首先安装redis服务器，如下安装教程地址

先在composer里安装(输入这条命令)
composer require predis/predis
2.控制器里引入Redis
use Illuminate\Support\Facades\Redis;
public function index()
{
$articles = Article::all();
Redis::select(9);
Redis::set('articles', serialize($articles));//序列化存储，反序列化取数据，避免乱码
$good = unserialize(Redis::get('articles'));
return response()->json($good);
}
