Laravel Storage 的常见用法

内容写入磁盘文件

> php artisan tinker
>>> use Illuminate\Support\Facades\Storage;
>>> Storage::put('test.txt', 'hello');
=> true

ls storage/app/
public/  test.txt

文件默认创建在 /storage/app 目录下

获取文件存储的本地磁盘全路径

继续在 tinker 中测试一下

>>> storage_path()
=> "/home/zhongwei/work/my_project/storage"
>>> storage_path('test.txt')
=> "/home/zhongwei/work/my_project/storage/test.txt"
>>> storage_path('app/test.txt')
=> "/home/zhongwei/work/my_project/storage/app/test.txt"

可见，应该是 storage_path('app/test.txt')

删除文件

>>> Storage::delete('test.txt')
=> true

文件默认存储路径是在哪里设置的

Config/filesystems.php

    'disks' => [

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

        'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ],

Local.root 指定的即是默认路径。

判断一个文件是否存在

>>> Storage::put('public/test.txt', 'hello');
=> true
>>> Storage::exists('public/test.txt');
=> true
>>> Storage::exists('public/test1.txt');
=> false
