python bs4从按钮类内部的属性提取

因此，我尝试使用BeautifulSoup4获取属性的值

replay_url_data = matchdatatr[1].findAll("button",{"class":"replay_button_super"})

这就是我将所有数据放入对象的方式。 在控制台中键入replay\u url\u数据将返回：

<button class="replay_button_super" data-client-version="0.0.2.21" data-rel="spectatePopup" data-spectate-encryptionkey="bPPxpLIDmi0hRfU2U8B9Li1VJfTTx6pZ" data-spectate-endpoint="replays.cosmicradiance.com:80" data-spectate-gameid="4339075348" data-spectate-link="/api/spectate/UEJPNkN4MkIwUkZERUJ0MWUyZ3dDTmxGT25kanlUN2V6YnpuZUQ0bVlyMWRReGNDRXprZ1lQVnRnSkNHMG04Y2hUdVhxQm9abHFsQ2VBaTRaYVFPdnc9PQ==" data-spectate-platform="Modigu1" data-width="640"><i class="fa fa-play"></i>Replay</button>

这将返回[]空

replay_url_data[0].find('data-spectate-platform')

这将返回相同的空结果

replay_url_data[0].find('button',attrs={'class' : 'data-spectate-link'})

这个返回与上面相同的[]空

replay_url_data[0].find('data-spectate-platform')

在谷歌上搜索了3个小时后，到目前为止，没有任何东西能帮到我，我变得绝望了。我还是python和html新手，请原谅我的愚蠢。

要获取属性，请使用。attrs[data spectate link]或直接[data spectate link]

这就是你想要的

按钮设置汤内的标签。然后使用['data-spectate-link']可以在标记内设置属性

data spectate link是一个属性。要获取data spectate link的值，需要使用元素['data-spectate-link']

您可以使用findAll或CSS选择器select

或Css选择器

replay_url_data =soup.select("button.replay_button_super[data-spectate-link]")
print(replay_url_data[0]['data-spectate-link'])
