javascript - 无法使用 Cheerio/node.js 抓取图像

Question

我的问题非常简单。我正在尝试控制台记录来自下面的亚马逊链接的图像的 URL。要么来自更精确的选择

所以我花了大部分时间尝试选择链接的 id/class，但似乎只能得到与 #imgTagWrapperId 一样接近的值，它会返回大量冗余信息。理论上，我应该能够使用正则表达式来抓取链接，从而缩小范围，但就我的一生而言，我似乎只能替换我返回的文本，而不能简单地抓取它。或者，我如上所述尝试获取 img src 本身，结果只是返回一个无意义的代码字符串。当我查看页面源代码时，相同的文本球会出现在那里，但当我直接检查元素时不会出现。

const request = require('request');
const cheerio = require('cheerio');

request(`http://amazon.com/dp/B079H6RLKQ`, (error,response,html) =>{
    if (!error && response.statusCode ==200) {
        const $ = cheerio.load(html);
        const productTitle = $("#productTitle").text().replace(/\s\s+/g, '');

        const prodImg = $(`#imgTagWrapperId`).html();

        console.log(productTitle);

        console.log(prodImg);
    } else {
        console.log(error);
    }
})

当前代码如实返回产品标题，但返回 prodImg 输出:

预先感谢您对此提供的任何帮助和指导。我已经用尽了所有其他常用来源，并准备好被称为白痴。

有人想要选择之前和之后的 html，我会帮忙，但最好只查看链接中的页面源代码并按 ctrl+f。文字墙如下。
