i'm student and beginner, sorry in advance if i don't understand. I try to use Symfony 5 with mercure but i have some difficulty to send an update to the hub. i check the document to Symfony Mercure doc and think to make a good part about that but not all.
i have installed docker on my windows 10 and i install Mercure directly by the Symfony cli like is write on the doc. my parameter is the parameter by default that the cli install. .env
###> symfony/mercure-bundle ###
# See https://symfony.com/doc/current/mercure.html#configuration
# The URL of the Mercure hub, used by the app to publish updates (can be a local URL)
MERCURE_URL=https://127.0.0.1:8000/.well-known/mercure
# The public URL of the Mercure hub, used by the browser to connect
MERCURE_PUBLIC_URL=https://127.0.0.1:8000/.well-known/mercure
# The secret used to sign the JWTs
MERCURE_JWT_SECRET="secret"
###< symfony/mercure-bundle ###
i use a true JWT secret is just for exemple([JWT.io])2.
{
"mercure": {
"publish": [
"*"
]
}
}
with my secret password.
i create an js file with the eventSource.
const eventSource = new EventSource('http://127.0.0.1:8000/.well-known/mercure?topic=' + encodeURIComponent('http://127.0.0.1:8000/commande/recapitulatif'),
);
eventSource.onmessage = event => {
// Will be called every time an update is published by the server
alert("Commande");
console.log(JSON.parse(event.data));
}
and i would like a notification to be send when somebody access to the recap order : http://127.0.0.1:8000/commande/recapitulatif. In my controller when the address http://127.0.0.1:8000/commande/recapitulatif is call i add:
$update = new Update(
'http://127.0.0.1:8000/commande/recapitulatif',
json_encode(['status' => 'Commande'])
);
$hub->publish($update);
on the page where i need to have the notification and add the js code, if i check the connection with mercure in network of the app dev of chrome i can see this:
Request URL: http://127.0.0.1:8000/.well-known/mercure?topic=http%3A%2F%2F127.0.0.1%3A8000%2Fcommande%2Frecapitulatif
Request Method: GET
Status Code: 200 OK
Remote Address: 127.0.0.1:8000
Referrer Policy: strict-origin-when-cross-origin
but when i try to go to the url http://127.0.0.1:8000/commande/recapitulatif i have an error (Failed to send an update) and (SSL connect error for "https://127.0.0.1:8000/.well-known/mercure".)
Update: i change
MERCURE_URL=https://127.0.0.1:8000/.well-known/mercure
MERCURE_PUBLIC_URL=https://127.0.0.1:8000/.well-known/mercure
to
MERCURE_URL=http://127.0.0.1:8000/.well-known/mercure
MERCURE_PUBLIC_URL=http://127.0.0.1:8000/.well-known/mercure
and now with the error (failed to send an update) i have (HTTP/1.1 401 Unauthorized returned for "http://127.0.0.1:8000/.well-known/mercure".)
probably i need to put my app to https for have a ssl connection with mercure ?
An other try. i replace hhttp where i change https to http to my .env and js file. After that i change the code in my controller like this:
$discovery->addLink($request);
$response = new JsonResponse([
'@id' => 'http://127.0.0.1:8000/commande/recapitulatif',
'status' => 'Order',
]);
$response->headers->setCookie(
$authorization->createCookie($request, ['http://127.0.0.1:8000/commande/recapitulatif'])
);
Now i don't have error but nothing is notified to my brower.
my log for the page i want notification:
