我正在尝试抓取"imageToken"从下面的页面源的脚本标签的值，下面的python代码将获得令牌大约75%的时间，但其他时间的脚本标签的数量必须改变，它选择了错误的标签。
是否有任何方法可以搜索所有的脚本标签，特别是包含"imageToken"的标签?
这是75%的时间运行的代码。
html_source = driver.page_source
soup = BeautifulSoup(html_source, 'html.parser')
scripts = soup.find_all('script')[20]
findtoken = scripts.string.split(',')[58]
token = findtoken.split(':')[2].strip('"')
print(token)
我也试过了，但是没有返回任何东西:
html_source = driver.page_source
soup = BeautifulSoup(html_source, 'html.parser')
scripts = soup.find_all('script')
for script in scripts:
if 'imageToken' in script:
print(script)
这是script标签的来源，页面上也有很多其他脚本，但这是唯一一个带有"imageToken"的脚本。
<script>
((data) => {
/* TASK: Fix this. Move away from F3.page */
window.F3 = window.F3 || {};
window.F3.page = window.F3.page || {};
Object.assign(window.F3.page, data);

要搜索包含特定文本的标记，可以使用:contains(<my text>)选择器。
在您的示例中查看script是否包含文本imageToken，请使用:
print(soup.select_one("script:contains('imageToken')"))
注意:要使用选择器，请使用select()方法而不是find_all()，或select_one()方法而不是find()。
你的第二个方法是正确的，但它缺少.string
for script in scripts:
if 'imageToken' in script.string: # <== add .string
print(script.string)
