caching - Redis 缓存驱动程序在 PHPUnit 中抛出异常

Question

这里有人有使用 Redis 缓存驱动程序 (CI v3.0.2) 并使用 PHPUnit (v4.8.16) 对其进行测试的经验吗？

我只是按照 here 的描述尝试了它，它似乎在浏览器中运行良好，但是当我转到我的终端并尝试使用 PHPUnit 对其进行测试时，我得到了这个:

Fatal error: Uncaught exception 'RedisException' with message 'Redis server went away' in /path/to/my-app/system/libraries/Cache/drivers/Cache_redis.php on line 317

我的环境:

$ redis-cli --version
redis-cli 3.0.5

$ php --version

我的“application/config/redis.php”文件:

<?php

/**

 * @link https://codeigniter.com/user_guide/libraries/caching.html#redis-caching
 */

$config['socket_type'] = 'tcp';
// $config['socket']      = '/var/run/redis.sock';
$config['host']        = '127.0.0.1';
$config['password']    = null;
$config['port']        = 6379;
$config['timeout']     = 0;

我该如何解决这个问题？

Answer 1

刚刚从 CI 社区论坛得到一个解决方案，它是从 CI_Cache_Redis 类扩展 __destruct() 方法来捕获 RedisException。

Here the link和这里的代码(编辑了一下)

// application/libraries/Cache/drivers/MY_Cache_redis.php
public function __destruct()
{
    try {
        $this->_redis->close();
    } catch (Exception $e) {
        // Do nothing
        // log_message('info', $e);
    }
}
