从节点js中的html响应中获取值
非常新的 nodejs 没有找到类似的帖子。我正在尝试data-clp-course-id从下面的代码中获取 html 响应，
const https = require('https')
const options = {
hostname: 'www.udemy.com',
path: '/course/az-303-microsoft-azure-architect-practice-test-2020/',
method: 'GET'
}
const req = https.request(options, res => {
console.log(`statusCode: ${res.statusCode}`)
res.on('data', d => {
// process.stdout.write(d)
})
})
req.on('error', error => {
console.error(error)
})
req.end()
示例 html 响应（仅给出响应的一部分）：
<!DOCTYPE html>
<html>
<head>
<meta name="medium" content="mult">
<meta name="title" content="AZ-303: Microsoft Azure Architect Practice Test 2020">
<meta property="fb:app_id" content="313137469260">

对如何data-clp-course-id从 html 响应中获取值有帮助吗？

只是使用迈克的建议async function getCourseCode() { try { let response = await fetch('https://www.udemy.com/course/az-303-microsoft-azure-architect-practice-test-2020/'); let body = await response.text(); console.log(response.status); //console.log(body); let responseBody = body.match(/data-clp-course-id="(\d+)"/) let courseID = responseBody[1]; console.log(courseID); } catch(exception){ console.log(exception); }}getCourseCode();
