使用 Alexa 从 Raspberry Pi 打开警报时如何使两个 Intent 工作

如何解决使用 Alexa 从 Raspberry Pi 打开警报时如何使两个 Intent 工作

我开发了一个 Alexa 技能，我可以控制 GPIO 引脚来打开 LED 灯，或者在我的情况下切换我的警报面板来布防系统。

这就是我所做的

（Alexa 开发者帐户）我创建了两个 Intent

报警意图
代码意图

然后是两种插槽类型

状态
代码

AlarmIntent 的示例语句是

alarm {status}
{status} alarm

CodeIntent 的示例语句是

{code} code
code {code}

然后将其添加到各自的插槽类型中。

对于第一部分，AlarmIntent 效果很好。当我说 Alexa 警报时，Alexa 会回应说“欢迎使用您的警报”，然后您可以通过说“警报开启”来回应，然后打开 LED 灯！太棒了！

对于第二部分 CodeIntent，这就是我陷入困境的地方。

我从 Alexa 开发者帐户（Json 编辑器选项卡）获得的代码

                        }
                    }
                ]
            },{

                    {

                                "1234"
                            ]
                        }
                    },{
                        "id": "codeoff","name": {
                            "value": "codeon","synonyms": [
                                "1234"
                            ]
                        }
                    }
                ]
            }
        ]
    }
}
}

然后在 RaspBerry Pi Python 文件上：

import logging
import os

from flask import Flask
from flask_ask import Ask,request,session,question,statement
import RPi.GPIO as GPIO

app = Flask(__name__)
ask = Ask(app,"/")
logging.getLogger('flask_ask').setLevel(logging.DEBUG)


STATUSON = ["alarm on","turn on"] # all values that are defined as synonyms in 
type
STATUSOFF = ["alarm off","turn off"]
CODEON = ["1234"]
CODEOFF = ["1234"]

@ask.launch
def launch():
speech_text = 'Welcome to your alarm.'
return question(speech_text).reprompt(speech_text).simple_card(speech_text)

@ask.intent('AlarmIntent',mapping = {'status':'status'})


@ask.launch
def launch():
speech_text = 'Please provide pin.'
return question(speech_text).reprompt(speech_text).simple_card(speech_text)

@ask.intent('CodeIntent',mapping = {'code':'code'})
def Gpio_Intent(code,status,room):
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.setup(17,GPIO.OUT)
if status in STATUSON:
    if code in CODEON:
        GPIO.output(17,GPIO.HIGH)
    return statement('Alarm Activated')
elif status in STATUSOFF:
    if code in CODEOFF:
        GPIO.output(17,GPIO.LOW)
    return statement('Alarm deactivated')
else:
    return statement('Sorry,this command is not possible.')

@ask.intent('AMAZON.HelpIntent')
def help():
speech_text = 'You can say hello to me!'
return question(speech_text).reprompt(speech_text).simple_card('HelloWorld',speech_text)


@ask.session_ended
def session_ended():
return "{}",200


if __name__ == '__main__':
if 'ASK_VERIFY_REQUESTS' in os.environ:
    verify = str(os.environ.get('ASK_VERIFY_REQUESTS','')).lower()
    if verify == 'false':
        app.config['ASK_VERIFY_REQUESTS'] = False
app.run(debug=True)

所以进入正题。当您说“Alexa 闹钟”时，您会收到欢迎回复，然后您可以说“闹钟开”，闹钟就会打开。但是在闹钟打开之前，Alexa 需要询问一个 PIN 码（在这种情况下，1234 一旦您回复“1234”，闹钟就需要打开。

我认为我出错的代码部分在这里：

@ask.intent('AlarmIntent',mapping = {'status':'status'}) --> Saying Alarm On

@ask.launch
def launch():
speech_text = 'Please provide pin.'
return question(speech_text).reprompt(speech_text).simple_card(speech_text) --> Alexa asks for Pin

@ask.intent('CodeIntent',mapping = {'code':'code'}) --> Saying "1234"

##and this is where the magic should happen :-) but its not :-( ##
def Gpio_Intent(code,this command is not possible.')

我得到的唯一回应是……没什么。 :-)

谢谢
