要学一些东西，但腾讯课堂不支持自定义变速，播放时有水印，且有些老师的课一遍不够看，于是这个脚本诞生了。
时间比较紧张，只会不定时修复重大bug。多线程下载之类的功能更新短期内不会有，如果你想一起完善这个脚本，欢迎pr

报这个错误，这是什么原因呀 拉取的最新代码的
https://ke.qq.com/cgi-bin/course/basic_info?cid= 上面这个接口要带防盗链，不然查询不到参数 错误的返回：{"msg":"refer错误","type":1,"retcode":100101}
建议解决办法：
在utils.py文件里，的get_course_from_api函数中，添加headers参数
如：
'''
headers = {
'referer': 'https://ke.qq.com/user/index/index.html',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) '
'Chrome/80.0.3987.132 Safari/537.36 '
}
'''
即可
完整函数： ''' python def get_course_from_api(cid=None): headers = { 'referer': 'https://ke.qq.com/user/index/index.html', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) ' 'Chrome/80.0.3987.132 Safari/537.36 ' } # 获取课程信息 if cid is None: print('请输入cid！') url = 'https://ke.qq.com/cgi-bin/course/basic_info?cid=' + str(cid) response = requests.get(url=url, headers=headers).json() name = response.get('result').get('course_detail').get('name').replace('/', '／').replace('\', '＼') with open(name + '.json', 'w') as f: f.write(json.dumps(response)) return name '''

使用过程中会出现这个
因为课程内容大小不一样 重复这个过程最多能够下载完成3个视频 但是剩下的就怎么都下载不完了 有的章节10来个视频呢
如果使用下载课程全部视频 会继续上面的那个错误跳到下个章节序列继续下载 但是也是下载不全 不知道怎么解决
def run_shell(shell, retry=True, retry_times=3): cmd = subprocess.Popen( shell, close_fds=True, shell=True, bufsize=1, stderr=subprocess.DEVNULL, stdout=subprocess.DEVNULL, )
if retry and cmd.returncode != 0:
time.sleep(1)
if retry_times > 0:
return run_shell(shell, retry=True, retry_times=retry_times - 1)
print('\nShell出现异常，请自行查看课程文件是否转码成功')
return cmd.returncode
我感觉是不是这个地方有问题造成的 是不是def run_shell(shell, retry=True, retry_times=3): 这个retry_times=3 值修改大一点?
#55 问题已经解决了。
