How can I get PHP data from Azuracast API json output? - php

Question

I tried very hard to make output of Azuracast json query, but I cant, I'm a php guy and I don't quite get it. Tutorials didn't work either.
I got my token and eveyrthing. I just want to output a album name, song title and artist to string. That's it. I just want to make my little custom player, which is going well except for this. Can you guys check my code and help me out? I know this questions was already answered, but it didnt help for me. It always outputs nothing on my website.
my api link: here
//$url = "https://91.247.70.40/api/nowplaying/2.json";
//$data = file_get_contents($url);
//$infos = json_decode($data, true);
//$nazwa = $infos->cache;
//echo $nazwa;
function jwt_request($token, $post) {
$ch = curl_init('https://91.247.70.40/api/nowplaying/2');
header('Content-Type: application/json');
$post = json_encode($post);
$authorization = "Authorization: Bearer ".$token;
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json' , $authorization ));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result, true);
}
echo $result->cache;
you can see i tried two ways. None worked. I've hidden the token. It is set up correctly, i know that.

You seem to be having multiple problems here. The first one is that your API is served on HTTPS but with an invalid certificate / self signed one. file_get_contents and curl will by default fail requests to pages with an untrusted cert. First you should setup a Let's Encrypt certificate as shown in the documentation.
Then your first code will correctly return the decoded JSON data. But you should remove the .json at the end of the URL since this is not a file you are requesting but an API route. There you try to access the decoded data as if it is an object but json_decode($data, true) returns an assoc array so you need to access the data like this $infos['cache']. If you want to get the album name, song title and artist from the data you need to access these fields: $infos['now_playing']['song']['album'], $infos['now_playing']['song']['title'] and $infos['now_playing']['song']['artist'].
Your second code example will not work after you fixed the certificate error because the /api/nowplaying/{station_id} route is a GET route but you define the CURL request as a POST request.
