Generate QR code through qrcode
The code of the online tutorial can be used
Simple and crude
import qrcode img = qrcode.make('http://lizhiyu.iteye.com/blog/2331662') img.save('test.png') 加参数控制 Python代码 import qrcode qr = qrcode.QRCode( version=1, error_correction=qrcode.constants.ERROR_CORRECT_L, box_size=10, border=4, ) qr.add_data('http://lizhiyu.iteye.com/') qr.make(fit=True) img = qr.make_image() img.save('123.png')
Parameter meaning:
version: an integer with a value of 1~40, controlling the size of the QR code (the minimum value is 1, which is a 12×12 matrix). If you want the program to determine this automatically, set the value to None and use the fit argument.
error_correction: Control the error correction function of QR code. Possible values are the following 4 constants.
ERROR_CORRECT_L: About 7% or less of errors can be corrected.
ERROR_CORRECT_M (default): About 15% or less of errors can be corrected.
ROR_CORRECT_H: About 30% or less of errors can be corrected.
box_size: Controls the number of pixels contained in each small grid in the QR code.
border: Control the number of grids included in the border (the distance between the QR code and the image border) (the default is 4, which is the minimum value specified by the relevant standards)
Problem 1. Classic error, the file name uses the keyword qrcode.py , just change the file name to aaa.py
AttributeError: 'module' object has no attribute 'make'
Question 2. After modification, the error is still reported as follows, you need to install the PilImage package
Traceback (most recent call last): File "E:\python_test\qrtest\aaa.py", line 3, in <module> img = qrcode.make('http://www.xgezhang.com/') File "C:\Python27\lib\site-packages\qrcode\main.py", line 11, in make return qr.make_image() File "C:\Python27\lib\site-packages\qrcode\main.py", line 271, in make_image from qrcode.image.pil import PilImage File "C:\Python27\lib\site-packages\qrcode\image\pil.py", line 8, in <module> import Image ImportError: No module named Image 问题3.pip install PilImage报错 ,由于用的windows环境写工具,直接到piliage官网下载exe执行,解决 Could not find a version that satisfies the requirement PilImage (from version s: )
