JavaサーバーからC＃クライアントにファイルを送信する方法と、C＃からJavaに完全な確認メッセージを受信する方法に関する小さなチュートリアルを教えてください。実際、私はC#が初めてで、ソケットプログラミングの方法がわかりません。私は長い間それで立ち往生しています。多くのコードを試しました。一部のコードは、不完全なファイルを受け取り、一部は無限ループに陥っています。この点で私を助けてください。ありがとう
編集 これが私が試したことです：
C# サーバー:
{
IPAddress ipAd = IPAddress.Parse("192.168.1.131");
// use local m/c IP address, and
// use the same in the client
/* Initializes the Listener */
TcpListener myList = new TcpListener(ipAd, 5600);
/* Start Listeneting at the specified port */
myList.Start();
Console.WriteLine("The server is running at port 5600...");
Console.WriteLine("The local End point is :" +
myList.LocalEndpoint);
Console.WriteLine("Waiting for a connection.....");
m:
clientSock = myList.AcceptSocket();
//clientSock.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReceiveTimeout,10000);
Console.WriteLine("Connection accepted from " + clientSock.RemoteEndPoint);
//byte[] b = new byte[100];
//int k = clientSock.Receive(b);
string fileName = "hello.wav";
NetworkStream networkStream = new NetworkStream(clientSock);
StreamReader sr = new StreamReader(networkStream);
//read file length
int length = int.Parse(sr.ReadLine());
if (networkStream.CanRead)
{
BinaryWriter bWrite = new BinaryWriter(File.Open(receivedPath + fileName, FileMode.Create));
int receivedBytesLen = -1;
byte[] clientData = new byte[4096 * 5000];
receivedBytesLen = networkStream.Read(clientData, 0, clientData.Length);
bWrite.Write(clientData, 0, receivedBytesLen);
do
{
receivedBytesLen = networkStream.Read(clientData, 0,clientData .Length);
bWrite.Write(clientData, 0, receivedBytesLen);
} while (receivedBytesLen > 0);
bWrite.Close();
networkStream.Close();
}
Console.WriteLine("Client:{0} connected & File {1} started received.", clientSock.RemoteEndPoint, fileName);
Console.WriteLine("File: {0} received & saved at path: {1}", fileName, receivedPath);
Recognizer_2 recognizeVoice = new Recognizer_2(clientSock);
recognizeVoice.recognize_wav(); // Acknowledgement
Console.WriteLine("\nResult Sent to the Client");
goto m;
}
Java クライアント:
Socket socket = new Socket("192.168.1.131", 5600);
BufferedReader response_Stream = new BufferedReader(
new InputStreamReader(socket.getInputStream()));
File f = new File(mFileName);
byte[] buffer = new byte[(int) f.length()];
FileInputStream fis = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(fis);
bis.read(buffer, 0, buffer.length);
OutputStream outputStream = socket.getOutputStream();
outputStream.write(buffer);
outputStream.flush();
String final_Result_String = "";
if (response_Stream != null) {
String respose_text = "";
while ((respose_text = response_Stream.readLine()) != null) {
final_Result_String += respose_text;
}
}
Toast.makeText(getApplicationContext(), final_Result_String, 1)
.show();
outputStream.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
