我在 Fabric 上遇到以下异常:

Non-fatal Exception: javax.net.ssl.SSLPeerUnverifiedException: Hostname assets.domain.com not verified:

与安全团队一起,我们意识到这可能是用户打开我们的应用程序连接到某些酒店 Wi-Fi 并使用那些讨厌的登录页面打上烙印的情况。到目前为止,似乎只有 2 个用户受到影响,而且我们还有更多用户,所以这并不是真正的中间人攻击。

因此,我想验证异常的通用名称。如果它与我们的主机匹配assets.domain.com,则它是潜在的攻击,我想记录发生的情况。如果 CN 不同,那么我只想抑制错误。

我有哪些选择?我只能想到解析异常原因字符串并使用正则表达式提取CN=value部分。但是有没有更好的不易出错的解决方案?

tl;博士;

我想从中提取 CN 值SSLPeerUnverifiedException并将其与我们的有效主机名进行比较。实现这一目标的最佳方法是什么?

使用您提供的有限样本,它是这样的

"(?s)SSLPeerUnverifiedException:.*?(?<!\\S)CN=([^\\s,]+)(?=,)"

其中捕获组 1 包含 CN 值。

输出:

 **  Grp 0 -  ( pos 35 , len 165 )
