Can someone point me in right redirection how to cache POST responses also with this package?

Hi,

I know POST responses must not be cached. But this is a special scenario and the package documentation says it only caches GET Requests.

So Do we have to implement a custom cache profile for this ?

Thanks.

@iamprageeth I think you need to implement a cache profile and cache hasher.

Here is an example:

Hasher:

<?php

namespace App\Support\Cache;

use Illuminate\Http\Request;
use Spatie\ResponseCache\CacheProfiles\CacheProfile;
use Spatie\ResponseCache\Hasher\RequestHasher;

class PostParamsAwareRequestHasher implements RequestHasher
{
    protected CacheProfile $cacheProfile;

    public function __construct(CacheProfile $cacheProfile)
    {
        $this->cacheProfile = $cacheProfile;
    }

    public function getHashFor(Request $request): string
    {
        $data = collect($request->all())->sortKeys()->toJson();

        return md5("{$request->getRequestUri()}-{$data}/".$this->cacheProfile->useCacheNameSuffix($request));
    }
}

Profile:

<?php

namespace App\Support\Cache;

use Illuminate\Http\Request;
use Illuminate\Support\Str;
use Spatie\ResponseCache\CacheProfiles\BaseCacheProfile;
use Symfony\Component\HttpFoundation\Response;

class ApiRequestCacheProfile extends BaseCacheProfile
{
    public function shouldCacheRequest(Request $request): bool
    {
        $cacheControl = $request->headers->get('Cache-Control', '');

        if (Str::contains($cacheControl, ['no-store', 'no-cache'])) {
            return false;
        }

        if ($this->isRunningInConsole()) {
            return false;
        }

        return true;
    }

    public function shouldCacheResponse(Response $response): bool
    {
        if (!$this->hasCacheableResponseCode($response)) {
            return false;
        }

        if (!$this->hasCacheableContentType($response)) {
            return false;
        }

        return true;
    }

    public function hasCacheableResponseCode(Response $response): bool
    {
        if ($response->isSuccessful()) {
            return true;
        }

        if ($response->isRedirection()) {
            return true;
        }

        return false;
    }

    public function hasCacheableContentType(Response $response): bool
    {
        $contentType = $response->headers->get('Content-Type', '');

        if (
            Str::startsWith($contentType, 'text/') ||
            Str::contains($contentType, ['/json', '+json'])
        ) {
            return true;
        }

        return false;
    }
}
