Question

{我怎么从书页上刮下来。我可以使用Facebook Graph API还是应该使用像Scrappy或{a4}的Scrappy这样的Python web抓取库？在

在Facebook上为组织的使命声明创建About页面的例子如下：

from bs4 import BeautifulSoup
import requests

response = requests.get("https://www.facebook.com/pg/officialstackoverflow/about/?ref=page_internal")
html = response.content
soup = BeautifulSoup(html, "html")
mission_statement = soup.find('div', attrs={'class': '_3-8w'})
print(mission_statement.text)
