(
             playEx.getConnectionStatusCode(),
             this,
             MY_ACTIVITYS_AUTH_REQUEST_CODE);
         ...
       } catch (UserRecoverableAuthException userAuthEx) {
          // Start the user recoverable action using the intent returned by
          // getIntent()
          myActivity.startActivityForResult(
                  userAuthEx.getIntent(),
                  MY_ACTIVITYS_AUTH_REQUEST_CODE);
          return;
       } 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.
          ...
          return;
       } catch (GoogleAuthException authEx) {
          // Failure. The call is not expected to ever succeed so it should not be
          // retried.
          ...
          return;
       }
   }

我有同样的错误，在我的情况下，我使用了错误的范围，我只是改变

https://www.googleapis.com/auth/plus.login

为了

https://www.googleapis.com/auth/userinfo.profile

在此文档页面 https://developers.google.com/+/mobile/android/sign-in上，该示例对此异常有很好的解释。

特别是，看起来应该注意这一行：

请求授权代码将始终在第一次调用 GoogleAuthUtil.getToken 时抛出 UserRecoverableAuthException

catch (UserRecoverableAuthException e) {
  // Requesting an authorization code will always throw
  // UserRecoverableAuthException on the first call to GoogleAuthUtil.getToken
  // because the user must consent to offline access to their data.  After
  // consent is granted control is returned to your activity in onActivityResult
  // and the second call to GoogleAuthUtil.getToken will succeed.
  startActivityForResult(e.getIntent(), AUTH_CODE_REQUEST_CODE);
  return;
}

我发现这里的答案是被动的解决方案，而不是预防性的。
根据我很短的经验，UserRecoverableAuthException: NeedPermission 会在以下3种情况下抛出：

#1 登录 Google 时未请求适当的范围

检查您请求的范围是否正确。Android 应该通过权限请求对话框要求用户在身份验证过程之后允许权限。这将在调用 API 时防止 UserRecoverableAuthException。

GoogleSignInOptions o = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestScopes(new Scope(DriveScopes.DRIVE)) // request permission for Drive API
            .requestScopes(new Scope(SheetsScopes.SPREADSHEETS)) // request permission for Sheets API
            .requestEmail()
            .build();

#2 用户拒绝了权限

用户在权限请求对话框上按下了“拒绝”按钮。

#3 用户拒绝了您应用的权限

对于 Android 8.1.x，有一个菜单，您可以在其中拒绝个别应用程序的权限。不过，不确定其他版本。

Settings > Google > Connected apps

#2 和 #3 抛出的 UserRecoverableAuthException 是不可避免的，因为它们是用户活动的结果。但是，尽管用户拒绝了，但用下面的代码再次显示权限请求对话框不是没有意义吗？

} catch (UserRecoverableAuthIOException e) {
  startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION);
}

文档最近已更新，现在支持 SDK M（请求权限）并显示 OAuth 对话框。

注意 Google Docs 通常不是最新的，但在您报告问题时它们似乎会引起注意。该示例已更新，我在一周内发送了反馈。因此，如果您看到无效的示例，请发送反馈！
