- A . #Modify device resource operation def set (self, uri, req data): ret = self. rest_ call ("POST, uri, req _data) return ret
- B . #Query device resource operation def get (self, uri, req data = None): ret = self. rest_ call ("GET", uri, req _data) return ret
- C . #Delete device resource operation def delete (self, uri, req data): ret = self. rest_ call ("DELETE", uri, req data) return ret
