我收到“套接字写入错误”。在 StackOverflow 上搜索时，我发现了一些使用 flush(); 的建议。通过流发送字节的方法。我遇到的问题是在使用 flush(); 方法，我仍然得到错误。我不确定是什么导致了问题。有任何想法吗？这是完整的客户端代码：
import java.io.*;
import java.net.*;
import java.util.ArrayList;
import java.util.Scanner;
public class TCPClient {
public static void main(String[] args) throws Exception {
String origSentence;
String modifiedSentence;
boolean win = false;
boolean lose = false;
//BufferedReader inFromUser;
//inFromUser = new BufferedReader(new InputStreamReader(System.in));
Scanner inFromUser = new Scanner(System.in);
Socket clientSocket = new Socket("10.64.121.145", 6784);
boolean first = true;
DataOutputStream outToServer =
new DataOutputStream(clientSocket.getOutputStream());
origSentence = inFromUser.nextLine();
outToServer.writeBytes(origSentence + '\n');
outToServer.flush();
Scanner inFromServer = new Scanner(clientSocket.getInputStream());
modifiedSentence = inFromServer.nextLine();
GUI gui = new GUI(Integer.parseInt(modifiedSentence));
System.out.println("The word is " + modifiedSentence + " letters long. Pick a letter!");
gui.isNotSolved();
while (win != true && lose != true) {
origSentence = inFromUser.nextLine();
System.out.println(origSentence);
outToServer.writeBytes(origSentence + '\n'); //The failure is on this line
outToServer.flush();
modifiedSentence = inFromServer.nextLine();
if (modifiedSentence.equals(""))//guess not in word so add a miss
{
if (gui.addMiss(origSentence) == false) {
lose = true;
}
}
if (!modifiedSentence.equals(""))//guess is in word so display where letter occurs
{
ArrayList<Character> list = new ArrayList<Character>();
int length = modifiedSentence.length();
for (int i = 0; i < length; i++) {
list.add(modifiedSentence.charAt(i));
}
for (char c : list) {
if (c == ' ') {
list.remove(c);
}
}
for (int i = 0; i < list.size(); i++) {
String s = list.get(i).toString();
gui.addLetter(origSentence.charAt(0), Integer.parseInt(s));
}
}
if (gui.isNotSolved() == false)//game won send server "won" message to terminate connection
{
String won = "won";
outToServer.writeBytes(won);
outToServer.flush();
}
if (lose == true)//game lost send server "lost" message to
{ //have server send the word to display for player
String lost = "lost";
outToServer.writeBytes(lost);
gui.setWord(modifiedSentence);
outToServer.flush();
}
}
clientSocket.close();
}
}
...代码继续，但它似乎并没有进入其余的代码。我有点迷茫为什么它总是失败。我在第一次使用 outToServer 后刷新（），但在第二次使用时失败。我猜这是一个客户端问题。有什么帮助吗？谢谢。这是服务器代码：
import java.io.*;
import java.net.*;
import java.util.Scanner;
public class TCPServer {
public static void main(String[] args) throws Exception {
String clientSentence;
Word word = new Word();
int wordLen = word.getLength();
ServerSocket welcomeSocket = new ServerSocket(6784);
System.out.println(InetAddress.getLocalHost());
boolean begin = true;
while (true) {
Socket connSocket = welcomeSocket.accept();
Scanner inFromClient = new Scanner(connSocket.getInputStream());
clientSentence = inFromClient.nextLine(); //cap would go after this
DataOutputStream outToClient =
new DataOutputStream(connSocket.getOutputStream());
if (begin == true) {
//DataOutputStream outToClient =
//new DataOutputStream(connSocket.getOutputStream());
System.out.println("begin " + word.getWord());
outToClient.writeBytes("" + word.getLength());
outToClient.flush();
}
if (begin == false) {
System.out.println("hello");
//DataOutputStream outToClient =
//new DataOutputStream(connSocket.getOutputStream());
String pos = word.getSpots(clientSentence.charAt(0));
outToClient.writeBytes(pos);
outToClient.flush();
}
if (clientSentence.equals("lost")) {
outToClient.writeBytes(word.getWord());
outToClient.flush();
}
if (clientSentence.equals("won")) {
connSocket.close();
}
begin = false;
connSocket.close();
}
}
}
这是错误：
