How to change the Prefix of the cache key?

[khangphung-vl]

Hello folks, I'm using this package with Redis for caching my API.

As I guess, cache prefix of the key in Spatie Cache Response is constructed from 3 separated parts:

REDIS_PREFIX . CACHE_PREFIX . unknown

This unknown string is default: "responsecache"

I already utilize REDIS_PREFIX from database.php and CACHE_PREFIX from cache.php but I couldn't figure it out where to change the unknown string. Please help.

Thanks.

It's not possible due to the "responsecache" string is built-in the Default Hasher, inside the getHashFor function. One way to work around this is write your own Hasher that extends DefaultHasher, re-implement getHashFor function to achieve the desired return string.

public function getHashFor(Request $request): string
{
    $cacheNameSuffix = $this->getCacheNameSuffix($request);

    return 'responsecache-' . hash(
        'xxh128',
        "{$request->getHost()}-{$this->getNormalizedRequestUri($request)}-{$request->getMethod()}/$cacheNameSuffix"
    );
}
