Problem with Bearer Authorization token in php curl

When I try to post data with bearer token on https://reqbin.com there is no error. But I copy the code:
<?php
$url = "https://api.real-debrid.com/rest/1.0/unrestrict/link";
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);;
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$headers = array();
$headers["Authorization"] = "Bearer ZWP53ALWWN7*******GZHE66Z6BL54FV4Z2DWNS22URJUX6Q";
$headers["Content-Type"] = "text/plain";
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$data = "link=https://rapidgator.net/file/6e3e93b5c15700c574b4313de8ad416f/";
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$resp = curl_exec($curl);
curl_close($curl);
var_dump($resp);
?>
and try to run on my servers I get this error.
string(43) "{ "error": "bad_token", "error_code": 8 }"

What is wrong with this code. it shows "msg is null"

This the code.
$data = '{"rewardTime":"20","articleTime":"0","rewardType":"copper_treasure_chest","activeDay":"17","videoTime":"20","specific":"false","userid":"2944210","version":"3","day":"2020-05-07","token":"M2U4ZjQyMWItZmNiYi00NWM4LWJhYWYtOTZhZWEwY2ExODY5"}';
$url = 'https://api.cc.clipclaps.tv/reading/obtainReward';
$curl = curl_init();
curl_setopt($curl, CURLOPT_PORT, 443);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_ENCODING, "");
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
$result = json_decode($result, true);
echo "$result"."\n";
This is the result:
{"code":4009,"msg":null,"data":null,"date":1588991702039}
It should be msg: success
You would need to refer to the API's documentation to figure out what Error: 4009 is exactly.
Your code (Curl request) is working, as it is receiving a proper JSON response.. and there is no coding error that I see.
Why the API is responding with an empty result/data field, is specific to the API itself.

How to make website authorization using curl and php?

I'm trying to realize a simple authorization using login and password. I get a cookie but not sure if authorized or not (how to check?), also I am trying to redirect after authorization but as a result, I get Error 404 after my code tried to redirect (followlocation, true).
Here's my php code
Trying just to redirect but 404 occurred.
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($curl);
echo $result;
curl_close($curl);
And here's trying to authorize, not sure if it works (but I get cookie and in header I get 200 OK)
$loginData = [
urlencode('j_username') => 'someName',
urlencode('j_password') => 'somePassword'
];
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_VERBOSE, 2);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($loginData));
curl_setopt($curl, CURLOPT_COOKIEJAR, $_SERVER['DOCUMENT_ROOT'].'/authCookie.txt');
curl_setopt($curl, CURLOPT_COOKIEFILE, $_SERVER['DOCUMENT_ROOT'].'/authCookie.txt');
$result = curl_exec($curl);
echo $result;
curl_close($curl);
Also, I use urlencode but not sure if I use it in the right way (I have it in curl like $curl --location --request POST 'http://someFullName' \ --data-urlencode 'j_username=someUsername' \ --data-urlencode 'j_password=somePassword')
for auth you can use http basic auth it very simple in use for client and server, client code in this case will be look like:
<?php
const COOKIE_FILE = '/tmp/authCookie';
$host = 'localhost';
$username = 'login';
$password = 'pass';
$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_USERPWD, sprintf('%s:%s', $username, $password));
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);
curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_FILE);
$return = curl_exec($ch);
curl_close($ch);
about your 4xx error, i think you have problems with server, for test redirections you can do something like:
<?php
//stable route with redirect
$host = 'https://bitly.is/EnterpriseButton';
$userAgent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:76.0) Gecko/20100101 Firefox/76.0';
$curl = curl_init($host);
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, $host);
//with enabled followlocation
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_HEADER, true);
$result = curl_exec($curl);
curl_close($curl);
var_dump($result);
$curl = curl_init($host);
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, $host);
//with disabled followlocation
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($curl, CURLOPT_HEADER, true);
$result = curl_exec($curl);
curl_close($curl);
var_dump($result);
and for check auth work you can auth through browser with cookies from curl

How to debug a get request in php using curl

I'm trying to make a get request in php using curl. This is what I'm doing:
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "username:password");
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
printf($result);
But $result doesn't print out anything, no success or failure message. I've successfully reached the endpoint via postman and in a web browser so I know it works. Printing out $curl prints: "Resource #1" which makes me think curl is properly installed on the server.
I'm not sure what steps to take next to make things work.
Add a few more option for troubleshooting purposes.
Check for an error response.
If no error, get the details:
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT,10);
curl_setopt($ch, CURLOPT_FAILONERROR,true);
curl_setopt($ch, CURLOPT_ENCODING,"");
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$data = curl_exec($ch);
if (curl_errno($ch)){
$data .= 'Retreive Base Page Error: ' . curl_error($ch);
}
else {
$skip = intval(curl_getinfo($ch, CURLINFO_HEADER_SIZE));
$head = substr($data,0,$skip);
$data = substr($data,$skip);
$info = curl_getinfo($ch);
$info = var_export($info,true);
}
echo $head;
echo $info;
You can utilize curl's CURLOPT_VERBOSE and CURLOPT_STDERR like this:
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "username:password");
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$verbose = fopen('php://temp', 'w+');
curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_STDERR, $verbose);
$result = curl_exec($curl);
curl_close($curl);
rewind($verbose);
$verboseLog = stream_get_contents($verbose);
echo "Verbose information:\n<pre>", htmlspecialchars($verboseLog), "</pre>\n";
printf($result);

openssl_get_publickey() and curl "unable to use client certificate"

I got following code..
<?php
error_reporting(E_ALL);
ini_set('display_errors',1);
$keystore = '/var/www/html/key.pem';
$url = 'https://myurl';
$keystorepassword = '123';
$key2 = "/var/www/html/public.pem";
$handler = fopen($key2, "r");
$kkey = fread($handler, 8192);
fclose($handler);
$pubkey = openssl_get_publickey($kkey);
openssl_free_key($pubkey);
$curl = curl_init();
curl_setopt($curl, CURLOPT_VERBOSE, TRUE);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
//curl_setopt($curl, CURLOPT_SSLVERSION,3);
curl_setopt($curl, CURLOPT_SSLCERT, $keystore);
curl_setopt($curl, CURLOPT_SSLKEYPASSWD, $keystorepassword);
curl_setopt($curl, CURLOPT_POSTFIELDS, 'data');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$result =curl_exec ($curl);
var_dump($result);
if(curl_error($curl)){
$result = curl_error($curl);
var_dump($result);
}
curl_close ($curl);
?>
And it returns "unable to use client certificate (no key found or wrong pass phrase?)".
If i comment line "$pubkey = openssl_get_publickey($kkey);", then curl works fine.
Is there any chance, that "something" stays in memory and curl uses it?
