(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 <CkSocket.h> #include <CkRest.h> #include <CkAuthAws.h> #include <CkXml.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. CkSocket tunnel; const char *sshHostname = "sftp.example.com"; int sshPort = 22; // Connect to an SSH server and establish the SSH tunnel: success = tunnel.SshOpenTunnel(sshHostname,sshPort); if (success == false) { std::cout << tunnel.lastErrorText() << "\r\n"; return; } // 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 == false) { std::cout << tunnel.lastErrorText() << "\r\n"; 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. CkRest rest; bool bTls = true; int port = 443; int maxWaitMs = 5000; // This returns a socket object that is a single channel within the SSH tunnel. CkSocket channel; success = tunnel.SshNewChannel("s3.amazonaws.com",port,bTls,maxWaitMs,channel); if (success == false) { std::cout << tunnel.lastErrorText() << "\r\n"; 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) { std::cout << rest.lastErrorText() << "\r\n"; return; } // Provide AWS credentials for the REST call. CkAuthAws authAws; authAws.put_AccessKey("AWS_ACCESS_KEY"); authAws.put_SecretKey("AWS_SECRET_KEY"); authAws.put_ServiceName("s3"); success = rest.SetAuthAws(authAws); // List all buckets for the account... const char *responseXml = rest.fullRequestNoBody("GET","/"); if (rest.get_LastMethodSuccess() != true) { std::cout << rest.lastErrorText() << "\r\n"; return; } CkXml xml; success = xml.LoadXml(responseXml); // Show the full XML returned. std::cout << xml.getXml() << "\r\n"; // Iterate over the buckets, showing each bucket name. success = xml.FindChild2("Buckets"); if (xml.FirstChild2() == true) { std::cout << xml.getChildContent("Name") << "\r\n"; while ((xml.NextSibling2() == true)) { std::cout << xml.getChildContent("Name") << "\r\n"; } } // Move the internal pointer back to the root node. xml.GetRoot2(); } |
