如何在Watson对话中提取当前日期

问题描述

我需要在Watson对话对话框模型中创建一个条件，如下所示:

I need to create a condition, in Watson Conversation dialog model, like this:

如果今天是日期"< 2017年4月15日做某事.别的事.

if "today's date" < 04-15-2017 do something.else do something else.

我宁愿不询问用户当前日期并保存它.

I prefer not asking the user for current date and save it.

我尝试了很多方法，但是它们不起作用，我还尝试输出日期(不起作用):

I tried many ways but they don't work, I also tried to output the date (doesn't work):

{
  "context": {
    "currdate": "@sys-date:today"
  },
  "output": {
    "text": {
      "values": [
        "here it is $currdate"
      ],
      "selection_policy": "sequential"
    }
  }
} 

推荐答案

我不确定，但是在尝试过的所有测试中，如果用户今天不输入内容或其他内容，Watson不会识别，但是，我相信使用代码，我们可以做一些事情.可能与IBM Watson合作的人会正确回答您.

I'm not sure about that, but with all tests I've tried, if user dont type today or something, Watson dont recognize, but, I believe with code we can do something. Probably someone work with IBM Watson will answer you correctly.

但是，据我的基本知识:

But, in my basic knowledge:

尝试在条件中使用now()并将日期保存在上下文变量中.

Try use now() in condition and save the date inside context variable.

返回值为:

yyyy-MM-dd HH:mm:ss

使用您的代码获取上下文变量并仅获取日期...在可以设置条件之后...

Use your code to get the context variable and get just the date... after you can make conditions...

JSON示例:

{
  "context": {
    "dateHour": "<? now() ?>"
  },
  "output": {
    "text": {
      "values": [
        "Now is $dateHour."
      ],
      "selection_policy": "sequential"
    }
  }
}

我正在研究有关Watson中有关System实体的所有文档，并且如果用户不请求，我看不到任何有关提取数据的信息，但是，我怎么说，可能是IBM的工作人员会回答，我只是在尝试帮助您我的基本知识.

I'm study all documentation about System entities within Watson and I dont see anything about extract the data if user dont request, but, how I say, probably someone work at IBM will answer, I'm just trying help you with my basic knowledge.

有关此实体的文档，请参见@sys-date now() 此处.
