我们有用java 1.6编写的应用程序 我们开发了一个基于Bouncy Castle Libraries的定制TLSSocketConnection工厂（v.1.57）
这是TLSSocketConnection工厂的代码片段

}

}
@Override

}
}
我们使用它的方式
HttpClient httpclient = HttpClientBuilder.create().setDefaultRequestConfig(getRequestConfig()).setRedirectStrategy(new LaxRedirectStrategy()).setSSLSocketFactory(getSSLContext()).build();
logger.info(httpclient.toString());
HttpClientContext context = getHttpContext();
HttpPost httppost = new HttpPost(urlString);
HttpResponse httpResponse = httpclient.execute(httppost, context);
private RequestConfig getRequestConfig() {
return RequestConfig.custom().setConnectTimeout(320 * 1000).setConnectionRequestTimeout(320 * 1000).setSocketTimeout(320 * 1000).build();
}
private SSLConnectionSocketFactory getSSLContext() throws Exception {
return new SSLConnectionSocketFactory(new TLSSocketConnectionFactory(), new String[] { "TLSv1.2" }, null, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
}
这样我最终会在日志中收到错误
Exception: : java.io.IOException: Internal TLS error, this could be an attack

知道怎么解决吗？是由于LaxRedirectStrategy还是设置SSL套接字连接超时？ 很难弄清楚如何处理这个问题。而是从哪里开始解决这个问题。
答案 0 :(得分：1)
确定。要更新所有人，此问题已通过以下设置修复
我用v 1.59替换了v1.57并解决了这个问题。
private RequestConfig getRequestConfig（）{ return RequestConfig.custom（）。setSocketTimeout（320 * 1000）.build（）; }
