(PHP ActiveX) REST through SSH Tunnel

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Socket')
$tunnel = new COM("Chilkat.Socket");

$sshHostname = 'sftp.example.com';
$sshPort = 22;

// Connect to an SSH server and establish the SSH tunnel:
$success = $tunnel->SshOpenTunnel($sshHostname,$sshPort);
if ($success != 1) {
    print $tunnel->LastErrorText . "\n";
    exit;
}

// Authenticate with the SSH server via a login/password
// or with a public key.
// This example demonstrates SSH password authentication.
$success = $tunnel->SshAuthenticatePw('mySshLogin','mySshPassword');
if ($success != 1) {
    print $tunnel->LastErrorText . "\n";
    exit;
}

//  OK, the SSH tunnel is setup.  Now open a channel within the tunnel.
//  (Any number of channels may be created from the same SSH tunnel.
//  Multiple channels may coexist at the same time.)

// This example connects to a REST server through the SSH tunnel.
// It will connect to the Amazon AWS service for this example.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest')
$rest = new COM("Chilkat.Rest");

$bTls = 1;
$port = 443;
$maxWaitMs = 5000;

// This returns a socket object that is a single channel within the SSH tunnel.
// channel is a Chilkat.Socket
$channel = $tunnel->SshOpenChannel('s3.amazonaws.com',$port,$bTls,$maxWaitMs);
if ($tunnel->LastMethodSuccess != 1) {
    print $tunnel->LastErrorText . "\n";
    exit;
}

// Use the connection.  (This connection is a TLS running on an SSH channel through an SSH tunnel.
// In other words, TLS is wrapped within the SSH tunnel.)
$success = $rest->UseConnection($channel,1);
if ($success != 1) {
    print $rest->LastErrorText . "\n";

    exit;
}

// Provide AWS credentials for the REST call.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.AuthAws')
$authAws = new COM("Chilkat.AuthAws");
$authAws->AccessKey = 'AWS_ACCESS_KEY';
$authAws->SecretKey = 'AWS_SECRET_KEY';
$authAws->ServiceName = 's3';

// List all buckets for the account...
$responseXml = $rest->fullRequestNoBody('GET','/');
if ($rest->LastMethodSuccess != 1) {
    print $rest->LastErrorText . "\n";

    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml')
$xml = new COM("Chilkat.Xml");
$success = $xml->LoadXml($responseXml);

// Show the full XML returned.
print $xml->getXml() . "\n";

// Iterate over the buckets, showing each bucket name.
$success = $xml->FindChild2('Buckets');
if ($xml->FirstChild2() == 1) {
    print $xml->getChildContent('Name') . "\n";
    while (($xml->NextSibling2() == 1)) {
        print $xml->getChildContent('Name') . "\n";
    }

}

// Move the internal pointer back to the root node.
$xml->GetRoot2();
