Question

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。

您应该在网站上寻找（将来）的一件事是调用API。我打开了Chrome开发工具（F12）并在网络标签页面重新加载了该页面。

我发现了两个api电话，一个用于＆＃34;制作＆＃34;和＃34;事件＆＃34;。＆＃34;事件＆＃34;响应有更多的信息。下面的代码调用＆＃34;事件＆＃34;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）。

我不确定你想要对这些数据做什么，所以我只是将它打印出来。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))
