Bot Framework V4-TypeError:无法对已被撤销的代理执行“获取"

问题描述

我正在尝试对一个数据库进行休息查询，该数据库为用户存储了知识文章，并根据用户搜索的内容返回结果数组.每当我尝试搜索时，我都会得到:

I am trying to make a rest query against a database that stores knowledge articles for users and returns an array of results based on what the user has searched for. Whenever I try to search I get:

我已尝试如图所示将其添加到异步中，但仍然出现相同的错误.知道我在做什么错吗?

I have tried adding it to async as shown but I still keep getting the same error. Any idea what I am doing wrong?

const Response = async (turnContext) => {
    if (turnContext.activity.value.choice === 'feedbackProvider') {
        try {
            const feedbackBody = turnContext.activity.value.feedbackBody;
            const feedbackEmail = turnContext.activity.value.feedbackEmail;
            storage.write(feedbackBody, feedbackEmail);
            await turnContext.sendActivity(`Feedback Sent`);
        } catch (err) {
            console.log('fetch failed', err);
        }
    } else if (turnContext.activity.value.choice === 'issueRaiser') {
        try {
            const bugTitle = turnContext.activity.value.issueTitle;
            const bugDesc = turnContext.activity.value.issueDescription;
            const bugEmail = turnContext.activity.value.issueEmail;
            const request = require('request');
            request({
                method: 'Post',
                uri: `<uri>issues?title=${ bugTitle }&description=${ bugDesc } ${ bugEmail }&labels=bug`,
                json: true,
                headers: {
                    'Private-Token': '<token>'
                }
            });
            turnContext.sendActivity(`Issue Raised`);
        } catch (err) {
            console.log('fetch failed', err);
        }
    } else if (turnContext.activity.value.choice === 'knowledgeBaseSearch') {
        try {
            const knowledgeBaseTopic = turnContext.activity.value.knowledgeBaseTopic;
            request({
                url: process.env.SN_KB_URL + knowledgeBaseTopic,
                json: true,
                auth: {
                    'username': process.env.Ticket_User,
                    'password': process.env.Ticket_Key
                }
            }, async (error, response, body) => {
                try {
                    var stuff = [];
                    for (var i = 0, len = body.result.length; i < len; i++) {
                        stuff.push(
                            CardFactory.heroCard(body.result[i].short_description, ['imageUrl1'], [`${ process.env.SN_KB_Resp_URl }${ body.result[i].number }`])

                        );
                    }
                    let messageWithCarouselOfCards = MessageFactory.carousel(stuff);
                    await turnContext.sendActivity(messageWithCarouselOfCards);
                } catch (err) {
                    console.log(error);
                }
            });
        } catch (err) {
            console.log('fetch failed', err);
        }
    }
};

从论坛上的帖子中得知，我正在使用不支持Promises的请求模块，我认为这是导致我出错的原因.我现在开始对我的请求使用Axios，如下所示；

From my post on the forum I was informed that I was using a request module that did not support Promises, which I believe was causing my error. I've now began to use Axios for my request which is shown below;

try {
    return await axios.get(process.env.SN_KB_URL + knowledgeBaseTopic, {
        headers: {
          auth: {
          username: process.env.Ticket_User,
          password: process.env.Ticket_Key
        }
      }
    })
  }

但是，现在当我运行请求时，出现401未经授权"错误，并且我不确定请求有什么问题.

However now when I run the request I get a 401 'Unauthorised' error and I'm not sure what is wrong with my request.

推荐答案

发生此问题是因为我使用的请求模块不支持Promise.将我的请求模块更改为确实支持承诺的模块(我通过使用本文)解决了该问题.

This issue happened because I was using a request module that did not support promises. Changing my request module for one that did support promises (which I found out about by using this article) resolved the issue.
