Hi Patrick,

thanks for the update.
I tried to install 2.1.0 but the activated Plugin-Version just gives me a greyed-out screen.
Can you please also provide 2.1.1. as with this version everything worked for me.

Thanks in advance.
Best.

Hi Patrick,

any news on this one?
Can you please email me the 2.1.1-Version so that I can at least do my exports?

Many thanks.
Best.

Ah.
Now I get it.
Thanks for helping out.

Hi Weston,

thx for the quick reply.
So I guess you are saying it’s not possible and is also not planned for future releases.

Thanks.

Thanks for the quick reply.

I get it.

But my plugin uses a POST-Request to fetch data.
It does not mutate something server-side.
I guess the authors of my used plugin [Essential Grid] decided to use a POST-Request because of authentication or something.

Nevertheless.
I managed to implement a workaround, storing my POST-Responses in IndexedDB.

Thanks for your help.
I think your plugin works great – It helped me a lot.

With this, it looks like a route can be found:

add_action(
	'wp_front_service_worker',
	function( WP_Service_Worker_Scripts $scripts ) {
		$post_cacher = function() {
			return '
				wp.serviceWorker.routing.registerRoute(
					new RegExp(\'/cv/.*\\.php\'),
					workbox.strategies.networkFirst(),
					"POST"
				);
			';
		};

		$scripts->register(
			'my-api-post-cache',
			[ 'src' => $post_cacher ]
		);
	}
);

I enabled WP_DEBUG.
When making the POST-request everything looks fine (Statucode: 200).
But when workbox tries to cache the POST-request it says this is not possible.
Here is the detailed log:

logger.mjs:44 workbox Router is responding to: /cv/wp-admin/admin-ajax.php
Found a route to handle this request: RegExpRoute?{handler: NetworkFirst, match: ?, method: “POST”}
logger.mjs:44 workbox Network request for ‘/cv/wp-admin/admin-ajax.php’ returned a response with status ‘200’.
logger.mjs:44 workbox Using NetworkFirst to respond to ‘/cv/wp-admin/admin-ajax.php’

Uncaught (in promise) attempt-to-cache-non-get-request: Unable to cache ‘/cv/wp-admin/admin-ajax.php’ because it is a ‘POST’ request and only ‘GET’ requests can be cached.

WorkboxError @ WorkboxError.mjs:33
putWrapper @ cacheWrapper.mjs:46
_getNetworkPromise @ NetworkFirst.mjs:255

So basically POST-Requests can just be registered as routes but not be cached?
I don’t get it…

Maybe you can interpret this message a bit?

Thanks in advance.

I pasted your Regex.
But this still has no effect on my POST-Request-Cache.
As said, the GET-Request on the same resource seem to work.
The only difference I can make out is, that they have a querystring attached in the url. They look like this:

https://www.XYZ/wp-admin/admin-ajax.php?action=Essential_Grid_Front_request_ajax&client_action=load_post_content&token=51ae258ba3&postid=2534&settings={%22titl%22:%22Polarisierte%20Diagramme%22,%22lbTitle%22:%22off%22,%22lbTag%22:%22h2%22,%22lbImg%22:%22off%22,%22lbMin%22:%2240%%22,%22lbMax%22:%22300px%22,%22margin%22:%2250|0|0|0%22,%22padding%22:%2225|5|30|5%22,%22overflow%22:%22auto%22,%22ispost%22:1,%22gridid%22:1}&esgbox=true

I would expect the same behaviour for POST-Request.
Do you have any hints?

Thanks.
Best.

Hi,

also tried:

add_action( 'wp_front_service_worker', function( \WP_Service_Worker_Scripts $scripts ) {
	$scripts->caching_routes()->register(
		'.*\.html',
		[
			'strategy'  => WP_Service_Worker_Caching_Routes::STRATEGY_NETWORK_FIRST,
			'cacheName' => 'TEST ',
			'plugins'   => [
				'expiration' => [
					'maxAgeSeconds' => 60 * 60 * 24,
				],
			],
			'method'   => 'POST',
		]
	);
} ); 

as my response is text/html
but the request does not get cached.
The GET-Request done on admin-ajax.php .work seamlessly.
Although the are done with a query string.

Hi Weston,

thanks for the update.
Sorry that I’m such a noobie here.
I added following code to my php API

add_action( 'wp_front_service_worker', function( \WP_Service_Worker_Scripts $scripts ) {
	$scripts->caching_routes()->register(
		'https://www.[mysite]/admin-ajax.php',
		[
			'strategy'  => WP_Service_Worker_Caching_Routes::STRATEGY_NETWORK_FIRST,
			'cacheName' => 'TEST ',
			'plugins'   => [
				'expiration' => [
					'maxAgeSeconds' => 60 * 60 * 24,
				],
			],
			'method'   => 'POST',
		]
	);
} );

But the Site still wants to post using admin-ajax.php.
I run Cloudflare and WPRocket.

Am I still doing something wrong?

Thanks.
Best.
Christoph.
