ruby-on-rails - Ruby: Net::SFTP 获取文件路径

Question

当我们使用 sftp.dir.entries 方法时，我们如何获取响应的文件完整路径？

我想要一个目录的文件内容(递归)。我使用 sftp.dir.entries 方法来列出存在的文件。我该如何获取内容？

也许您正在寻找 glob method :

Works as ::Dir.glob, matching (possibly recursively) all directory entries under path against pattern. If a block is given, matches will be yielded to the block as they are found; otherwise, they will be returned in an array when the method finishes.

Because working over an SFTP connection is always going to be slower than working purely locally, don't expect this method to perform with the same level of alacrity that ::Dir.glob does; it will work best for shallow directory hierarchies with relatively few directories, though it should be able to handle modest numbers of files in each directory.

因此，例如(也取自文档):

sftp.dir.glob("/remote/path", "**/*.rb")

应该返回远程机器上任何目录级别的所有 *.rb 文件。要获取所有文件，请改用"**/*"。另见 Dir class' glob method .
