How to pass client certificate through HTTP Client in php laravel 8 - php

Question

How to pass client certificate (2 files .key and .pem) through http client request?
I need to include those files in the below http post request to be able to talk with the server.
$response = Http::post('https://domainname.com/api/client/session', array('xxx' => array('xx' => 'xxxx')));
I am able to do it using phpCurl like below:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => '',
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => $type,
CURLOPT_POSTFIELDS => $body,
CURLOPT_HTTPHEADER => $header,
CURLOPT_SSLKEY => $pemPath,
CURLOPT_SSLCERT => $crtPath,
// CURLOPT_NOSIGNAL => 1
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
echo (json_encode($response));
echo ("\n\n");
if ($err) {
return ["success" => false, "message" => $err];
} else {
return ["success" => true, "data" => json_decode($response)];
}
But I need to do it using Http Client for many other purposes. Any suggestion?

You can use Guzzle options provided by http client
$response = Http::withOptions([
'ssl_key' => ['/path/to/cert.pem', 'password.key']
])->post('https://domainname.com/api/client/session');
It would be same as using ssl_key request option for guzzle http client instance directly.
use GuzzleHttp\Client;
$client = new Client();
$client->request('POST', 'https://domainname.com/api/client/session', [
'ssl_key' => ['/path/to/cert.pem', 'password.key']
]);
