(C#) SCP Upload Contents of String to Remote FileDemonstrates how to upload the contents of a string variable using the SCP protocol (Secure Copy Protocol over SSH). The text is uploaded to a file in specific remote directory. If the file did not already exist, it is created. If it already existed, it is overwritten.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Ssh ssh = new Chilkat.Ssh(); // Connect to an SSH server: string hostname; int port; // Hostname may be an IP address or hostname: hostname = "www.some-ssh-server.com"; port = 22; bool success = ssh.Connect(hostname,port); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } // Wait a max of 5 seconds when reading responses.. ssh.IdleTimeoutMs = 5000; // Authenticate using login/password: success = ssh.AuthenticatePw("myLogin","myPassword"); if (success != true) { Debug.WriteLine(ssh.LastErrorText); return; } // Once 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; } string content = "This string will be the contents of the remote file."; string remotePath = "uploads/text/testUtf8.txt"; // The utf-8 byte representation of the string will be uploaded. // See https://www.chilkatsoft.com/p/p_463.asp for a list of valid charsets. string charset = "utf-8"; // This uploads to the "uploads/text" directory relative to the HOME // directory of the SSH user account. // Note: The remote target directory must already exist on the SSH server. success = scp.UploadString(remotePath,content,charset); if (success != true) { Debug.WriteLine(scp.LastErrorText); return; } remotePath = "uploads/text/testUtf8_withBOM.txt"; // To include the utf-8 preamble (also known as the BOM), // prefix the charset name with "bom:". Any charset that can // optionally include a BOM can be specified in this way. charset = "bom:utf-8"; // Uploads to a remote file that contains text in the // utf-8 representation, including the BOM at the start of the file. success = scp.UploadString(remotePath,content,charset); if (success != true) { Debug.WriteLine(scp.LastErrorText); return; } Debug.WriteLine("SCP upload string success."); // Disconnect ssh.Disconnect(); |
