Twilio错误-90100：无效的自动驾驶操作JSON

Question

我提到了Mwangi Kabiru发表的Twilio博客：

https://www.twilio.com/blog/serverless-whatsapp-chatbot-python-google-cloud-functions-twilio

可能的解决方案针对Actions模式测试您的JSON响应(https://carnelian-neanderthal-8008.twil.io/assets/actionsSchema.JSON)

如何下载在Google Cloud函数上创建的webhook的JSON文件，并根据Twilio Actions模式对其进行测试？有人能帮我解决这个问题吗？

谷歌云功能代码：

import gspread
from oauth2client.service_account import ServiceAccountCredentials
from datetime import datetime
import requests
from twilio.twiml.messaging_response import MessagingResponse


def whatsapp_webhook(request):
    '''

    }

        
    # use creds to create a client to interact with the Google Drive API
    scope = ['https://spreadsheets.google.com/feeds', 'https://www.googleapis.com/auth/drive']
  
    creds = ServiceAccountCredentials.from_json_keyfile_dict(data, scope)
  
    client = gspread.authorize(creds)
  
    # Find a workbook by name and open the first sheet
    # Make sure you use the right name here.

    wb = client.open("Covid_DB")
    sheet = wb.worksheet('Oxygen')
    
    #Checking whether Google Cloud is able to access Google Sheets

    row = ['Google Sheet Accessed successfully', ':)']
    index = 9
    sheet.insert_row(row, index)

    #Sending the required info to the user

    twilio_response = MessagingResponse()
    msg = twilio_response.message()
    msg.body('1) ' + ', '.join(sheet.row_values(2)) + ' 2) ' + ', '.join(sheet.row_values(3)))

    return str(twilio_response)

当通过redirect从Twilio Autopilot调用URL时，需要为Twilio Autopilot返回JSON，而不是Twiml。

您需要更改构建返回消息的部分：

twilio_response = MessagingResponse()
msg = twilio_response.message()
msg.body('1) ' + ', '.join(sheet.row_values(2)) + ' 2) ' + ', '.join(sheet.row_values(3)))
return str(twilio_response)

在此处返回JSON：

from flask import jsonify
body = {
    'actions': [
        {
            'say': '1) ' + ', '.join(sheet.row_values(2)) + ' 2) ' + ', '.join(sheet.row_values(3))
        },
        {
            'listen': True
        }
    ]
}
return jsonify(body)
