python實現發票二維碼解析

通過發票左上角的二維碼信息，獲取發票的關鍵信息，只需將圖片格式的電子發票或掃描后的發票圖片傳入即可.
測試結果如下：

• 增值稅電子普通發票：{'發票代碼': '031******311', '發票號碼': '74****17', '不含稅金額': '13665.98', '開票日期': '20210119', '校驗碼': '1687***********768'}
• 增值稅專用發票：{'發票代碼': '310****130', '發票號碼': '53****64', '不含稅金額': '2949.02', '開票日期': '20210614', '校驗碼': ''}

from pyzbar import pyzbar
from PIL import Image


def parse_invoice_info(picture):

    :param picture: 發票圖片

    """
    invoice_info = {}
    img = Image.open(picture)

    # 解析二維碼的數據
    results = pyzbar.decode(img)

    for result in results:
        text_list = result.data.decode('utf-8').split(',')
        invoice_info['發票代碼'] = text_list[2]
        invoice_info['發票號碼'] = text_list[3]
        invoice_info['不含稅金額'] = text_list[4]
        invoice_info['開票日期'] = text_list[5]
        invoice_info['校驗碼'] = text_list[6]
    return invoice_info
