Python flask-ask中的Amazon Alexa主动事件请求 [英] Amazon Alexa Proactive Events request in Python flask-ask

问题描述

我正在尝试向

I am trying to make a request to the Proactive Events API by using the requests module of Python.

但是，我总是收到范围无效的响应。
有人可以帮忙吗？我究竟做错了什么？我的代码如下：

However I always receive a response that the scope is invalid. Can anyone help? What am I doing wrong? My code looks like this:

@ask.launch
def launch():
    content_type = "application/x-www-form-urlencoded;charset=utf-8"
    client_id = "amzn1.application-oa2-client.6a48XXXXXXX408"
    client_secret = "592XXXXxxxxxxx6"
    scope = "alexa::proactive_events"
    grant_type = "client_credentials"

    data = {"grant_type": grant_type, "client_id": client_id, "client_secret": client_secret, "scope": scope}
    r = requests.post("https://api.amazon.com/auth/O2/token", data=data, headers={"content-type": content_type})

    speech = render_template("welcome")
    reprompt = render_template("welcome_reprompt")
    return question(speech).reprompt(reprompt)

这是我得到的答复：

{'error_description': 'The request has an invalid parameter : scope', 'error': 'invalid_scope'}

推荐答案

Sinc出现无效范围的原因之一是您的技能清单中没有包含事件，因此我在此处提供了一些步骤。我发现使用SMAPI更新技能清单非常麻烦，所以我改用Ask cli。

Since one of the reason you get the invalid scope is that you dont have the events included in your skill manifest I include some steps here. I found quite cumbersome to use the SMAPI to update the skill manifest so instead I used ask cli.

• 安装ask-cli：获取授权代码为您的亚马逊帐户。在我的情况下，后端不是AWS Lambda函数，而是外部Web服务器


• 以json格式获取技能清单：
  询问api get-skill -s amzn1.ask.skill.ZZZYYYZZ-阶段开发> skill.json



• 向清单中添加通知权限和事件元素：

• install ask-cli: get authorization code for your amazon acount. In my case the backend is not an AWS lambda function but an external web server
• get the skill manifest in json format: ask api get-skill -s "amzn1.ask.skill.ZZZYYYZZ" --stage development > skill.json

• Add the notifications permission and the events elements to the manifest:

{
name： alexa :: devices：all：notifications：write
}

和

事件：{
出版物：[
{
eventName： AMAZON.AAABBBCC
}
]，
endpoint：{
uri： https：// XXXYYYZZ：443 / whatevercontext
}
}

更新清单：
询问api更新-skill -s amzn1.ask.skill.ZZZYYYZZ –阶段开发-f skill.json

• 在alexa应用程序中为您的特定技能启用通知

现在您应该能够获取令牌，下一步就是将通知发送到设备

Now you should be able to get the token and next step is to send the notification to the device
