JHipster OAuth can't get token - 405 error - authentication

Question

I am trying to get OAuth2 token for authorization on my local JHipster server.
Everything is setup correctly and working, I can login via Web GUI.
But when I try to get token via cURL I get POST method not allowed
My cURL request is as following:
curl -X POST -vu client:secret http://localhost:8080/oauth/token -H "Accept: application/json" -d "username=admin&password=admin&grant_type=password&scope=read&client_id=CLIENTID&client_secret=CLIENTSECRET"

Answer 1

Thanks to this post, I have tested JHipster UAA, alongside JHipster version 5 .
This command could be a working sample:
curl -X POST -v http://[server-ip]:9999/oauth/token -i
-H "Accept: application/json"
-H "Authorization: Basic aW50ZXJuYWw6aW50ZXJuYWw="
-d "username=admin&password=admin&grant_type=client_credentials&scope=web-app"
Important notice:
Username and password must be replaced with yours.
The BASE64 encoded value of your 'clientId + ":" + clientSecret' must be set in header.
In my case BASE64('internal:internal')='aW50ZXJuYWw6aW50ZXJuYWw='
https://www.base64encode.org/ can be used to encode your text.
Since you have put client Id and secret on message Header, no need to provide it on message body.
And this could be a sample output:

Using the default generated jhipster app (3.5.0), this is how you would curl a token for the admin user:
> curl -X POST -u jhipsterapp:my-secret-token-to-change-in-production -i -H 'Accept:application/json' http://localhost:8080/oauth/token -d "username=admin&password=admin&grant_type=password&scope=read%20write"
HTTP/1.1 200 OK
