question
I encountered the above problem when my mysql entered data
I uploaded a 10m clip to an editor, and the network address generated by the editor is data:base64
, and then it does not enter the data database
. What is the problem with this problem?

exceeds the length of the field, right? 10m is equivalent to 10485760 bytes, and fields of type Varchar should not be able to handle this task.
in fact, you have been struggling in the wrong direction, the right way is to upload the image to the image server, the editor only saves the image path, not the current Base64. If you look for other open source Editor, you need to automatically upload the image (configure the upload path) after dragging the image, and then fill in the image path into the editor.

Froala Editor uploads pictures to his server in the editor

if someone is struggling with this problem, here is the fix:

attempt to change / configure wait_timeout my.cnf profile in your mysql:

wait_timeout=3600

this profile is located at / etc/mysql/my.cnf (Ubuntu/Debian) and `usr/local/mysql/my.cnf (OSX).

restart the mysql server and it should work.

Why not upload a picture as big as this to the file server?
