凭据配置文件

默认配置文件路径:
Windows:
%APPDATA%\bilibili-subtitle-fetch\config.tomlLinux/macOS:
~/.config/bilibili-subtitle-fetch/config.toml

sessdata- 访问需要登录态的字幕接口时必需bili_jct- 自动刷新时必需ac_time_value- 自动刷新时必需buvid3、buvid4、dedeuserid- 可选,但建议一并保存
当 sessdata、bili_jct 和 ac_time_value 都存在时,服务会在发起需要登录态的请求前自动检查是否需要刷新 Cookie,并将新值回写到 config.toml,不需要手动执行刷新命令。
