REST through SSH Tunnel

See more REST Examples

Demonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls. Chilkat2 PHP

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

// Connect to an SSH server and establish the SSH tunnel:
try {

    // Authenticate with the SSH server via a login/password
    // or with a public key.
    // This example demonstrates SSH password authentication.
    $tunnel->SshAuthenticatePw('mySshLogin', 'mySshPassword');

    //  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.
