TCP/IP Sending request and getting response
提问by Sandip Armal Patil
I am Working on TCP/IPin Java. First, I read TCP/IPand understand how it's working.
What i Need:-
Ok, Now i want to implement it in java. I am trying to Send some input in request to specific port/IPfrom my IP. and need to get response.
I don't understand how to implement it.
Here is my Input:
我TCP/IP在 Java 中工作。首先，我阅读TCP/IP并理解它是如何工作的。
我需要什么：-
好的，现在我想在 Java 中实现它。我正在尝试port/IP从我的 IP向特定请求发送一些输入。并且需要得到回应。
我不明白如何实现它。
这是我的输入：
Destination IP
Destination Port
Input(String or Anything)
Here is my code which i use for Client.
这是我用于客户端的代码。
try {
socket = new Socket("localhost", port);
}
catch(Exception e) {
System.out.println("Error connectiong to server:" + e);
return;
}
System.out.println("Connection accepted " +
socket.getInetAddress() + ":" +
socket.getPort());
/* Creating both Data Stream */
try
{
Sinput = new ObjectInputStream(socket.getInputStream());
Soutput = new ObjectOutputStream(socket.getOutputStream());
}
catch (IOException e) {
System.out.println("Exception creating new Input/output Streams: " + e);
return;
}
// now that I have my connection
String test = "aBcDeFgHiJkLmNoPqRsTuVwXyZ";
// send the string to the server
System.out.println("Client sending \"" + test + "\" to serveur");
try {
Soutput.writeObject(test);
Soutput.flush();
}
catch(IOException e) {
System.out.println("Error writting to the socket: " + e);
return;
}
// read back the answer from the server
String response;
try {
response = (String) Sinput.readObject();
System.out.println("Read back from server: " + response);
}
catch(Exception e) {
System.out.println("Problem reading back from server: " + e);
}
try{
Sinput.close();
Soutput.close();
}
Please give me some hint or reference.
请给我一些提示或参考。

Creating Scoketgo through this will help you. if you are implementing Sockets, you need to use ServerSocket class to create the ServerSocket . Then Socket class to request the create the connection between Client and Sever.
通过这个创建 Scoket会对你有所帮助。如果您正在实现 Sockets，则需要使用 ServerSocket 类来创建 ServerSocket 。然后 Socket 类请求在 Client 和 Sever 之间建立连接。
