python实现发票二维码解析

通过发票左上角的二维码信息，获取发票的关键信息，只需将图片格式的电子发票或扫描后的发票图片传入即可.
测试结果如下：

• 增值税电子普通发票：{\'发票代码\': \'031******311\', \'发票号码\': \'74****17\', \'不含税金额\': \'13665.98\', \'开票日期\': \'20210119\', \'校验码\': \'1687***********768\'}
• 增值税专用发票：{\'发票代码\': \'310****130\', \'发票号码\': \'53****64\', \'不含税金额\': \'2949.02\', \'开票日期\': \'20210614\', \'校验码\': \'\'}

def parse_invoice_info(picture):

    发票二维码解析，获取关键信息
    :param picture: 发票图片
    :return: dict
    """
    invoice_info = {}
    img = Image.open(picture)

    # 解析二维码的数据
    results = pyzbar.decode(img)

    for result in results:
        text_list = result.data.decode(\'utf-8\').split(\',\')
        invoice_info[\'发票代码\'] = text_list[2]
        invoice_info[\'发票号码\'] = text_list[3]
        invoice_info[\'不含税金额\'] = text_list[4]
        invoice_info[\'开票日期\'] = text_list[5]
        invoice_info[\'校验码\'] = text_list[6]
    return invoice_info
