After running, execute the command to get TOKEN

curl -H "Content-Type: application/json" -X POST -d '{"username":"admin","password":"123456"}' http://127.0.0.1:8889/login

will get a JSON containing TOKEN

{
  "result": "....",
  "message": "",
  "status": 0
}

Use the TOKEN value obtained above to obtain user information

curl -H "Content-Type: application/json" -H "Authorization: Bearer TOKEN值" http://127.0.0.1:8080/users

Return result:
