[SOLVED] I'm having difficulty getting a JSON in a URL with PHP. Can you help me?

Issue

I'm trying to get JSON from a URL using the codes below. I always get the errors below.

<?php
$url = ...;
$json = file_get_contents($url);
$dados = json_decode($json, true);
echo "<pre>";
print_r($dados);
?>

Error:

Warning: file_get_contents(https://www.car.gov.br/publico/imoveis/getImovel?lat=-2.449376438504347&lng=-49.04754638759188): Failed to open stream: Redirection limit reached, aborting in ... on line 5

Another code used:

<?php
$url = ...;
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$dados = curl_exec($ch);
curl_close($ch);
echo "<pre>";
var_dump(json_decode($dados, true));
?>

Response:

NULL

When using the same code, with another URL, such as:

$url = 'http://api.ipstack.com/177.194.116.144?access_key=65a2a7545d3ea66448ca270dad2dc789'

the feedback works correctly.

Can you help me?

Solution

The following seems to work

Using curl:

    <?php
    
    $url = 'https://www.car.gov.br/publico/imoveis/getImovel?lat=-2.449376438504347&lng=-49.04754638759188';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:90.0) Gecko/20100101 Firefox/90.0',
    'Accept-Encoding: gzip, deflate',
    'Accept-Language: en-US,en;q=0.5',

    'Pragma: no-cache',
    'Cache-Control: no-cache',    
    ));
    

curl_setopt($ch, CURLOPT_VERBOSE, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$dados = curl_exec($ch);
$error = curl_error($ch);
    
    ?>

Without the proper headers the server responds with an empty body. So make sure you set them before making a request.
