以同步方式调用 Facebook Messenger API

Question

我正在使用 Facebook Messenger API 创建一个非常基本的聊天机器人。我希望能够在单个气泡中发送一系列消息。但是，当我在同一个函数中多次调用 API 时。我不能确定哪条消息会先显示。我如何使用 async/await 功能来正确排序消息？

初始函数调用：

const getStartedProcess = async(formattedText,senderID) => {
  const firstMessage = await sendTextMessage(senderID,"First message");
  const secondMessage = await sendTextMessage(senderID,"Second message");
  const thirdMessage = await sendTextMessage(senderID,"Third message");
}

帮手：

const sendTextMessage = async(recipientId, messageText) => {
  //format message correctly

  const sent = await callSendAPI(messageData);
  return 0;
}

const callSendAPI = async(messageData) =>{
  request({
    uri: 'https://graph.facebook.com/v2.6/me/messages',
    qs: { access_token: PAGE_ACCESS_TOKEN },
    method: 'POST',
    json: messageData

  }, function (error, response, body) {
    //Proccess
    return 0;
  });
}

这个怎么样：

const sendTextMessage = (recipientId, messageText) => {
    return new Promise((resolve, reject) => {
        //format message correctly
        request({
            uri: 'https://graph.facebook.com/v2.6/me/messages',
            qs: {access_token: PAGE_ACCESS_TOKEN},
            method: 'POST',
            json: messageData
        }, (error, response, body) => {
            if (error) {
                reject(error);
            } else {
                resolve(response);
            }
        });
    })
}

const getStartedProcess = async(formattedText, senderID) => {
    try {
        const firstMessage = await sendTextMessage(senderID, 'First message');
        const secondMessage = await sendTextMessage(senderID, 'Second message');
        const thirdMessage = await sendTextMessage(senderID, 'Third message');
    } catch (error) {
        console.log(error);
    }
}
