Generate QR code in Python

There are too many advertisements for WEB services that create QR codes. Furthermore, it would be nice if only URLs and specific character strings could be converted into QR codes, but there are too many functions and it is troublesome.

Alright, then let's make it for ourselves. Is the trigger.

First of all, from the external module Insco. First of all, qrcode 5.2.2 https://pypi.python.org/pypi/qrcode

Next is image processing, so Pillow. https://pypi.python.org/pypi/Pillow

Now you are ready.

`makeqr.py`



import qrcode
from PIL import Image

img = qrcode.make("http://www.yahoo.co.jp/")
img.save('qr_code.png')

img.show()

Actually this is all, but I want to move it for myself with Ren Saba, so I will use CGI. The following are the items actually installed on Sakura Internet. Please refer to here when using an external module with Sakura.

`makeqr.cgi`



#!/usr/local/bin/python
# -*- coding: utf-8 -*-
import sys, codecs
sys.stdout = codecs.getwriter("utf-8")(sys.stdout)
import qrcode
from PIL import Image
import cgi
from datetime import datetime

print "Content-Type: text/html\n"

print """

form = cgi.FieldStorage()

newQr = form["targets"].value
today = datetime.now().strftime("%Y/%m/%d %H:%M:%S")

print "<h1>" + newQr + "</h1>"
print "<p>" + today + "</p>"
print "<p><a href=\"index.html\">Back to TOP</a></p>"

img = qrcode.make(newQr)
img.save('qr_code.png')

print "<p><img src=\"qr_code.png\"></p>"

print """

That's it.
