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...}
