是的,我确实看过 sun 上的教程,但它们对我没有帮助,只传输了第一个命令。
我有一个方法
public void openConnection() throws IOException{
serverSocket = new ServerSocket(5346);
Socket simSocket = serverSocket.accept();
is = simSocket.getInputStream();
os = simSocket.getOutputStream();
writer = new PrintWriter(os);
isReader = new InputStreamReader(is);
reader = new BufferedReader(isReader);
System.out.println("Connection succesfull.");
}
和
public void sendTo(int command) {
try {
writer.println(command);
writer.flush();
} catch(Exception e) {
System.out.println("Error sending command to the robot");
System.out.println(e.toString());
}
}
在发送方,并且
public static void setUpConnection() {
try {
socket = new Socket(InetAddress.getLocalHost(), 5346);
is = new InputStreamReader(
socket.getInputStream());
reader = new BufferedReader(is);
writer = new PrintWriter(socket.getOutputStream());
System.out.println("Simulator: connection succesful");
} catch (IOException e) {
e.printStackTrace();
}
}
和
while (true) {
intCommand = reader.read();
ett = reader.readLine(); // does nothing, but without this line it doesn't work
command = (char) intCommand;
在接收端。它可以完美地发送一个字符或一个字符的ASCII码。我需要更改此代码以发送整数或仅发送字节数组而不是字符。如果我只留下 InputStream 和 OutputStream 它确实接收到第一个命令,仅此而已,而这些方法不断接收通过 sendTo 发送的内容。即使在套接字文档中,它们也只有发送字符的示例。
