Wikipedia Api request fail [Solved]

Can someone help me with my Wikipedia viewer. I found in the forum some tips but my api still doesn’t work. What i wrong?

I try to delete this post because i solved but i don’t know how. I solve it but i change the request in this: "https://en.wikipedia.org/w/api.php?action=opensearch&search="+searchKeys+"&format=json&callback=?"

from this (that i prefer for the response): “https://en.wikipedia.org/w/api.php?action=query&format=json&list=search&srsearch=” + searchKeys .
