Alexa Skill using flaskask:HTTP 500:内部服务器错误

Question

我只是在学用烧瓶问写Alexa的技巧。 这是烧瓶的代码_应用程序副本公司名称：

from flask import Flask, render_template
from flask_ask import Ask, statement, question, session
import random

app = Flask(__name__)

ask = Ask(app, "/")

def armstrong(num):

   order = len(str(num))

   num_sum = 0


   temp = num
   while temp > 0:
    digit = temp % 10
    num_sum += digit ** order
    temp //= 10


    if num == num_sum:
        return True
    else:
        return False

@ask.launch

def new_game():

  welcome_msg = render_template('welcome')

  return statement(welcome_msg)



@ask.intent("AnswerIntent", convert = {'first': int} )

def answer(first):

   if armstrong(int(first)):
    msg = render_template('win')
   else:
    msg = render_template('lose')

   return statement(msg)


if __name__ == '__main__':

app.run()

以下是intents JSON文件的代码：

^{pr2}$

以下是我的例句：

AnswerIntent {number}
AnswerIntent My number is {number} 
AnswerIntent Is {number} an armstrong number

但我的命令行错误是：

ngrok显示以下错误：

测试时输入“启动阿姆斯特朗”后的服务响应为：

    There was an error calling the remote endpoint, which returned HTTP 500 :
    INTERNAL SERVER ERROR

这是我的第一个Alexa技巧，我试图在Python上使用Flask和flaskask来实现它。 请帮忙。在

看起来这可能是Alexa测试工具的问题。请参见https://github.com/johnwheeler/flask-ask/issues/152和https://forums.developer.amazon.com/questions/78372/timestamp-is-sent-in-different-formats.html。在

我可以确认我的技能可以在Echo设备和Alexa管理页面测试部分的JSON选项卡上工作。但是失败了echosim.io公司在文本选项卡中。在
