Google Assistant位置权限未存储在请求之间

标签： actions-on-google api-ai

使用API​​.AI和Google智能助理，我会请求获取用户姓名和位置的权限。目的是我能够一次请求许可，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，这将导致非常愚蠢的对话）。 / p>

我发现的是，我只是将意图中的信息与actions_intent_PERMISSION绑定在一起 - 即使我已经在其他意图履行中发送了该信息已经获得了许可。 （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的调用之间看到此权限。因此，每次触发操作时，他们都会（再次）询问他们是否授予了操作权限。

这两种行为都很奇怪。通常，应用程序模型不需要我在应用程序的调用之间重新授权对资源的许可，或者甚至在应用程序运行时＃34;。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）。 res.send(200)只是向API.AI表明它应该使用那里定义的响应，并且没有问题。 return Promise.resolve(null);只是确保其他后备/错误条件不会被执行。


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：

Location result

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

simple test

模拟器的屏幕截图显示它总是要求许可，除非特别授予它：

最初连接时发送的JSON：

JSON之后发送的JSON请求许可，我已经授予了它。按预期，originalRequest.data.user有名称，originalRequest.data.device现在有位置。

JSON在我获得许可后发送（上图），然后发出＆＃34;简单测试＆＃34;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this示例。在该示例中，我们使用Name Psychic在意图/会话中保留该用户的权限数据。
