前言：
最近一直在看python方面的知识，突然对python对视频如何处理非常感兴趣，于是百度一下，看看网上的方法，根据兴趣，试着从网上下载一个m3u8的实例看看。
本实例为个人学习使用，试着用了线程的方法。
一、由于时间紧，没有直接从网页中获取m3u8网址，而是把m3u8地址放到excel表格中。
二、从表格中读取m3u8地址，从而获取视频真实地址进行下载。
一、多任务异步处理
# coding:utf-8import requestsimport refrom aiohttp import ClientTimeout, ClientErrorfrom openpyxl import load_workbookimport asyncioimport aiohttpheaders = { "User-Agent": "Mozilla/5.0(Windows NT 6.1;WOW64) AppleWebKit/537.36(KABUL, like Gecko) " "Chrome/86.0.4240.198Safari/537.36 " }async def get_page(url, title): print("正在下载", url) timeout = ClientTimeout(total=5000) async with aiohttp.ClientSession(timeout=timeout) as session: try: async with await session.get(url, headers=headers) as response: page_content = await response.read() with open(f"{title}.mp4", "ab+") as f: f.write(page_content) except ClientError as e: print(e)wk = load_workbook(r"E:\project\project03\m3u8 - 副本 (2) - 副本.xlsx")sheet = wk.activenames = []urls = []for i, j in zip(sheet["A"], sheet["B"]): names.append(i.value) urls.append(j.value)wk.close()for i, j in zip(names, urls): resp = requests.get(j, headers=headers) data = resp.text # print(data) indexs_list = re.findall(r'https(.*?).ts', data) stasks = [] for k in indexs_list: ts_url = "https" + k + ".ts" c = get_page(ts_url, i) task = asyncio.ensure_future(c) stasks.append(task) print(f"{i}下载完成")loop = asyncio.get_event_loop()# 需要将任务列表封装到wait中loop.run_until_complete(asyncio.wait(stasks))
二、普通顺序处理：
# coding:utf-8import requestsimport refrom openpyxl import load_workbookheaders = { "User-Agent": "Mozilla/5.0(Windows NT 6.1;WOW64) AppleWebKit/537.36(KABUL, like Gecko) " "Chrome/86.0.4240.198Safari/537.36 " }wk = load_workbook(r"E:\project\project03\m3u8 - 副本 (2).xlsx")sheet = wk.activefor i, j in zip(sheet["A"], sheet["B"]): # print(j.value) print(f"正在下载{i.value}集", end=" ") resp = requests.get(j.value, headers=headers) data = resp.text # print(data) indexs_list = re.findall(r'https(.*?).ts', data) for k in indexs_list: ts_url = "https" + k + ".ts" res = requests.get(ts_url, headers=headers) data = res.content with open(f"{i.value}.mp4", "ab+") as f: f.write(data) f.flush() print("下载完毕")wk.close()
