在dialogflow Webhook请求中将设备位置获取为空 [英] Getting device location as empty in dialogflow webhook request

问题描述

我正在尝试通过请求权限来获取用户的设备位置。它对模拟器很好用，但是当我用google mini设备进行测试时，webhook请求中的设备位置未定义。下面是代码

Hi i'm trying to get device location of the user by asking permission.It works fine for simulator but when i tested with google mini device getting undefined for device location in webhook request.Below is the code

const {Permission} = require('actions-on-google');
const {WebhookClient} = require('dialogflow-fulfillment');
const agent = new WebhookClient({ request: req, response: res });
conv.ask(new Permission({context:'To Locate You',permissions:'DEVICE_COARSE_LOCATION'}));
function userinfo(agent){
        var conv=agent.conv();
        var resp=conv.arguments.get('PERMISSION');
    console.log(conv.device.location);
    if(resp){

                var country=conv.device.location.country;
                var speech="you are located in "+country;
                conv.ask(speech);
                agent.add(conv);
        }else{
            conv.ask('Sorry, I could not figure out where you are');
            agent.add(conv);
    }
}

推荐答案

您不能混合使用对话流实现和 google-actions 库。数据类型不一定要兼容。如果您需要特定于Google Actions的功能，则应完全使用 googles上的动作。如果您需要Dialogflow支持的多种平台之间的兼容性，请使用 dialogflow-fulfillment 。

You can't mix the dialogflow-fulfillment and actions-on-google libraries. The data types aren't necessarily going to be compatible. If you require features specific to Actions on Google, you should use actions-on-google completely. If you require compatibility between a variety of platforms supported by Dialogflow, use dialogflow-fulfillment.
