Google Assistant API第2版用户的存储空间

Question

我正在尝试使用Dialogflow v2 API开发Google Action

我的函数将值保存到用户存储，如下所示

def save_value(value):
res = {
  "fulfillmentText": "Set value to {}".format(int(value)),
  "payload": {
    "google": {
      "userStorage": str(value)
    }
  }
}
print ("Saved value")
response = jsonify(res)
return response

我从Dialogflow中的测试中得到了以下回馈

{
  "fulfillmentText": "Set value to 36237269",
  "payload": {
    "google": {
      "userStorage": "36237269"
    }
  } 
}

在整个会话期间都可以使用，我可以通过

在以后的意图中使用它

 value = request_json['originalRequest']['data']['user']['userStorage']

但是，数据仅存储一个会话-如果我再次调用动作，则不会保存任何内容。

这是使用用户存储的正确方法吗？有没有人成功地在Python中使用它？

有效的“响应”

{
  "conversationToken": "[]",
  "finalResponse": {
    "richResponse": {
      "items": [
        {
          "simpleResponse": {
            "textToSpeech": "Text"
          }
        }

    }
  },
  "responseMetadata": {
    "status": {
      "message": "Success (200)"
