(Unicode C++) REST through SSH TunnelDemonstrates how to connect through an SSH Tunnel (via port-forwarding) to make REST API calls. Note: This example requires Chilkat v11.0.0 or greater.
#include <CkSocketW.h> #include <CkRestW.h> #include <CkAuthAwsW.h> #include <CkXmlW.h> void ChilkatSample(void) { bool success = false; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. CkSocketW tunnel; const wchar_t *sshHostname = L"sftp.example.com"; int sshPort = 22; // Connect to an SSH server and establish the SSH tunnel: success = tunnel.SshOpenTunnel(sshHostname,sshPort); if (success == false) { wprintf(L"%s\n",tunnel.lastErrorText()); return; } // Authenticate with the SSH server via a login/password // or with a public key. // This example demonstrates SSH password authentication. success = tunnel.SshAuthenticatePw(L"mySshLogin",L"mySshPassword"); if (success == false) { wprintf(L"%s\n",tunnel.lastErrorText()); return; } // 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. CkRestW rest; bool bTls = true; int port = 443; int maxWaitMs = 5000; // This returns a socket object that is a single channel within the SSH tunnel. CkSocketW channel; success = tunnel.SshNewChannel(L"s3.amazonaws.com",port,bTls,maxWaitMs,channel); if (success == false) { wprintf(L"%s\n",tunnel.lastErrorText()); return; } // 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,true); if (success != true) { wprintf(L"%s\n",rest.lastErrorText()); return; } // Provide AWS credentials for the REST call.
