Ganymed SSH-2 for Java Series 8 Sftpv3client Description:

Sftpv3client is a SFTP (Protocol version 3) of SSH for Java, and the client implements the Java class through a simple synchronization of the SSH-2 connection.

Its basic external methods are as follows:

Public sftpv3fileattributes Stat (String path) throws IOException;

--Retrieves the file properties of the file.

Returns the Sftpv3fileattributes object, which is mentioned in an article before this object, mainly to record directories, permissions, and other information;

	
	Public sftpv3fileattributes Stat (String path) throws IOException
	{return
		statboth (path, Packet.ssh_fxp_stat) ;
	}

Public sftpv3fileattributes Lstat (String path) throws IOException

--Retrieves the file properties of the file. This method does not follow symbolic links on the server.

	Public sftpv3fileattributes Lstat (String path) throws IOException
	{return
		statboth (path, packet.ssh_fxp_ LSTAT);
	}

Public Vector ls (String dirname) throws IOException

--"lists the contents of a directory."

This is demonstrated when you delete a non-empty directory, as it does with the Linux environment LS display information, and can not be presented recursively.

Public Vector ls (String dirname) throws IOException
	{
		byte[] handle = Opendirectory (dirname);
		Vector result = Scandirectory (handle);
		CloseHandle (handle);
		return result;
	}

public void mkdir (String dirname, int posixpermissions) throws IOException

--"Create a new directory

The first parameter is the directory path, and the second is the permission code: for example, 0600 represents RW's specific reference to Linux permissions.

public void mkdir (String dirname, int posixpermissions) throws IOException
	{
		int req_id = Generatenextrequestid ( );

		Typeswriter tw = new Typeswriter ();
		Tw.writestring (dirname, charsetname);
		Tw.writeuint32 (attribflags.ssh_filexfer_attr_permissions);
		Tw.writeuint32 (posixpermissions);

		SendMessage (Packet.ssh_fxp_mkdir, req_id, Tw.getbytes ());

		Expectstatusokmessage (req_id);
	}

public void rm (String fileName) throws IOException
--"Delete a file

preceded by a demo;

	public void rm (String fileName) throws IOException
	{
		int req_id = Generatenextrequestid ();

		Typeswriter tw = new Typeswriter ();
		Tw.writestring (FileName, charsetname);

		SendMessage (Packet.ssh_fxp_remove, req_id, Tw.getbytes ());

		Expectstatusokmessage (req_id);
	}

public void RmDir (String dirname) throws IOException

--"Delete an empty directory

Before there is a demo, also implements a how to delete a non-empty directory;

public void RmDir (String dirname) throws IOException
	{
		int req_id = Generatenextrequestid ();

		Typeswriter tw = new Typeswriter ();
		Tw.writestring (dirname, charsetname);

		SendMessage (Packet.ssh_fxp_rmdir, req_id, Tw.getbytes ());

		Expectstatusokmessage (req_id);
	}

public void mv (string oldpath, String NewPath) throws IOException

--"Move a file or directory

public void mv (string oldpath, String newpath) throws IOException
	{
		int req_id = Generatenextrequestid ();

		Typeswriter tw = new Typeswriter ();
		Tw.writestring (OldPath, charsetname);
		Tw.writestring (NewPath, charsetname);

		SendMessage (Packet.ssh_fxp_rename, req_id, Tw.getbytes ());

		Expectstatusokmessage (req_id);
	}

Public Sftpv3filehandle Openfilero (String fileName) throws IOException

--"Open a file to read content;"

	Public Sftpv3filehandle Openfilero (String filename) throws IOException
	{return
		openfile (filename, 0x00000001, NULL); Ssh_fxf_read	
	}

Let's keep looking: Sftpv3filehandle

public class Sftpv3filehandle
{
	final sftpv3client client;
	Final byte[] FileHandle;
	Boolean isclosed = false;

	/* The constructor isn't public

	/sftpv3filehandle (sftpv3client client, byte[] h)
	{
		this.client = client;
  this.filehandle = h;
	}

	/**
	 * Get the Sftpv3client instance which created this handle. 
	 * 
	 * @return A sftpv3client instance.
	 * * Public
	sftpv3client getclient ()
	{return
		client;
	}

	/**
	 * Check If this handle is closed with the {@link sftpv3client#closefile (Sftpv3filehandle)} method
	 * of the <code>SFTPv3Client</code> instance which created the handle.
	 * 
	 * @return If the handle is closed.
	 *
	/public boolean isclosed ()
	{return
		isclosed;
	}

The content is read in binary notation byte[];

Public Sftpv3filehandle openfilerw (String fileName) throws IOException

--"Open the file to read and write operations;"

	Public Sftpv3filehandle openfilerw (String filename) throws IOException
	{return
		openfile (FileName, 0x00000003 , null); Ssh_fxf_read | Ssh_fxf_write
	}

Public Sftpv3filehandle CreateFile (String fileName) throws IOException

--"Create a file for read and write operations

	Public Sftpv3filehandle CreateFile (String filename) throws IOException
	{return
		CreateFile (fileName, null);
	

Public Sftpv3filehandle CreateFile (String fileName, Sftpv3fileattributes attr) throws IOException

--"Create a file to open it and read and write

Sftpv3fileattributes permissions and other settings objects;

	Public Sftpv3filehandle CreateFile (String fileName, Sftpv3fileattributes attr) throws IOException
	{
		return OpenFile (fileName, 0x00000008 | 0x00000003, attr); Ssh_fxf_creat | Ssh_fxf_read | Ssh_fxf_write
	}

Public Sftpv3filehandle createfiletruncate (String fileName) throws IOException

--"Create a file (if it already exists, truncate), open it and read and write

	Public Sftpv3filehandle createfiletruncate (String fileName) throws IOException
	{return
		createfiletruncate ( FileName, null);
	

Public Sftpv3filehandle createfiletruncate (String fileName, Sftpv3fileattributes attr) throws IOException

--"Create a file (if it already exists, truncate), open it and read the append write operation;"

Public Sftpv3filehandle createfiletruncate (String fileName, Sftpv3fileattributes attr) throws IOException
{
Return OpenFile (fileName, 0x00000018 | 0x00000003, attr); Ssh_fxf_creat | Ssh_fxf_trunc | Ssh_fxf_read | Ssh_fxf_write
}

Use:

Incoming conn Parameters:

	Connection conn = null;

		try {
			conn = getopenedconnection (host, username, password, port);

			Sftpv3client sftpclient = new sftpv3client (conn);

Finally, you need to close the session connection:

	Sftpclient.close ();

Conn. close ();

The rest of the way everyone can see for themselves;
