使用python进行二维码生成和识别的实现

pip install qrcode[pil]

import qrcode

# 生成二维码
def generate_qr_code(data, file_path):
    # 创建 QRCode 对象
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=10,
        border=4,
    )
    qr.add_data(data)
    qr.make(fit=True)

    # 创建图像
    img = qr.make_image(fill='black', back_color='white')
    img.save(file_path)

# 示例
generate_qr_code('https://www.example.com', 'example_qr.png')

pip install pyzbar pillow

from pyzbar.pyzbar import decode
from PIL import Image

# 识别二维码
def decode_qr_code(file_path):
    # 打开图像
    img = Image.open(file_path)
    
    # 解码二维码
    decoded_objects = decode(img)
    
    for obj in decoded_objects:
        print(f'Data: {obj.data.decode("utf-8")}')
        print(f'Type: {obj.type}')
        print(f'Bounding Box: {obj.rect}')
    
# 示例
decode_qr_code('example_qr.png')
