隔离 bs4/beautifulSoup 中的属性

Question

我试图通过使用 beautiful soup (bs4) 来隔离列为属性的值。我已经列出了我的输出，但我不确定如何以字符串形式从 "value" 中获取字符串。

import requests
from bs4 import BeautifulSoup as bs

html = """
<div class="buttons">
    <form method="POST" action="/1/token/approve">
        <a class="button primary" href="/login?returnUrl=%2F1%2Fauthorize%3FrequestKey%3Df079a57f7157bf084676c5a9c3d0443e">Log in</a>
        <input type="submit" class="deny" value="Deny">

        <input type="hidden" name="requestKey" value="f079a57f7157bf084676c5a9c3d0443e">

        <!-- Need to pull this value -->
        <input type="hidden" name="signature" value="1500374930141/76d6e6bf4e95732eece754cc00315a242db0ffcf2758052c1fd64f2e6024611b">

    </form>
</div>
"""

#pull web page
f = requests.get(html)

# pass HTML to soup
soup = bs(f.text, "lxml")
bsIn = soup.find('input', attrs={'name':'signature'})

print (bsIn) # returns <input name="signature" type="hidden" value="1500387161323/9a240ffc8dfff875bc272f0defba27e58f4ffd8e7a29d00edc3528776bca3039"/>

你可以通过索引获取美汤中的HTML/XML个属性，如：

print(bsIn<b>['value']</b>)

这将因此打印字符串：

'1500387161323/9a240ffc8dfff875bc272f0defba27e58f4ffd8e7a29d00edc3528776bca3039'

它将被打印成：

1500387161323/9a240ffc8dfff875bc272f0defba27e58f4ffd8e7a29d00edc3528776bca3039
