Thanks a bunch for your consistent help. The web json is working for me now just like you told me to fetch previously. Here is a snippet in case it could help someone else.
outputmacro: ^testing()
$user_agent = ^"User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)"
$url = ^join(https://api.github.com/users/test/repos) # limit 1000 requests/day
$jsonid2 = ^jsonopen(GET $url "" $user_agent)
$answer = ^jsonpath("[0].owner.id" $jsonid2)
if (!$answer) {
there is no result
}
else
{
the result is $answer
}
Thanks.
