Ftp.MakeDirectory嵌套结构 [英] Ftp.MakeDirectory nested structure

问题描述

如果你缺少在ftp上创建子目录的权限，你们会怎么做？
显然你不能在一个命令中创建一个目录

所以这个：

pre > path =ftp://someftp.com/files/newFolder/innerFolder;
var request =（FtpWebRequest）WebRequest.Create（path）;
request.Method = WebRequestMethods.Ftp.MakeDirectory;
var response =（FtpWebResponse）request.GetResponse（））;如果'files'或'newFolder'已经存在，


会抛出一个错误代码为550的异常。 p>

1. 如何检查我是否有权创建子目录？




2. 如果我没有这些权利，我该怎么办？

好吧：因为 FtpWebRequest 是无状态的 - 无法在FTP上更改当前目录。幸运的是，我们可以使用其中一个开源FTP库。这里有一个AlexPilotti的FTPS库的例子，它可以通过NuGet使用（var client = new FTPSClient（））$ b $来获得NuGet

  b {
 var address = Regex.Match（path，@^（ftp：//）？（\ w * |。？）* /）.Value.Replace（ftp：//， ）.Replace（/，）; 
 var dirs = Regex.Split（path.Replace（address，）.Replace（ftp：//，），/\").Where（x => x.Length> 0）; 
 client.Connect（address，credential，ESSLSupportMode.ClearText）; 
 foreach（var dir in dirs）
 {
 try 
 {
 client.MakeDir（dir）; 
} 
 catch（FTPException）
 {
} 
 client.SetCurrentDirectory（dir）; 
} 
 
} 
} 
  

What do you guys do if you lack of permissions to create subdirs on a ftp? Apparently you can't create a directory in one command

So this:

path = "ftp://someftp.com/files/newFolder/innerFolder";
var request = (FtpWebRequest)WebRequest.Create(path);
request.Method = WebRequestMethods.Ftp.MakeDirectory;
var response = (FtpWebResponse)request.GetResponse());

will throw an exception with error code 550 if 'files' or 'newFolder' is already exists

1. How can I check if I have the rights to create subdirs?

2. What can I do if I don't have those rights? Show me please code that lets you create a folder structure in more than one command.

解决方案

Alright: because FtpWebRequest is stateless - there is no way to change current directory on FTP. Fortunately we can use one of the open-source FTP libraries. Here's an example with AlexPilotti's FTPS library, which is availible through NuGet

using (var client = new FTPSClient())
{
     var address = Regex.Match(path, @"^(ftp://)?(\w*|.?)*/").Value.Replace("ftp://", "").Replace("/", "");
     var dirs = Regex.Split(path.Replace(address, "").Replace("ftp://", ""), "/").Where(x => x.Length > 0);
     client.Connect(address, credential, ESSLSupportMode.ClearText);
     foreach (var dir in dirs)
     {
        try
           {
              client.MakeDir(dir);
           }
        catch (FTPException)
        {
        }
        client.SetCurrentDirectory(dir);
     }

   }
}
