为什么 redis set 方法在 laravel 网站上出现错误？

问题描述 投票：0回答：1

在 Laravel 11 站点上，我添加了 redis 并在控制台中测试它：

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\Redis;


class RedisTest extends Command
{
    protected $signature = 'app:redis-test';

    protected $description = 'Command description';

    public function handle()
    {
        \Redis::set('city_name', 'San Francisco city');

        echo '::RedisTest::'.print_r('RedisTest::',true);

        $cityName = \Redis::get('city_name');
        echo '::RedisTest  $cityName::'.print_r($cityName,true);
    }
}

我有错误：

$ php artisan app:redis-test

   Error

  Class "Redis" not found

  at app/Console/Commands/RedisTest.php:38
     34▕      * Execute the console command.
     35▕      */
     36▕     public function handle()
     37▕     {
  ➜  38▕         \Redis::set('city_name', 'San Francisco city');
     39▕
     40▕         echo '::RedisTest::'.print_r('RedisTest::',true);
     41▕
     42▕         $cityName = \Redis::get('city_name');

      +13 vendor frames

  14  artisan:13
      Illuminate\Foundation\Application::handleCommand()

我同时使用了

\Redis::set(
和
Redis::set(
，但出现了同样的错误 我的PHPstorm也建议导入：

//use Redis;
//use SimplePie\Cache\Redis;

但有同样的错误。

在 config/database.php 中我有：

    'redis' => [

    'client' => env('REDIS_CLIENT', 'predis'),

    'options' => [
        'cluster' => env('REDIS_CLUSTER', 'redis'),
        'prefix' => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_database_'),
    ],

    'default' => [
        'url' => env('REDIS_URL'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'username' => env('REDIS_USERNAME'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', '6379'),
        'database' => env('REDIS_DB', '0'),
    ],

    'cache' => [
        'url' => env('REDIS_URL'),
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'username' => env('REDIS_USERNAME'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', '6379'),
        'database' => env('REDIS_CACHE_DB', '1'),
    ],
],

在 .env 中：

CACHE_DRIVER=file
CACHE_STORE=database
CACHE_PREFIX=

MEMCACHED_HOST=127.0.0.1

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379
REDIS_CLIENT=predis

出了什么问题，使用哪些库/方法更好？

在我的ubuntu中安装了redis，我可以使用cli控制台打开它。

更多信息：

我的命令文件已声明：

use Illuminate\Support\Facades\Redis;

我删除了 

/bootstrap/cache

中的文件

并删除文件/目录：

composer.lock 供应商

然后运行：

composer install

输出提到“predis”：

如何查看现在使用的是哪个驱动程序？在我看来，我所有的选择都是有效的......

我可以打开 redis-cli 和 phpmyadminer 并且可以查看/添加有效数据...

不是任何“redis”子目录。我认为因为我已经安装了“predis/predis”，所以我不需要任何软件包。我需要一些软件包来安装更多吗？

    "laravel/framework": "^11.9",
    "predis/predis": "^2.2",

提前致谢！

在 config/app.php 中我添加了 redis 参数：

'aliases' => Facade::defaultAliases()->merge([
    ...
    'Redis' => Illuminate\Support\Facades\Redis::class,
    ])->toArray(),

工作正常。

为什么测试文件声明中的

Illuminate\Support\Facades\Redis
不起作用我不知道......
