`TencentClassDownloader` 2 | 腾讯课堂视频下载脚本 3 | 4 | 视频教程:[大型纪录片：腾讯课堂关服了，课程保存方法快来学习，超级简单 5 | ](https://www.bilibili.com/video/BV1uTvCeDEjk) 6 | 7 | # 开始 8 | ## 1、配置环境(两种方式) 9 | 10 | ### ①Python环境运行 11 | 12 | 运行环境 Python3,我测试时的版本是Python3.8 13 | 14 | #### 安装依赖 15 | ``` 16 | pip install -r requirements.txt 17 | ``` 18 | 19 | ### ②直接运行 20 | 21 | 配置好cookie和config.conf,直接运行目录下的main.exe 22 | 23 | 24 | ## 2、获取cookie 25 | 以谷歌浏览器为例，打开腾讯视频并登陆，键盘F12，找到network——点击Doc（如果没有数据，刷新一下界面），找到cookie等信息，拷贝粘贴到目录下的cookie文件中 26 | 27 | 28 | ## 3、配置conf 29 | 修改目录中到config.conf文件， 30 | 31 | ``` 32 | [QQ] # 你当前课程所属的QQ号 33 | number = 123456789 34 | 35 | [url] # 课程链接，一定要按照 https://ke.qq.com/webcourse/xxxxx/xxxxx形式粘贴 36 | url = https://ke.qq.com/webcourse/12345678/123456789 37 | 38 | [process] # 下载视频的线程数，视你电脑能力而定，可以尽量多开一些 39 | process_num = 8 40 | 41 | [output] # 下载视频存放的路径 42 | save_path = D:\\txktDownload\ 43 | 44 | [clarity] # 清晰度，目前只设置了 1 2 3 三种，其中 1 为最清晰， 3为最不清晰， 2为两者之间， 实际情况看你的课程支持哪些清晰度。 45 | clarity = 1 46 | ``` 47 | 48 | 49 | ## 4、运行main.py或者main.exe 50 | ``` 51 | python3 main.py 52 | 或 53 | main.exe 54 | ``` 55 | 等着下载完成就可以了，下载过的视频会自动跳过，如需重新下载请删除原来的视频。 56 | 57 | # 结束 58 | 59 | 交流群[https://t.me/teleportmmm]
