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） .
我发现的是，我只是将意图中的信息与 actions_intent_PERMISSION 相关联 - 信息已经被授予了许可 . （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） . 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); 只是确保不执行其他回退/错误条件 .
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 Intent：
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
模拟器的屏幕截图显示它总是要求许可，除非特别授予它：

JSON发送后请求许可，我已经批准了 . 正如预期的那样 originalRequest.data.user 有名称， originalRequest.data.device 现在有位置 .

在我获得许可（上面）后发送JSON，然后发出“简单测试”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Name Psychic样本 . 在该示例中，我们使用Firebase Realtime DB在意图/对话中持久保存该用户的权限数据 .
