Authorization Request: https://localhost:9096/authorize?client_id=000000&response_type=code
Grant Token Request: https://localhost:9096/token?grant_type=client_credentials&client_id=000000&client_secret=999999&scope=read

"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
