Question

我花了最近两天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）。无论如何，认为它是android的错误我尝试了许多不同的建议。

我发现了在我的服务器中输入以下命令的建议：

openssl s_client -connect mysite.co.uk:443

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

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

当我跑步时：

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，但默认情况下android似乎不使用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。

Answer 2

我认为您的问题是您在两个不同的域上使用SSL，这两个域共享相同的IP地址。

由于SSL是在Web服务（HTTP）之前完成的，因此SSL无法知道用户是否正在访问design.mysite.co.uk或mysite.co.uk，它只知道它正在访问IP A上的网站，所以它正在处理它所拥有的证书，如果我正确读取的是mysite.co.uk。

然后HTTP会话启动，浏览器确认提供的证书是否与URL匹配，当您访问design.mysite.co.uk时，浏览器确认它是否匹配。

解决方案：

获取另一个IP地址并将其提供给其中一个站点，从而将您的网站的SSL访问权限分成两个单独的IP地址，每个IP地址将提供差异证书。

openssl s_client -connect默认为子域名？
