从Flex（XMLSocket）到.NET（Socket）连接的数据问题 [英] Data issue connecting from Flex (XMLSocket) to .NET (Socket)
本文介绍了从Flex（XMLSocket）到.NET（Socket）连接的数据问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
因此，我已经成功地将它们连接在一起使用Flex上的XMLSocket和服务器端的Socket，客户端获取连接的事件，正确地发送数据，但是当我尝试从服务器发回数据客户端没有任何反应（即使BeginSend回调显示整个缓冲区已经发送）。
客户端：
private var hostName：String =localhost;
private var port：uint = 4444;
private var socket：XMLSocket;
public var app：DotNETServerTest;
公共函数DotNetSocketExample（）{
socket = new XMLSocket（）;
configureListeners（socket）;
socket.connect（hostName，port）;
public function send（data：Object）：void {
socket.send（data）;
public function disconnect（）：void {
socket.close（）;
closeHandler（null）;
private function configureListeners（dispatcher：IEventDispatcher）：void {
dispatcher.addEventListener（Event.CLOSE，closeHandler）;
dispatcher.addEventListener（Event.CONNECT，connectHandler）;
dispatcher.addEventListener（DataEvent.DATA，dataHandler）;
private function closeHandler（event：Event）：void {
trace（closeHandler：+ event）;
app.send_btn.enabled = false;
app.disconnect_btn.enabled = false;
private function connectHandler（event：Event）：void {
trace（connectHandler：+ event）;
app.send_btn.enabled = true;
app.disconnect_btn.enabled = true;
private function dataHandler（event：DataEvent）：void {
trace（dataHandler：+ event）;
Alert.show（event.data）;
$ b 服务器（仅限特定部分）：
//这是回调函数，将在客户端连接时调用
public static void OnClientConnect（IAsyncResult asyn）
{
try
{
SocketClient NewConnection = new SocketClient（SocketServer.EndAccept（asyn））;
//这是我试图发送
SendMessageTo（NewConnection，< test>< / test>）的测试消息;
Clients.Add（NewConnection）;
WaitForData（NewConnection）;
LogMessage（NewConnection，Client＃{0} connected，Clients.Count）;
SocketServer.BeginAccept（new AsyncCallback（OnClientConnect），null）;
catch（ObjectDisposedException）
{
LogMessage（OnClientConnection：Socket has been closed。）;
}
catch（SocketException se）
{
Console.WriteLine（se.Message）;
内部静态无效SendMessageTo（SocketClient客户端，字符串数据）
{
byte [] byteData = Encoding.ASCII.GetBytes ）;
SendMessageTo（client，byteData）;
内部静态无效SendMessageTo（SocketClient客户端，字节[] byteData）
{
尝试
{
client.socket.BeginSend （byteData，0，byteData.Length，SocketFlags.None，新的AsyncCallback（SendCallback），客户端）;
}
catch（Exception e）
{
LogMessage（客户端，发送数据到客户端时出错：{0}，e.Message）;
内部静态无效SendCallback（IAsyncResult ar）
{
//从异步状态对象中检索套接字。
SocketClient处理程序=（SocketClient）ar.AsyncState;
try
{
int bytesSent = handler.socket.EndSend（ar）;
catch（Exception e）
{
LogMessage（handler，e.Message）;

$ b $ p请帮忙！
谢谢，Ron
解决方案发现问题 - 我没有发送\0在每个
改变了这个： .ASCII.GetBytes（数据）;
client.socket.BeginSend（byteData，0，byteData.Length，SocketFlags.None，new AsyncCallback（SendCallback），client）;
至此：
byte [] byteData = Encoding.ASCII.GetBytes（Data +\0）;
client.socket.BeginSend（byteData，0，byteData.Length，SocketFlags.None，new AsyncCallback（SendCallback），client）;
I'm working on a chat/IM system for my game (which is written in Flex) and wanted to connect it to my server (which is written in C#) via sockets.
So, I've successfully connected them together using XMLSocket on Flex, and Socket on the server side, the client gets a connected event, sends data correctly, but when I try to send back data from the server to the client, nothing happens (even though the BeginSend callback shows that the entire buffer was sent).
Client:
private var hostName:String = "localhost";
private var port:uint = 4444;
private var socket:XMLSocket;
public var app:DotNETServerTest;
public function DotNetSocketExample() {
socket = new XMLSocket();
configureListeners(socket);
socket.connect(hostName, port);
}
public function send(data:Object):void {
socket.send(data);
}
public function disconnect():void {
socket.close();
closeHandler(null);
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.CLOSE, closeHandler);
dispatcher.addEventListener(Event.CONNECT, connectHandler);
dispatcher.addEventListener(DataEvent.DATA, dataHandler);
}
private function closeHandler(event:Event):void {
trace("closeHandler: " + event);
app.send_btn.enabled = false;
app.disconnect_btn.enabled = false;
}
private function connectHandler(event:Event):void {
trace("connectHandler: " + event);
app.send_btn.enabled = true;
app.disconnect_btn.enabled = true;
}
private function dataHandler(event:DataEvent):void {
trace("dataHandler: " + event);
Alert.show(event.data);
}
Server (Only specific parts):
// This is the call back function, which will be invoked when a client is connected
public static void OnClientConnect(IAsyncResult asyn)
{
try
{
SocketClient NewConnection = new SocketClient(SocketServer.EndAccept(asyn));
// This is a test message I'm attempting to send
SendMessageTo(NewConnection, "<test></test>");
Clients.Add(NewConnection);
WaitForData(NewConnection);
LogMessage(NewConnection, "Client # {0} connected", Clients.Count);
SocketServer.BeginAccept(new AsyncCallback(OnClientConnect), null);
}
catch (ObjectDisposedException)
{
LogMessage("OnClientConnection: Socket has been closed.");
}
catch (SocketException se)
{
Console.WriteLine(se.Message);
}
}
internal static void SendMessageTo(SocketClient client, string Data)
{
byte[] byteData = Encoding.ASCII.GetBytes(Data);
SendMessageTo(client, byteData);
}
internal static void SendMessageTo(SocketClient client, byte[] byteData)
{
try
{
client.socket.BeginSend(byteData, 0, byteData.Length, SocketFlags.None, new AsyncCallback(SendCallback), client);
}
catch (Exception e)
{
LogMessage(client, "Error sending data to client: {0}", e.Message);
}
}
internal static void SendCallback(IAsyncResult ar)
{
// Retrieve the socket from the async state object.
SocketClient handler = (SocketClient)ar.AsyncState;
try
{
int bytesSent = handler.socket.EndSend(ar);
}
catch (Exception e)
{
LogMessage(handler, e.Message);
}
}
Please help!
Thanks, Ron
解决方案 Found the problem - I didn't send out \0 at the end of each send.
Changed this:
byte[] byteData = Encoding.ASCII.GetBytes(Data);
client.socket.BeginSend(byteData, 0, byteData.Length, SocketFlags.None, new AsyncCallback(SendCallback), client);
To this:
byte[] byteData = Encoding.ASCII.GetBytes(Data + "\0");
client.socket.BeginSend(byteData, 0, byteData.Length, SocketFlags.None, new AsyncCallback(SendCallback), client);
