I am currently developing an integration system between Moodle and JupyterHub. One of the functions of the system is to hook jupyter's WebSocket communication and display the learning progress in Moodle.
https://gitlab.nsl.tuis.ac.jp/iseki/lticontainerspawner/-/wikis/Moodle-+-JupyterHub https://gitlab.nsl.tuis.ac.jp/iseki/mod_lticontainer/-/wikis/mod_lticontainer
However, starting with v4.0 of JupyterLab, WebSocket communications are prefixed with binary data starting with 0x06 0x00.
ex.)
06 00 00 00 00 00 00 00 -+ 38 00 00 00 00 00 00 00 | 3d 00 00 00 00 00 00 00 | 06 01 00 00 00 00 00 00 |-- here format? e2 01 00 00 00 00 00 00 | e4 01 00 00 00 00 00 00 | ff 01 00 00 00 00 00 00 -+ 69 6f 70 75 62 7b 22 6d 73 67 5f 69 64 22 3a 20 22 30 33 34 64 65 34 61 62 2d 35 32 63 37 33 32
If anyone knows where I can find some information about the format of this data, please let me know.
I have searched around the following URL, but have not found any information on binary data
https://jupyter-client.readthedocs.io/en/latest/messaging.html
I need to know the format of the binary communication data added in JupyterLab 4.
Best Regards,
