请问如何用正则表达式获取网页中内嵌的JavaScript中的字符串？

var BASE_DATA = {

    headerInfo: {

      id: 0,

      isPgc: false,

      userName: '',

      avatarUrl: '',

      isHomePage: false,

      chineseTag: '视频',

      crumbTag: 'video',

      hasBar: true

    },

    playerInfo: {

      videoId: 'v03004450000bhns5g3jvcldgj685gr0'

    },

videoId

reg = r'videoId:(.+?),'

videore = re.compile(reg)

videolist = re.findall(videore,html)
