Java ssl服务器/客户端应用程序传递字节[]

我正在用java（服务器/客户端）创建一个使用安全连接（ssl）的应用程序

主类具有套接字和流的初始化：

SSLServerSocketFactory sslserversocketfactory = (SSLServerSocketFactory) SSLServerSocketFactory
                    .getDefault();
            sslserversocket = (SSLServerSocket) sslserversocketfactory
                    .createServerSocket(port);
            System.out.println("Server: listening on port: " + port + "\n");
            System.out.println("Waiting for connection...." + "\n");
            sslsocket = (SSLSocket) sslserversocket.accept();
            connected = true;
            System.out.println("Connection accepted \n");

            InputStream inputstreamconsola = System.in;
            InputStreamReader inputstreamreaderconsola = new InputStreamReader(
                    inputstreamconsola);
            BufferedReader bufferedreaderconsola = new BufferedReader(
                    inputstreamreaderconsola);

            in = new DataInputStream(sslsocket.getInputStream());
            out = new DataOutputStream(sslsocket.getOutputStream());

 SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
          sslsocket = (SSLSocket) sslsocketfactory.createSocket("localhost", 9999);
          in = new DataInputStream(sslsocket.getInputStream());
          out = new DataOutputStream(sslsocket.getOutputStream());

服务器主类：

public static void main(String[] arstring) {
            DataOutputStream out = null;
    DataInputStream in = null;
    SSLServerSocket sslserversocket = null;
    SSLSocket sslsocket = null;
 ...

public static void main(String[] args) throws IOException {
    BufferedReader console;
    DataInputStream in = null;
    DataOutputStream out = null;
    SSLSocket sslsocket = null;
  ...

客户端主类：

public static void main(String[] arstring) {
            DataOutputStream out = null;
    DataInputStream in = null;
    SSLServerSocket sslserversocket = null;
    SSLSocket sslsocket = null;
 ...

public static void main(String[] args) throws IOException {
    BufferedReader console;
    DataInputStream in = null;
    DataOutputStream out = null;
    SSLSocket sslsocket = null;
  ...

我已经在每个类中创建了相应的套接字和流：

服务器套接字和流：

SSLServerSocketFactory sslserversocketfactory = (SSLServerSocketFactory) SSLServerSocketFactory
                    .getDefault();
            sslserversocket = (SSLServerSocket) sslserversocketfactory
                    .createServerSocket(port);
            System.out.println("Server: listening on port: " + port + "\n");
            System.out.println("Waiting for connection...." + "\n");
            sslsocket = (SSLSocket) sslserversocket.accept();
            connected = true;
            System.out.println("Connection accepted \n");

            InputStream inputstreamconsola = System.in;
            InputStreamReader inputstreamreaderconsola = new InputStreamReader(
                    inputstreamconsola);
            BufferedReader bufferedreaderconsola = new BufferedReader(
                    inputstreamreaderconsola);

            in = new DataInputStream(sslsocket.getInputStream());
            out = new DataOutputStream(sslsocket.getOutputStream());

 SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
          sslsocket = (SSLSocket) sslsocketfactory.createSocket("localhost", 9999);
          in = new DataInputStream(sslsocket.getInputStream());
          out = new DataOutputStream(sslsocket.getOutputStream());

客户端套接字和流：

SSLServerSocketFactory sslserversocketfactory = (SSLServerSocketFactory) SSLServerSocketFactory
                    .getDefault();
            sslserversocket = (SSLServerSocket) sslserversocketfactory
                    .createServerSocket(port);
            System.out.println("Server: listening on port: " + port + "\n");
            System.out.println("Waiting for connection...." + "\n");
            sslsocket = (SSLSocket) sslserversocket.accept();
            connected = true;
            System.out.println("Connection accepted \n");

            InputStream inputstreamconsola = System.in;
            InputStreamReader inputstreamreaderconsola = new InputStreamReader(
                    inputstreamconsola);
            BufferedReader bufferedreaderconsola = new BufferedReader(
                    inputstreamreaderconsola);

            in = new DataInputStream(sslsocket.getInputStream());
            out = new DataOutputStream(sslsocket.getOutputStream());

 SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
          sslsocket = (SSLSocket) sslsocketfactory.createSocket("localhost", 9999);
          in = new DataInputStream(sslsocket.getInputStream());
          out = new DataOutputStream(sslsocket.getOutputStream());

我遇到的问题是，当我想将字节[]从服务器传递到客户端时，字节[]在服务器中具有正确的值，但它以空值到达客户端。 注意：当我使用readUTF（）和writeUTF（）传递字符串时，值​​发送和接收正确

在这种情况下会出现“错误”：

服务器：

     byte[] nonceBytes = new byte[(int) 8];
     nonce = System.currentTimeMillis();
     nonceBytes = longToByteArray(nonce);

    System.out.print("\nNonce gerado: ");
        for (int i = 0; i < 8; i++)
         System.out.print(getHexString(nonceBytes[i]));
    System.out.print("\n");
            out.writeUTF("pass#");
    out.write(nonceBytes, (int) 0, nonceBytes.length); VALUE HERE IS CORRECT

我想了解为什么我不能通过out.write（）方法发送字节[]，并通过in.read（）方法将其放入客户端。

您忽略了由

read（）返回的结果。

您不能假设它填充了缓冲区。在这种情况下，您可能应该使用

DataInputStream.readFully（）

请注意，此问题与SSL无关。

但是read（）返回的结果会在客户端和使用后保存到nbytes中。我不明白的是，非字节从服务器中的write（）得到空值的原因。您的建议在EJP中起作用，但我想了解为什么read（）不起作用。。不管怎样，非常感谢你。这很有效。它只是不做你认为它做的。这不是一回事。请参阅Javadoc。它没有说它在任何地方填满了缓冲区。恰恰相反，它用了相当长的篇幅来解释它可能不是。。好的，我看到了javadoc，我想我明白了。再次感谢您EJP。但是read（）返回的结果会在客户端和使用后保存到N字节中。我不明白的是，非字节从服务器中的write（）得到空值的原因。您的建议在EJP中起作用，但我想了解为什么read（）不起作用。。不管怎样，非常感谢你。这很有效。它只是不做你认为它做的。这不是一回事。请参阅Javadoc。它没有说它在任何地方填满了缓冲区。恰恰相反，它用了相当长的篇幅来解释它可能不是。。好的，我看到了javadoc，我想我明白了。再次感谢你，EJP。
