1. If you import via Swagger url, the api url will end with null
for exmaple:
http://localhost/swagger/docs/v1
after imported, http://localhost/api/auth/token will change to http://locallhostnull/api/auth/token
2. http body format: x-www-form-urlencoded, use grant_type=password to auth user, it will always response “unspported grant type”, the request in backend must have some mistake I think, because SoapUi and Postman both are OK.
