輸出 'https://china-testing.github.io/' 的返回頭
- 參考答案
In [1]: import requests
In [2]: url = 'https://china-testing.github.io/'
In [3]: response = requests.get(url)
In [4]: response.request.headers
Out[4]: {'User-Agent': 'python-requests/2.18.4', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive'}
requests是HTTP訪問極其重要的庫,比較常用的屬性有:response.status_code、response.text。

from bs4 import BeautifulSoup
def get_upcoming_events(url):
req = requests.get(url)
soup = BeautifulSoup(req.text, 'lxml')
events = soup.findAll('article')
for event in events:
event_details = {}
event_details['name'] = event.find('h1').find("a").text
print(event_details)
get_upcoming_events('https://china-testing.github.io/')

BeautifulSoup的默認解析器爲html.parser,處理大頁面比較吃力,爲此使用lxml。解釋器html5lib的行爲和瀏覽器表現類似。
