Create lock
use IlluminateSupportFacadesCache; $lock = Cache::lock('foo', 10); if ($lock->get()) { // 处理业务逻辑 sleep(3); $lock->release(); }
Get an indefinite lock and automatically release it
The get method can receive a closure. After the closure is executed, Laravel will automatically release the lock.
Cache::lock('foo')->get(function () { // 获取无限期锁并自动释放... });
Acquire the lock within the specified time
use IlluminateContractsCacheLockTimeoutException; $lock = Cache::lock('foo', 10); try { $lock->block(5); echo "5秒时间内成功获取锁..."; } catch (LockTimeoutException $e) { echo "5秒时间内获取锁失败..."; } finally { optional($lock)->release(); }
Or
Cache::lock('foo', 10)->block(5, function () { echo "5秒时间内成功获取锁..."; });
Ignore the owner and force release the lock
Cache::lock('foo')->forceRelease();
Cross-process management lock
// 控制器中... $podcast = Podcast::find($id); $lock = Cache::lock('foo', 120); if ($result = $lock->get()) { ProcessPodcast::dispatch($podcast, $lock->owner()); } // 队列任务中... // 使用锁名称和拥有者重新获取锁实例后再释放 Cache::restoreLock('foo', $this->owner)->release();
