我的意图模式中有 3 个插槽(account、dollar_value、recipient_first)用于 Alexa 技能,我想保存任何插槽由演讲者在会话属性中提供.
I have 3 slots (account, dollar_value, recipient_first) within my intent schema for an Alexa skill and I want to save whatever slots are provided by the speaker in the session Attributes.
我使用以下方法设置会话属性:
I am using the following methods to set session attributes:
def create_dollar_value_attribute(dollar_value): return {"dollar_value": dollar_value} def create_account_attribute(account): return {"account": account} def create_recipient_first_attribute(recipient_first): return {"recipient_first": recipient_first}然而,正如您可能猜到的,如果我想在 sessionAttributes 中保存多个插槽作为数据,sessionAttributes 将被覆盖,如下所示:>
However, as you may guess, if I want to save more than one slot as data in sessionAttributes, the sessionAttributes is overwritten as in the following case:
session_attributes = {} if session.get('attributes', {}) and "recipient_first" not in session.get('attributes', {}): recipient_first = intent['slots']['recipient_first']['value'] session_attributes = create_recipient_first_attribute(recipient_first) if session.get('attributes', {}) and "dollar_value" not in session.get('attributes', {}): dollar_value = intent['slots']['dollar_value']['value'] session_attributes = create_dollar_value_attribute(dollar_value)来自我的 lambda 函数对语音输入的 JSON 响应,其中提供了两个插槽(dollar_value 和 recipient_first)如下(我的猜测是 第二个 if 语句中的 create_dollar_value_attribute 方法覆盖了第一个):
The JSON response from my lambda function for a speech input in which two slots (dollar_value and recipient_first) were provided is as follows (my guess is that the create_dollar_value_attribute method in the second if statement is overwriting the first):
{ "version": "1.0", "response": { "outputSpeech": { "type": "PlainText", "text": "Some text output" }, "card": { "content": "SessionSpeechlet - Some text output", "title": "SessionSpeechlet - Send Money", "type": "Simple" }, "reprompt": { "outputSpeech": { "type": "PlainText" } }, "shouldEndSession": false }, "sessionAttributes": { "dollar_value": "30" } }sessionAttributes 的正确响应应该是:
"sessionAttributes": { "dollar_value": "30", "recipient_first": "Some Name" },如何创建此回复?有没有更好的方法在 JSON 响应中为 sessionAttributes 添加值?
How do I create this response? Is there a better way to add values to sessionAttributes in the JSON response?
推荐答案在我看来,使用 Python 添加 sessionAttributes 的最简单方法似乎是使用字典.例如,如果您想在会话属性中存储一些插槽以备将来使用:
The easiest way to add sessionAttributes with Python in my opinion seems to be by using a dictionary. For example, if you want to store some of the slots for future in the session attributes:
session['attributes']['slotKey'] = intent['slots']['slotKey']['value']接下来,您可以将其传递给构建响应方法:
Next, you can just pass it on to the build response method:
buildResponse(session['attributes'], buildSpeechletResponse(title, output, reprompt, should_end_session))本例中的实现:
def buildSpeechletResponse(title, output, reprompt_text, should_end_session): return { 'outputSpeech': { 'type': 'PlainText', 'text': output }, 'card': { 'type': 'Simple', 'title': "SessionSpeechlet - " + title, 'content': "SessionSpeechlet - " + output }, 'reprompt': { 'outputSpeech': { 'type': 'PlainText', 'text': reprompt_text } }, 'shouldEndSession': should_end_session } def buildResponse(session_attributes, speechlet_response): return { 'version': '1.0', 'sessionAttributes': session_attributes, 'response': speechlet_response }这会以推荐的方式在 Lambda 响应 JSON 中创建 sessionAttributes.
This creates the sessionAttributes in the recommended way in the Lambda response JSON.
如果最后一个不存在,也只是添加一个新的 sessionAttribute 不会覆盖它.它只会创建一个新的键值对.
Also just adding a new sessionAttribute doesn't overwrite the last one if it doesn't exist. It will just create a new key-value pair.
请注意,这可能在服务模拟器中运行良好,但在实际 Amazon Echo 上测试时可能会返回关键属性错误.根据这个帖子,
Do note, that this may work well in the service simulator but may return a key attribute error when testing on an actual Amazon Echo. According to this post,
在 Service Simulator 上,会话以 Session:{ ... Attributes:{}, ... } 开始当会话在 Echo 上开始时,会话根本没有 Attributes 键.
On Service Simulator, sessions starts with Session:{ ... Attributes:{}, ... } When sessions start on the Echo, Session does not have an Attributes key at all.
我解决这个问题的方法是在创建新会话时在 lambda 处理程序中手动创建它:
The way I worked around this was to just manually create it in the lambda handler whenever a new session is created:
if event['session']['new']: event['session']['attributes'] = {} onSessionStarted( {'requestId': event['request']['requestId'] }, event['session']) if event['request']['type'] == 'IntentRequest': return onIntent(event['request'], event['session'])更多推荐
