# Storage 保存文件

這邊只介紹FTP跟專案資料夾，關於如何架設FTP伺服器請點擊[傳送門](https://www.gitbook.com/book/judechih/integrated/edit#/edit/master/chapter1.md?_k=saxbhk)

## 設定

先做連接

```php
php artisan storage:link
```

其它設定都在`\config\filesystems.php`如下:

```php
<?php

return [

    'default' => 'ftp', // Supported: "local", "ftp", "s3", "rackspace"

    'cloud' => 'ftp', // 預設是'cloud' => 's3',

    'disks' => [

        'local' => [
            'driver' => 'local',
            'root' => storage_path('app'),
        ],

        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'visibility' => 'public',
        ],

        's3' => [
            'driver' => 's3',
            'key' => 'your-key',
            'secret' => 'your-secret',
            'region' => 'your-region',
            'bucket' => 'your-bucket',
        ],

        'ftp' => [ // 你所架設的FTP的設定在這邊
            'driver'   => 'ftp',
            'host' => '192.168.30.212',
            'username' => 'root',
            'password' => '12347890',
        ],

    ],

];
```

## 功能

```php
// 設置跟取得該文件的可見度
    Storage::setVisibility('new/jjde.txt','private');
    $val = Storage::getVisibility('new/jjde.txt');

// 取得該文件的內容
    $data = Storage::disk('public')->get('new/file6.txt'); // 還可以指定你要抓哪個資料夾得哪個disk的
    Storage::put('file.jpg', $data ); // 抓取到的內容，可以生成出另一個文件，可以移到你想要存放的disk的某個資料夾

// 查詢該文檔的字數
    $size = Storage::size('new/jjde.txt');

// 在文件的內容最前面輸入後面的字串
    Storage::prepend('new/file3.txt', 'Prepended Text');
    Storage::append('new/file3.txt', 'Prepended Text');

// 移動wtf里面的某個文件，到new資料夾里，並且給他一個名稱
    Storage::move('wtf/4e22ca05856c57fa31741cf11d40eb69.txt', 'new/file3.txt'); // 就像是剪下後貼到其他地方
    Storage::copy('old/file1.jpg', 'new/file1.jpg'); //就像是複製後貼到其他地方

// 複製某個文件，並且給他一個名稱，到new的資料夾
    Storage::putFileAs('new', new File('upload/text/1490771882_file.txt'), 'jjde.txt','private');

// 檢查文件是否存在
    $boolean = Storage::disk('ftp')->exists('new/file3.txt'); 

// 刪除指定文件
    Storage::delete('file.jpg'); // 可單一刪除
    Storage::delete(['file1.jpg', 'file2.jpg']); // 可複選刪除
```

還有很多其他的功能，這邊只列出我用過的，其他的請點擊這個[傳送門](http://d.laravel-china.org/docs/5.3/filesystem)
