我想返回带有数据的图像。
$ads = DB::table('ads')->whereRaw('category_id=' .$id)->orderBy('id', 'desc')->get();
$filename = public_path().'/uploads/images/'.$ads->ad_image;
$filename = (file_get_contents($filename));
$image = Array('image'=>json_encode(base64_encode($filename)));
$ads[0]->image = $image;
return $ads;
