110.12. 步骤更改目录

在消耗文件（例如下载）或生成文件（如上传）时，Camel FTP 可以在两种模式下操作。

  • 步骤范围
  • 没有分步

您可以根据您的情况和安全问题来选择其中之一。某些 Camel 最终用户仅在使用步骤范围时下载文件，而其他用户只能下载文件（如果未通过）。您至少可选择（从 Camel 2.6 开始）。

在 Camel 2.0 - 2.5 中，只有一个模式，即：

  • 在 2.5 之前
  • 2.5 步骤范围

现在，您可以用来控制行为的 选择步骤 是 Camel 2.6。

请注意，在大多数情况下，目录的分步更改将只在用户限制于其主目录以及主目录被报告为 "/" 时起作用。

两者之间的差别最好通过示例进行说明。假设我们在远程 FTP 服务器中有以下目录结构，我们需要遍历和下载文件： 

/
/one
/one/two
/one/two/sub-a
/one/two/sub-b

并且每个子(a.txt)和子(b.txt)文件夹中都有一个文件。
