C# 对接sftp（项目中用到）
在项目中用到的是获取文件列表和下载文件，这个是可以的，其他应该也没问题
在对接sftp时必须引用的三个dll文件，可以从newGet包管理里面下载
DiffieHellman
Org.Mentalis.Security
Tamir.SharpSSH
我们是做了一个exe用sqlserver的job进行调用的
//sftp信息 static string strFileName = ConfigurationSettings.AppSettings["FileUrl"]; static string SftpFilepath = ConfigurationSettings.AppSettings["SftpFilepath"]; static string ftpid = ConfigurationSettings.AppSettings["SftpServerIp"]; static string userName = ConfigurationSettings.AppSettings["SftpUserName"]; static string UserPwd = ConfigurationSettings.AppSettings["SftpUserPwd"]; static string conString = ConfigurationSettings.AppSettings["conString"]; static string DMTconString = ConfigurationSettings.AppSettings["DMTconString"]; //邮件用到 static SmtpContext context = new SmtpContext(); static string FromMial = ConfigHelper.GetConfigStr("FromMial");//发送方 static string ToMial = ConfigHelper.GetConfigStr("ToMial");//接收者 static string CCMial = ConfigHelper.GetConfigStr("CCMial");//抄送者 static string dir = AppDomain.CurrentDomain.BaseDirectory; static string SFTPfile = ConfigHelper.GetConfigStr("SFTPfile"); static void Main(string[] args) { context.Server = ConfigHelper.GetConfigStr("EmailServerAddress");//smtp地址 context.Port = ConfigHelper.GetConfigStr("EmailServerPort").CastToInt32();//端口号 context.UserName = ConfigHelper.GetConfigStr("UserName");//UserAccount context.Password = ConfigHelper.GetConfigStr("Password");//PWD SftpBll sftpBll = new SftpBll(); try { //文件列表 ArrayList FileList = sftpBll.FileList(conString, SftpFilepath); if (FileList.Count > 0) { //从sftp上下载文件 sftpBll.SFtpDownload(FileList, SftpFilepath, ftpid, userName, UserPwd); //将获取到的文件写入数据库 int n = sftpBll.AddFileRecord(conString, FileList, strFileName); } } catch (Exception ex) { } }
关于sftp的的bll做一些处理，调用helper
public class SftpBll { static string ftpid = ConfigHelper.GetConfigStr("SftpServerIp"); static string userName = ConfigHelper.GetConfigStr("SftpUserName"); static string UserPwd = ConfigHelper.GetConfigStr("SftpUserPwd"); static string FileUrl = ConfigHelper.GetConfigStr("FileUrl"); static string FileName = ConfigHelper.GetConfigStr("FileName"); clsSFTPHelper objSFtp = new clsSFTPHelper(ftpid, userName, UserPwd, 22); /// <summary> /// 从sftp上下载文件 /// </summary> /// <param name="strFileName"></param> /// <param name="SftpFilepath"></param> /// <param name="ftpid"></param> /// <param name="userName"></param> /// <param name="UserPwd"></param> /// <returns></returns> public void SFtpDownload(ArrayList FileList, string SftpFilepath, string ftpid, string userName, string UserPwd) { //SFtp IP:服务器的IP，UserName：登录名，PAW：密码 objSFtp.Connect(); if (objSFtp.Connected) { //获取文件列表 foreach (var item in FileList) { Log.CreateLogManager().Debug(SftpFilepath + "/" + item.ToString() + FileUrl); objSFtp.Get(SftpFilepath + "/" + item.ToString(), FileUrl); } } objSFtp.Disconnect(); } /// <summary> /// 移动文件 /// </summary> /// <param name="sourcePath"></param> /// <param name="destPath"></param> /// <returns></returns> public ArrayList MoveFile(string sourcePath, string destPath) { ArrayList existFile = new ArrayList(); destPath += DateTime.Now.ToString("yyyyMMddhhmmss"); if (Directory.Exists(sourcePath)) { if (!Directory.Exists(destPath)) { //目标目录不存在则创建 try { Directory.CreateDirectory(destPath); } catch (Exception ex) { throw new Exception("创建目标目录失败：" + ex.Message); } } //获得源文件下所有文件 List<string> files = new List<string>(Directory.GetFiles(sourcePath)); files.ForEach(c => { string destFile = Path.Combine(new string[] { destPath, Path.GetFileName(c) }); if (File.Exists(destFile)) { existFile.Add(destFile); } else { File.Move(c, destFile); } }); } return existFile; } } }
关于sftp的helper
public class clsSFTPHelper { private Session m_session; private Channel m_channel; private ChannelSftp m_sftp; //host:sftp地址 user：用户名 pwd：密码 public clsSFTPHelper(string server, string user, string pwd, int port) { JSch jsch = new JSch(); m_session = jsch.getSession(user, server, 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 (Exception ex) { throw ex; } } //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 (Exception ex) { throw ex; } } //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 (Exception ex) { Log.CreateLogManager().Debug(ex.Message); 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) { Console.WriteLine(message); } } }
