PHP cURL 后数据未发送到目标 url

Question

Maybe it's duplicate question. I have tried any solution with similar question with mine that I can find and implemented it to my probs, not a single solution is work. I need to use PHP curl to get data from other systems (B). But in the B the data I sent is not defined or no data was sent. curl process is success target url is just right.

Curl in my system

$data['tag']    = 'getData';
$data['periode'] = $this->input->post('periode');
$url = 'http://example.com/service/index.php';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, sizeof($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// I use follow location cause I get moved permanently notice
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$output = curl_exec($ch);
curl_close($ch);

echo $output;

And in B system I check with this

var_dump($_POST);

the ouput is array(0) {} .

Answer 1

You need to use CURLOPT_POSTFIELDS in a query string format.

curl_setopt($ch, CURLOPT_POSTFIELDS, "tag=val&periode=val");

Also you should just be setting CURLOPT_POST to 1 as it just specifies if it should use a POST request.

You can use https://www.php.net/manual/en/function.http-build-query.php to build a query string from an array.

Answer 2

I have my own solution for this. I just need to set the URL to https insetad of http , because the backend program is redirecting all the non secure protocol http to the secure one https .
