soup.find('script',type='application/ld+json').text 返回空数据，为什么我无法提取文本。>>> soup = BeautifulSoup(page.text,'lxml')>>> soup.find('script',type='application/ld+json').text**''>>> soup.find('script',type='application/ld+json')<script type="application/ld+json">{"@context":"http://schema.org","@type":"Organization","name":"Hamilton Medical Group - Dunkeld","url":"https://www.healthdirect.gov.au/australian-health-services/23000130/hamilton-medical-group-dunkeld/services/dunkeld-3294-sterling","contactPoint":{"@type":"ContactPoint","telephone":"03 5572 2422","email":"","website":"http://www.hamiltonmedicalgroup.net.au","fax":"03 5571 1606"},"address":{"@type":"PostalAddress","streetAddress":"14 Sterling Street","addressLocality":"DUNKELD","addressRegion":"VIC","postalCode":"3294","addressCountry":"AU"}}</script>>>> json.loads(soup.find('script',type='application/ld+json'))Traceback (most recent call last):  File "<stdin>", line 1, in <module>NameError: name 'json' is not defined>>> import json>>> json.loads(soup.find('script',type='application/ld+json'))Traceback (most recent call last):  File "<stdin>", line 1, in <module>  File "C:\Users\*******\Python38\lib\json\__init__.py", line 341, in loads    raise TypeError(f'the JSON object must be str, bytes or bytearray, 'TypeError: the JSON object must be str, bytes or bytearray, not Tag

使用.string属性获取<script>数据：

import json

from bs4 import BeautifulSoup

html_text = '''<script type="application/ld+json">{"@context":"http://schema.org","@type":"Organization","name":"Hamilton Medical Group - Dunkeld","url":"https://www.healthdirect.gov.au/australian-health-services/23000130/hamilton-medical-group-dunkeld/services/dunkeld-3294-sterling","contactPoint":{"@type":"ContactPoint","telephone":"03 5572 2422","email":"","website":"http://www.hamiltonmedicalgroup.net.au","fax":"03 5571 1606"},"address":{"@type":"PostalAddress","streetAddress":"14 Sterling Street","addressLocality":"DUNKELD","addressRegion":"VIC","postalCode":"3294","addressCountry":"AU"}}</script>'''

soup = BeautifulSoup(html_text, 'html.parser')

parsed_data = json.loads(soup.find('script',type='application/ld+json').string)

# print parsed data to screen:

print(json.dumps(parsed_data, indent=4))
