Conflict with the "slash" in a base64 string of an image

1

I am sending a image file base64 string from ajax (post), but the “slash” it contains conflicts with the path. What is the way to send a base64 through slim routing?. Thank you.

Do you send the base64 data in the url?
Just send it via POST within the request body.
