如何获取使用 PyQRCode 处理的 QR 码？

Question

I am trying to append an image to my pdf. I have successfully appended a barcode but I am having troubles with the QRCode. I am using PyQrCode and ReportLab

Here is my code snippers:

Where I append:

parts.append(Image(self.qrCode, width=.3* 0.7 *inch, height=.4*.56*inch))`

Where I create the QRCode:

qrCode = pyqrcode.create(str("252525"), error='L', version=27, mode='binary')
qrCode.svg(sys.stdout, scale=1)
qrCode.svg('uca-url.svg', scale=4)

number = pyqrcode.create(123456789012345)
number.png('big-number.png')

and the error that I am getting:

AttributeError at /inventories/download_tag/2525/
QRCode instance has no attribute 'rfind'

Is there a better library or method to achieve my goal here?

Answer 1

pip install pyqrcode

then

cd a_path_you_want
nano  make_qr.py

#!/usr/bin/python
import sys
import pyqrcode
text = sys.argv[1]
scale = sys.argv[2] # 1 to 8
err_prt = sys.argv[3] # error_protection in ['L','M','H']
url = pyqrcode.create(text,err_prt)
url.svg(sys.stdout, scale, module_color="brown") #this returns svg to caller script
exit(0)

be sure to

chmod +x make_qr.py

call from php

<?php
  $text = ".... your data here ....";
  echo shell_exec("path_to_script/make_qr.py '$text' 4 'L' 2>&1");
 ?>
