3.4 多线程

代码

py 复制代码 
import concurrent.futures
import requests

# 定义一个下载函数
def download_video(URL):
    url, index, name = URL.split(" ", 2)
    videoDownload3(url,index,name)

def THREAD(URLS):
    # 创建线程池，指定线程数量
    max_workers = 10  # 这里设置线程数量，根据需要进行调整
    with concurrent.futures.ThreadPoolExecutor(max_workers=max_workers) as executor:
        # 提交下载任务给线程池处理
        futures = [executor.submit(download_video, URL) for URL in URLS]

        # 等待所有任务完成
        for future in concurrent.futures.as_completed(futures):
            try:
                future.result()  # 获取任务的结果（这里不需要结果）
            except Exception as e:
                print(f"An error occurred: {e}")

3.5 结果

py 复制代码 
url_model = "https://space.bilibili.com/471303350/channel/collectiondetail?sid=1278346 3"
value = url_model.split(' ')
url = value[0]
model = value[1]

if model == "1":
    videoDownload1(url)
    print("下载完成")
if model == "2":
    # 接口分析
    # 点进去的话接口
    # https://www.bilibili.com/video/BV1qW4y1a7fU/?spm_id_from=333.337.search-card.all.click
    # 点击视频的话就这样
    # https://www.bilibili.com/video/BV1qW4y1a7fU?p=1
    # https://www.bilibili.com/video/BV1qW4y1a7fU?p=2&vd_source=de2dcd0f37ff916ec3f8fb83c6366123
    # 可以发现不同的集的接口格式应该是这样的，p = 几就是第几集
    # https://www.bilibili.com/video/BV1qW4y1a7fU?p=1

    # 查看有多少集
    # 一种是视频选集那块会写有多少个
    # 获取源码
    urls = getUrls2(url)
    i = 1
    for index,url in enumerate(urls):
        videoDownload2(url,index)

    print("下载完成")
if model == "3":
    # 接口分析
    # 视频合计每个视频接口没有规律，然后再播放页中网页没有直接的播放链接，所以就用合集页的链接来分析
    # 网页里面的每个链接都是动态加载的，需要访问json数据获取，也或者用虚拟浏览器那种等页面加载完成后访问(这种以后可能会更新，感觉这个有点麻烦)，
    # 这里是用json数据做的
    # https://space.bilibili.com/107762251/channel/collectiondetail?sid=877119
    # https://api.bilibili.com/x/polymer/web-space/seasons_archives_list?mid=107762251&season_id=877119&sort_reverse=false&page_num=1&page_size=30
    # https://space.bilibili.com/389199842/channel/collectiondetail?sid=1275285
    # https://api.bilibili.com/x/polymer/web-space/seasons_archives_list?mid=389199842&season_id=1275285&sort_reverse=false&page_num=1&page_size=30
    # 这是两个接口，前面那个数字是用户，后面那个数字代表的是合集，下载的接口其实是股东

    urls,name = getUrls3(url)
    # print(len(urls))
    for index,url in enumerate(urls):
        # print(url)
        videoDownload3(url,index,name)
    # print(urls)
    # 多线程
    # for index,url in enumerate(urls):
    #     URLS.append(url + " " + str(index) + " " + name)
    #     THREAD(URLS)

那切里做展示，有些合集下载时候有点bug，还没找到问题，可以下载，但是保存路径有点问题，应该是和命令行冲突了，我就不改了
