(.NET Core C#) Setting Environment Variables for SCP TransfersDemonstrates how to set remote environment variables for an SCP transfer. Note 1: This example requires Chilkat v9.5.0.79 or greater. Note 2: Setting environment variables for SCP is only supported by some SSH servers.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Ssh ssh = new Chilkat.Ssh(); // First connect to an SSH server. bool success = ssh.Connect("example.com",22); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } // Wait a max of 5 seconds when reading responses.. ssh.IdleTimeoutMs = 5000; // Authenticate.. success = ssh.AuthenticatePw("myLogin","myPassword"); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } // After the SSH object is connected and authenticated, we use it // as the underlying transport in our SCP object. Chilkat.Scp scp = new Chilkat.Scp(); success = scp.UseSsh(ssh); if (success != true) { Debug.WriteLine(scp.LastErrorText); return; } // Specify the environment variables to be set in JSON as follows. // This example sets two environment variables. One is named "LCS_PASSWORD" and the other "MY_TEST_NAME". Chilkat.JsonObject jsonEnvVars = new Chilkat.JsonObject(); jsonEnvVars.EmitCompact = false; jsonEnvVars.UpdateString("LCS_PASSWORD","secret"); jsonEnvVars.UpdateString("MY_TEST_NAME","abc"); string strEnvVars = jsonEnvVars.Emit(); Debug.WriteLine(strEnvVars); // Setting the SendEnv property causes Chilkat to set each environment variable on the SSH server // prior to doing the upload or download. scp.SendEnv = strEnvVars; // Do the upload.. string remotePath = "starfish.jpg"; string localPath = "qa_data/jpg/starfish.jpg"; success = scp.UploadFile(localPath,remotePath); if (success != true) { Debug.WriteLine(scp.LastErrorText); return; } Debug.WriteLine("SCP upload file success."); // Disconnect ssh.Disconnect(); |
