android - openssl s_client -connect 默认为子域？

Question

过去两天我一直在试图找出为什么我的 android 应用程序在使用以下代码连接到我的网站时出现“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);

我使用了 SSL Labs 检查器，我的证书以 A 级通过，并且 SSL 链没有问题(我在这里阅读了很多帖子，声称这是问题所在)。无论如何，我认为这是 android 的问题，我正在尝试许多不同的建议。

我发现了一个在我的服务器中输入以下命令的建议:

openssl s_client -connect mysite.co.uk:443

看结果的时候，打印出来的是我设计站点的自签名证书!显然这不是预期的!

这是我的主站点(域和 www)以及设计站点的三个虚拟主机配置文件

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

当我运行时:

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

然后运行:

openssl s_client -connect mysite.co.uk:443

然后我获得了 mysite.co.uk 的证书详细信息，我的 Android 应用程序再次运行。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

因为您在同一个 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，所以您需要使用 SNI(服务器名称指示)。这会在 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

虽然当前所有浏览器都默认使用 SNI，但看起来 android 默认不使用 SNI，因此可能只会从默认服务器获取证书。我自己不是 android 程序员，但是在 stackoverflow 和其他地方有几个关于 SNI 与 android 的讨论表明，它可能是可能的，但可能不是 DefaultHTTPClient 类。
