我弄清楚了问题所在,但现在我遇到了另一个问题。我想从另一台 PC 远程控制一台 PC,那部分工作,但你必须转发端口。是否可以像 TeamViewer 一样连接?所以我绕过防火墙并且不必转发端口?如果是,如何?如果有人能帮助我,那就太棒了:)

我编写了一个代码,这样您就可以从另一台计算机控制一台计算机。唯一的问题是它不适用于您自己网络之外的计算机(也许我连接了错误的 IP?我尝试了那个人的 IPv4 和来自 WhatIsMyIP 的 IP)。我怎样才能使它适用于我的网络外部?

这是服务器类(我删除了很多代码,因为它没有意义)

    public partial class Form1 : Form
{
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(long dwFlags, long dx, long dy, long cButtons, long dwExtraInfo);

private const int MOUSE_LEFTDOWN = 0x02;
private const int MOUSE_LEFTUP = 0x04;
private const int MOUSE_RIGTDOWN = 0x08;
private const int MOUSE_RIGHTUP = 0x10;

private TcpListener listener;
private Socket mainSocket;
private int port;
private Stream s;
private Thread eventWatcher;
private int imageDelay;
string connString;
string connToString;
string db;
MySqlCommand command;
MySqlCommand command2;
MySqlCommand command3;
MySqlCommand command4;

MySqlConnection connection = null;

public Form1()
{
InitializeComponent();
port = 1338;
imageDelay = 1000;
}
public Form1(int p)
{
port = p;
imageDelay = 1000;
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
MessageBox.Show(getIP());
startConnection();

command = connection.CreateCommand();
command2 = connection.CreateCommand();
command3 = connection.CreateCommand();
command4 = connection.CreateCommand();
MessageBox.Show(connString);
MessageBox.Show(db);

this.Hide();
port = 1338;
while (true)
{
try
{
startListening();
}
catch (Exception)
{
}
}
}

public void startListening()
{
try
{
listener = new TcpListener(port);
listener.Start();
mainSocket = listener.AcceptSocket();
s = new NetworkStream(mainSocket);
eventWatcher = new Thread(new ThreadStart(waitForKeys));
eventWatcher.Start();
while (true)
{
Bitmap screeny = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb);
Graphics theShot = Graphics.FromImage(screeny);
theShot.ScaleTransform(.25F, .25F);
theShot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);
BinaryFormatter bFormat = new BinaryFormatter();
bFormat.Serialize(s, screeny);
Thread.Sleep(imageDelay);
theShot.Dispose();
screeny.Dispose();
}
}
catch (Exception)
{
if (mainSocket.IsBound)
mainSocket.Close();
if (listener != null)
listener.Stop();
}
}

private static void trigger(IAsyncResult i) { }

和客户端代码(同样,删除了很多):

    public class StateObject
{
public Socket workSocket = null;
public const int BufferSize = 256;
public byte[] buffer = new byte[BufferSize];
public StringBuilder sb = new StringBuilder();
}

public partial class Form2 : Form
{
private static string response;

private Stream stream;
private StreamWriter eventSender;
private Thread theThread;
private TcpClient client;
private Form1 mForm;
private int resolutionX;
private int resolutionY;
//private int sendDelay = 250;
//private Thread delayThread;
public bool sendKeysAndMouse = false;

private static ManualResetEvent sendDone = new ManualResetEvent(false);
private static ManualResetEvent receiveDone = new ManualResetEvent(false);

public Form2()
{
InitializeComponent();
}
public Form2(TcpClient s, Form1 callingForm)
{
client = s;
mForm = callingForm;
InitializeComponent();
theThread = new Thread(new ThreadStart(startRead));
theThread.Start();
}

private void Form2_FormClosed(object sender, FormClosedEventArgs e)
{
if (theThread.IsAlive)
theThread.Abort();
mForm.form2Closed();
}
private void startRead()
{
try
{
stream = client.GetStream();
eventSender = new StreamWriter(stream);
while (true)
{
BinaryFormatter bFormat = new BinaryFormatter();
Bitmap inImage = bFormat.Deserialize(stream) as Bitmap;
resolutionX = inImage.Width;
resolutionY = inImage.Height;
theImage.Image = (Image)inImage;
}
}
catch (Exception) { }
/*try
{
Image theDesktop;
stream = client.GetStream();
theDesktop.Save(stream,new ImageFormat(
while (true)
{
while (stream.Read(buffer, 0, 1024) > 0)
theDesktop.Read(buffer, 0, 1024);
if(theDesktop != null) {
theDesktop.
theImage.Image = temp;
}
}
catch (Exception gay) { }*/
}

private void Form2_ResizeEnd(object sender, EventArgs e)
{

}

private void Form2_Load(object sender, EventArgs e)
{

}


private void Form2_MouseMove(object sender, MouseEventArgs e)
{
}


private void theImage_MouseClick(object sender, MouseEventArgs e)
{
if (!sendKeysAndMouse)
return;
eventSender.Write("LCLICK\n");
eventSender.Flush();
}

private void theImage_MouseDown(object sender, MouseEventArgs e)
{
if (!sendKeysAndMouse)
return;
eventSender.Write("LDOWN\n");
eventSender.Flush();
}

private void theImage_MouseUp(object sender, MouseEventArgs e)
{
if (!sendKeysAndMouse)
return;
eventSender.Write("LUP\n");
eventSender.Flush();
}

private void Receive(Socket client)
{
try
{
StateObject state = new StateObject();
state.workSocket = client;

client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state);
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}

private void Send(Socket client, String data)
{
byte[] byteData = Encoding.ASCII.GetBytes(data);

client.BeginSend(byteData, 0, byteData.Length, 0, new AsyncCallback(SendCallback), client);
}

private void ReceiveCallback(IAsyncResult ar)
{
try
{
StateObject state = (StateObject)ar.AsyncState;
Socket client = state.workSocket;

int bytesRead = client.EndReceive(ar);

if (bytesRead > 0)
{
state.sb.Append(Encoding.ASCII.GetString(state.buffer, 0, bytesRead));

client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state);
}
else
{
if (state.sb.Length > 1)
{
response = state.sb.ToString();
}
receiveDone.Set();
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}

private void SendCallback(IAsyncResult ar)
{
try
{
Socket client = (Socket)ar.AsyncState;

int bytesSent = client.EndSend(ar);
Console.WriteLine("Sent {0} bytes to server.", bytesSent);

sendDone.Set();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
}
}
}

我希望有人能帮助我,或者向我解释我做错了什么以及我如何才能让它发挥作用。

最佳答案

Team Viewer 执行此操作的方式是在交互中有第三台计算机。 Team Viewer 在 Internet 上有一个公共(public)服务器,您和您所连接的人都可以与之交谈,它所做的只是充当一座桥梁,将传入的消息从一端转发到另一端。现在两端都有出站连接,不需要端口转发。

要对您的系统执行相同的操作,您需要在互联网上设置、托管(付费)和维护一个公共(public)服务器,您的程序的所有用户都可以与之交谈并充当通信的桥梁。

步骤是这样的:

  1. Computer1 打开到 Server1 的出站连接并保持打开状态,他们现在可以在没有端口转发的情况下来回交谈。
  2. 计算机 2 打开到服务器 1 的出站连接并保持打开状态,他们现在可以在没有端口转发的情况下来回交谈。
  3. Computer1 向 Server1 发送一条消息,内容为“将以下内容转发给 Computer2”
  4. 服务器 1 使用计算机 2 启动的步骤 2 中的打开连接来转发消息。
  5. 当 Computer2 想要回复时,它会向 Server1 发送一条消息,内容为“将以下内容转发给 Computer1”
  6. Server1 使用 Computer1 发起的第 1 步中的打开连接来转发消息。
