使用 PHP 使用 REST API 身份验证错误连接到 VCenter

Question

I followed the instructions in the official vsphere site to get info from the server and from the answer of another user here . From what I have understood, firstly I have to get the session id (cis id), but I got "null" as a result.

I tried multiple codes but the result is the same:

$ch = curl_init();

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $headers = array(
            'Content-Type: application/json',
            'Accept: application/json',
            'vmware-use-header-authn: test'
        );
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, "https://vcsa/rest/com/vmware/cis/session");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_USERPWD, 'administrator@vs.dom:userpassword');
        curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC );

$out = json_decode(curl_exec($ch));
// var_dump($out);
if ($out === false) {
    echo 'Curl Error: ' . curl_error($ch);
    exit;
}
$sid = $out;
        dd($out);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("vmware-api-session-id:$sid"));
curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch, CURLOPT_URL, "https://vcsa/rest/vcenter/vm");

$output = curl_exec($ch);
$vms = json_decode($output);
var_dump($vms);

curl_close($ch);

The result is null.

Answer 1

when you debug your code, the $out variable return null? If yes, can you check if your curl returns 56 - OpenSSL SSL_read: Success error in $out = json_decode(curl_exec($ch)); ?

This error occoured with my code, and I see wich cURL in 7.67 version cause this trouble.

My solution was to downgrade cURL version to 7.65.

It works for me!

Answer 2

I had the same problem, and eventually understood that it is caused by this header:

curl_setopt($ch, CURLOPT_POST, true);

And replacing it with this one solves the issue:

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');

Answer 3

this is a script word 100% using PHP

 <?php $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_URL, "https://{ip}/rest/com/vmware/cis/session"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_USERPWD, 'username'. ":". 'password'); $out = json_decode(curl_exec($ch)); // var_dump($out); if ($out === false) { echo 'Curl Error: '. curl_error($ch); exit; } $sid = $out->value; curl_setopt($ch, CURLOPT_HTTPHEADER, array("vmware-api-session-id:$sid")); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch, CURLOPT_URL, "https://{ip}/rest/vcenter/vm"); $output = curl_exec($ch); $vms = json_decode($output); var_dump($vms); curl_close($ch); ?>
