Question

我正在尝试使用 ibm 云功能将 webhook 连接到 nhs 网站，然后将结果输出到我的 watson 助手聊天机器人

function main(params) {
    const options = {
        uri: "https://api.nhs.uk/conditions/coronavirus-covid-19/"+encodeURIComponent(params.query_topic)+"/?url=https://api.eu-gb.assistant.watson.cloud.ibm.com/instances/...",
        json: true
    }
    return rp(options)
    .then(res => {
        return {text : res} 
    }) 
   }

webhook 成功并传递参数以从正确的页面返回信息

我希望结果只显示正文而不是所有标签，所以从“冠状病毒 (COVID-19) 的主要症状是：...”开始

这是完整的输出（无法添加图像）

我已经阅读了 IBM Watson 文档、NHS API 文档并浏览了 Stack Overflow，但找不到任何可以帮助我的内容。

Answer 1

您现在如何显示响应？只是 $webhook_response_1？

如果是这样，那么我认为 this documentation 会有所帮助。

大约一半的位置有一个包含两列的表格：条件和响应。 See Screenshot

它说，如果你让你的条件 $webhook_response_1 那么你的回应将是这样的：你的西班牙语单词：.

显然，将静态文本更改为您要查找的内容并更改属性以匹配您自己的 JSON 返回的内容。

编辑：

根据您的评论，您尝试使用以下内容显示数据：$webhook_result_1.text.mainEntityOfPage[9].text

但是，根据您的 json 格式，您实际上需要使用 $webhook_result_1.mainEntityOfPage[0].mainEntityOfPage[0].text

Answer 2

如上面的帖子所述，目前您向 nhs 网站执行请求，接收作为 json 负载的响应，然后将完整响应返回给 Watson Assistant Web 挂钩。如果您只需要返回的有效负载的子元素，则需要通过云函数提取该元素并返回此子元素。或者，您可以在 Watson Assistant 中仅在对话框中“显示”子元素，即如果您将响应返回给变量 $webhook_result_1，则如上所示，您仅在节点 $webhook_result_1.description 中使用（json 元素不清楚从上面，所以你可能需要调整才能正确）。在您的云函数中操作返回的 json 会更容易，然后在助手中操作。
