站长图库向大家介绍了TP6框架,Redis操作服务类等相关知识,希望对您有所帮助
下面给大家分享ThinkPHP6中Redis操作服务类的记录，希望对需要的朋友有所帮助！
1. 定义服务类
<?php declare (strict_types=1); namespace app\api\service\common; use think\facade\Cache; /** * 缓存服务 * Class RedisService * * @package app\api\service\common */class RedisService{ private $expire; private $expire_at; /** * 获取redis句柄 * * @return object|null */ public function client(): ?object { return Cache::store('redis')->handler(); } /** * 处理缓存key（添加前缀...） * * @param string $key key * * @return string */ private function cacheKey(string $key): string { return Cache::getCacheKey($key); } /** * 缓存程序运行结果 * * @param $key * @param callable $callback * @param int $expire * * @return mixed */ public function cache($key, callable $callback, int $expire = 3600) { $cache = $this->client()->get($key); if (! $cache || ! unserialize($cache)) { $data = $callback(); $this->client()->set($key, $cache = serialize($data), $expire); } return unserialize($cache); } /** * 程序运行锁 * @param $key * @param callable $callback * @param int $timeout * * @return array */ public function lock($key, callable $callback, int $timeout = 10): array { $lock = $this->client()->get($key); if ($lock) return ['code' => 0, 'data' => null]; $this->client()->setex($key, $timeout, 1); $data = $callback(); $this->client()->del($key); return ['code' => 1, 'data' => $data]; } /** * 设置有效时间 * * @param $ttl * * @return $this|false * @throws \Exception */ public function setExpire($ttl) { if ($this->expire_at) throw new \Exception('setExpire and setExpireAt can not set both'); $this->expire = $ttl; return $this; } /** * 设置到期时间 * * @param $timestamp * * @return $this|false * @throws \Exception */ public function setExpireAt($timestamp) { if ($this->expire > 0) throw new \Exception('setExpire and setExpireAt can not set both'); $this->expire_at = $timestamp; return $this; } /** * 调用原生redis方法 * * @return mixed */ public function __call($name, $arguments) { $cache_key = $this->cacheKey($arguments[0]); $result = $this->client()->{$name}(...$arguments); // 设置过期时间 $this->expire && $this->client()->expire($cache_key, $this->expire); $this->expire_at && $this->client()->expireAt($cache_key, $this->expire_at); return $result; }}2. 定义门面Facade
<?php namespace app\api\facade; use app\api\service\common\RedisService;use think\Facade; /** * Class Redis * * @package app\api\facade * * @method static \Redis client() * @method static \Redis setExpire($ttl) * @method static \Redis setExpireAt($timestamp) * @method static mixed cache($key, callable $callback, int $expire = 3600) * @method static array lock($key, callable $callback, int $timeout = 10) */class Redis extends Facade{ protected static function getFacadeClass() { return RedisService::class; }}3. 如何使用
3.1 程序锁
public function test() { $a = 1; $b = 2; $result = Redis::lock('lock:demo', function () use ($a, $b) { return $a + $b; }, 5); if ($result['code'] == 0) return '操作频繁，请稍后再试'; return $result['data']; // 成功返回数据 3 }3.2 方法数据缓存
public function test(){ $a = 1; $b = 2; $result = Redis::cache('cache:demo', function () use ($a, $b) { return $a + $b; }, 5); return $result; // 成功返回数据 3，有效时长5秒}3.3 简化过期时间设置
// 24小时到期Redis::setExpire(86400)->hSet('expire:demo', 'hash-key', 'hash-value');// 2021-08-24 23:59:59到期Redis::setExpireAt(strtotime('2021-08-24 23:59:59'))->hSet('expireAt:demo', 'hash-key', 'hash-value');3.4 普通调用
// 普通调用，直接跟redis方法名Redis::set('set:demo', 132456);// idea支持代码提示调用Redis::client()->set('set:demo', 132456);
