node.js - 如何使 Dialog Fulfillment Google Calendar 集成工作？

问题描述

我是 node.js 的新手，我正在尝试使用 Dialogflow 构建一个聊天机器人，让您计划约会并将约会插入 Google 日历。无论我尝试什么，我似乎总是遇到同样的错误（没有请求意图的处理程序）。有没有人看到可能出了什么问题或者已经尝试过本教程并且可以正常工作？

我尝试过的事情：

更新了 package.json 中的依赖项
更正了时区（我住在比利时/欧洲）和 timeZoneOffset
将结算帐号关联到 Google Cloud Platform 中的项目

这是我遵循的教程：

谷歌日历 Github

这是特定意图“安排约会”的屏幕截图。它会自动转到默认响应，但应该转到： Ok, let me see if we can fit you in. ${appointmentTimeString} is fine!. 此意图中有一个自定义实体：@AppointmentType 有 2 个选项：- 车辆登记 - 驾驶执照

在意图屏幕截图中，您还可以看到时间给出了今天的日期（在本例中为 2020-02-28），而它应该给出所请求的约会日期（在本例中为 2020-03-10）。这可能会导致错误，但我不知道如何在内联编辑器中修复它。

我来自内联编辑器的 index.js（日历 ID 和服务帐户数据是正确的，只是从这里取出）：

   }
 
   let intentMap = new Map();

       if (err || calendarResponse.data.items.length > 0) {

       } else {
         // Create event for the requested time period
         calendar.events.insert({ auth: serviceAccountAuth,
           calendarId: calendarId,
           resource: {summary: appointment_type +' Appointment', description: appointment_type,
             start: {dateTime: dateTimeStart},
             end: {dateTime: dateTimeEnd}}
         }, (err, event) => {

         }
         );
       }
     });
   });
 }
