{ "access_token": "J86XVRYSNFCFI233KXDL0Q", "expires_in": 7200, "scope": "read", "token_type": "Bearer" }- Easy to use
- Based on the RFC 6749 implementation
- Token storage support TTL
- Support custom expiration time of the access token
- Support custom extension field
- Support custom scope
- Support jwt to generate access tokens
