Is the Flask service web service? Why is the WSDL file not generated? What protocol does the service use for transmission?

I just started using FLASK,. Do the services made with it belong to web service? If so, ask why the flask service did not generate a WSDL file? When you see that https://pypi.org/project/Flas. Spyne can provide support such as WSDL,SOAP for flask, when do you need to use this support?

  Flask-Spyne  can be seen. 
WSDL file is essentially a file in XM L format, which contains information about web service api interface. You can generate some web service server and client code of Java through the file in WSDL format.
