SSL握手失败Java

Question

我正在学习SSL通信，我遇到了这个问题。我正在编写一个简单的客户端，它试图与本地apache服务器握手。服务器启用https。我将服务器证书添加到所有可能的信任存储（jdk中的一个

注意：我从以下教程中获取了代码：

停留在NEED_TASK状态的握手代码如下：

void doHandshake(SocketChannel socketChannel, SSLEngine engine,
            ByteBuffer myNetData, ByteBuffer peerNetData) throws Exception {

        // Create byte buffers to use for holding application data
        int appBufferSize = engine.getSession().getApplicationBufferSize();
        ByteBuffer myAppData = ByteBuffer.allocate(appBufferSize);
        ByteBuffer peerAppData = ByteBuffer.allocate(appBufferSize);
        // Begin handshake
        engine.beginHandshake();
        SSLEngineResult.HandshakeStatus hs = engine.getHandshakeStatus();
        int i=0;
        // Process handshaking message
        while (hs != SSLEngineResult.HandshakeStatus.FINISHED &&
            hs != SSLEngineResult.HandshakeStatus.NOT_HANDSHAKING) {
            i++;
            switch (hs) {

            case NEED_UNWRAP:
                // Receive handshaking data from peer
                if (socketChannel.read(peerNetData) < 0) {
                    // The channel has reached end-of-stream
                }

                // Process incoming handshaking data
                peerNetData.flip();
                SSLEngineResult res = engine.unwrap(peerNetData, peerAppData);
                peerNetData.compact();
                hs = res.getHandshakeStatus();

                // Check status
                switch (res.getStatus()) {
                case OK :
                    // Handle OK status
                    break;

                // Handle other status: BUFFER_UNDERFLOW, BUFFER_OVERFLOW, CLOSED

                }
                break;

            case NEED_WRAP :
                // Empty the local network packet buffer.
                myNetData.clear();

                // Generate handshaking data
                res = engine.wrap(myAppData, myNetData);
                hs = res.getHandshakeStatus();

                // Check status
                switch (res.getStatus()) {
                case OK :
                    myNetData.flip();

                    // Send the handshaking data to peer
                    while (myNetData.hasRemaining()) {
                        socketChannel.write(myNetData);
                    }
                    break;

                // Handle other status:  BUFFER_OVERFLOW, BUFFER_UNDERFLOW, CLOSED

                }
                break;

            case NEED_TASK :
                Runnable task =engine.getDelegatedTask();
                if(task!= null) {
                    //task.run();
                    new Thread(task).start();
                }// Handle blocking tasks

                break;

            // Handle other status:  // FINISHED or NOT_HANDSHAKING

            }
        }
        // Processes after handshaking

    }

任何帮助都将不胜感激。

Answer 1

问题是我对engine.getHandShakeStatus（）方法的理解不完整。

我把上面的代码改成了

 case NEED_TASK :
            Runnable task =engine.getDelegatedTask();
            if(task!= null) {
                //task.run();
               new Thread(task).start();
            }
            hs = engine.getHandshakeStatus();
            break;

现在它完成了握手
