我正在一个统一的项目中,用户可以使用TCP / IP将数据从客户端发送到服务器。我能够发送数据。但是我的团结停滞不前,直到从网络流中读取数据。
服务器代码:读取数据。
public void StartServer (){
// Start TcpServer background thread
tcpListenerThread = new Thread (new ThreadStart(ListenForIncommingRequests));
tcpListenerThread.IsBackground = true;
tcpListenerThread.Start();
startServerButton.interactable = false;
path = UnityEditor.EditorUtility.SaveFolderPanel ("Any type of File.", "", ""); // Path.Combine(path,"D:\\Siva\\TCPDownloadfiles");
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown(KeyCode.Space)) {
SendMessage();
}
}
/// <summary>
/// Runs in background TcpServerThread; Handles incomming TcpClient requests
/// </summary>
private void ListenForIncommingRequests () {
Thread threadForDownloading = new Thread (new ThreadStart(DownloadingStreamData));
threadForDownloading.IsBackground = true;
threadForDownloading.Start();
//DownloadingStreamData ();
}
private void DownloadingStreamData()
{
try {
fileCount++;
int fileNameLen;
byte[] incommingData = new byte[1024];
string ext = "";
// Create listener on localhost port 8052.
tcpListener = new TcpListener(IPAddress.Parse("127.0.0.1"), 8052);
tcpListener.Start();
Debug.Log("Server is listening");
bytes = new Byte[Int32.MaxValue]; // 2221024
while (true) {
using (connectedTcpClient = tcpListener.AcceptTcpClient()) {
// Get a stream object for reading
using (stream = connectedTcpClient.GetStream()) {
Debug.Log("Befor Stream Read..........");
IAsyncResult result = stream.BeginRead(bytes, 0, bytes.Length, MessageReceived, stream);
result.AsyncWaitHandle.WaitOne();
// Read incomming stream into byte arrary.
do{
//length = stream.Read(bytes, 0, bytes.Length);
//length = s_bytesReceived;
Debug.Log("After Stream Read.........."+length);
incommingData = new byte[length];
Array.Copy(bytes, 0, incommingData, 0, length - 4);
// Convert byte array to string message.
fileNameLen = BitConverter.ToInt32(incommingData, 0);
string clientMessage = Encoding.ASCII.GetString(incommingData,4, fileNameLen);
ext = Path.GetExtension(clientMessage);
//Debug.Log("client message received as: " + clientMessage);
//File.WriteAllBytes(path + "\\temp"+fileCount.ToString()+ext, incommingData);
BinaryWriter bWrite = new BinaryWriter(File.Open(path + "\\temp"+fileCount.ToString()+ext, FileMode.Create)); ;
bWrite.Write(incommingData, 4 + fileNameLen, length - 4 - fileNameLen);
bWrite.Flush();
bWrite.Close();
} while(stream.DataAvailable);
//Debug.Log("Bytes length2 :>>>"+" "+fileNameLen +" Incoming data length" +incommingData.Length);
//connectedTcpClient.Close();
//stream.Flush();
//stream.Close();
//Debug.Log("GETTING FILE NAME THROUGH BUFFER ::"+stream);
}
}
}
}
catch (SocketException socketException) {
Debug.Log("SocketException " + socketException.ToString());
}
}
我尝试使用stream.BeginRead方法,但是这引发了异常,例如Stream / socket已被处置,并尝试在客户端代码上访问它。
但是stream.Read方法像我期望的那样工作,但是它停顿/冻结了单位直到获得数据。请给我一些更好的解决方案。预先感谢。
客户代码:发送数据
if (stream.CanWrite) {
string path = UnityEditor.EditorUtility.OpenFilePanel ("Any type of File.", "", "");
WWW www = new WWW ("file:///" + path);
byte[] fileNameBytes = Encoding.ASCII.GetBytes(path);
byte[] fileDataBytes = www.bytes;
byte[] fileNameLength = BitConverter.GetBytes(fileNameBytes.Length);
clientData = new byte[4 + fileNameBytes.Length + fileDataBytes.Length];
fileNameLength.CopyTo(clientData, 0);
fileNameBytes.CopyTo(clientData, 4);
fileDataBytes.CopyTo(clientData, 4 + fileNameBytes.Length);
Debug.Log ("FIle sends to server path : "+path);
//stream.BeginRead(clientData, 0, clientData.Length, MessageReceived, stream);
try {
stream.Write(clientData, 0, clientData.Length);
//stream.BeginWrite(clientData, 0, clientData.Length, MessageReceived, stream);
}catch (Exception e) {
Debug.Log("SocketException " + e.ToString());
}
