Java SFTP（apache vfs2） - 密码@

Question

我尝试使用org.apache.commons.vfs2通过SFTP下载文件。 问题是，密码包含＆＃39; @＆＃39; char，所以这会导致URI被错误地解析：

org.apache.commons.vfs2.FileSystemException: Expecting / to follow the hostname in URI

有没有人知道如何解决这个问题？ （显然，我无法更改密码）。这是我使用的代码：

String sftpUri = "sftp://" + userName + ":" + password + "@"
        + remoteServerAddress + "/" + remoteDirectory + fileName;

String filepath = localDirectory + fileName;
File file = new File(filepath);
FileObject localFile = manager.resolveFile(file.getAbsolutePath());

FileObject remoteFile = manager.resolveFile(sftpUri, opts);
localFile.copyFrom(remoteFile, Selectors.SELECT_SELF);

Answer 1

使用an actual URI constructor而不是自己动手：

String userInfo = userName + ":" + password;
String path = remoteDirectory + filename;  // Need a '/' between them?
URI sftpUri = new URI("sftp", userInfo, remoteServerAddress, -1, path, null, null);
...
FileObject remoteFile = manager.resolveFile(sftpUri.toString(), opts);
