我有兩個程序,我希望他們連接到我的學校服務器afs1.njit.edu,但它永遠不會連接。那是我擁有這些文件的地方。我應該運行兩個ssh程序來運行不同的程序嗎?不確定如何測試它們。 (這些是我在編寫代碼之前想要測試的來自在線的一個簡單例子)我將它們編譯爲serperately並且它們從不連接。如何在ssh上測試客戶端和服務器程序?
singleSocketserver.java
public static void main(String[] args) {
try{
socket1 = new ServerSocket(port);
System.out.println("SingleSocketServer Initialized");
int character;
while (true) {
connection = socket1.accept();
BufferedInputStream is = new BufferedInputStream(connection.getInputStream());
InputStreamReader isr = new InputStreamReader(is);
process = new StringBuffer();
while((character = isr.read()) != 13) {
process.append((char)character);
}
System.out.println(process);
//need to wait 10 seconds for the app to update database
try {
Thread.sleep(10000);
}
catch (Exception e){}
TimeStamp = new java.util.Date().toString();
String returnCode = "SingleSocketServer repsonded at "+ TimeStamp + (char) 13;
BufferedOutputStream os = new BufferedOutputStream(connection.getOutputStream());
OutputStreamWriter osw = new OutputStreamWriter(os, "US-ASCII");
osw.write(returnCode);
osw.flush();
}
}
catch (IOException e) {}
try {
connection.close();
}
catch (IOException e) {}
}
}
SocketClient.java
public class SocketClient {
public static void main(String[] args) {
/** Define a host server */
String host = "afs1.njit.edu";
/** Define a port */
int port = 19999;
StringBuffer instr = new StringBuffer();
String TimeStamp;
System.out.println("SocketClient initialized");
try {
/** Obtain an address object of the server */
InetAddress address = InetAddress.getByName(host);
/** Establish a socket connetion */
Socket connection = new Socket(address, port);
/** Instantiate a BufferedOutputStream object */
BufferedOutputStream bos = new BufferedOutputStream(connection.
getOutputStream());
/** Instantiate an OutputStreamWriter object with the optional character
* encoding.
*/
OutputStreamWriter osw = new OutputStreamWriter(bos, "US-ASCII");
TimeStamp = new java.util.Date().toString();
String process = "Calling the Socket Server on "+ host + " port " + port +
" at " + TimeStamp + (char) 13;
/** Write across the socket connection and flush the buffer */
osw.write(process);
osw.flush();
/** Instantiate a BufferedInputStream object for reading
/** Instantiate a BufferedInputStream object for reading
* incoming socket streams.
*/
BufferedInputStream bis = new BufferedInputStream(connection.
getInputStream());
/**Instantiate an InputStreamReader with the optional
* character encoding.
*/
InputStreamReader isr = new InputStreamReader(bis, "US-ASCII");
/**Read the socket's InputStream and append to a StringBuffer */
int c;
while ((c = isr.read()) != 13)
instr.append((char) c);
/** Close the socket connection. */
connection.close();
System.out.println(instr);
}
catch (IOException f) {
System.out.println("IOException: " + f);
}
catch (Exception g) {
System.out.println("Exception: " + g);
}
}
}
就是這樣,2個相同的服務器謝謝你 – 2014-10-20 14:44:05
