Google Assistant位置权限未存储在请求之间

Pri*_*ner 8 actions-on-google api-ai

使用API​​.AI和Google智能助理,我正在请求获取用户名称和位置的权限.目的是我可以一次请求许可,随后对我的行动的请求将不需要再次询问(因为每次用户与我的行动谈话时,这将导致非常笨拙的对话).

我发现的是,我只是获取与意图相关actions_intent_PERMISSION的信息 - 即使我已经授予了许可,信息也不会在其他意图履行中发送.(在下面的示例代码中 - 它最终会重新请求所有其他意图的权限.)

我也没有在我的Action的调用之间看到这种权限.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.

这两种行为都很奇怪.通常,应用程序模型不要求我在应用程序的调用之间或者甚至在应用程序"运行"时重新授权对资源的许可.甚至网页也会在会话期间保留授权.我做错了什么,或者这是出于预期的行为？

正在执行的代码(这是在Google Cloud Functions中运行的,并且还有一些通过Promise进行这些调用的其他结构 - 这只是代码的相关部分).在res.send(200)刚刚指示API.AI它应该使用被定义有响应,这工作没有任何问题.的return Promise.resolve(null);只是确保在其他备用/错误条件不执行.


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 Intent :

位置结果

另一个应具有用户/位置有效负载的Intent,但永远不会使用该信息调用

简单的测试

模拟器的屏幕截图显示它总是要求许可,除非特别授予它:

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,我们建议您在用户ID的基础上保留用户许可的数据.要了解我们如何推荐这样做,请查看Name Psychic示例.在该示例中,我们使用Firebase Realtime DB在意图/会话中保留该用户的权限数据.

  • 答案已接受,因为它显然是预期的,但虽然这对于很少变化的事情(例如名称)可能是合理的,但缓存设备的位置似乎是不合理的......移动. (4认同)
  • @SachitMishra你打算改变这种行为吗？在我看来,仅授予一次权限并使我们的操作更具上下文感知度将会很棒. (3认同)
  • @SachitMishra 我有点好奇，你知道为什么选择不使用 Android 使用的相同权限模型吗？是否建议如果我们有用户的位置，我们应该不时询问他们是否是最新的？ (2认同)
