Javascript 我开始使用urlq=使用Cheerio

我想用啦啦队来刮胡子.但是我有一个小问题.我在客户端得到的所有href值都以"/url？q=".例如，像这样:

'/url?q=https://www.nimh.nih.gov/health/topics/auti… pkCZkQFnoECAYQAg&usg=AOvVaw1E4L1bLVm9OdBSFMkjJftQ'

Google搜索的元素是:

<a jsname="UWckNb" href="https://www.nimh.nih.gov/health/topics/autism-spectrum-disorders-asd"...

它不包含"/url?q="个."/url?q="从何而来？

app.get('/scrape', (req, res) => {
    request('https://www.google.com/search?q=asd', (error, response, html) => {
        if (response.statusCode == 200) {
            
            const $ = cheerio.load(html);
            const results = [];
            const links = $('a'); 
            links.each((index, link) => {
                const href = $(link).prop('href'); 
                const h3 = $(link).find('h3'); 
                
                if (h3.length > 0) {
                    const textContent = h3.text().trim();
                    results.push({ href, textContent }); 
                }
            });
        
            const responseData = {
                links: results,
                total: results.length
            };

            res.json(responseData); 
        } else {
            console.error('Unexpected status code:', response.statusCode);
            res.status(500).send('Unexpected status code.'); 
        }
    });
});

我知道我可以这样解决它:

 const actualUrl = decodeURIComponent(href.split('/url?q=')[1].split('&')[0]);

但我想知道这"/url?q="在哪里，我做错了什么？
