In addition, the plug-in mechanism of Neutron can only read the body in the Neutron API Request, and the GET/DELETE method has no body and cannot define the attribute by self.
However, the problem that the OpenStack Neutron API Extension mechanism cannot extend query and DELETE operations (because there is no message body in HTTP GET and DELETE methods) is caused by the strict parameter auditing mechanism and the fact that only custom parameters can exist in the message body of the Neutron REST (Representational State Transfer, which refers to a set of architectural constraints and principles) API.
