使用SVN+C#.NET保持多台机器的文件同步
需求是有两个局域网(各有一台服务器,IP不固定),外网一台服务器(固定IP)
然后,三台服务器,都有一套相同的WEBFORM(WINFORM)程序运行 ,局域网内的机器,用户是有上传附件, 如何借助与外网的主机,保持这三台服务器的附件文件保持一致,局域网有可能出现长时间与外网服务器连不上的情况,两个局域网的两台服务器不能直接相连 (附件是不允许删除和修改,只有添加附件的功能) ;
迅速搭建SVN环境 请参考http://www.cnblogs.com/mouhong-lin/archive/2008/08/01/1258345.html
SVN的客户端"乌龟"支持命令行.于是想到了,使用C#中的文件监控类,监控到站点根目录下面的文件数据,如果有发生变化,那就通知SVN进行添加,然后再间隔固定的时候去提交或者更新.以便上传和下载数据.使用SVN的好处是,该软件支持原子操作,就是要么上传或下载,不用去考虑断点续传相关的程序.所以选择使用SVN而不使用FTP.
窗体控件添加如下图
相关代码如下:
private void button1_Click(object sender, EventArgs e)
{
try
{
if (string.IsNullOrEmpty(label2.Text.Trim())) { MessageBox.Show("请选择监控目录!"); return; } button1.Enabled = false; int x = Convert.ToInt32(textBox1.Text.Trim()); if (x < 5) { MessageBox.Show("请输入大于5的正整数!"); button1.Enabled = true ; return; } timer1.Interval = x *1000* 60;//10000; timer1.Enabled = true; button5.Enabled = true;
} catch { // MessageBox.Show("请输入正确的整数!"); button1.Enabled = true; timer1.Enabled =false ; }
} public static string Execute(string dosCommand, int outtime) { string output = ""; if (dosCommand != null && dosCommand != "") { Process process = new Process(); ProcessStartInfo startinfo = new ProcessStartInfo(); startinfo.FileName = "cmd.exe"; startinfo.Arguments = "/c" + dosCommand; startinfo.UseShellExecute = false; startinfo.RedirectStandardInput = false; startinfo.RedirectStandardOutput = true; startinfo.CreateNoWindow = true; process.StartInfo = startinfo; try { if (process.Start()) { if (outtime == 0) { process.WaitForExit(); } else { process.WaitForExit(outtime); } output = process.StandardOutput.ReadToEnd(); } } catch (Exception e) { throw e; } finally { if (process != null) { process.Close(); } } } MessageBox.Show(output); return output; } private void button2_Click(object sender, EventArgs e) { if (DialogResult.OK == folderBrowserDialog1.ShowDialog()) { label2.Text = folderBrowserDialog1.SelectedPath; } } private void fileSystemWatcher1_Changed(object sender, System.IO.FileSystemEventArgs e) { // MessageBox.Show("改变了" + e.ChangeType.ToString() + e.FullPath); try { ProcessStartInfo psi = new ProcessStartInfo("cmd"); psi.RedirectStandardOutput = true; psi.RedirectStandardInput = true; psi.UseShellExecute = false; Process p = Process.Start(psi); //改变命令行目录 p.StandardInput.WriteLine(@"chdir /d C:\Program Files\VisualSVN Server\bin"); //有新上传附件,则把新附件置为添加状态 p.StandardInput.WriteLine(@"svn add " + e.FullPath); p.StandardInput.WriteLine(@"exit"); p.WaitForExit(); p.Close(); } catch { } finally { } } private void button3_Click(object sender, EventArgs e) { if (string.IsNullOrEmpty(label2.Text.Trim())) { MessageBox.Show("请选择监控目录!"); return; } button2.Enabled = false; button3.Enabled = false; //要监视的目录 string sFolder = label2.Text; fileSystemWatcher1.EnableRaisingEvents = true; fileSystemWatcher1.Path = sFolder; fileSystemWatcher1.IncludeSubdirectories = true; fileSystemWatcher1.NotifyFilter = NotifyFilters.Size; label3.Text = "正在监视中
"; button4.Enabled = true; } private void button4_Click(object sender, EventArgs e) { //timer1.Enabled = false; fileSystemWatcher1.EnableRaisingEvents = false; button3.Enabled = true; button2.Enabled = true; label3.Text = "未开始监控"; } private void button5_Click(object sender, EventArgs e) { timer1.Enabled = false; button1.Enabled = true; } private void timer1_Tick(object sender, EventArgs e) { try { ProcessStartInfo psi = new ProcessStartInfo("cmd"); psi.RedirectStandardOutput = true; psi.RedirectStandardInput = true; psi.UseShellExecute = false; Process p = Process.Start(psi); p.StandardInput.WriteLine(@"chdir /d C:\Program Files\VisualSVN Server\bin"); p.StandardInput.WriteLine("svn commit -m \" "+System.DateTime.Now.ToString()+"\" " + label2.Text.Trim() );//提交(上传)目录下面的改变文件 p.StandardInput.WriteLine(@"exit"); p.WaitForExit(); p.Close(); label4.Text = "上次上传时间:" + System.DateTime.Now.ToString(); } catch { } finally { } } private void button6_Click(object sender, EventArgs e) { try { if (string.IsNullOrEmpty(label2.Text.Trim())) { MessageBox.Show("请选择监控目录!"); return; } button6.Enabled = false; int x = Convert.ToInt32(textBox2.Text.Trim()); if (x < 5) { MessageBox.Show("请输入大于5的正整数!"); button6.Enabled = true ; return; } timer2.Interval = x * 1000 * 60;//10000; timer2.Enabled = true; button7.Enabled = true; } catch { MessageBox.Show("请输入正确的整数!"); button7.Enabled = true; timer2.Enabled = false; } } private void button7_Click(object sender, EventArgs e) { timer2.Enabled = false; button6.Enabled = true; } private void timer2_Tick(object sender, EventArgs e) { try { ProcessStartInfo psi = new ProcessStartInfo("cmd"); psi.RedirectStandardOutput = true; psi.RedirectStandardInput = true; psi.UseShellExecute = false; Process p = Process.Start(psi); p.StandardInput.WriteLine(@"chdir /d C:\Program Files\VisualSVN Server\bin"); //更新(下载)服务器上的最新版本 p.StandardInput.WriteLine("svn update " + label2.Text.Trim()); p.StandardInput.WriteLine(@"exit"); p.WaitForExit(); p.Close(); label7.Text = "上次下载时间:" + System.DateTime.Now.ToString(); } catch { } finally { } } private void button8_Click(object sender, EventArgs e) { Application.Exit(); }
SVN命令行支持执行命令时发送用户名和密码.
相关的命令行参数如下 --username USER --password PASS .
