我想列出我的Scala Play Framework 2应用程序public/images目录中的所有文件名，以便Play应用程序仅将这些文件名列出到HTML页面.该怎么办?

I want to list out all the file names in the public/images directory for my Scala Play Framework 2 application so that the Play Application just lists those file names to the HTML page. How can this be done?

Is there a right way to access the public/images directory to read files or list the directory? I don't want to use absolute directory paths.

推荐答案

在

There is method getFile(relateivePath: String): File on Play object and also in the Application class which returns file relative to application root directory. In your case:

Play.getFile("public/images")

返回 File 对象，代表public/images/目录.您可以调用list或listFiles来获取目录的内容.

return File object, which represent public/images/directory. You can call list or listFiles on it to get contents of the directory.
