How to get backgroundImage url in cheerio
问题
我试图获取我的Anime-Planet帐户的横幅，用于我的爬虫系统。
我尝试了我所知道的一切，使用cheerio，但我无法获取profileBackground的background-image URL。
属性
我尝试了
async function Al() {const cheerio = require("cheerio");const url = "https://www.anime-planet.com/users/kyoyacchi";const {data} = await client.axios.get(url, {headers: {"User-Agent":"Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Mobile Safari/537.36",},});const $ = cheerio.load(data);return $(".pull-beta.pull-alpha.pullup.editableBanner").find(".wrapper").find("profileBackground");}Al();
这个只返回了头像路径。

Properties
I tried

我了解到这是$('div[id=profileBackground]')。

你可以使用以下代码来获取图像路径：
axios.get(url).then(({data: html}) => {const $ = cheerio.load(html);const path = $("#profileBackground").attr("style").match(/background-image: *url *\((.+?)\)/)[1];console.log(path); // => /images/users/backgrounds/3966485.jpg?t=1660418964});
使用#some-id来选择具有id属性的元素。在CSS中，裸单词是指标签名称，所以p是<p></p>的选择器。在文档中，id应该是唯一的，所以通常不需要指定父选择器。
上面的正则表达式从background-image: url后面的括号中提取内容。
英文:
You can retrieve the image path with:
axios.get(url).then(({data: html}) => {const $ = cheerio.load(html);const path = $("#profileBackground").attr("style").match(/background-image: *url *\((.+?)\)/)[1];console.log(path); // => /images/users/backgrounds/3966485.jpg?t=1660418964});
Use #some-id to select by the id attribute. In CSS, a bare word refers to a tag name, so p is the selector for <p></p>. Ids are supposed to be unique in the document, so you don't usually need to specify parent selectors.
The regex above extracts the contents from the parentheses after background-image: url.
