python学习第二弹 URL生成二维码

一、准备工作

1. pip instaill image & pip instaill qrcode

2.png 格式的图片，命名为logo.png，放在根目录下

二、代码

importqrcodeasqrcode

fromPILimportImage

url ="http://www.jianshu.com/"

qr = qrcode.QRCode(

version=2,

error_correction=qrcode.constants.ERROR_CORRECT_L,

box_size=8,

border=2

)

qr.add_data(url)

qr.make(fit=True)

img = qr.make_image()

img = img.convert("RGBA")

icon = Image.open("./logos.png")

img_w,img_h = img.size

factor =4

size_w =int(img_w / factor)

size_h =int(img_h / factor)

icon_w,icon_h = icon.size

ificon_w > size_w:

icon_w = size_w

ificon_h > size_h:

icon_h = size_h

icon = icon.resize((icon_w,icon_h),Image.ANTIALIAS)

w =int((img_w - icon_w) /2)

h =int((img_h - icon_h) /2)

img.paste(icon,(w,h),icon)

img.save("./test.png")

运行就ok了，试试吧？
