问题描述
我正在用Lex构建QnA Bot,在其中,对于某些问题,将使用lambda挂钩,然后根据所发布的问题吐出一个答案。 按照lambda挂钩指示,“ lambda处理程序必须返回修改后的事件对象。”从event.res(需要进行操作)中可以看到,没有对话动作。我尝试将其插入,但没有用。我看到那里有一个卡对象,我尝试对其进行操作,但这也不起作用。一些帮助,将不胜感激!
Where i plugged the lambda hook in
我无法让该卡显示在客户端中。以下是event.res:
{
type: 'PlainText',message: '[User Input: "best offer",Source: ElasticSearch] These are some of our most popular offers:',session: {
qnabot_qid: 'TelcoBot.005',qnabot_gotanswer: true,qnabotcontext: { prevIoUs: [Object],navigation: [Object] },appContext: { altMessages: {} }
},card: { send: false,title: '',text: '',url: '' },_userInfo: {

以下是运行lambda之后的event.res,它清楚地表明它正在工作...:
{

}
],"l": "arn:aws:lambda:eu-west-1:418746351551:function:qna-telco-bestoffer-lambda","args": [

]
}
]
},"plainMessage": "[User Input: \"best offer\","answerSource": "ELASTICSEARCH"
}
这是函数:
exports.handler = (event,context,callback) => {
event.res.message = "Revised message";
event.res.card = {
"send": true,"genericAttachments": [
{
"title":"card-title","subTitle":"card-sub-title","imageUrl":"https://en.wikipedia.org/wiki/Image#/media/File:Image_created_with_a_mobile_phone.png","attachmentLinkUrl":"https://en.wikipedia.org/wiki/Image#/media/File:Image_created_with_a_mobile_phone.png","buttons":[
{
"text":"button-text","value":"Value sent to server on button click"
}
]
},]
};
callback(null,event);
};
