首先，必须提前道歉 - 这里几乎是新手，这是我的第一个问题;请善待......
我正在努力刮掉javascript生成的页面;特别是那些大都会歌剧院的时间表。对于任何给定的月份，我想创建一个仅包含作品名称和演出日期和时间的日历。我把美丽的汤和硒扔在上面，我可以获得关于作曲家的爱情生活等方面的大量信息 - 但不是这3个元素。任何帮助将不胜感激。
你应该在网站上寻找（将来）的一件事就是调用API。我打开了Chrome开发工具（F12）并在网络选项卡中重新加载了页面。
我发现了两个api调用，一个用于“制作”，一个用于“事件”。 “事件”响应有更多信息。下面的代码调用“事件”端点，然后返回该数据的子集（具体来说，根据您的描述，标题，日期和时间）。
我不确定你想用这些数据做什么，所以我就把它打印出来了。如果代码需要更新/修改，请告诉我，我会尽力帮助您！
我使用Python 3.6.4编写了这段代码
from datetime import datetime
import requests
BASE_URL = 'http://www.metopera.org/api/v1/calendar'
EVENT = """\
Title: {title}
Date: {date}
Time: {time}
---------------\
"""
def get_events(*, month, year):
params = {
'month': month,
'year': year
}
r = requests.get('{}/events'.format(BASE_URL), params=params)
r.raise_for_status()
return r.json()
def get_name_date_time(*, events):
result = []
for event in events:
d = datetime.strptime(event['eventDateTime'], '%Y-%m-%dT%H:%M:%S')
result.append({
'title': event['title'],
'date': d.strftime('%A, %B %d, %Y'),
'time': d.strftime('%I:%M %p')
})
return result
if __name__ == '__main__':
events = get_events(month=11, year=2018)
names_dates_times = get_name_date_time(events=events)
for event in names_dates_times:
print(EVENT.format(**event))
安慰：

作为参考，here is a link to the full JSON response from the events endpoint.您可能需要更多可能有趣的信息，但我只是抓住了您在描述中要求的子集。
