python二维码，条形码识别_zxing python java 识别条形码

利用python中的zxing包实现二维码，条形码的识别。zxing使用0.12版本，python版本为3.7，先看效果：

        再看代码： 

# -*- coding: utf-8 -*-import logging
import osimport zxing  # 导入解析包logger = logging.getLogger(__name__)
if not logger.handlers:
    logging.basicConfig(level=logging.INFO)
DEBUG = (logging.getLevelName(logger.getEffectiveLevel()) == 'DEBUG')class QRCode:
    @staticmethod
    def ocr_qr_code(path):
        """
        检测图片中是否包含二维码
        :param path: 图片路径
        :return: BarCode(raw='', parsed='', uri=None, format=None,
         type=None, points=[])
        """
        zx = zxing.BarCodeReader()
        data = ''
        # 条形码或者二维码中有中文会出现异常
        try:
            zx_data = zx.decode(path)            if zx_data:
                logger.debug(u'识别二维码:%s,内容: %s' % (filename, zx_data))
                data = zx_data
            else:
                logger.error(u'识别二维码出错:%s' % filename)
            return data
        except Exception as e:
            print(e)
        return Noneif __name__ == '__main__':

    for parent, dirnames, filenames in os.walk(filepath):

            # 将图片文件里的信息转码放到ltext里面

            logger.info(u'[%s]二维码识别:[%s]!!!' % (filename, ltext))
