Hi,
I think we have bug in documentation for debugging option when I put like this:
# config/packages/dev/mercure.yaml
mercure:
enable_profiler: '%kernel.debug%'I have this :
$ bin/console de:config mercure
In ArrayNode.php line 327:
Unrecognized option "enable_profiler" under "mercure". Available options are "default_hub", "hubs". And when i put like this :
# config/packages/dev/mercure.yaml
mercure:
hubs:
enable_profiler: '%kernel.debug%'
default:
url: '%env(MERCURE_PUBLISH_URL)%'
jwt_provider: App\Services\Mercure\JwtProviderI have this :
$ bin/console de:config mercure
In MercureExtension.php line 51:
Notice: Undefined index: jwt_provider Thanks
Hi,
I actually get that error when I try to open the mercure panel in my profiler.
Neither the property "targets" nor one of the methods "targets()", "gettargets()"/"istargets()"/"hastargets()" or "__call()" exist and have public access in class "Symfony\Component\Mercure\Update".
Error in : mercure.html.twig (line 70)
The signature of method "Symfony\Component\DependencyInjection\Alias::setDeprecated()" requires 3 arguments: "string $package, string $version, string $message", not defining them is deprecated.
Problem is in MercureExtension class, line 98.

api-platform/core#4264
Any idea why mercure returns 401 when publisher field private is set to true?
With false works just fine.
Documentation and examples are showing how to use Mercure from one place. But with Stimulus, each controller could listen to different topics.
What would be the best practice? Is there a recommended pub/sub library that would share the connection and work nicely with Stimulus?
Note that I assumed opening multiple SE connections hurts the server. I don't know if browsers are smart enough to internally share the connection if the URL has already been used.
Here:
Config example
mercure:
enable_profiler: '%kernel.debug%'
hubs:
default:
url: '%env(MERCURE_PUBLISH_URL)%'First of all, great job!
I've installed this bundle to be able to use it alongside the api platform package, and after configuring the env vars, I tried to add the mercure option to the @ApiResource(mercure=true) annotation and I'm getting the following error:
Unknown property "mercure" on annotation "ApiPlatform\Core\Annotation\ApiResource".
Here is my current version from some packages involved:
"name": "api-platform/api-pack",

Hello,
I use MercuryBundle for my project symfony. It work when I notify everyone, however, if I want to notify a particular user it does not work!, i can not transfer the cookie that has been generating to my hub.
Still, I put in my javascript option withCredentials: true:
const eventSource = new EventSource(url, {withCredentials: true});
thanks
Hello, we have a project on Symphony 4 + Api platform. We use Mercure and it works nice but there is one question about serialize " server-sent events". Why when i am getting server-event and if my Json contains a one nested element then this element is an array of one object, but if i am getting the same Json from Mercure(server-event) this element is just an object. I need to get an array of one object. How i can do it?
Hi,
Thank for this great project. We have an issue:
What value can we set in mercure config of the bundle with multiple domain to avoid Unable to create authorization cookie for a hub on the different second-level domain?
Thanks
Hi everyone!
I'm trying to integrate Mercure into my application by following this guide: https://symfony.com/doc/current/mercure.html
All is good until I create the PublishController. When this happens, Symfony breaks and keeps on telling me that The service "security.authentication.provider.guard.main" has a dependency on a non-existent service "App\Services\LoginFormAuthenticator".
My configuration should be fine. I checked every similar issue, but cannot seem to resolve it. I'll be happy to provide more details/config files if needed. Thanks!
implementing first hello word according here got this error. why? what is this file and where?
Unable to publish the update to the Mercure hub: file_get_contents(): Filename cannot be empty
UPDATED
i change many params and last get:
Unable to publish the update to the Mercure hub: file_get_contents(http://127.0.0.1:3000/hub): failed to open stream: HTTP request failed! HTTP/1.0 401 Unauthorized
We are trying to find a good and easy way to handle relations.
I explain, I have :
I want to get notified when I create an Url related to the Website, I want the topic Website to be updated.
For now, I manually change a property in the parent (for example a field updatedAt).
Can I use some better way ? Or did I miss something in the doc ?
This bundle currently requires lcobucci/jwt ^3.4|^4.0 and is therefor the only dependency that is currently blocking me to upgrade to the latest JWT lcobucci/jwt release.
Note that the v5 release might need some work here as the release removes deprecated components, makes PHP 8.1 the minimum required version and ships some API improvements.
Mercure allow to have two secret, but the bundle only allow one.
hi,
is it possible to know if someone is online with MercureBundle ? and He is writing ?
Thanks
I installed mercure-bundle in my symfony with default values, just switched the URL of mercure to the my own.
MERCURE_JWT_SECRET="!ChangeMe!"
And mercure is also running with default config.
SERVER_NAME=:3000 MERCURE_PUBLISHER_JWT_KEY='!ChangeMe!' MERCURE_SUBSCRIBER_JWT_KEY='!ChangeMe!' ./mercure run -config Caddyfile.dev
But i got an Unauthorized response
Then i tested in many ways to get it working and finally i found the problem:
When I copy the Token to decode it, the expiration date appears to be in an incorrect format.
If I remove the quotes, converting the string into decimal value, the expiration date appears to be correct.
Finally I tested with both tokens, first the token generated by symphony and then with decimal expiration date.
Mercure: 0.10.4 (Darwin)
Symfony: 5.2
Symfony mercure-bundle: 0.3.2
I don't know if it is a mistake done by me or is a real bug, i hope someone can help me.
Thanks

So, from what I understand, something wrong with dispatching events.
It happened after upgrading legacy mercure binary to the latets build with caddy GO lang server and moving it to separate server.
Subscriptions seems to be working, but events are never dispatched now.
Spent a lot of time trying to figure out is this mercure, caddy or symfony bundle, or transport (Redis) issue.
But because JwtToken is never applied, could be smth wrong with the bundle during invocation or dispatching.
Caddy server does not receives any updates, post requests according to logs.
Tell me please what could be the issue?
As of Chrome 88, cookies must be SiteSite=Lax/Strict or SiteSite=none; Secure. That means running a Mercure server on http isn't possible when running a Symfony dev server on https. I've tried upgrading to Mercure v0.11 with HTTPS, but that uses a self-signed certificate that isn't trusted by Chrome. I tried to use the "allow-insecure-localhost" flag in Chrome, but that flag has been removed in Chrome 88. I found a workaround by setting temporary-unexpire-flags-m87. That works only temporarily and isn't a great developer experience either.
It would be great if we can use the Symfony certificate for Mercure as well, like we can with Webpack Encore's dev server.

Hi,
I've found that with the last mercure-bundle 0.3 and the last mercure server 0.11.3 there is an issue with the generated JWT token.
The generated token looks like :
{
"exp": 1621589724.242307,
"mercure": {
"publish": [
"*"
],
"subscribe": []
}
}
And mercure send a 401 error when trying to publish with it.
I've tryed the same token generated but with the removal of "exp": 1621589724.242307, and it worked just fine when publishing in the debug UI !
I haven't found yet how to remove it automatically , maybe somehting with LcobucciFactory to handle.
Hi,
I'm using two topics on my symfony-project:
/user/notification/{userid} -> Send notifications to user (flash messages, statusupdates)
/user/messenger/{userid} -> Messages from other users
Both (private) topics were created by diefferent symfony-services.
At the client-side I'm using different stimulus-controllers:
"eventEndpoint": mercure(notificationChannelName, { subscribe: notificationChannelName })
"eventEndpoint": mercure(messengerChannelName, { subscribe: messengerChannelName})
Both topics are working perfect.
But when I'm using both on the same page, I get this error:
An exception has been thrown during the rendering of a template ("The "mercureAuthorization" cookie for the "default hub" has already been set. You cannot set it two times during the same request.").
I have no idea how to fix this.
I think I can set the cookie by myself:
$authorization->setCookie($request, ['/user/notification/{userid}','/user/messenger/{userid}']);
But the mercure-twig-helper still tries to set the cookie. -> Error again.
What can I do?
Hi,
Could you release a release for Symfony 7? Please
Thanks 😃
Right now, I have to use Nginx instead of Docker image. But for last 2 days, I tried infinite number of combinations to make it work; the only one that did work was one with symfony server:start but that can't be put on server.
From multiple nginx configs tried, this is the one I don't get exceptions anymore: (used mysite.flex as an example):
server {
listen *:80;
server_name *.mysite.flex mysite.flex;
root /mnt/Development/mysite/public;
location ~ ^/.well-known/mercure {
proxy_pass http://localhost:3000;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Authorization $http_authorization;
proxy_pass_header Authorization;
}
location / {
try_files $uri /index.php$is_args$args;
add_header 'Access-Control-Allow-Origin' '*';
}
location ~ ^/index\.php(/|$) {
add_header Access-Control-Allow-Origin *;
fastcgi_pass unix:/run/php/php8.0-fpm.sock;

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
fastcgi_param BASE_URL mysite.flex;
proxy_ignore_client_abort on;
}
}
Mercure is listening at localhost:3000. When I execute code like this (made a command):
$update = new Update( '/new_pbx_call', 'test' );
$this->hub->publish($update);and open either http://localhost:3000/.well-known/mercure?topic=%2Fnew_pbx_call or http://whitenights.flex/.well-known/mercure?topic=%2Fnew_pbx_call, nothing happens except for infinite loading.
But same thing did work when I used symfony server:start.
Mercure reports this:
My hub.url value is url: 'http://localhost:3000'. When I change it to http://localhost:3000/.well-known/mercure then I get 401:
even though JWT is identical.
Any help? I would be happy just to make basic functionality first, will fine tune it later.

I have a problem with publishing events with Hub service. Mercure returns error 400 and message "Missing "topic" parameter when I'm using pure PHP code to send requests all works correctly.
Bundle version: 0.3.4
Component: v0.6.1
Symfony: 5.4
Bundle configuration is simplest:
mercure:
hubs:
default:
url: '%env(MERCURE_URL)%'
jwt: '%env(MERCURE_JWT_TOKEN)%'
Example code:
$update = new Update(
'test',
json_encode(['key' => 'updated value 4'])
);
$data = $this->hub->publish($update);
var_dump($data);
define('DEMO_JWT', $this->hub->getProvider()->getJwt());
$postData = http_build_query([
'topic' => 'test',
'data' => json_encode(['key' => 'updated value 3']),
]);
echo file_get_contents($this->hub->getUrl(), false, stream_context_create(['http' => [
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded\r\nAuthorization: Bearer ".DEMO_JWT,
'content' => $postData,
]]));
var_dump($data); returns Missing "topic" parameter
as you can see in pure PHP code I'm using values (URL and token) from HUB and publish works.
Hello,
Assume that I want to subscribe to two (or more) private updates. By intuition I'd write this:
<div data-mercure-url="{{ mercure('https://example.com/user/3', { subscribe: 'https://example.com/user/3' }) }}"></div>
...
<div data-mercure-url="{{ mercure('https://example.com/books/1', { subscribe: 'https://example.com/books/1' }) }}"></div>But doing so will cause the following exception from Symfony\Component\Mercure\Authorization::updateCookies:
An exception has been thrown during the rendering of a template ("The "mercureAuthorization" cookie for the "default hub" has already been set. You cannot set it two times during the same request.").
I am currently working around this by specifying all subscribing URLs in one of the mercure() function call:
<div data-mercure-url="{{ mercure('https://example.com/user/3', { subscribe: ['https://example.com/user/3', 'https://example.com/books/1'] }) }}"></div>
...
<div data-mercure-url="{{ mercure('https://example.com/books/1' }}"></div>This works, but doesn't look straightforward. Is this a limitation of the current implmentation of the bundle, or am I doing it wrongly?
in this pr https://github.com/dunglas/mercure/pull/156/files was added support for RS256 algorithm, but I can't make it work with current bundle.
that's how I used to use it with HS256
SERVER_NAME=:3000 JWT_KEY='cat config/jwt/public.pem' PUBLISHER_JWT_KEY='!ChangeMe!' ./mercure run -config Caddyfile.dev
with RS256 it's supposed to work like this
SERVER_NAME=:3000 MERCURE_JWT_KEY=cat config/jwt/public.pem ./mercure run -config Caddyfile.dev
but it gives me the error a JWT key for publishers must be provided
however mercure documentation says
PUBLISHER_JWT_KEY | must contain the secret key to valid publishers' JWT, can be omited if JWT_KEY is set
I'm stuck with this problem, will be grateful for any advices, thanks
Hello,
I'm having a weird issue with Mercure, here's my .env file :
MERCURE_PUBLISH_URL=http://whateverurl/.well-known/mercure
When I output it like so :
parameters:
test: '%env(MERCURE_PUBLISH_URL)%'
In a controller : dd( $this->getParameter( 'test' ) );
I get : http://127.0.0.1:8000/.well-known/mercure
I'm trying on a Windows machine, I use Symfony 5.2.4, fresh install with Mercure Bundle 0.2.6
Build a custom jwt provider (as stated in the docs)
The Mercure Datacollector uses the whole publisher (object)
Symfore security UsageTrackingTokenStorage uses the ContainerInterface (sessionLocator) which results in the above closure call.
The Symfony debug toolbar will break:
request.CRITICAL: Uncaught PHP Exception Exception: "Serialization of 'Closure' is not allowed" at /app/vendor/symfony/http-kernel/Profiler/FileProfilerStorage.php line 175 {"exception":"[object] (Exception(code: 0): Serialization of 'Closure' is not allowed at /app/vendor/symfony/http-kernel/Profiler/FileProfilerStorage.php:175)"}
Symfony version(s) affected: 4.3.6
Description
Hi, Please i have a problem.
After installing mercure bundle who come with symfony/http-client, when i load a simple page, the toolbar didn't show again and i have this error below :
Nov 11 01:18:22 |CRITI| REQUES Uncaught PHP Exception ErrorException: "Warning: curl_multi_setopt() expects parameter 1 to be resource, integer given" at /var/www/html/project_sf4/vendor/symfony/http-client/CurlHttpClient.php line 302 exception="[object] (ErrorException(code: 0): Warning: curl_multi_setopt() expects parameter 1 to be resource, integer given at /var/www/html/project_sf4/vendor/symfony/http-client/CurlHttpClient.php:302)"
Nov 11 01:18:23 |ERROR| SERVER GET (500) /_wdt/1d91a6
How to reproduce
Just install mercure bundle
composer require mercure
When the bundle is installed, there's a lot of moving pieces to get it all working. Sentry has the same problem and their bundle provides a sentry:test command which pushed a fake event to Sentry, allowing you to see your config and keys are correct and working.
This bundle could do the same, provide a basic command to check your hub is operational, Symfony can reach it and can read from it / write to it. The same command could be used to both publish and subscribe (in another window). Alternatively, it could show a sample curl command to use to test using that.
Hi @dunglas, it's possible pass additionals payload to mercure twig function!? Any example of it?
Thank you.
I use Mercure out of Api Platform ecosystem with mercure() Twig function in template to notify the completion of tasks executed in the background, or update graphics in real time, and other updates that do not need to be private but must be reflected in the web interface. All this works fine.
mercure recipe:

If user init sesion in web app, and copy the mercure url request (
https://squidmgr.lan/.well-known/mercure?topic=squid%2Fstatus&topic=sysinfo%2Freport&topic=server%2Ftools%2Fdatetime&topic=internet%2Fstatus&topic=cuote%2Fconsumo-total&topic=notif%2Ftask-complete%2F2nC0OMu3USsHE0AdKkreLz&topic=notif%2Flist%2Flatest%2F2nC0OMu3USsHE0AdKkreLz), logout application session and paste copied url in browser all messages related to the topics present in the copied url remain accessible, if the same user init session in another browser or computer, the updates of topics that include the user id are visible in the browser that access directly to mercure request url. On the other hand, if the user closes the browser, reopens it and pastes the url, then the message Unauthorized by Mercure is displayed. It's suppose that when logout process occur, the mercureAuthorization cookie is destroyed??? Publics updates don't care that be accessible out of the session, but privates Updates is necessary that do not be accessible out of user session.
I need that'notif/task-complete/{userId}' or 'notif/list/latest/{userId}' for example, don't be accessible if user logout.
Hi, how can i integrate this bundle in my stateless app ?
Note: I already have a token generated after the authentication of the user; I would like to use this token as the Authorization Bearer in mercure
Hello,
I try to use mercure in my functionnal tests, i followed the doc but it does not work. I'd like to have a fake class exactly like the doc suggests.
I use symfony 6.3, phpunit 9.5. I tried to configure the default class like this :
mercure.hub.default:
class: App\Tests\Functional\Stub\HubStub
I have this error
Symfony\Component\Config\Exception\LoaderLoadException : Container extension "mercure.hub.default" is not registered in /srv/config/packages/mercure.yaml (which is being imported from "/srv/src/Kernel.php").
The bundle works fine in development mode, it's well imported. In the bundles.php, it's all => true setted
I tried to use the default_hub but it's not working either.
Do you have any ideas or recommandations ?
Thanks :)
