The lock component for Hyperf. 中文说明

Installation

• Require

composer require friendsofhyperf/lock

• Publish

php bin/hyperf.php vendor:publish friendsofhyperf/lock -i config

Usage

You may create and manage locks using the lock() method:

$lock = lock($name = 'foo', $seconds = 10, $owner = null);

if ($lock->get()) {
    // Lock acquired for 10 seconds...

    $lock->release();
}

The get method also accepts a closure. After the closure is executed, Will automatically release the lock:

lock('foo')->get(function () {
    // Lock acquired indefinitely and automatically released...
});

If the lock is not available at the moment you request it, you may instruct the lock to wait for a specified number of seconds. If the lock can not be acquired within the specified time limit, an FriendsOfHyperf\Lock\Exception\LockTimeoutException will be thrown:

use FriendsOfHyperf\Lock\Exception\LockTimeoutException;

$lock = lock('foo', 10);

try {
    $lock->block(5);

    // Lock acquired after waiting maximum of 5 seconds...
} catch (LockTimeoutException $e) {
    // Unable to acquire lock...
} finally {
    optional($lock)->release();
}

lock('foo', 10)->block(5, function () {
    // Lock acquired after waiting maximum of 5 seconds...
});

Using by annotation

use FriendsOfHyperf\Lock\Annotation\Lock;
use FriendsOfHyperf\Lock\Driver\LockInterface;

class Foo
{
    #[Lock(name:"foo", seconds:10)]
    protected LockInterface $lock;

    public function bar()
    {
        $this->lock->get(function () {
            // Lock acquired indefinitely and automatically released...
        });
    }
}
