php get url from dropbox

我正在使用推荐的php脚本dropboxhttps://github.com/BenTheDesigner，并且可以获得json响应，还可以列出文件。

ie这是我的开发者帐户中test.php.的文件输出

This is a list of all files in your [APP] Dropbox.
 api_upload_test.txt45 bytes
 dsdsdsdsdsdsd0 bytes
  ghhhhhhhhhhhh0 bytes
If I Fell - The Beatles.mp31 MB
 Koala.jpg762.5 KB
 test_download_api_upload_test.txt45 bytes

但我需要这些文件的绝对url。iehttp://something/ssandbox/folder/Koala.jpg

或http://something/fileget/http://somewing/koala.jpg

我找不到任何关于指定url或是否使用dropbox url的信息。可能是一个愚蠢而简单的答案。

This is an example of the array;
    array(3) {
       ["code"]=>
      string(3) "200"
      ["body"]=>
     object(stdClass)#8 (9) {
        ["hash"]=>
    string(32) "df98863d80aa0c89f5e359a4f3e10b5a"
    ["thumb_exists"]=>
    bool(false)
    ["bytes"]=>
    int(0)
    ["path"]=>
    string(1) "/"
    ["is_dir"]=>
    bool(true)
    ["size"]=>
    string(7) "0 bytes"
