Java 插座保持打开状态时打印BufferedReader
我想要的只是从wunderground打印到控制台的响应:Java 插座保持打开状态时打印BufferedReader,java,sockets,tcp,io,telnet,Java,Sockets,Tcp,Io,Telnet,我想要的只是从wunderground打印到控制台的响应: public class Weather { public static void main(String[] args) { String host = "rainmaker.wunderground.com"; int port = 3000; int c; { try (Socket socket = new Socket(host,
public class Weather {
public static void main(String[] args) {
String host = "rainmaker.wunderground.com";
int port = 3000;
int c;
{
try (Socket socket = new Socket(host, port);
PrintWriter printWriter = new PrintWriter(socket.getOutputStream(), true);
final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in))) {
while (true) {
System.out.println(socket.toString());
c = bufferedReader.read();
System.out.print((char) c);
}
} catch (IOException ex) {
System.out.println(ex + host + port);
System.exit(1);
} finally {
System.exit(1);
}
}
}
}
但是,没有太多的输出可以继续:

从CLI运行telnet,连接正常。我发现一些旧代码:
public class InputOutput extends Observable {
private static final Logger log = Logger.getLogger(InputOutput.class.getName());
private Alias alias = new Alias();
public InputOutput() {
}
private void readFromConsole(final OutputStream outputStream) {
Thread read = new Thread() {
@Override
public void run() {
String line;
byte[] bytes;
Scanner scanner;
while (true) {
GameDataBean gameData = null;
scanner = new Scanner(System.in);
line = scanner.nextLine();
try {
gameData = alias.parseUserInput(line);
} catch (StringIndexOutOfBoundsException e) {
log.fine(e.toString());
}
if (gameData != null) {
setChanged();
notifyObservers(gameData);
} else {
bytes = line.getBytes();
try {
outputStream.write(bytes);
outputStream.write(10);
outputStream.flush();
} catch (IOException ex) {
log.fine(ex.toString());
}
}
}
}
};
read.start();
}
private void readInput(final InputStream inputStream) throws FileNotFoundException, IOException {
Thread readInput = new Thread() {
@Override
public void run() {
char ch = 0;
int intVal = 0;
StringBuilder sb = new StringBuilder();
try {
while ((intVal = inputStream.read()) != -1) {
ch = (char) intVal;
printToConsole(ch);
//logToFile(ch);
sb.append(ch);
if (intVal == 13) {
setChanged();
notifyObservers(sb.toString());
sb = new StringBuilder();
}
}
} catch (IOException ex) {
Logger.getLogger(InputOutput.class.getName()).log(Level.SEVERE, null, ex);
}
}
private void logToFile(char c) throws IOException {
String fname = "weather.log";
File f = new File(fname);
f.createNewFile();
try (PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(fname, true)))) {
out.print(c);
out.flush();
}
}
private void printToConsole(char c) {
System.out.print(c);
}
};
readInput.start();
}
public void readWriteParse(final InputStream inputStream, final OutputStream outputStream) throws FileNotFoundException, IOException {
readFromConsole(outputStream);
readInput(inputStream);
}
}
我认为,当套接字仍然打开时,它必须是多线程的,我记得。为了澄清这一点,我想在不关闭套接字的情况下打印输出。看见
