Question

我有一个带有3个意图的dialogflow助手应用程序。第一个意图要求用户提供谷歌的位置和名称详细信息。我正在使用webhook来实现这个意图。我能够提取用户信息的名称和位置，但在显示webhook的输出后，它将退出流程。但它应该将位置参数传递给下一个意图并保持流程。任何人都可以帮助我如何阻止助手退出？这是webhook代码

'use strict';

const functions = require('firebase-functions');
const DialogflowApp = require('actions-on-google').DialogflowApp;

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {

    const requestPermission = (app) => {
      app.askForPermissions('To report ', [app.SupportedPermissions.NAME, app.SupportedPermissions.DEVICE_PRECISE_LOCATION]);
    };

    const userInfo = (app) => {
        if (app.isPermissionGranted()) {
            const address = app.getDeviceLocation().coordinates;
            const name = app.getUserName().givenName;
            if (name) {            
                app.tell(`You are name ${name}`);
            }
            else {
                // Note: Currently, precise locaton only returns lat/lng coordinates on phones and lat/lng coordinates 
                // and a geocoded address on voice-activated speakers. 
                // Coarse location only works on voice-activated speakers.
                app.tell('Sorry, I could not figure out where you are.Plaese try again');
            }
        } else {
            app.tell('Sorry, I could not figure out where you are.Please try again');
        }
    };

    const app = new DialogflowApp({request, response});
    const actions = new Map();
    actions.set('request_permission', requestPermission);
    actions.set('user_info', userInfo);
    app.handleRequest(actions);

});

问题是您在代码中调用了app.tell()，这是向助理发送消息然后结束对话的信号。

如果您要发送消息然后打开麦克风供用户回复，则应使用app.ask()代替。它采用相同的参数 - 唯一的区别是它希望用户回复。

因此，您的代码部分可能类似于

        if (name) {            
            app.ask(`You are name ${name}. What would you like to do now?`);
        }

（您应确保该用户的提示是他们希望回复的提示。如果您回复，审核流程将拒绝您的操作，并且用户不应该回复您。）

成功完成后，Dialogflow助手应用程序退出
