* If you want to protect the file link, you need to set protect_file_link to true. At this time, if you want to perform external playback and other operations, you need to replace host with user: pass @ host
* No need for Basic Auth disk, just keep user and pass empty at the same time. (No need to set it directly)
* [Note] For the disk whose id is set to the subfolder id, the search function will not be supported (it does not affect other disks).
