我想通過套接字發送一些數據,所以它被轉換爲字節,然後返回到服務器上的字符串。但我只能做一個顯然。需要幫助的字節通過套接字
Server代碼:
static void Read(IAsyncResult ar)
{
int fileNameLen = 1;
//int userNameLen = 9;
State newState = (State)ar.AsyncState; //gets state of Socket
Socket handler = newState.Socket_w; //passes Socket to handler
int bytesRead = handler.EndReceive(ar); //terminates Data Receive from Socket.
if (bytesRead > 0)
{
if (flag == 0)
{
fileNameLen = BitConverter.ToInt32(newState.buffer, 0); //gets filename length
fileName = Encoding.UTF8.GetString(newState.buffer, 4, fileNameLen); //gets filename
//userNameLen = BitConverter.ToInt32(newState.buffer, 8);
//getUsername = Encoding.UTF8.GetString(newState.buffer, 8, fileNameLen);
flag++;
}
}
}
客戶端代碼:
internal static void uploadFile(string host, string username, string getGame, string filename, string filepath)
{
byte[] m_clientData;
Socket clientSock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
byte[] fileName = Encoding.UTF8.GetBytes(username + "_" + filename);
byte[] fileData = File.ReadAllBytes(filepath);
byte[] fileNameLen = BitConverter.GetBytes(fileName.Length);
//byte[] sendUsername = Encoding.UTF8.GetBytes(username);
//byte[] sendUsernameLen = BitConverter.GetBytes(sendUsername.Length);
//byte[] sendGame = Encoding.UTF8.GetBytes(getGame);
//byte[] sendGameLen = BitConverter.GetBytes(sendGame.Length);
m_clientData = new byte[4 + fileName.Length + fileData.Length];
fileNameLen.CopyTo(m_clientData, 0);
fileName.CopyTo(m_clientData, 4);
fileData.CopyTo(m_clientData, 4 + fileName.Length);
//sendUsernameLen.CopyTo(m_clientData, 0);
//sendUsername.CopyTo(m_clientData, 4);
//sendGameLen.CopyTo(m_clientData, 0);
//sendGame.CopyTo(m_clientData, 4);
clientSock.Connect(host, 8889);
clientSock.Send(m_clientData); //tofix exception
clientSock.Close();
}
我似乎無法正確地在解密服務器上。任何人都可以幫我緩衝區和什麼?
你是什麼意思,你不能解密它?你的意思是你沒有看到字節,或者未加密的結果不是原始文件,或者試圖解密它,你會得到一個錯誤信息? –
我的意思是說,我得到的結果與\ 0 \ 0 \ 0混雜在一起,或者由於錯誤的緩衝區解析而導致文本亂碼。 – user1943911
