Apache Mina SSHD - FileZilla顯示錯誤的目錄結構

我使用Apache Mina SSHD將SSH服務器設置爲SFTP服務器。我實現了我自己的FileSystemFactory，以便爲登錄的用戶創建特定的目錄。使用FileZilla打開與服務器的連接時，目錄結構顯示爲錯誤。Apache Mina SSHD - FileZilla顯示錯誤的目錄結構

在根目錄視圖，顯示一個空文件夾。這個不存在。應該只有兩個目錄。「上傳」和「下載」。

當我打開上傳目錄，我再次看到它不應該被顯示，因爲它不存在的空目錄。此外，顯示另一個上傳目錄。我無法打開它，因爲它說/上傳/上傳不存在，這是真的，但我不明白它爲什麼顯示。

當我連接到WinSCP時，我沒有得到這個顯示錯誤。有誰知道它爲什麼會發生或如何解決它？

編輯：

FileSystemFactory實現：

public class CustomFileSystemFactory implements FileSystemFactory { 
    private String defaultHomeDir; 
    private FileSystem fileSystem; 

    public CustomFileSystemFactory(String defaultHomeDir){ 
    this.defaultHomeDir = defaultHomeDir; 
    } 

    public String getDefaultHome(){ 
    return defaultHomeDir; 
    } 

    public FileSystem getFileSystem(){ 
    return fileSystem; 
    } 

    @Override 
    public FileSystem createFileSystem(Session session) throws IOException { 
    Path dir = computeRootDir(session.getUsername()); 
    if (dir == null) { 
     throw new InvalidPathException(session.getUsername(), "Cannot resolve home directory"); 
    } 

    if(!Files.exists(dir)){ 
     Files.createDirectory(dir); 
    } 
    setupFolders(session.getUsername()); 
    FileSystem fileSystem = new RootedFileSystemProvider().newFileSystem(dir, Collections.emptyMap()); 
    return fileSystem; 
    } 

    protected Path computeRootDir(String username){ 
    Path path = Paths.get(defaultHomeDir + Utils.getPrincipalExtId(username) + "/"); 
    return path; 
    } 

    protected void setupFolders(String username) throws IOException { 
    Path homeDir = computeRootDir(username); 
    File uploadFolder = new File(homeDir + "/upload/"); 
    File downloadFolder = new File(homeDir + "/download/"); 
    if(!uploadFolder.exists()){ 
     uploadFolder.mkdirs(); 
    } 
    if(!downloadFolder.exists()){ 
     downloadFolder.mkdirs(); 
    } 
    } 
}

向我們展示來自WinSCP和FileZilla（真正的日誌文件，而不是來自GUI的消息日誌）的會話日誌文件。 –

我添加了兩個日誌文件。希望你想看到什麼？ – nlsn

對不起，我沒有意識到它是SFTP，所以列表不會在普通日誌中看到。你可以從WinSCP添加「Debug 2」級別的日誌嗎？同時向我們顯示您的文件系統代碼。 –

的問題是Apache的米納SSHD解決1.1.0，參見

保持了早期版本的解決方案：

的問題是部分兩側，米娜SSHD服務器和客戶端的FileZilla。

在SFTP版本3（即FileZilla使用）中，每個文件的條目都包含結構化元數據和僅顯示字符串（又名longname字段），格式與* nix ls -l命令中的格式相似。該顯示字符串不應該被解析。

但FileZilla解析它，而不是使用結構化元數據（文件時間戳除外）。該FileZilla中用來實現SFTP協議內部psftp過程僅提供該信息給父FileZilla中處理（sftp_cmd_ls功能）：

if (ournames[i]->attrs.flags & SSH_FILEXFER_ATTR_ACMODTIME) { 
    mtime = ournames[i]->attrs.mtime; 
} 
fzprintf(sftpListentry, "%lu %s", mtime, ournames[i]->longname);

的米娜SSHD/SFTP（所述SftpSubsystem類），列出當.和..元目錄錯誤地在僅顯示字符串中使用當前文件夾名稱和父文件夾名稱，而不是.和..。它正確使用結構化數據中的.和..（shortname字段）。

FileZilla從列表中讀取錯誤的名稱並且感到困惑，將條目視爲實際的子目錄條目而不是元目錄。

在根目錄中，.和..可能都列爲/。 FileZilla修剪一切，直到最後的/，導致空條目（並且兩個相同名稱的[空名]條目可能合併成一條）。

所以不是

. 
.. 
upload 
download

的FileZilla中看到

/ [treated as an empty string] 
/[treated as an empty string and ignored as duplicate] 
upload 
download

在upload目錄，.被列爲upload和..爲/（導致空條目）。

所以不是

. 
..

的FileZilla中看到

upload 
/[treated as an empty string]

的WinSCP，相反，從不使用唯一的顯示字符串解析文件/目錄名。主要是（如果服務器支持的話，Mina SSHD所做的）使用SFTP版本4，它甚至不包括僅顯示字符串。

爲了解決這個問題，就需要通過SftpSubsystem.writeDirEntry方法的shortName參數來調用的方法.getLongName。並修改.getLongName以使用shortName它返回的字符串而不是getShortName(f)。

請參閱下面的修改後的代碼SftpSubsystem以及描述更改的註釋。該代碼是從米娜SSHD版本1.0

protected void writeDirEntry(int id, DirectoryHandle dir, Buffer buffer, int index, Path f, String shortName, LinkOption... options) throws IOException { 
    ... 
    if (version == SFTP_V3) { 
     // added shortName argument 
     String longName = getLongName(f, options, shortName); 
    } else { 
    ... 
} 

// added shortName parameter 
protected String getLongName(Path f, LinkOption... options, String shortName) throws IOException { 
    // added shortName argument 
    return getLongName(f, true, options, shortName); 
} 

// added shortName parameter 
private String getLongName(Path f, boolean sendAttrs, LinkOption... options, String shortName) throws IOException { 
    ... 
    // added shortName argument 
    return getLongName(f, attributes, shortName); 
} 

// added shortName parameter 
private String getLongName(Path f, Map<String, ?> attributes, String shortName) throws IOException { 
    ... 
    return (SftpHelper.getBool(isDirectory) ? "d" : (SftpHelper.getBool(isLink) ? "l" : "-")) 
      + PosixFilePermissions.toString(perms) + " " 
      + (attributes.containsKey("nlink") ? attributes.get("nlink") : "1") 
      + " " + username + " " + group + " " + lengthString + " " 
      + UnixDateFormat.getUnixDate((FileTime) attributes.get("lastModifiedTime")) 
      // using shortName instead of getShortName(f) 
      + " " + shortName; 
} 

// + you need to modify sendPath to pass getShortName(f) 
// to its call to getLongName

我不做Java，所以請原諒任何斷碼。

考慮將錯誤報告給Mina SSHD項目。如果需要，請將問題鏈接到此處。

感謝您的時間。這似乎解決了。 :)我也向Apache Mina SSHD項目報告了這一點。 https://issues.apache.org/jira/browse/SSHD-622 – nlsn
