java - URL.getInputStream() 导致 java.security.cert.CertificateException : No subject alternative DNS name

Question

我有一些代码可以发送电子邮件并从模板文件中读取内容。

一切正常，直到我使用 HTTPS。在这种情况下会抛出异常:

javax.net.ssl.SSLHandshakeException: 
java.security.cert.CertificateException: No subject alternative DNS name matching lonlinux01 found.

代码

url = new URL(templateurl);
urlConnection = url.openConnection();

urlConnection.setConnectTimeout(connectionTimeout);
urlConnection.setReadTimeout(connectionTimeout);
BufferedReader breader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));

urlConnection.getInputStream()失败

应用程序的其余部分似乎在 HTTPS 上运行良好。

Answer 1

TLS 客户端在证书中找不到(完全限定)服务器名称。

您似乎正在连接到服务器 lonlinux01，但给定的服务器证书既没有通用名称 lonlinux01，也没有主题备用名称...

因此，请使用完全限定的服务器名称调整您的连接字符串(以匹配证书中的名称)，或者要求服务器管理员调整其证书(以匹配完全限定的服务器名称)
