WinSCP .NET程序集 - 创建目录后如何设置文件夹权限？ [英] WinSCP .NET assembly - How to set folder permissions after creating directory?

问题描述

我正在构建一个网站，当用户注册时，我想要在SFTP服务器上创建一个目录，并在该目录中添加一个新文件。

我正在使用WinSCP .NET程序集，并编写C＃。

我注意到您只能在以下方法中设置权限： Session。 PutFiles
而不是在方法中： Session.CreateDirectory

Snd因此，在创建目录并将文件放入其中后，我无法访问该文件，因为我没有权限 - 我正在使用完整的URL访问该文件

如何访问文件？

PS。
当我手动更改目录权限时，我可以访问该文件。

解决方案

请注意这回答了您在创建目录时如何设置权限的问题。但是您的问题的根本原因是您的服务器集合的默认权限是错误的。服务器不应该使用默认的权限，这样您就无法访问刚刚创建的目录/文件！

目前无法直接设置权限，当创建目录或随后用WinSCP .NET程序集修改它们。

您可以通过以下方式将其删除：

• 创建一个本地空的临时目录


• 使用 Session.PutFiles ，在 TransferOptions.FilePermissions

  string directoryName =mydi R; 
 string directoryPath =/ home / username /+ directoryName; 
 string tempPath = Path.Combine（Path.GetTempPath（），directoryName）; 
 
 Directory.CreateDirectory（tempPath）; 
 
 try 
 {
 TransferOptions options = new TransferOptions（）; 
 options.FilePermissions = new FilePermissions {Octal =755}; 
 session.PutFiles（tempPath，directoryPath，false，options）.Check（）; 
} 
 finally 
 {
 Directory.Delete（tempPath）; 
} 
  

甚至可以创建一个空的临时目录。只要选择任何目录，例如目录，并使用文件掩码仅包含这一个目录，防止目录和子目录中的文件被上传。还可以使用目标路径中所需远程目录的显式名称，将已上传的目录重命名到所需的名称。

I'm building a web site and I want that when a user registers, to create a directory on the SFTP server and put in that directory a new file

I'm using WinSCP .NET assembly, and writing C#.

I noticed that you are able to set permissions only in the method: Session.PutFiles and not in the method: Session.CreateDirectory

Snd so after I create the directory and put the file in it, I cannot access the file because I don't have permissions - I'm accessing the file with the full URL

How can I access the file?

PS. When I change the directory permissions manually, I am able to access the file.

解决方案

Note that this answers your question how to set permissions when creating a directory. But a root cause of your problem is that a default permissions your server sets are wrong. The server should not use default permissions such that you cannot access a directory/file you have just created yourself!

It's currently not possible to directly set permissions, when a creating directory or modify them afterwards with WinSCP .NET assembly.
See https://winscp.net/tracker/show_bug.cgi?id=1075

You can hack it though as follows:

• Create a local empty temporary directory
• Upload it using the Session.PutFiles, setting permissions you need in TransferOptions.FilePermissions

string directoryName = "mydir";
string directoryPath = "/home/username/" + directoryName;
string tempPath = Path.Combine(Path.GetTempPath(), directoryName);

Directory.CreateDirectory(tempPath);

try
{
    TransferOptions options = new TransferOptions();
    options.FilePermissions = new FilePermissions { Octal = "755" };
    session.PutFiles(tempPath, directoryPath, false, options).Check();
}
finally
{
    Directory.Delete(tempPath);
}

You can even do without creating an empty temporary directory. Just pick any directory, e.g. directory of your account profile folder, and use a file mask to include only this one directory, preventing files in the directory and sub-directories from being uploaded. Also use an explicit name of desired remote directory in the target path to "rename" the uploaded directory to the name you want.
