Demonstrates how to generate a QR code using the api.qrserver.com REST API service. Chilkat2-Python

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = chilkat2.Http()

# Send the following GET request to get a binary response.
# The body of the binary response contains the image data for the QR code.
# https://api.qrserver.com/v1/create-qr-code/?data=[URL-encoded-text]&size=[pixels]x[pixels]

queryParams = chilkat2.JsonObject()

# Get a PNG file..
# Possible formats are:
# png
# gif
# jpeg
# jpg
# svg
# eps
# Case matters.  Use lowercase.
queryParams.UpdateString("format","png")

# Send the GET request to an endpoint.
# Chilkat will add the url-encoded query params passed in the JSON.

# Use the bytes in bd...
# See the online reference documentation for the function to access the bytes directly.
