@hsluoyz need to refer to Casdoor Go SDK (https://github.com/casdoor/casdoor-go-sdk)'s code and test case code @hsluoyz The Node.js SDK code in this repo is very old. need to port the latest code from https://github.com/casdoor/casdoor-go-sdk to this code. the code should be exactly the same behavior, including source code and test cases
