Google App Engine Python using POST method in MainPage
I am trying to understand an issue with Google App Engine and Python. It appears that I cannot have a POST handler in the MainPage class. Or, I am somehow using it incorrectly. The system does not object to the Python code but does not seem to find the post method. The response from the server is "405 Method Not Allowed" and "The method POST is not allowed for this resource. "
The output on the dev_appserver.py console is
INFO 2018-11-14 13:41:32,104 module.py:861] default: "GET / HTTP/1.1" 200 267
INFO 2018-11-14 13:41:35,550 module.py:861] default: "POST / HTTP/1.1" 405 188
The original source is
# -*- coding: utf-8 -*-
import webapp2
import logging
form = """
<form action="/" method="post">
<input type="checkbox" name="vehicle" value="Bike">Bike<br>
<input type="checkbox" name="vehicle" value="Car">Car<br>
<input type="submit" value="Submit" >
</form>
"""
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.write(form) # write the blank form
def post(self):
logging.info("in MainPage>post")
self.response.write("Thanks! That works !!!")
app = webapp2.WSGIApplication([
('/', MainPage),
], debug=True)
The GET method is invoked correctly and the simple form is displayed properly. The 405 error appears when I make a selection and submit the form. I have declared the form with both;
<form action="/" method="post">
and
<form method="post">
I can create an additional class that can contains a POST method and have action select the other class; everything works fine. I just have not found any logical reason it cannot correctly function in MainPage.
Thanks for your help.

I have flushed the buffers. I have even switched machines. No change. So far POST only operates in a handler class other than MainPage. But NOT when the POST method is implemented in the MainPage class.
