硒vs.纽约大都会Op

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。。。你知道吗

我正在努力抓取javascript生成的页面，尤其是那些大都会歌剧院的时间表。对于任何给定的月份，我都希望创建一个日历，其中只包含产品的名称，以及演出的日期和时间。我向它扔了美丽之声和硒元素，我可以得到很多关于作曲家爱情生活的信息，等等-但不是这三个元素。任何帮助都将不胜感激。你知道吗

在网站上（将来）应该寻找的一件事是对API的调用。我打开chromedev工具（F12）并在Network选项卡中重新加载页面。你知道吗

我发现了两个api调用，一个用于“productions”，一个用于“events”。“事件”响应包含更多信息。下面的代码调用“events”端点，然后返回该数据的子集（具体地说，根据您的描述，标题、日期和时间）。你知道吗

我不知道你想用这些数据做什么，所以我把它打印出来了。让我知道，如果代码需要更新/修改，我会尽我最大的努力来帮助！你知道吗

我使用python3.6.4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))

作为参考，here is a link to the full JSON response from the events endpoint.您可能需要一些更有趣的信息，但我只是抓住了您在描述中要求的信息的子集。你知道吗
