我想在Java中的SocketServer(服務器)和php中的Socket(客戶端)之間建立通信。 客戶端能夠連接到主機,客戶端能夠發送消息並且服務器成功讀取消息。但問題出現時,套接字服務器寫入客戶端,客戶端不接收來自服務器的消息。SocketServer在java服務器和php客戶端之間的通信
我已經讀過關於同一場景(java-php套接字通信)的其他問題,但我似乎無法找到導致問題的原因。
如果我使用Java Socket作爲客戶端,那麼通信在兩種方式中都可以完美地工作。
服務器:
import java.io.*;
import java.net.ServerSocket;
import java.net.Socket;
public class Server {
protected ServerSocket socket;
protected final int port = 9005;
protected Socket connection;
protected String command = new String();
protected String responseString = new String();
public void init(){
System.out.println("Launching Server: ");
try{
socket = new ServerSocket(port);
while(true)
{
// open socket
connection = socket.accept();
System.out.println("Client Connected ");
// get input reader
InputStreamReader inputStream = new InputStreamReader(connection.getInputStream());
BufferedReader input = new BufferedReader(inputStream);
// get input
command = input.readLine();
// process input
System.out.println("Command: " + command);
responseString = command + " MC2 It Works!";
// get output handler
PrintStream response = new PrintStream(connection.getOutputStream());
// send response
response.println(responseString);
}
}
catch (IOException e){
e.printStackTrace();
}
}
}
客戶:
class Client {
private $address;
private $port;
public function __construct($address, $port){
$this->address = $address;
$this->port = $port;
$this->init();
}
private function init(){
//create socket
if(! $socket = socket_create(AF_INET, SOCK_STREAM, getprotobyname('tcp'))){
$this->showError("socket create");
};
//establish connection
socket_connect($socket, $this->address, $this->port);
//write to server
$message = "I am a client";
socket_write($socket, $message, strlen($message)); //Send data
echo "Listening to Server\n";
//read from server
if(!$reponse = socket_read($socket, 2048, PHP_NORMAL_READ)){
$this->showError("socket read");
}
//print response
echo "Response from server------------------\n";
echo $reponse;
socket_close($socket);
}
private function showError($message){
echo ("Error: ".$message);
exit(666);
}
}
$address="localhost";$port=9005;
echo "Testing Client Server\n";
$client = new Client($address, $port);
可能有人請指引我可能是什麼問題就在這裏?
謝謝奧茲根,那就是問題!服務器正在尋找最終線路! – 2015-04-06 10:36:33
