[Tutor] if request.method == 'GET': NameError: global name 'request' is not defined

[sudipto manna]

Here is the code snippet:

File#FlaskTest2.py

from flask import Flask

app = Flask(__name__)

#Make an app.route() decorator here
@app.route("/puppies/", methods = ['GET' , 'POST'])
def puppiesFunction():
  if request.method == 'GET':
  return getAllPuppies()

  elif request.method == 'POST':
   return makeANewPuppy()

File# FlaskTendpointTester2.py
import httplib2
import json
import sys

print "Running Endpoint Tester....\n"
address = raw_input("Please enter the address of the server you want to
access, \n If left blank the connection will be set to '
http://localhost:5000':   ")
if address == '':
address = 'http://localhost:5000'
#Making a GET Request
print "Making a GET Request for /puppies..."

Virtual machine is running on port:5000

and the error trace seen on when the endpoint code is executed on localhost
port:5000

Traceback (most recent call last):
