postman測試介面

1.1 測試登入介面，獲取token

http://192.168.56.100:8888/user/login/

'''自定義認證和許可權優先順序更高，可以覆蓋settings.py中的 ''' 
# 自定義許可權類 
permission_classes = (MyPermission,) 
# 自定義認證類, 自定義會覆蓋全域性配置 
authentication_classes =(JSONWebTokenAuthentication,)

　1.2 使用獲得的token獲取所有使用者資訊

http://192.168.56.100:8888/user/user/
