How to use the Medulla XML-RPC API

This guide will help users utilize Medulla's XML-RPC API: Medulla's XML-RPC API.php

1: Configuration
Check the following:
  • SSL Certificate: Download the certificate from the Medulla server:http://<medulla_server>/downloads/medulla-ca-chain.cert.pem
  • Install the certificate on the server that will be querying the API 
    • For Debian-based systems, copy the file to/usr/local/share/ca-certificatesand change its extension to crt, then import the certificate by running theupdate-ca-certificatescommand
    • For RedHat-based systems, copy the file to/etc/pki/ca-trust/source/anchorsand change its extension to crt, then import the certificate by running theupdate-ca-trust extractcommand
  • If necessary, add the IP address and hostname of the XML-RPC server to /etc/hosts

2: Using the API
First authenticate the user and retrieve the session cookie:
/**
 * Executes an XML-RPC request.
 *
 * @param string $method The name of the XML-RPC method to call.
 * @param array $params The parameters to pass to the method.
 * @param bool $includeCookie Indicates whether the session cookie should be included in the request.
 * @return array An array containing the HTTP headers and the body of the response.
 * @throws Exception If an error occurs while connecting or sending the request.
 */
function executeRequest($method, $params, $includeCookie = false) {
    $agentInfo = $_SESSION["XMLRPC_agent"];
    $requestXml = xmlrpc_encode_request($method, $params, ['output_type' => 'php', 'verbosity' => 'pretty', 'encoding' => 'UTF-8']);

    // Set the HTTP headers
    $url = "/";
    $httpQuery  = "POST " . $url . " HTTP/1.0\r\n";
    $httpQuery .= "User-Agent: MMC web interface\r\n";
    $httpQuery .= "Host: " . $agentInfo["host"] . ":" . $agentInfo["port"] . "\r\n";
    $httpQuery .= "Content-Type: text/xml\r\n";
    $httpQuery .= "Content-Length: " . strlen($requestXml) . "\r\n";
    // Add the cookie if necessary
    if ($includeCookie) {
        $httpQuery .= "Cookie: " . $_SESSION['cookie'] . "\r\n";
    }
    $httpQuery .= "Authorization: Basic " . base64_encode($agentInfo["login"] . ":" . $agentInfo["password"]) . "\r\n\r\n";
    $httpQuery .= $requestXml;

    // Configure the SSL context
    // 'allow_self_signed' is set to false to accept only certificates signed by a recognized certificate authority
    // 'verify_peer' is set to true to verify the server's SSL certificate
    $context = stream_context_create();
    $proto = $agentInfo["scheme"] == "https" ? "ssl://" : "";
    if ($proto) {
        stream_context_set_option($context, "ssl", "allow_self_signed", false);
        stream_context_set_option($context, "ssl", "verify_peer", true);
    }

    // Open the connection to the server
    $socket = stream_socket_client($proto . $agentInfo["host"] . ":" . $agentInfo["port"], $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $context);
    if (!$socket) {
        throw new Exception("Unable to connect to XML-RPC server: $errstr ($errno)");
    }

    // Set a 60-second timeout for reading
    stream_set_timeout($socket, 60);

    if (!fwrite($socket, $httpQuery)) {
        throw new Exception("Unable to send data to XML-RPC server");
    }

    $responseXml = '';
    while (!feof($socket)) {
        $ret = fgets($socket, 128);
        $responseXml .= $ret;
    }
    fclose($socket);

    // Separate the HTTP headers from the response body
    list($headers, $body) = explode("\r\n\r\n", $responseXml, 2);
    return [$headers, $body];
}

/**
 * Authenticates the user and retrieves the session cookie.
 * @param string $method The name of the XML-RPC method to call.
 * @param array $params The parameters to pass to the method.
 * @return string The session cookie.
 * @throws Exception If an error occurs during authentication.
 */
function authenticateAndGetCookie($method, $params) {
    list($headers, $body) = executeRequest($method, $params);

    // Parse the HTTP headers to extract the session cookie
    $headers_array = array();
    $header_lines = explode("\r\n", $headers);
    foreach ($header_lines as $header) {
        $parts = explode(': ', $header, 2);
        if (count($parts) == 2) {
            $headers_array[$parts[0]] = $parts[1];
        }
    }

    // Using the parsed headers
    if (isset($headers_array['Set-Cookie'])) {
        $cookie = $headers_array['Set-Cookie'];
        $_SESSION['cookie'] = $cookie;
    } else {
        throw new Exception('Authentication failed, no cookie received');
    }

    return $cookie;
}

3: Examples of requests
  • Get the list of all packages
/**
 * Sends an XML-RPC request and returns the response only if authenticated by cookie.
 * @param string $method The name of the XML-RPC method to call.
 * @param array $params The parameters to pass to the method.
 * @return array The XML-RPC response.
 * @throws Exception If an error occurs while sending the request.
 */
function sendXmlRpcRequest($method, $params) {
    list($headers, $body) = executeRequest($method, $params, true);
    $responseXml = substr($body, strpos($body, '<?xml'));
    $response = xmlrpc_decode($responseXml, 'UTF-8');
    if (is_array($response) && xmlrpc_is_fault($response)) {
        throw new Exception("XML-RPC fault: {$response['faultString']} ({$response['faultCode']})");
    }
    return $response;
}

    $method = "pkgs.get_all_packages";
    $params = [
        'root', // login
        false,  // sharing_activated
        0,      // start
        10,      // end
        [
            'filter' => 'hostname', // example name of package
        ] // ctx
    ];

    try {
        $responseXml = sendXmlRpcRequest($method, $params);

    } catch (Exception $e) {
        echo "Error: " . $e->getMessage();
    }
Tips: To get the package UUID: $responseXml['datas']['uuid'][$key]

  • Get the list of all machines
$method = "xmppmaster.get_machines_list";
$params = [
     0, // start
     20, // end
     [
        'filter' => '',
        'field' => 'allchamp',
        'computerpresence' => 'presence', // Specify whether to include machines that are present
        // 'computerpresence' => 'no_presence', // Specify whether to include non-present machines
        'location' => "UUID0", // glpi_id - entity
    ] // ctx
];

try {
    $responseXml = sendXmlRpcRequest($method, $params);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

  • Get a machine's details
$method = "glpi.getLastMachineInventoryPart";
$params = [
     $uuid,
     'Summary',
      0, // minbound
      0, // maxbound
      "", // filter
      [
           "hide_win_updates" => false,
           "history_delta" => false
       ], // options
];

try {
    $responseXml = sendXmlRpcRequest($method, $params);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
Tips: To get the UUID of the machine: $responseXml['data']['uuid_inventorymachine'][$key]. This also corresponds to the GLPI Machine ID prefixed by the UUID

  • Deploy a specific package on a target machine
$method = "msc.add_command_api";
$pid = "96982fce-hostname_vq918j7wtnwzm610by"; // pid - package_id
$target = "UUID1"; // target - machine_uuid

$params = [
    $pid,  // pid - package_id
    $target,  // target - machine_uuid
    array(  // params
    "name" => "devdemo-win-1",
    "hostname" => "devdemo-win-1",
    "uuid" => $target,
    "gid" => NULL,
    "from" => "base|computers|msctabs|tablogs",
    "pid" => $pid,
    // "title" => "DEPLOYMENT TITLE",
    "create_directory" => "on",
    "start_script" => "on",
    "clean_on_success" => "on",
    "do_reboot" => "",
    "do_wol" => "",
    "do_inventory" => "on",
    "next_connection_delay" => "60",
    "max_connection_attempt" => "3",
    "maxbw" => "0",
    "deployment_intervals" => "",
    "tab" => "tablaunch",
    "issue_halt_to" => array(),
    ),
    "push",  // mode
    NULL,  // gid
    array(),  // proxy 
    0  // cmd_type
];

    try {
        $responseXml = sendXmlRpcRequest($method, $params);

        $commandId = $responseXml; // Retrieve the command ID

        $method2 = "xmppmaster.addlogincommand";
        $params2 = [
            'root', // login
            $commandId, // commandid
            '', // grpid
            '', // nb_machine_in_grp
            '', // instructions_nb_machine_for_exec
            '', // instructions_datetime_for_exec
            '', // parameterspackage
            0, // rebootrequired
            0, // shutdownrequired
            0, // bandwidth
            0, // syncthing
            [] // params
        ];

        try {
    $responseXml2 = sendXmlRpcRequest($method2, $params2);

    } catch (Exception $e) {
        echo "Error: " . $e->getMessage();
    }

    } catch (Exception $e) {
        echo "Error: " . $e->getMessage();
}

  • Get deployment logs (Audit) from sessionname
$method = "xmppmaster.getlinelogssession";
$params = [
    "command63bb5ee8fc834eae89" // sessionname
];

try {
    $responseXml = sendXmlRpcRequest($method, $params);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
Tips: To get the deployment session name: $responseXml['tabdeploy']['sessionid'][$key]

  • Get all deployment logs by User and/or target
$method = "xmppmaster.get_deploy_by_user_with_interval";
$params = [
    "root",       // login_user
    "",           // state_deploy
    86400,        // intervalsearch
    0,            // start_pagination
    "20",         // end_pagination
    "spo-win-1",  // filt - hostname_machine
    "command"     // typedeploy
];

try {
    $responseXml = sendXmlRpcRequest($method, $params);
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}
