我正在使用laravel6。我有一个称为DriveServiceProvider的服务提供程序类。此类具有与Google Drive连接所需的所有依赖项。以下是我的服务提供商
<?php
use Hypweb\Flysystem\GoogleDrive\GoogleDriveAdapter;
use League\Flysystem\Filesystem;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Storage;
class DriveServiceProvider extends ServiceProvider
{
public function register(){
}
public function boot()
{
Storage::extend('google',function( $app,$config){
$client=new \Google_Client();
$client->setClientId($config['clientId']);
$client->setClientSecret($config['clientSecret']);
$client->refreshToken($config['refreshToken']);
$service=new \Google_Service_Drive($client);
$adapter=new GoogleDriveAdapter($service,$config['folderId']);
return new FileSystem($adapter);
});
}
}
我想将此服务提供者传递给控制器，以下是我的控制器
<?php
namespace App\Http\Controllers\Cloud;
use App\Http\Controllers\Controller;
use App\Providers\DriveServiceProvider;
use Hypweb\Flysystem\GoogleDrive\GoogleDriveAdapter;
use Illuminate\Support\Facades\Cache;
use League\Flysystem\Filesystem;
class uploadFileController extends Controller{
public $filesystem;
//Attempting Dependency Injection
public function __construct(DriveServiceProvider $filesystem) {
$this->filesystem=$filesystem;
}
public function createFolder(){
$directoryName='Demo';
$this->filesystem->createDir($directoryName);
//return $$filesystem->folder_id;
}
public function deleteFolder($id){
$this->filesystem->delete();
}
}
当我运行脚本时，它抛出了错误提示
Illuminate\Contracts\Container\BindingResolutionException
Unresolvable dependency resolving [Parameter #0 [ <required> $app ]] in class
Illuminate\Support\ServiceProvider
我的代码怎么了？任何帮助表示赞赏。
有一种更简单的方法可以在Laravel安装中执行Google云端硬盘。
composer require nao-pon/flysystem-google-drive
在filesystems.php中包括您的Google配置。
'google' => [
'driver' => 'google',
'clientId' => env('GOOGLE_DRIVE_CLIENT_ID'),
'clientSecret' => env('GOOGLE_DRIVE_CLIENT_SECRET'),
'refreshToken' => env('GOOGLE_DRIVE_REFRESH_TOKEN'),
'folderId' => env('GOOGLE_DRIVE_FOLDER_ID'),
],
现在您应该能够像这样获取文件。
Storage::disk('google')->get('yourfile');
这受以下tutorial的启发。
