本文主要是C#调用SSH实现文件上传下载功能,主要是要引用第三方类库Tamir.SharpSSH.dll。
以下是SFTPHelper类,实现了对文件的操作,可供参考。
public class SFTPHelper { private Session m_session; private Channel m_channel; private ChannelSftp m_sftp; //host:sftp地址 user:用户名 pwd:密码 public SFTPHelper(string host, string user, string pwd) { string[] arr = host.Split(‘:‘); string ip = arr[0]; int port = 22; if (arr.Length > 1) port = Int32.Parse(arr[1]); JSch jsch = new JSch(); m_session = jsch.getSession(user, ip, port); MyUserInfo ui = new MyUserInfo(); ui.setPassword(pwd); m_session.setUserInfo(ui); } //SFTP连接状态 public bool Connected { get { return m_session.isConnected(); } } //连接SFTP public bool Connect() { try { if (!Connected) { m_session.connect(); m_channel = m_session.openChannel("sftp"); m_channel.connect(); m_sftp = (ChannelSftp)m_channel; } return true; } catch { return false; } } //断开SFTP public void Disconnect() { if (Connected) { m_channel.disconnect(); m_session.disconnect(); } } //SFTP存放文件 public bool Put(string localPath, string remotePath) { try { Tamir.SharpSsh.java.String src = new Tamir.SharpSsh.java.String(localPath); Tamir.SharpSsh.java.String dst = new Tamir.SharpSsh.java.String(remotePath); m_sftp.put(src, dst); return true; } catch { return false; } } //SFTP获取文件 public bool Get(string remotePath, string localPath) { try { Tamir.SharpSsh.java.String src = new Tamir.SharpSsh.java.String(remotePath); Tamir.SharpSsh.java.String dst = new Tamir.SharpSsh.java.String(localPath); m_sftp.get(src, dst); return true; } catch { return false; } } //删除SFTP文件 public bool Delete(string remoteFile) { try { m_sftp.rm(remoteFile); return true; } catch { return false; } } //获取SFTP文件列表 public ArrayList GetFileList(string remotePath, string fileType) { try { Tamir.SharpSsh.java.util.Vector vvv = m_sftp.ls(remotePath); ArrayList objList = new ArrayList(); foreach (Tamir.SharpSsh.jsch.ChannelSftp.LsEntry qqq in vvv) { string sss = qqq.getFilename(); if (sss.Length > (fileType.Length + 1) && fileType == sss.Substring(sss.Length - fileType.Length)) { objList.Add(sss); } else { continue; } } return objList; } catch { return null; } } //登录验证信息 public class MyUserInfo : UserInfo { String passwd; public String getPassword() { return passwd; } public void setPassword(String passwd) { this.passwd = passwd; } public String getPassphrase() { return null; } public bool promptPassphrase(String message) { return true; } public bool promptPassword(String message) { return true; } public bool promptYesNo(String message) { return true; } public void showMessage(String message) { } }
以下是调用方式:
SFTPHelper sftp = new SFTPHelper("10.168.38.72", "root", "root");
sftp.Connect();
sftp.Get("\\a.txt", "E:\\");
sftp.Disconnect();
