如何解析安全证书子组件? [英] How to parse security certificate subcomponents?

问题描述

我正在从安全证书中读取主题，该证书的格式如下...

I'm reading the subject from a security certificate, which has the following format...

CN=x,OU=y,O=z,ST=v,C=COM

我想解析此String并仅获取CN.有没有简单的方法可以做到这一点?

I want to parse this String and get the CN only. Is there any easy way to do this?

推荐答案

是否可以在此处使用简单的正则表达式?

Is it possible to use simple regular expressions here?

没有尝试就没想到:

Pattern pattern  = Pattern.compile("CN=([^\\,])\\,")
Matcher matcher = pattern.matcher(text);
if ( matcher.find() )
{
  for (int index=1; index<matcher.groupCount();index++)
  {
    String cnValue = matcher.group(index);
  }
}
