如何在用户输入输入时使Watson Conversation Api调用Web应用程序URL？ [英] How to make Watson Conversation Api Invoke a web Application Url when User Enters an Input?

问题描述

我有一个spring mvc应用程序，我想让我的用户调用一个bot，而基于用户输入的bot应该访问一个url并根据响应提供一个答案。我怎么能用Java实现这个？

I have a spring mvc application and I would like to make my user call a bot and the bot based on user input should access a url and based on the response provide an answer.How could I achieve this in Java?

推荐答案

没有直接的方法可以做到这一点。但是，Watson Conversation确实提供了处理此类请求的机制。
您需要告诉调用Java应用程序需要调用url。

There is no direct way to do it. However, Watson Conversation does provide a mechanism to handle such requests. You will need to tell the calling Java app that a url needs to be invoked.

这是通过使用两个功能完成的：
Context。请求
skip_user_input

This is done by using two features: Context.request skip_user_input

请求是一个具有args，name和result的特殊上下文变量。
它用于告诉调用应用程序它应该根据此变量执行某些操作。

A request is a special context variable that has args, name and result. It is used to tell the calling app that it should do some action based on this variable.

设置 skip_user_input 是可选的。在许多情况下，您可能希望在应用程序中执行某些业务逻辑，然后通过 result 提供其结果。将 skip_user_input 设置为true，将告诉Watson Conversation不等待来自用户的输入。因此，您在下一个节点上的条件应该基于结果中的内容。

Setting skip_user_input is optional. In many cases, you might want to execute some business logic in your application and then provide its results via result. Setting skip_user_input to true, will tell Watson Conversation to not wait for input from the user. Thus, your condition on the next node should be based on the content inside result.

{
  "output": {},
  "context": {
    "request": {
      "args": {
        "url_to_invoke": "your_url"
      },
      "name": "Call_A_URL",
      "result": "context.response"
    },
    "skip_user_input": true
  }
}
