在请求之间未存储Google Assistant位置权限 [英] Google Assistant location permissions not stored between requests
问题描述
我正在使用API.AI和Google助手来获取用户名和位置的权限。目的是我将能够一次请求许可，以后对我的Action的请求将不再需要再次提出请求（因为这将使用户每次与我的Action交谈时都会进行非常严格的对话）。
我发现我只是将意图中的信息与 actions_intent_PERMISSION 绑定在一起-信息是即使我已经授予了许可，也不会发送其他意图。 （在下面的示例代码中，它最终重新请求了所有其他意图的权限。）
我也没有看到在调用两次之间保持该权限。我的行动。因此，每次触发该操作时，都会（再次）询问他们是否授予该操作许可。
这两种行为似乎都很奇怪。通常，应用程序模型不需要我在应用程序调用之间甚至在应用程序运行期间重新授权对资源的许可。甚至网页也可以在会话期间保留授权。我是在做错什么，还是这是预期的行为？
正在执行代码的代码（该代码正在Google Cloud Functions中运行，并且还有一些其他结构正在通过Promise进行这些调用-这只是代码的相关部分）。 res.send（200）只是向API.AI指示它应该使用在那里定义的响应，并且不会出现问题。 返回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）;
返回Promise.resolve（null）;
} else {
return askPermission（req，res，app）;
}
};
var askPermission = function（req，res，app）{
//app.tell(’foo’）;
let namePermission = app.SupportedPermissions.NAME;
let precisionLocationPermission = app.SupportedPermissions.DEVICE_PRECISE_LOCATION;
//请求多个权限。用户可以授权全部或不授权。
app.askForPermissions（按名称称呼您并知道您的位置，
[namePermission，precisionLocationPermission]）；
返回Promise.resolve（null）;
};

在两个会话之间执行此操作会产生相同的结果。
这是预期的行为。目前，我们建议您在用户端保留用户许可的数据，并以用户ID为键。要查看我们建议如何执行此操作，请查看名称Psychic 样本。在该示例中，我们使用 Firebase Realtime DB 持久存储该用户在Intent /对话。
With API.AI and the Google Assistant, I'm requesting permission to get the user's name and location. The intent is that I'll be able to ask for permission once, and subsequent requests to my Action will not need to ask again (since this will make for a very stilted conversation every time the user talks to my Action).
What I am finding is that I'm only getting the information in the intent tied to the actions_intent_PERMISSION - the information isn't sent in other intent fulfillments, even if I've already granted the permission. (In the example code below - it ends up re-requesting permission for all of the other intents.)
I'm also not seeing this permission maintained in between invocations of my Action. So every time the Action is triggered, they're (again) asked if they grant the action permission.
Both behaviors seem odd. Application models, in general, don't require me to re-authorize permission to a resource in between invocations of the application, or even while the application is "running". Even web pages preserve authorization during a session. Am I doing something wrong, or is this the behavior as intended?
Code that is doing the fulfillment (this is running in Google Cloud Functions and there is some additional structure that is making these calls through a Promise - this is just the relevant part of the code). The res.send(200) just indicates to API.AI that it should use the responses that are defined there, and that works without problems. The return Promise.resolve(null); just makes sure that other fallback/error conditions aren't executed.
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 );
};
The API.AI Intent that handles the actions_intent_PERMISSION request:
Another Intent that should have user/location payload, but which never gets called with that info
Screen shot from the Simulator demonstrating it always asks for permission, except when its specifically been granted:

Doing this between two sessions yields the same sort of results.
This is expected behavior. Right now we recommend persisting user permissioned data on your end, keyed by the User ID. To see how we might recommend doing this, check out the Name Psychic sample. In that sample, we use Firebase Realtime DB to persist the permissioned data for that user across intents/conversations.
