####通过时间，为下载的文件命名
def get_filename():
    return datetime.now().strftime("%Y-%m-%d-%H-%M-%S-%f")


if __name__ == '__main__':

    # print(get_filename()
    page_size=int(input("请输入你要下载的视频数量: "))
    ###为了反爬，模拟
    header = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36"

                          f"pageNo=0&pageSize={page_size}&subjectId=76",headers=header)
    ####如果服务端返回的是字符，则用text
    ####如果服务端返回的是视频、图片、mp3 等等，这种二进制的用content
    res_dict = json.loads(res_data.text)
    # print(res_dict["data"])
    for item in res_dict["data"]:
        # print(item["playUrl"])
        video_url=item.get("playUrl","")

        #####以下方法局限性能问题，同时没有进度条++++++++++++++++++++++++++++++++++++++
        # video_data=requests.get(video_url,headers=header)
        #
        # with open(f"download_video/{get_filename()}.mp4","wb") as f:
        #     f.write(video_data.content)
        #
        #######以下方法加进度条和指定下载流大小++++++++++++++++++++++++++++++++++++++++
        video_data=requests.get(video_url,headers=header,stream=True)
        if "content-length" in video_data.headers:
            ###获取了视频的大小，大小为b
            content_size=int(video_data.headers["content-length"])
            video_name=get_filename() + ".mp4"

        with open(f"download_video/{get_filename()}.mp4","wb") as f,tqdm(desc=video_name,total=content_size) as bar:
            for chunk in video_data.iter_content(chunk_size=1024):
                if chunk:
                    f.write(chunk)
                    bar.update(len(chunk))
