openssl s_client -connect默认为子域名？

Question

我花了最近两天试图弄清楚为什么我的Android应用程序在使用以下代码连接到我的网站时获得"无对等证书"异常错误:

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://mysite.co.uk/android/login.php");
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpclient.execute(httppost, responseHandler);

我使用过SSL实验室检查程序,我的证书通过了A级,没有SSL链问题(我在这里读了很多帖子声称这是问题所在).无论如何,认为它是android的错误我尝试了许多不同的建议.

我发现了一个建议,将以下命令输入我的服务器:

openssl s_client -connect mysite.co.uk:443

在查看结果时,它打印出我设计网站的自签名证书!显然这不是预期的!

以下是我的主站点(域和www)的三个虚拟主机配置文件,然后是设计站点

mysite.co.uk.conf:

这也位于我的apache配置文件中

SSLUseStapling on
SSLStaplingResponderTimeout 5
SSLStaplingReturnResponderErrors off
SSLCACertificateFile /etc/apache2/ssl/mysite.co.uk/gs_intermediate_ca.crt
SSLStaplingCache shmcb:/var/run/ocsp(128000)

SSLProtocol -ALL +TLSv1 +TLSv1.1 +TLSv1.2
SSLHonorCipherOrder on
SSLCipherSuite ECDHE-RSA-AES128-SHA256:AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH
SSLInsecureRenegotiation off

当我跑:

sudo a2dissite design.mysite.co.uk
sudo service apache2 restart

然后运行:

openssl s_client -connect mysite.co.uk:443

然后我得到mysite.co.uk的证书详细信息,我的Android应用程序再次工作.我在这里错过了什么吗？为什么我的服务器默认为设计网站？

Answer 1

因为您在同一IP地址后面有多个主机名,并且每个主机名都有自己的证书,您需要使用SNI(服务器名称指示).这将在SSL握手中发送所需的主机名.要使用openssl对此进行测试,您必须使用-servername参数,例如

openssl s_client -servername mysite.co.uk -connect mysite.co.uk:443

虽然所有当前浏览器默认使用SNI,但看起来android默认情况下不使用SNI,因此可能只从默认服务器获取证书.我自己不是一个Android程序员,但有几个关于SNI与stackoverflow和其他地方的android的讨论表明,它可能是可能的,但可能不是DefaultHTTPClient类.
