I'm trying to make a POST request from the portal with the following code. And got above error in browser. I'm using PHP 7.4,Apache 2.4.6 version.
I see some answer say to use CURLOPT_FOLLOWLOCATION or cookies and I try it but I cannot figure out how to do. Please some help is really appreciated.

Answer 1

Yes, using CURLOPT_FOLLOWLOCATION is the correct answer
follow this example to see if it work for you
$cookie_file_path = "/toyourfile";
$data = array(
"data1" => "1000",
);
$data_string = json_encode($data);
$ch = curl_init("http://www.example.com/api/info/getPlan");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path);
//curl_setopt($ch, CURLOPT_VERBOSE, true); // if you run on commandline this will print out more information for you
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json",
"Content-Length: " . strlen($data_string))
);
$result = curl_exec($ch);
