我最近开始学习套接字和其他网络东西这样的工作,我用GUI做了一个简单的聊天程序,它有点工作,问题是如果命令消息发送到服务器客户端必须放相同消息两次,如果服务器发送消息,客户端必须回复一次。
继承我的客户端/服务器类:
package org.codingllamas.Chat;
import java.io.*;
import java.net.*;
import javax.swing.text.BadLocationException;
import javax.swing.text.html.HTML;
public class SC {
static Socket clientSocket;
static BufferedReader inFromServer;
static DataOutputStream outToServer;
public static void clientSetup(int port,String ip) throws IOException, BadLocationException {
String modifiedSentence;
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>Connected to </b>" + ip + ":" + port + "<br>",0,0,HTML.Tag.B);
while (true) {
///BufferedReader inFromUser = new BufferedReader( new InputStreamReader(System.in));
clientSocket = new Socket(ip,port);
outToServer = new DataOutputStream(clientSocket.getOutputStream());
inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
modifiedSentence = inFromServer.readLine();
//System.out.println(modifiedSentence);
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>Server: </b>" + modifiedSentence + "<br>",0,0,HTML.Tag.B);
//clientSocket.close();
}
}
public static void clientSend(String msg) throws IOException, BadLocationException{
outToServer.writeBytes(msg + "\r");
outToServer.flush();
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>You: </b>" + msg + "<br>",0,0,HTML.Tag.B);
}
static ServerSocket welcomeSocket;
static Socket connectionSocket;
static BufferedReader inFromClient;
static DataOutputStream outToClient;
public static void serverSetup(int port) throws Exception {
String clientSentence;
welcomeSocket = new ServerSocket(port);
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>Server Started on port: " + port + "</b><br>",0,0,HTML.Tag.B);
while(true){
connectionSocket = welcomeSocket.accept();
inFromClient = new BufferedReader(new InputStreamReader(connectionSocket.getInputStream()));
clientSentence = inFromClient.readLine();
outToClient = new DataOutputStream(connectionSocket.getOutputStream());
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>Parther: </b>" + inFromClient.readLine() + "<br>",0,0,HTML.Tag.B);
}
}
public static void serverSend(String msg) throws IOException, BadLocationException {
//DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());
outToClient.writeBytes(msg + "\r");
outToClient.flush();
Start.kit.insertHTML(Start.doc,Start.doc.getLength(),"<b>You: </b>" + msg + "<br>",0,0,HTML.Tag.B);
}
}

答案 0 :(得分:1)
DataOutputStream
,请使用BufferedWriter.
modifiedSentence?
创建一个新套接字:在客户端的生命周期中使用单个Socket
,并循环读取行,并在获得null时关闭套接字。accept():
不要从客户端读取一行,启动一个新线程来读取客户端现在所做的行。
