Rasa如何从用户那里获取一个值（槽）

Question

我希望 rasa 在用户要求预测零件号时回复他们。

根据我的阅读，我知道我需要使用一个插槽，但是我找不到一个清楚的例子来说明如何从用户那里获取零件号。

如果我能看到一个示例 nlu、故事和域，这将给我一个良好的开端

1. 要求用户提供部件号
2. 用户输入部件号
3. Rasa 以部件号进行响应。

这是我目前所拥有的。

Answer 1

域文件保持不变。试试下面的东西。

故事文件：

## give me a forecast path1
* get_supplier_forecast{"partnumber":null}
  - slot {"partnumber":null}
  - utter_get_part_number
## give me a forecast path2
* get_supplier_forecast{"partnumber":"J12345-001"}
  - slot {"partnumber":"J12345-001"}
  - utter_confirm_part_number

包括这个 NLU 文件：

## intent:get_supplier_forecast
#this is how to mention slots in nlu file
- ['J12345-001'](partnumber)

注意：在您的情况下，我不知道“partnumber”是什么。如果它们太多，您可能想使用“查找表”。

从上面的变化首先如果插槽为空utter_get_part_number 将触发，如果插槽填充了值utter_confirm_part_number 将触发

如果这不能满足您的需求或无法按预期工作，您可以尝试 rasa 交互式培训。只需在 CMD 上运行 rasa interactive 或尝试 rasa x 交互式对话。从这里你可以选择你对机器人的期望
