node.js - 当我提取图像数据时，它没有从 duckduckgo api 显示

Question

我正在使用node.js、microsoft bot框架和duckduckgo api，我想根据我得到的asnwer文本和url的问题显示图像结果，但图像没有在我的机器人中显示。谢谢。我提供了下面的代码

if (session.userData.search === 'DuckDuckGo') {

        request = require('request');
        var url = "https://api.duckduckgo.com/?q=" + encodeURIComponent(messageText) + "&format=json&pretty=1";
        console.log("data:", messageText);
        request(url, function(err, response, body) {
            if (err) console.log(err);
            if (response.statusCode == 200) {
                body = JSON.parse(body)
                session.sendTyping();
                console.log(body);
                if (!_.isEmpty(body.AbstractText)) {
                    session.send(body.AbstractText);
                    session.send(body.Image);
                } else if (!_.isEmpty(body.RelatedTopics[0])) {
                    session.send(body.RelatedTopics[0].Icon.URL);
                    session.send(body.RelatedTopics[0].Text);
                      session.send(body.RelatedTopics[0].Icon);
                      console.log("data1111" , body.RelatedTopics[0].Icon);
                    console.log("tubag:", body.RelatedTopics[1].Text);
                   /* session.send("Related Results");*/
                  /*  builder.Prompts.send(body.RelatedTopics[1].Text)
                    builder.Prompts.text(session, body.RelatedTopics[2].Text)
                    builder.Prompts.text(session, body.RelatedTopics[3].Text)*/

                } else {
                    session.send('https://duckduckgo.com/?q=%s', encodeURIComponent(messageText));
                }

            } else if (response.statusCode == 500) {
                session.send("error: server error");

            } else {
                session.send("error: problem with request code: " + response.statusCode)

            }
        });

图像/图标的 URL 可能为空。如果没有提供图像 URL，则在此示例中机器人将不会制作或发送任何图像附件。

request = require('request');
var url = "https://api.duckduckgo.com/?q=" + encodeURIComponent(messageText) + "&format=json&pretty=1";
console.log("data:", messageText);
request(url, function(err, response, body) {
    if (err) console.log(err);
    if (response.statusCode == 200) {
        body = JSON.parse(body)
        session.sendTyping();
        console.log(body);
        if (!_.isEmpty(body.AbstractText)) {
            session.send(body.AbstractText);
            session.send(body.Image);
        } else if (!_.isEmpty(body.RelatedTopics[0])) {
            session.send(body.RelatedTopics[0].Icon.URL);
            session.send(body.RelatedTopics[0].Text);
              session.send(body.RelatedTopics[0].Icon);
              console.log("data1111" , body.RelatedTopics[0].Icon);
            console.log("tubag:", body.RelatedTopics[1].Text);
           /* session.send("Related Results");*/
          /*  builder.Prompts.send(body.RelatedTopics[1].Text)
            builder.Prompts.text(session, body.RelatedTopics[2].Text)
            builder.Prompts.text(session, body.RelatedTopics[3].Text)*/

        } else {
            session.send('https://duckduckgo.com/?q=%s', encodeURIComponent(messageText));
        }

    } else if (response.statusCode == 500) {
        session.send("error: server error");

    } else {
        session.send("error: problem with request code: " + response.statusCode)

    }
