PHP file download returns page not found

steve_lae0901

using cURL in PHP to call the /files/download api.  Dropbox returns "Error (4xx) We can't find the page you're looking for."  How to troubleshoot? I think I am using the API correctly.

 

function getTextFile( $token )
{
  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, "https://content.dropboxapi.com/2/files/download");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0 ) ;

  $headers = array();
  $headers[] = "Authorization: Bearer " . $token ;
  $headers[] = "Dropbox-Api-Arg: {\"path\": \"/test_upload.txt\"}";
  $headers[] = 'Content-Type: text/plain; charset=utf-8' ;
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

  $result = curl_exec($ch);
  if (curl_errno($ch)) {
      echo 'Error:' . curl_error($ch);
  }
  curl_close ($ch);
  return $result ;
}

I don't see anything clearly wrong here. (We recommend not disabling SSL verification though.)

Anyway, it's possible to get that generic 4xx error if the HTTP request itself is malformed. For example, perhaps $token is leaking an invalid value into the Authorization header. Can you check that it is the access token string only?
