Try to use Service worker in my Angular7 app. ServiceWorker compiled by ServiceWorkerModule.
This issue was reproduced only if I use a service worker.
I can not understand why SW initiate auth POST request without sending pre-flight OPTIONS req.
May be anybody can help with this issue?

Occasionally I receive a connection timeout when calling the /userinfo endpoint of my KeyCloak-Server.
So far, I have no indication what's wrong and what causes the timeouts. There are no errors in the server.log I configured. Also, I cannot reproduce the issue, I just see the errors in the logs of the application trying to authenticate with keycloak.
Is there some sort of connection limit that my keycloak might use?

What additional logs can I activate to narrow down the problem?
I am currently on version 17.0.1
Try running keycloak in debug mode kc.sh start --log-level=debug If the /userinfo call reached the keycloak then there will be a debug log for that, you can match the time when error occurred to the keycloak log.
Do you have any other components in between your application and keycloak such as proxy, a DNS server etc ? You would need to check their logs as well.
Also check out this document regarding rest api in keycloak -> https://github.com/keycloak/keycloak-community/blob/main/design/rest-api-guideline.md#rate-lmiting
I am new to angular and developed an angular application using angular CLI 7.
When I am running the application from my local system, I am getting the response from the service and it is working fine.
But when I deployed the application in the production server, I am unable to get the response from the service. Service is taking too long to respond and getting the HTTPErrorResponse of status Unknown Error.
We are using the Spring microservices for api calls to get the response data.
I am using the proxy.conf.json for the services because the URL running angular app is different from the service.
proxy.conf.json:
{
"/api/*":{
"target":"http://wsd185erd986.test.com/api",
"secure":false,
"loglevel":debug,
"changeOrigin":true
}
}
Changed the package.json to include the proxy.conf.json in proxyConfig.
Include the response headers in the service.
Could any one know on how to configure these proxy settings in production build for angular. Do we need to include any headers in the service calls.
HTTPErrorResponse - A response that represents an error or failure,
either from a non-successful HTTP status, an error while executing the
request, or some other failure which occurred during the parsing of
the response.
So as per the docs this error is thrown in multiple cases either there is an error at server end and server send the error response or there was some issue in parsing.
Please check the Spring Boot API request logs to see what response code is sent back.
You can check the API by a standalone client too (like Postman) and see if there is some issue.
As an aside - you should not be using angular development server in production as it is meant for angular development. Typically you can use any web server ( like Apache, NGinx etc) to host your angular production files ( they are merely static resources) and then either use them as a proxy ( by having their proxy configuration) or have CORS enabled services.
I have a client that can only make requests without authentication information.
I would like to use HAProxy or a similar proxy solution to add OAuth authentication to these client requests.
I already succeeded to add a Bearer token to the client requests. See below for the haproxy.cfg with some placeholders.
frontend front
mode http
bind *:8080
default_backend servers
http-request add-header Authorization "Bearer {{ .Env.ACCESS_TOKEN}}"
backend servers
mode http
server server1 myserver.com:443 ssl
The problem is that the access tokens have a TTL of 24 hours. So I need to refresh them or get a new token periodically.
Does HAProxy support this already?
I can write some script to get a new access token periodically, update the config and restart HAProxy. Is this a good approach when running HAProxy in docker? Are there better solutions?
You could give a try to create/test your script using Lua, it is now supported in the latest versions, check How Lua runs in HAProxy.
An example of this but using Nginx + Lua, can be found in this project: https://github.com/jirutka/ngx-oauth
My locally running rails app (on localhost:3000) responds to requests in the browser or from curl, but is not responding to requests from the desktop postman client, which immediately gives the generic "Could not get any response". Any idea what could be causing this?
For this you can use NGROK. It provides you a tunnel which can easily be used with postman or anyother such service. Download the library from here and run the tunnel as
./ngrok http 3000
or you can use lvh.me:3000 if your request is from same machine.
I have a Rails 4 application running on Heroku. For one type of request I make a HTTP call to an external service and then return the response to the client.
As I see from the logs, the request to the external service is taking too long and resulting in the Heroku's H12 error where it sends a 503 after 30 seconds. The HTTP request that I am making to the external service eventually comes back with a Net::ReadTimeout after some more time (60 seconds).
However if I run heroku run console and make the same HTTP call (through the same Ruby code), it works just fine. The request completes in about a second or two at the max.
I am unable to understand why this request is timing out when run from the web process while it works seamlessly in the heroku run console.
I am running Puma as my webserver. I followed guidelines given here : https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server
I also tried the basic WEBrick server to see if that helps. But no avail.
Has anyone faced this issue? Any hints on how to debug this?
