So this issue has already been noticed here:
https://github.com/joomla/joomla-cms/issues/39332
My component gets accessed via the API by a big company who is using the same access with hundreds of partners all over the world.
What they do is sending only this as header:
Cache-Control: no-cache
Content-Type: application/json
It works with all partners but Joomlas route function is missing the HTTP_ACCEPT in the header and so $mediaType is empty and throwing a:
"Could not match accept header"
What can be done to have a successful API access without the partner having to send a accept header?
Update 16.01.2024
I also tried accepting different headers, but seams i cannot handle an missing accept header. This in the route creation of my webservice plugin:
public function onBeforeApiRoute(&$router)
{
$defaults = [
'component' => 'com_mycomp',
'format' => [
'application/ld+json',
'application/json',
],
];
$getDefaults = array_merge(['public' => false], $defaults);
// not working
// $app = Factory::getApplication();
// $app->setHeader('Accept', '*/*');
$routes = [
new Route(['GET'], 'v1/mycomp/time', 'mycomp.displayItem', [], array_merge(['endpoint' => 'time'], $getDefaults)),
It is described here:
https://github.com/joomla/joomla-cms/issues/39495
The getBest Function of the Negotiator requires a header:
if (!$header) {
throw new InvalidArgument('The header string should not be empty.');
}
