Python 使用bs4从javascript函数中提取src

如何使用bs4从下面的代码中提取src

脚本在我使用request时显示，但我无法从中获取src

我尝试了page.get（“src”）

但它不起作用

<script>
    function hls() {
        document.getElementById("videowrapper_hls").innerHTML = '<iframe src="/redirect/dHlFVXhUNU1wTHB5T2ZnblorQ1k4aVVyV1JKRjRkUEpnaExzeVpUUHZDWmJkMGF2N0pPa3RPdDRQYjFHYmhRWnljclVXa0l0V0hLK3VuSElFTUExNVE9PQ==" scrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>'

        if ($('#videowrapper_video').length > 0) {
          document.getElementById("videowrapper_video").innerHTML = ''
        }

        if ($('#videowrapper_fembed').length > 0) {
          document.getElementById("videowrapper_fembed").innerHTML = ''
        }

        if ($('#videowrapper_gounlimited').length > 0) {
          document.getElementById("videowrapper_gounlimited").innerHTML = ''
        }

        if ($('#videowrapper_mixdrop').length > 0) {
          document.getElementById("videowrapper_mixdrop").innerHTML = ''
        }

    }
</script>

函数hls（）{
document.getElementById（“videowrapper_hls”）.innerHTML=''
如果（$（'#videowrapper_video'）。长度>0）{
document.getElementById（“videowrapper_video”）.innerHTML=''
}
如果（$（'#videowrapper_fembed'）。长度>0）{
document.getElementById（“videowrapper_fembed”）.innerHTML=“”
}
如果（$（'#videowrapper_gounlimited'）。长度>0）{
document.getElementById（“videowrapper\u gounlimited”）.innerHTML=“”
}
如果（$（'#videowrapper_mixdrop'）。长度>0）{
document.getElementById（“videowrapper\u mixdrop”）.innerHTML=''
}
}

我建议使用正则表达式，如下所示：

html = '''<script>
    function hls() {
        document.getElementById("videowrapper_hls").innerHTML = '<iframe src="/redirect/dHlFVXhUNU1wTHB5T2ZnblorQ1k4aVVyV1JKRjRkUEpnaExzeVpUUHZDWmJkMGF2N0pPa3RPdDRQYjFHYmhRWnljclVXa0l0V0hLK3VuSElFTUExNVE9PQ==" scrolling="no" frameborder="0" width="700" height="430" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true"></iframe>'

        if ($('#videowrapper_video').length > 0) {
          document.getElementById("videowrapper_video").innerHTML = ''
        }

        if ($('#videowrapper_fembed').length > 0) {
          document.getElementById("videowrapper_fembed").innerHTML = ''
        }

        if ($('#videowrapper_gounlimited').length > 0) {
          document.getElementById("videowrapper_gounlimited").innerHTML = ''
        }

        if ($('#videowrapper_mixdrop').length > 0) {
          document.getElementById("videowrapper_mixdrop").innerHTML = ''
        }

    }
</script>'''

import re
match = re.search(r'<iframe src=\"(.*?)\"', html)
src = match.group(1) if match is not None else ''   
print(src)
