An interesting question about adding QR code to odoo device and generating QR code using python

In the odoo device integration, a QR code was added according to customer requirements. If I wanted to include some information, I used python's QR code library qrcode. qrcode is a Python open source library for QR code generation .

code show as below:

            ewmny = '设备：' + label.name + '，状态:' + label.zhuangtai  # + ',编号：' + label.gongsibh
            if label.zhuangtai:
                ewmny = ewmny + '，状态:' + label.zhuangtai
            else:
                ewmny = ewmny + '，状态: '
            if label.gongsibh:
                ewmny = ewmny + ',编号:' + label.gongsibh

            ewm = qrcode.make(ewmny)  # 将330*330大小的二维码
            # print(ewm.size)
            ewm.thumbnail((80, 80))
            ewmf = './tempdata/wmf.png'
            ewm.save(ewmf)

After the production is displayed, the results are scanned using WeChat and the prompts are as follows:

 

WeChat currently does not support displaying text content in QR codes.

Remember that it could be displayed before. But there is a line under WeChat that says "Copy text content". After copying and pasting it somewhere else, you can still see the content.

It said online that you can add a picture, so I tried it.

from PIL import Image
import qrcode, os

def create_qrcode(url, qrcodename):
    qr = qrcode.QRCode(
        version=1,  # 设置容错率为最高
        error_correction=qrcode.ERROR_CORRECT_H,  # 用于控制二维码的错误纠正程度
        box_size=8,  # 控制二维码中每个格子的像素数，默认为10
        border=1,  # 二维码四周留白，包含的格子数，默认为4
    )

    qr.add_data(url)  # QRCode.add_data(data)函数添加数据
    qr.make(fit=True)  # QRCode.make(fit=True)函数生成图片

    img = qr.make_image()
    img = img.convert("RGBA")  # 二维码设为彩色
    logo = Image.open("images/ewm.png")  # 传gif生成的二维码也是没有动态效果的

    w,h = img.size
    logo_w,logo_h = logo.size
    l_w = int((w - logo_w) / 2)
    l_h = int((h - logo_h) / 2)
    logo = logo.convert("RGBA")
    img.paste(logo, (l_w, l_h), logo)
    img.show()
    img.save(os.getcwd() + "/images/" + qrcodename + ".png", quality=100)

def main():
    url = input("请输入文本或URL：")
    qrcodename = input("请输入生成二维码的名称：")
    create_qrcode(url,qrcodename)

if __name__ == '__main__':
    main()

 I scanned it with WeChat and couldn’t recognize it.
