laravel-admin 上傳圖片過程中遇到的問題

1. 報錯 Disk [admin] not configured, please add a disk config in `config/filesystems.php`.

    在config/filesystem.php的disks項中添加如下內容：

'admin' => [
    'driver' => 'local',
    'root' => public_path('upload'),
    'visibility' => 'public',
    'url' => env('APP_URL').'/public/upload/',
],
2. Unable to guess the mime type as no guessers are available (Did you enable the php_fileinfo extension
原因是php沒有開啟php_fileinfo擴展，在php.ini中開啟擴展即可
3. 圖片上傳之后不顯示的問題
修改config/admin.php中的upload項，修改為：

'upload' => [

    // Disk in `config/filesystem.php`.
    'disk' => 'public',  //該項值原為admin,修改為public

    // Image and file upload path under the disk above.
    'directory' => [
        'image' => 'images',
        'file'  => 'files',
    ],
],
