Question

我尝试在heroku上部署我的程序，但它不起作用。我仍然是初学者，所以这个问题似乎没有必要。我第一次使用this 框架，并尝试在Heroku上部署它。这是我的代码：

import logging
import os
from flask import Flask
from flask_assistant import Assistant, ask, tell, context_manager

app = Flask(__name__)
assist = Assistant(app)
logging.getLogger('flask_assistant').setLevel(logging.DEBUG)


@assist.action('greeting')
def greet_and_start():
    speech = "Hey! Are you male or female?"
    return ask(speech)


@assist.action("give-gender")
def ask_for_color(gender):
    if gender == 'male':
        gender_msg = 'Sup bro!'

    else:
        gender_msg = 'Haay gurl!'

    speech = gender_msg + ' What is your favorite color?'
    return ask(speech)


@assist.action('give-color', mapping={'color': 'sys.color'})
def repeat_color(color):
    speech = 'Ok, {} is an okay color I guess.'.format(color)
    return ask(speech)


if __name__ == '__main__':
    port = int(os.getenv('PORT', 5000))

    print("Starting app on port %d" % port)

app.run(debug=True, port=port, host='0.0.0.0')

这是我的日志：

有没有人能解决问题？我将非常感谢任何帮助！

您遇到的错误是KeyError: 'Test'

这会出现在对服务器的API.ai（Dialogflow）请求中。

"metadata": {
    "intentId": "5d2861b5-a039-494b-8adc-fd7fb623003c",
    "intentName": "Test",
    "webhookForSlotFillingUsed": "false",
    "webhookUsed": "true"
}

您的意图名称为Test，它似乎不是@assist.action个密钥之一。我正在查看Flask Assistant的Quick Start guide（之前从未使用过），看起来他们使用Intent名称（顶部的标签）作为唯一键。

您的欢迎意图（可能包含greeting行动似乎名为Test。为了使这项工作符合预期，我认为解决方案是将意图Test重命名为greeting以匹配并允许Flask Assistant识别要运行的正确函数。
