Yii2工程配置Redis

下载yii2-redis

在composer.json中添加

"yiisoft/yii2-redis": "~2.0.0"

并执行

composer update

配置common/config/main.php

'components' => [

'redis' => [

'class' => 'yii\redis\Connection',

'hostname' => 'localhost',

'port' => 6379,

'database' => 0,

],

],

购物车接口

public function actionSetcart(){

if (isset($_REQUEST['uid'])&&isset($_REQUEST['cart'])) {

$uid = $_REQUEST['uid'];

$cart = $_REQUEST['cart'];

//Redis保存购物车数据：30分钟

$redis = Yii::$app->redis;

$redis->set('cart:'.$uid, $cart);

$redis->expire('cart:'.$uid, 30*60);

$result['error'] = 0;

$result['msg'] = '保存成功';

} else {

$result['error'] = 1;

$result['msg'] = '参数错误';

}

return $result;

}

public function actionGetcart(){

if (isset($_REQUEST['uid'])) {

$uid = $_REQUEST['uid'];

//Redis保存购物车数据：30分钟

$redis = Yii::$app->redis;

$cart = $redis->get('cart:'.$uid);

$result['error'] = 0;

$result['msg'] = '获取成功';

$result['cart'] = $cart ? $cart : '';

} else {

$result['error'] = 1;

$result['msg'] = '参数错误';

}

return $result;

}

根据IP限制接口访问

$ip = $_SERVER['REMOTE_ADDR'];

$redis = Yii::$app->redis;

$redis_ip = $redis->get('ip:'.$ip);

if ($redis_ip) {

# code...

} else {

$redis->set('ip:'.$ip, TRUE);

$redis->expire('ip:'.$ip, 60);

# code...

}
