Hi Cuba Team,
I am working on REST APIs with CUBA.
I have a CUBA application through which I can create rest-api “access_token” through a Rest Client as per documentation CUBA REST API
I am also able to create entities using the access token and the required endpoints through a Rest Client.
Now, I have created another Cuba project and I want to connect to my rest-api application Rest Template. I have created the application and I am able to connect the two, and have created fetched JSON responses using GET request.
Now I am trying to create the rest-api oAuth token using the Rest Template. The endpoint is as below:
http://localhost:8585/app/rest/v2/oauth/token
As per documentation, the body of the request should contain following parameters, and request should be application/x-www-form-urlencoded.
-
grant_type-password. -
username- application user login. -
password- application user password.
How do I send the request with these parameters in the body with content type application/x-www-form-urlencoded?
Below are screenshots where I have tried to accomplish this but facing Exceptions.
