Alexa Flask 询问是/否响应处理 [英] Alexa Flask Ask Yes / No response handling

问题描述

我正在尝试使用 Python 中的 Flask Ask 创建一个简单的 Alexa 技能.

I am trying to create a simple Alexa skill using Flask Ask in python.

我有一个名为SearchIntent"的意图，带有一个searchterm"槽，python代码如下所示:

I have an intent called "SearchIntent" with a "searchterm" slot and the python code looks something like this:

@ask.intent("SearchIntent")
def SearchIntent(searchterm):
    resList = []
    searchterm = searchterm.lower()

    for item in somelist:
        if item.find(searchterm) != -1:
            resList.append(item)


    return question("I Found " + str(len(resList)) + ", Do you want me to list them all?")

我想检查用户的响应，如果他说是"而不是阅读所有结果:

I want to check if the response from the user, if he says "Yes" than read all the results:

return statement('
'.join(resList))

如果用户说不，则执行一些其他操作

and if the user says no, to perform some other action

类似:

...

    return question("I Found " + str(len(resList)) + ", Do you want me to list them all?")

if "return question" == "yes":
   do something
else:
   do something else

我不想在 YesIntent 中再次创建搜索函数，是否可以在同一个函数中执行类似的操作?

I don't want to create the search function again in a YesIntent, Is it possible to do something like this within the same function?

先谢谢你！

推荐答案

这在使用flask ask 的建议方式中是不可能的.调用 return 后，您将离开 SearchIntent() 函数，无法检查答案或运行其他代码.
但是，您仍然可以使其工作:在用户回答您的问题后发送一个新的意图，并且flask-ask 调用相应的函数.通过使用会话属性，正如@user3872094 所建议的，您可以在这个新函数中处理您的 searchterm.会话属性用于在不同意图请求之间的会话期间保留用户输入.
检查这个最小的例子:

This is not possible in the suggested way using flask ask. After you call return, you leave your SearchIntent() function and have no way to check the answer or run additional code.
However, you can still make it work: after the user answers your question a new intent is sent and flask-ask calls the according function. By using session attributes, as suggested by @user3872094, you can process your searchterm in this new function. Session attributes are used to preserve user input during a session between different intent requests.
Check this minimal example:

@ask.intent("SearchIntent")
def SearchIntent(searchterm):
    session.attributes['term'] = searchterm
    return question("I understood {}. Is that correct?".format(searchterm))

@ask.intent('AMAZON.YesIntent')
def yes_intent():
    term = session.attributes['term'] 
    return statement("Ok. So your word really was {}.".format(term))

@ask.intent('AMAZON.NoIntent')
def no_intent():    
    return statement("I am sorry I got it wrong.")

将 Amazon Yes 和 No 意图添加到您的 intent_schema:

Add the Amazon Yes and No intents to your intent_schema:

{
    "intents": [
        {
        "intent": "SearchIntent",
        "slots": [{
            "name": "searchterm",
            "type": "AMAZON.LITERAL"
        }]
        },{
            "intent": "AMAZON.NoIntent"
        }, {
            "intent": "AMAZON.YesIntent"
        }      
    ]
}
