Java SFTP (apache vfs2) - 密码@ [英] Java SFTP (apache vfs2) - password with @

问题描述

我正在尝试使用 org.apache.commons.vfs2 通过 SFTP 下载文件.问题是，密码包含@"字符，因此这会导致 URI 解析不正确:

I'm trying to use the org.apache.commons.vfs2 to download a file via SFTP. The problem is, the password contains the '@' char, so this causes the URI to be parsed incorrectly:

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

有人知道如何解决这个问题吗?(显然，我无法更改密码).这是我正在使用的代码:

Does anyone has an idea how to get around this issue? (I can't change the password, obviously). This is the code I'm using:

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);

推荐答案

使用 实际的 URI 构造器 而不是手动滚动您自己的:

Use an actual URI constructor instead of hand-rolling your own:

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);
