Question

我正在尝试在java中的套接字服务器和php客户端之间创建通信，但显然没有数据从服务器发送到客户端。我已经尝试了很多方法来将数据写入套接字但是这些方法都没有工作，尽管我能够将数据从客户端发送到服务器。

服务器端代码

int port = 5566, maxConnections = 0;
int nrCon=0;

ServerSocket listener = new ServerSocket(port);
Socket server;

while((nrCon++<maxConnections)|| (maxConnections ==0)){
    server = listener.accept();
    BufferedReader in = new BufferedReader (new InputStreamReader(server.getInputStream()));
    BufferedWriter out = new BufferedWriter( new OutputStreamWriter( server.getOutputStream() ) );
    //PrintWriter out = new PrintWriter(server.getOutputStream(), true); 
    //ObjectOutputStream oos = new ObjectOutputStream(server.getOutputStream());
    //DataOutputStream os = new DataOutputStream(server.getOutputStream());

    String line, data="";
    while((line = in.readLine())!= null ){

        System.out.println("wowowoowow");
        data = data + line;
        String[] coords = data.split(" ");
    }

    out.print("ROUTE DIJKSTRA: \n");
    //out.flush();
    //os.writeUTF("testetstets");

客户端代码

$PORT = 5566;
$HOST = "localhost";

$sock = socket_create(AF_INET, SOCK_STREAM, 0)
or die("error: could not create socket\n");

$succ = socket_connect($sock, $HOST, $PORT) 
or die("error: could not connect to host\n");
socket_set_nonblock($sock);

if ( $_POST['v_lat']=="undefined"  && $_POST['v_lng']=="undefined" ){
    $text = "$sLng $sLat $dLng $dLat";
}else{
    $vLat = $_POST['v_lat'];
    $vLng = $_POST['v_lng'];
    $text = "$sLng $sLat $vLng $vLat $dLng $dLat";
}

$sent = socket_write($sock, $text, strlen($text)+1);
$sock_err = socket_last_error($sock);
if ($sent === false) {
    echo "could not send data to server\n";
    break;
}else {
    echo "sent ".$sent." bytes\n";
}
echo "sock error send: ".$sock_err." \n";

$result = socket_read ($sock, 2048);
$sock_err = socket_last_error($sock);
echo "sock err: ".$sock_err." \n";
echo "Reply From Server  :".$result;

我从sock_err调用得到的是错误代码10035，无论我尝试多少套接字写入数据方法，服务器显然都不会发送数据。我没有想法了。

套接字服务器不向php客户端发送数据
