Mysql Read HTTP URL

Question

I would like mysql to read a url through a SELECT

I searched and saw that you have an answer here.

I did the whole procedure as it is in this link, but to no avail

select would call the url as in this example here

SELECT http_get('<url>');
SELECT http_post('<url>', '<data>');
SELECT http_put('<url>', '<data>');
SELECT http_delete('<url>');

Installation is for windows

Something else is missing?
