【python】网易云音乐缓存.uc转化MP3
如题，Python实现的将网易云的缓存文件.uc转化为MP3格式，解密.uc格式的方法是将每个字节跟0xA3异或。
import os
def get_path_dfs_helper(path_collect_list: list, input_path: str, deep: int):
if not os.path.exists(input_path):
print(f'目录不存在:{input_path}')
return

return
if os.path.isfile(input_path):
path_collect_list.append(input_path)
return
files = os.listdir(input_path)
for file in files:
f_abs = os.path.join(input_path, file)
get_path_dfs_helper(path_collect_list, f_abs, deep + 1)
pass

get_path_dfs_helper(cache_file_list, input_dir, 0)
for f in cache_file_list:
if not f.endswith('.uc'):
