order-update.js 发送“{}”作为交易 api actions-on-google 中的响应

order-update.js sent "{}" as response in transaction api actions-on-google

我正在尝试在用户发送订单后发送有关订单状态的更新。我一直在使用 actions on google transaction guide 代码来构建我的系统。但是,一开始我遇到了 "Cannot read property 'JWT' of undefined" 错误,并用 const {google} = require('googleapis');.

更改了我的代码

现在,当 运行 order-update.js 文件时,我在控制台上收到“{}”作为响应并且无法收到通知。 我正在移动设备上尝试。我不确定是不是因为我使用的是沙盒模式。

const {google} = require('googleapis');
const request = require('request');
const {OrderUpdate} = require('actions-on-google');
const key = require('<my_service_account_path>');
const jwtClient = new google.auth.JWT(
  key.client_email,
  null,
  key.private_key,
  ['https://www.googleapis.com/auth/actions.fulfillment.conversation'],
  null
);

jwtClient.authorize((err, tokens) => {
  if (err) {
    console.log(err);
    return;
  }
  const currentTime = new Date().toISOString();
  const actionOrderId = '<my_order_id>';
  const orderUpdate = new OrderUpdate({
    actionOrderId: actionOrderId,
    orderState: {
      label: 'Order has been delivered!',
      state: 'FULFILLED',
    },
    updateTime: currentTime,
  });


  const bearer = 'Bearer ' + tokens.access_token;
  const options = {
    method: 'POST',
    url: 'https://actions.googleapis.com/v2/conversations:send',
    headers: {
      'Authorization': bearer,
    },
    body: {
      custom_push_message: {
        order_update: orderUpdate,
      },
      // The line below should be removed for non-sandbox transactions.
      is_in_sandbox: true,
    },
    json: true,
  };


  request.post(options, (err, httpResponse, body) => {
    if (err) {
      console.log(err);
      return;
    }
    console.log(body);
  });
});

在指南中,我找不到我应该得到的任何响应,但我认为“{}”不是答案。 对于推送通知,“200:OK”是预期的响应。

您正在记录正文(或错误),它是一个 JSON 对象。对于成功的响应,一个空的 JSON 正文并不奇怪。错误应包含错误消息。

如果您想验证响应是 HTTP 代码 200,"OK",那么您应该检查 httpResponse.statusCode

documentation 状态

Some important order updates will result in a push notification being sent to the user's Assistant-enabled mobile devices.

但并不是说所有都会。目前尚不清楚它认为 "important" 是什么,但是,设置 userNotification 字段 "is a suggestion to notify and is not guaranteed to result in a notification." 您可以添加类似

的字段
  const orderUpdate = new OrderUpdate({
    actionOrderId: actionOrderId,
    orderState: {
      label: 'Order has been delivered!',
      state: 'FULFILLED',
    },
    updateTime: currentTime,
    userNotification: {
      title: "Update on your order",
      text: "Your order has been delivered!"
    }
  });
