Answer 1

The error is explicit, Json in data isn't a valid Json. Can you print the data content ?
But I see you didn't check the status, so you don't know if the get method have success or not.
The first for do anything ?
BTW, You have space in your url it's a mistake ?
/java 2015 v0/admin/code%20php/code_produits.php?idca=
