如何从Python中的<input type =“ hidden”获取值

Question

大家好，如标题中所概述，我想从输入type =“ hidden”获取值，但它返回'None'。是否存在获取它的方法？ 提前致谢！ 我期望从“ PaReq”和“ MD”中获取值

<input type="hidden" name="PaReq" value="eNpVUstuwjAQ/JWID4gfOA+jxRJtKpVKpAjooUfXOJCKJOAkJfx97RCgtXzYmd0dr2YNm73ROllr1RotYKHrWu60l2+nowmLWRBRHhJG4yAidCRgOVvpk4Afbeq8KgXxsU8B3aBtN2ovy0aAVKeneSoCGgZhBGiAUGgzTwYWY0oDjiMM6EpDKQst1gdZeG+yANRDUFVbNuYixrEtvAFozUHsm+ZYTxA6n89+bbu+ZeGryja6JKDHMMvWRbUV6/KtSJMdTjfq8r757NJkzmzcLXYzd6aAXAVsZaMFxYQTggOPjCfM3hhQz4Ms3BTi5WPlcexjO9bAwNE9NLsCjl3mLwPWY6NLdRE8smJ3BLo7VqW2FdbLewzoMfbzq3NUNdakLxKTmI2zSEYqzDgPGY/DQGZZKDPnc1/kFHNrE2U46iUdAORk0LBCNKzaRv++wC/NTqrF">

这是我的代码：

script = s.get('https://www.slamjam.com/on/demandware.store/Sites-slamjam-Site/en_IT/Adyen-Adyen3D',headers=headers)
bs_3d = BeautifulSoup(script_3d.text,"html.parser")
hidden_tags = bs_3d.find_all("input", type="hidden")
for tag in hidden_tags:
       print(tag.value)

Answer 1

您应该使用tag["value"]而不是tag.value。 来自documentation

  

属性

     

标签可以具有任意数量的属性。标签<b id="boldest">具有属性“ id”，其值是“ boldest”。您可以通过将标签视为字典来访问标签的属性：

>>>tag['id']
u'boldest'
