Google 请求之间未存储 Google 助理位置权限

Google Assistant location permissions not stored between requests

使用 API.AI 和 Google 智能助理,我正在请求获取用户姓名和位置的权限。目的是我可以请求一次许可,后续对我的 Action 的请求将不需要再次请求(因为每次用户与我的 Action 交谈时,这都会导致对话非常生硬)。

我发现我只获得与 actions_intent_PERMISSION 相关的意图中的信息 - 即使我已经授予权限,该信息也不会在其他意图实现中发送. (在下面的示例代码中 - 它最终重新请求所有其他意图的权限。)

我也没有看到在我的操作调用之间维护此权限。因此,每次触发操作时,都会(再次)询问他们是否授予操作权限。

这两种行为看起来都很奇怪。一般而言,应用程序模型不需要我在应用程序调用之间重新授权对资源的权限,甚至在应用程序处于 "running" 时也是如此。甚至网页也会在会话期间保留授权。我做错了什么,还是这是预期的行为?

执行实现的代码(这是 Google Cloud Functions 中的 运行 并且有一些额外的结构通过 Promise 进行这些调用 - 这只是代码)。 res.send(200) 只是向 API.AI 表明它应该使用那里定义的响应,并且可以正常工作。 return Promise.resolve(null); 只是确保不执行其他 fallback/error 条件。


exports.process = function( req, res ){
  var app = new ApiAiApp({request:req, response:res});

  if( app.isPermissionGranted() ){
    res.send( 200 );
    return Promise.resolve( null );
  } else {
    return askPermission( req, res, app );
  }
};

var askPermission = function( req, res, app ){
  //app.tell('foo');
  let namePermission = app.SupportedPermissions.NAME;
  let preciseLocationPermission = app.SupportedPermissions.DEVICE_PRECISE_LOCATION;

  // Ask for more than one permission. User can authorize all or none.
  app.askForPermissions('To address you by name and know your location',
    [namePermission, preciseLocationPermission]);
  return Promise.resolve( null );
};

处理 actions_intent_PERMISSION 请求的 API.AI 意图:

另一个本应具有 user/location 负载但从未使用该信息调用的 Intent

模拟器的屏幕截图表明它总是请求许可,除非特别授予许可:

JSON在请求许可后发送,我已经同意了。正如预期的那样,originalRequest.data.user 有了名称,originalRequest.data.device 现在有了位置。

JSON 在我授予许可(上)后发送,然后发出 "simple test" 短语。请注意,用户和设备字段缺少授予权限的信息,但这是正确的意图。

在两个会话之间执行此操作会产生相同类型的结果。

这是预期的行为。现在我们建议在您的一端保留用户许可的数据,由用户 ID 键入。要了解我们如何建议这样做,请查看 Name Psychic sample. In that sample, we use Firebase Realtime DB 以在 intents/conversations 中为该用户保留许可数据。
