使用Java中的套接字編程將數據流從客戶端程序（在VM中運行）發送到服務器程序（在Host OS上）

Question

客戶端套接字程序（在Windows VM中）根據以下代碼生成1到10的整數

public class ClientSocket {

    public static void main(String[] args)

    {

try{
    InetAddress inetAddress = InetAddress.getLocalHost();
    String clientIP = inetAddress.getHostAddress();
    System.out.println("Client IP address " + clientIP);

   Integer dataSendingPort ;
   dataSendingPort = 6999 ;

    Socket socket = new Socket("192.168.0.32",dataSendingPort);
    String WelcomeMessage = " hello server from " + clientIP ;


 BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));

 if(socket.isConnected()){
     System.out.println("connection was successful");
 }
 else{
     System.out.println("Error- connection was not successful");
 }


 for (int x= 0 ; x< 10 ; x++){
     bufferedWriter.write(x);
     bufferedWriter.flush();
 }

    bufferedWriter.close();
}
catch (IOException e){
    System.out.println(e);
}// catch
        finally{

    System.out.println("closing connection");

}

    } // main

} // class

我的服務器套接字程序在Mac OS上作為主機運行，其代碼如下所示

 public class MyServer {

        public static void main(String[] args) throws Exception {


           try {
// get input data by connecting to the socket


                InetAddress inetAddress = InetAddress.getLocalHost();
                String ServerIP = inetAddress.getHostAddress();

               System.out.println("\n server IP address = " + ServerIP);

               Integer ListeningPort ;
               ListeningPort = 6999 ;

               ServerSocket serverSocket = new ServerSocket(ListeningPort);

               System.out.println("server is receiving data on port # "+ ListeningPort +"\n");

               // waiting for connection form client

               Socket socket = serverSocket.accept();


               if(socket.isConnected()){

                   System.out.println("Connection was successful");
               }
               else {
                   System.out.println("connection was not successful");
               }



              BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));

    Integer s = 0 ;

       while (( s = input.read()) >= 0){

           System.out.println(input.read());
       }
           } //try

            catch (IOException e)
            {
                System.out.println(e);

            } // catch


        } //main
    } //socket class

問題是，當我使用while循環並不使用循環而接收第一個值（即0）時，我正在接收的輸出為-1。

但是，我能夠從客戶端向服務器發送單個值，但是如何從客戶端發送值流並將其打印在服務器端。

歡迎建議

Answer 1

• -1表示流結束。
• 關閉股票的輸入或輸出流會關閉套接字。
• 在測試時， socket.isConnected()不能為假。
• input.ready()並不是測試流的末尾，消息的末尾，傳輸的末尾或任何真正有用的測試。
• 不要沖洗內部循環。
