从网页获取特定的href

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

async function getHrefFromWebpage(url, targetText) {
  try {
    // 发送HTTP请求，获取网页内容
    const response = await axios.get(url);
    const html = response.data;

    // 解析HTML内容
    const $ = cheerio.load(html);

    // 遍历DOM树，找到包含特定href的元素
    const elements = $('a').filter((index, element) => {
      return $(element).text() === targetText;
    });

    // 提取href
    const hrefs = elements.map((index, element) => {
      return $(element).attr('href');
    }).get();

    return hrefs;
  } catch (error) {
    console.error('Error:', error);
    return [];
  }
}

// 示例调用
const url = 'https://example.com';
const targetText = 'Example Link';
getHrefFromWebpage(url, targetText)
  .then(hrefs => {
    console.log('Found hrefs:', hrefs);
  })
  .catch(error => {
    console.error('Error:', error);
  });
