Question

我的代码全部是关于在Raspberry Pi 3和Alexa的帮助下控制直流电动机的。为此，我使用了ngrok和flask-ask作为端点。使用raspberrypi3控制直流电动机的代码已工作。

因此，我在Amazon开发人员站点中创建了一个Intent，并使用Alexa控制直流电动机。该代码被卡在“对Alexa的响应文本”上。我尝试了几种调试代码的方法。但是不能。

这是对Alexa的JSON输入请求。

"request": {

"type": "SessionEndedRequest",

"requestId": "amzn1.echo-api.request.9cf91a8c-c484-41fe-91a8- 

9d6b8eb002a1",

"timestamp": "2019-02-07T10:42:06Z",

"locale": "en-IN",

"reason": "ERROR",

"error": {

"type": "INVALID_RESPONSE",

"message": "An exception occurred while dispatching the request to the skill."

}

}

使用Alexa和Raspberry Pi 3进行直流电机控制的Python文件：

from flask import Flask, render_template
from flask_ask import Ask, statement, question
import RPi.GPIO as GPIO #use GPIO library
from time import sleep


#initializing GPIO
GPIO.setwarnings(False)
Motor1A = 24
Motor1B = 23
Motor1E = 25

GPIO.setmode(GPIO.BCM)              # GPIO Numbering
GPIO.setup(Motor1A,GPIO.OUT)  # All pins as Outputs
GPIO.setup(Motor1B,GPIO.OUT)
GPIO.setup(Motor1E,GPIO.OUT)

#initializing flask ask
app = Flask(__name__)
ask = Ask(app, '/')

@ask.launch
def launch():
welcome_text = render_template('welcome_text')
return question(welcome_text)

@ask.intent('AMAZON.FallbackIntent')
def fallback():
reprompt_text = render_template('command_reprompt')
return question(reprompt_text)

def loop():
# Going forwards

GPIO.output(Motor1A,GPIO.HIGH)
GPIO.output(Motor1B,GPIO.LOW)
GPIO.output(Motor1E,GPIO.HIGH)


@ask.intent('DemoFan')

def control(OnOff):

command = OnOff

if command is None:

    #no command was given
    reprompt_text = render_template('command_reprompt')
    return question(reprompt_text)

elif command == 'on':

    loop()
    print("working ")
   # sleep(5)

    **response_text = render_template('Fan_command', 
OnCommand=command)   

     return statement(response_text).simple_card('Fan_command', 
response_text)**

elif command == 'off':
# Stop
    print("halt")
    GPIO.output(Motor1E,GPIO.LOW)
    response_text = render_template('Fan_command', 
OnCommand=command)   
    return 
statement(response_text).simple_card('Fan_command',response_text)


if __name__ == '__main__':

app.run(debug=True)

GPIO.cleanup()

无法调试“ Alexa技能响应问题”“使用RFPberry Pi 3b和Alexa借助opf ngrok和flask-ask控制直流电动机”
