public function uploads(){
  $arr = array( "errorcode"=>"1","errormsg"=>"上傳成功!");
  $model = M('applicant');
  if (!empty($_FILES)) {
    //圖片上傳設置
    $config = array( 
    'maxSize' => 1000000, 
    'rootPath' => 'Public',
    'savePath' => '/Uploads/', 
    'saveName' => array('uniqid',''), 
    'exts'  => array('jpg', 'gif', 'png', 'jpeg'), 
    'autoSub' => false,

   $upload = new \Think\Upload($config);// 實例化上傳類
