论坛上充满了这个问题,但我找不到解决方案。 我尝试连接WS,但没有任何成功。 我试图更新 cacerts 文件,但没有效果。
日志是:
Allow unsafe renegotiation: false
Allow legacy hello messages: true

谢谢你的帮助
很可能服务器已禁用TLS 1.0(您说的是序列字节4703 015A中的TLS 1.0),或者它正在等待不存在的SNI扩展。
关于Java 6,只有6u111允许比TLS 1.0更好的(TLS 1.1),而6u121将允许TLS 1.2。看看参考。由于TLS 版本不容忍问题,它仍然不够,只有系统属性才能永久启用它,如发行说明中所述:
TLSv1.2 现在是此版本的 TLS 协议选项。默认情况下, TLSv1.0 将保留客户端套接字上启用的默认协议。
因此,请尝试几个系统属性:
-Djdk.tls.client.protocols="TLSv1.2"
(先决条件:6U121/7U95)-Dhttps.protocols="TLSv1.2"
您的代码是否正在使用 HttpsURL 容器
您的ClientHello格式正确,但它不包含任何扩展名(尤其是 SNI)。这就是为什么它看起来这么短(字节 = 80)。默认情况下,SNI 从 6u121 开始启用(如果我是对的)。我看到的两个原因都应该用适当的Java版本来解决。
