问当Laravel无法连接到Redis时如何捕获异常？

EN

public function render($request, Exception $exception)
{
    if ($exception instanceof SomeRedisException) {
        return response()->json('Redis Error',500);
    }

    return parent::render($request, $exception);
}

try {
    // Call Laravel Cache facade when Redis connection is failing
    // This will throw exception
    Cache::get('cache_key');
} catch (RedisException $exception) {
    // In case Redis error - do custom response
    Log::error('Redis error', [
        'message' => $exception->getMessage(),
        'trace' => $exception->getTrace()
    ]);

    return response()->json([
        'error' => 'your error message to client'
    ]);
}
