获取近5年的法定节假日和休息日，使用百度公共API

holiday.py

import datetime
import aiohttp
import asyncio
import tqdm

type_name = ['工作日', '休息日', '节假日']
max_conn = asyncio.Semaphore(15) # 最大并发连接数， 默认15

async def fetch(url, day):
    await max_conn.acquire()
    async with aiohttp.ClientSession(headers={'apikey': '这里替换成你的百度apikey'}) as session:
        async with session.get(url) as response:
            i = int(await response.text())
            max_conn.release()
            if i > 0:
                return '{},{}\n'.format(day.strftime('%Y-%m-%d'), type_name[i])

async def main():
    begin = datetime.datetime.strptime('20100101', '%Y%m%d') # 起始日期
    end = datetime.datetime.strptime('20161231', '%Y%m%d')   # 结束日期
    tasks = []
    while begin <= end:
        url = 'http://apis.baidu.com/xiaogg/holiday/holiday?d={}'.format(begin.strftime('%Y%m%d'))
        tasks.append(asyncio.ensure_future(fetch(url, begin)))
        begin += datetime.timedelta(days=1)
    responses = []
    for f in tqdm.tqdm(asyncio.as_completed(tasks), total=len(tasks)):
        r = await f
        if r:
            responses.append(r)
    return sorted(responses)


rst = asyncio.get_event_loop().run_until_complete(main())

with open('holiday.csv', 'w', encoding='utf8') as csvfile:
    csvfile.writelines(rst)

print('\ndone!')

python3.5测试通过。
