Question

我正在使用okhttp v 2.4.0和retrofit v1.9.0来发出https请求，其中服务器仅使用Protocol TLSv1.2，我收到错误：

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0xb8e6cf68: Failure in SSL library, usually a protocol error

我从这里尝试了很多东西，但没有任何作用，我尝试使用SocketFactory设置协议，如下所示：https://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/

当服务器支持TLSv1，TLSv1.1，TLSv1.2，SSLv3时它起作用，但是当它被删除并且只让TLSv1.2它停止工作时，所以我尝试使用NoSSLv3Factory类作为许多答案在这里很难过在stackoverflow中，但也没有成功，我使用的NoSSLv3方法就是那个：How to disable SSLv3 in android for HttpsUrlConnection?

我无法解决的问题是，如果服务器不再使用该协议并且我将其从okhttp客户端删除，并且为什么它在Android 4.4.2上不起作用，我一直收到SSLv3错误的原因如果网站：https://www.ssllabs.com/ssltest表示4.4.2+与图片所示相同

如果有人有任何想法，我可以使用一些帮助
