lumen使用predis访问redis集群

目录

介绍

编辑 bootstrap\app.php

修改环境变量 .env

配置项 修改 vendor\laravel\lumen-framework\config\database.php

配置路由 routes\web.php

配置控制器 创建目录和文件  app\Http\Controllers\Cache\CacheController.php

创建自定义打印方法 app\helpers.php

最后访问 路由地址  http://localhost/cache

介绍

Predis是一个开源的高级密钥值存储。它通常被称为数据结构服务器，因为键可以包含字符串、散列、列表、集和排序集。

在将Redis与Laravel一起使用之前，您将需要通过Composer安装predis/predis包：

predis适用于 redis集群架构

composer require predis/predis

 或者，您可以通过PECL安装redisphp扩展。该扩展安装起来更复杂，但对于大量使用Redis的应用程序可能产生更好的性能。

编辑 bootstrap\app.php

$app->router->group([

修改环境变量 .env

配置项 修改 vendor\laravel\lumen-framework\config\database.php

以下是示例；
default是默认的Redis连接对象名，值是连接对象的参数；app('redis.connection')返回的就是该默认连接对象；

mydefine是笔者定义的Redis连接对象名；通过执行app('redis')->connection('myredis')可以获取该连接对象；

mycluster1是笔者定义的Redis集群对象名；通过执行app('redis')->connection('mycluster1')可以获取该集群对象；

// 修改redis 配置 使用predis

            ],
        ],

    ],

配置路由 routes\web.php
 

get('/', function () use ($router) {
    return $router->app->version();
});

$router->get('/cache', 'Cache\CacheController@cache');

配置控制器 创建目录和文件  app\Http\Controllers\Cache\CacheController.php

connection('mycluster1');
        $str = 'awefawe';
        $redis->set('libc',$str);
        $time_start = microtime(true);
        $result = $redis->get('libc');
        $time_end = microtime(true);
        $time = $time_end - $time_start;
        p($result);
        p($time);
        $redis->set('libc1',1231);
        $time_start = microtime(true);
        $result = $redis->get('libc1');
        $time_end = microtime(true);
        $time = $time_end - $time_start;
        p($result);
        p($time);
        $redis->set('libc2',1232);
        $time_start = microtime(true);
        $result = $redis->get('libc2');
        $time_end = microtime(true);
        $time = $time_end - $time_start;
        p($result);
        p($time);
    }
}

创建自定义打印方法 app\helpers.php

';
        var_dump($a);
        echo '

'; } }

修改 composer.json
