public function showRedis($id = 1)

$user = Redis::get('user:profile:'.$id);
Xdd($user);
}
In app/config/database.php i have :
在 app/config/database.php 我有：
'redis' => [
'cluster' => false,
'default' => [
'host' => env('REDIS_HOST', 'localhost'),
'password' => env('REDIS_PASSWORD', null),
'port' => env('REDIS_PORT', 6379),
'database' => 0,
],
],
It throws the following error : No connection could be made because the target machine actively refused it. [tcp://127.0.0.1:6379]

First make sure Redis is actually listening on that port by opening up powershell and typing netstat -aon | more(this command may need to be enabled in features or installed somehow). If it is listening then check your firewall settings. If if not listening then make sure Redis is started and is configured to listen on that port.
首先，通过打开 powershell 并键入netstat -aon | more（此命令可能需要在功能中启用或以某种方式安装），确保 Redis 实际上正在侦听该端口。如果它正在侦听，请检查您的防火墙设置。如果不侦听，则确保 Redis 已启动并配置为侦听该端口。
It looks like predis/predisis a client library only. See https://packagist.org/packages/predis/predis.
看起来predis/predis只是一个客户端库。请参阅https://packagist.org/packages/predis/predis。
You need to install the Redis server, but it looks like it is not officially supported on Windows. See http://redis.io/download. Per information on that page, it looks like there is a Win64 port for Redis here https://github.com/MSOpenTech/redis.
您需要安装Redis服务器，但在Windows上似乎没有正式支持。请参阅http://redis.io/download。根据该页面上的信息，这里的 Redis 似乎有一个 Win64 端口https://github.com/MSOpenTech/redis。
If it still doesn't work after that then update your question with the new error you see.
如果在那之后它仍然不起作用，请使用您看到的新错误更新您的问题。

It is showing your server is not accepting connections from outside. You need to provide ip of your redis server.
它显示您的服务器不接受来自外部的连接。你需要提供你的redis服务器的ip。
$client = new Predis\Client('tcp://192.168.1.103:6379');
//$client = new Predis\Client();
$client->set('foo', 'bar');
$value = $client->get('foo');
echo $value; exit;
if problem still come then try below steps.
如果问题仍然存在，请尝试以下步骤。
So you need to edit : $sudo vi /usr/local/etc/redis.conf
所以你需要编辑： $sudo vi /usr/local/etc/redis.conf
and find the line bind 127.0.0.1 ::1 and change it to #bind 127.0.0.1 ::1 and then find line protected-mode yes and then change it to protected-mode no
并找到行 bind 127.0.0.1 ::1 并将其更改为 #bind 127.0.0.1 ::1 然后找到行 protected-mode yes 然后将其更改为 protected-mode no
and then restart the redis server
然后重启redis服务器
