Php 检查Aerospike数据库中是否存在密钥

请您解释一下为什么

Aerospike:：exists

方法抛出致命错误：

$aerospike = new Aerospike(
    [
        'hosts' => [
            ['addr' => '127.0.0.1', 'port' => 3000]
        ],
        'shm' => [],
    ],
    false,
    []
);

$bins = ['value' => 99];
$akey = $aerospike->initKey('test', 'cache', 'test-data');

$putStatus = $aerospike->put(
    $akey,
    $bins,
    0,
    [Aerospike::OPT_POLICY_KEY => Aerospike::POLICY_KEY_SEND]
);
var_dump($putStatus); // Aerospike::OK here

$deleteStatus = $aerospike->remove($akey);
var_dump($deleteStatus); // Aerospike::OK here

$existsStatus = $aerospike->exists($akey, $metadata); // Fatal error

测试：

$aerospike = new Aerospike(
    [
        'hosts' => [
            ['addr' => '127.0.0.1', 'port' => 3000]
        ],
        'shm' => [],
    ],
    false,
    []
);

$bins = ['value' => 99];
$akey = $aerospike->initKey('test', 'cache', 'test-data');

$putStatus = $aerospike->put(
    $akey,
    $bins,
    0,
    [Aerospike::OPT_POLICY_KEY => Aerospike::POLICY_KEY_SEND]
);
var_dump($putStatus); // Aerospike::OK here

$deleteStatus = $aerospike->remove($akey);
var_dump($deleteStatus); // Aerospike::OK here

$existsStatus = $aerospike->exists($akey, $metadata); // Fatal error
