我正在尝试通过以下方式检查文件是否已存在于存储中

if(Storage::exists($request->file_name)):
    dd(var_dump("it did exist"));
else:
    dd(var_dump("it did not exist"));
endif

但它总是返回一个字符串“它确实存在”，即使文件被实际删除或文件不存在，任何想法，帮助？

我确定我的存储位置设置没有问题，因为我在将文件上传到存储时没有问题，

Storage::put($file_name, File::get($file));

PS：我在 Laravel 5.0

更新：

这是我的 Laravel 5.0 配置文件夹中的 filesystems.php

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Default Filesystem Disk
    |--------------------------------------------------------------------------
    |
    | Here you may specify the default filesystem disk that should be used
    | by the framework. A "local" driver, as well as a variety of cloud
    | based drivers are available for your choosing. Just store away!
    |
    | Supported: "local", "s3", "rackspace"
    |
    */

    'default' => 'local',

    /*
    |--------------------------------------------------------------------------
    | Default Cloud Filesystem Disk
    |--------------------------------------------------------------------------
    |
    | Many applications store files both locally and in the cloud. For this
    | reason, you may specify a default "cloud" driver here. This driver
    | will be bound as the Cloud disk implementation in the container.
    |
    */

    'cloud' => 's3',

    /*
    |--------------------------------------------------------------------------
    | Filesystem Disks
    |--------------------------------------------------------------------------
    |
    | Here you may configure as many filesystem "disks" as you wish, and you
    | may even configure multiple disks of the same driver. Defaults have
    | been setup for each driver as an example of the required options.
    |
    */

    'disks' => [

        'local' => [
            'driver' => 'local',
            'root'   => storage_path().'/employee_documents/',
        ],

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

        'rackspace' => [
            'driver'    => 'rackspace',
            'username'  => 'your-username',
            'key'       => 'your-key',
            'container' => 'your-container',
            'endpoint'  => 'https://identity.api.rackspacecloud.com/v2.0/',
            'region'    => 'IAD',
        ],

    ],

];

我在 Laravel 5.5 上遇到了同样的问题，解决方案是使用

Storage::disk('public')->exists($file_name)

代替

Storage::exists($file_name)

默认情况下，在我的 config/filesystem.php 上，我有两种类型的本地磁盘（本地和公共），但我不知道：

    'disks' => [

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

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

    's3' => [
        'driver' => 's3',
        'key' => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_DEFAULT_REGION'),
        'bucket' => env('AWS_BUCKET'),
    ],

],

我真的不知道它在你的情况下不起作用的原因。我在我的机器上试过它工作正常。

我试图调试它里面的Storage::exits东西使用相同return file_exists($path);

这可能是原因

file_exists() 的结果被缓存

试试这些东西

  1. php工匠配置：缓存
  2. php工匠缓存：清除
  3. php工匠视图：清除
  4. chmod -R 777 storage/ 或 chown -R webuser:webuser storage/

这可能会对您有所帮助。它与 Laravel5.4 一起使用：

Storage::exists('dir/'. $filename)

if(File::exists('filePath')){
     dd(var_dump("it did exist"));

}else{
   dd(var_dump("it did not exist"));
}

请尝试上面的代码
