是否有任何算法可以解析或解码使用 Zxing 从条码扫描仪获得的字符串结果？
是否有任何算法可以解析或解码使用 Zxing 从条码扫描仪获得的字符串结果？
我想从扫描结果中提取批号或序列号。有没有标准的算法可以做到这一点？
我目前正在使用，
String lotNumber=scanResults.substring(24,26);
if (lotNumber.equalsIgnoreCase("10")){
System.out.println("Lot numberrrrrrrrrrr " + a.substring(26,a.length()));
}
谢谢

Is there any algorithm which can parse or decode the String results obtained from BarCode Scanner using Zxing?
I want to extract Lot number or serial number from the scanned result. Is there any standard algorithm to do so?
I currently use,
String lotNumber=scanResults.substring(24,26);
if (lotNumber.equalsIgnoreCase("10")){
System.out.println("Lot numberrrrrrrrrrr " + a.substring(26,a.length()));
}
Thanks

不，Java 或任何语言都没有魔法可以告诉您生成条形码的数据是什么。您应该了解数据并了解其内容类型（json、xml 等），然后使用解析器。或者，如果它不符合定义的标准（任何随机字符串），则按照您正在做的事情进行。
no there is no magic in java or any language which can tell you what is that data for which that bar code was generated. You should know the data and should know its content type (json, xml etc) and then use the parser. Or if its not as per the defined standards (any random string) than do as what you are doing.
查看
ResultParser类。它会尝试将结果字符串解析为更有意义的内容。例如“mailto:[email protected]”将返回为EmailParsedResult，让您知道这是一个电子邮件地址并解析出地址给你。我不确定这个批号是什么——它并不为人所知，因此没有在您的系统之外实现。但是，是的，您已经可以在项目中找到很多此类逻辑，您也许可以重用和修改它们。
Look at the class
ResultParser. It will try to parse the result string as something more meaningful. For example "mailto:[email protected]" would come back asEmailParsedResult, letting you know it's an email address and parsing out the address for you.I am not sure what this lot number is -- it's not well-known and so not implemented outside your system. But yes you can find a lot of this kind of logic in the project already, which you can perhaps reuse and modify.
