PHP cURL 内容类型未设置

Question

I'm trying all solutions on the full internet and I can't get it.

I'm trying to connect using php curl to an external API sending json data, but I can't set content_type.

$url = "https://example.com:xxxx/api/example";

$data = array(
    'example' => '1',
    'example2' => '2'
);
$jsonData = json_encode($data);

$ch = curl_init($url);

if(extension_loaded('curl') == true){
    echo('Curl is active<br/>');
} else {
    echo('Curl is NOT active<br/>');
}

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type:application/json',
    'Connection: Keep-Alive'
));
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 300); //timeout in seconds
$result = curl_exec($ch);


echo('<hr/>');
var_dump(curl_getinfo($ch));
echo('<br/>');
echo curl_errno($ch) . '<br/>';
echo curl_error($ch) . '<br/>';
echo('<hr/>');


curl_close($ch);

echo('<br/>Response: ');
var_dump($result);

Response:

Curl is active

array(26) { ["url"]=> string(66) " https://example.com:port/api/example " ["content_type"]=> NULL ["http_code"]=> int(0) ["header_size"]=> int(0) ["request_size"]=> int(0) ["filetime"]=> int(-1) ["ssl_verify_result"]=> int(0) ["redirect_count"]=> int(0) ["total_time"]=> float(0.467581) ["namelookup_time"]=> float(0.004158) ["connect_time"]=> float(0) ["pretransfer_time"]=> float(0) ["size_upload"]=> float(0) ["size_download"]=> float(0) ["speed_download"]=> float(0) ["speed_upload"]=> float(0) ["download_content_length"]=> float(-1) ["upload_content_length"]=> float(-1) ["starttransfer_time"]=> float(0) ["redirect_time"]=> float(0) ["redirect_url"]=> string(0) "" ["primary_ip"]=> string(0) "" ["certinfo"]=> array(0) { } ["primary_port"]=> int(0) ["local_ip"]=> string(0) "" ["local_port"]=> int(0) }
