Laravel Storage::extend 不工作

Laravel Storage::extend not working

我不知道我哪里出错了。我通过 composer 安装 spatie/flysystem-dropbox 来遵循 Laravel 文档,从 Laravel 文档中复制了 DropboxServiceProvider,添加了提供给 config\app.php、运行 composer dump autoload 但我仍然收到以下错误消息:

PHP error:  Undefined index: driver in /***/vendor/laravel/framework/src/Illuminate/Filesystem/FilesystemManager.php on line 112

这里是服务提供商:

<?php

namespace App\Providers;

use Storage;
use League\Flysystem\Filesystem;
use Spatie\Dropbox\Client as DropboxClient;
use Illuminate\Support\ServiceProvider;
use Spatie\FlysystemDropbox\DropboxAdapter;

class DropboxServiceProvider extends ServiceProvider
{
    /**
     * Perform post-registration booting of services.
     *
     * @return void
     */
    public function boot()
    {
        Storage::extend('dropbox', function ($app, $config) {
            $client = new DropboxClient(
                $config['authorizationToken']
            );

            return new Filesystem(new DropboxAdapter($client));
        });
    }

    /**
     * Register bindings in the container.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

这是我的 config/app/php:

...
        /*
         * Application Service Providers...
         */
        App\Providers\AppServiceProvider::class,
        App\Providers\AuthServiceProvider::class,
        App\Providers\DropboxServiceProvider::class,
        // App\Providers\BroadcastServiceProvider::class,
        App\Providers\EventServiceProvider::class,
        App\Providers\RouteServiceProvider::class,

...

最后,这是我的 config/filesystems。php:

'dropbox'=>[
            'authorizationToken'=>env('DROPBOX_ACCESS_TOKEN')
        ],

原来我在 config/filesystems/php 中遗漏了驱动程序值,所以它应该是这样的:

'dropbox'=>[
            'driver' => 'dropbox',  <=== THIS WAS MISSING
            'authorizationToken'=>env('DROPBOX_TOKEN')
        ],

一个好的包可用于使用 dropbox 扩展存储:详细文档:https://github.com/GrahamCampbell/Laravel-Dropbox

steps for use this package :
1 : composer require graham-campbell/dropbox in your cmd window
2 : after this you have to register service provider for laravel dropbox,
    go to config/app.php
    and add 'GrahamCampbell\Dropbox\DropboxServiceProvider' this in provider array
    and 'Dropbox' => 'GrahamCampbell\Dropbox\Facades\Dropbox' this to aliases array
3: now you have to publish pacakge so 'php artisan vendor:publish' run this in your cmd
    - this will create dropbox.php file in your config in this file you have to add your credentials
4: here you have two option for connection you can use it according to your choice.

usage : 
simple example : 
use GrahamCampbell\Dropbox\Facades\Dropbox;
// you can alias this in config/app.php if you like

Dropbox::createFolder('Folder_Name');
// we're done here - how easy was that, it just works!

Dropbox::delete('Folder_Name');
// this example is simple, and there are far more methods available
