需要通过Socket获得字节帮助(Need help on bytes via Socket)

我正在尝试通过套接字发送一些数据,因此它被转换为字节,然后返回到服务器上的字符串。 但我显然只能做一件事。

服务器代码:

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++;
        }
    }    
}

客户代码:

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();
}

我似乎无法在服务器上正确解密它。 任何人都可以帮助我缓冲区和诸如此类的东西?


I'm trying to send a couple of data via Sockets, so it's converted to bytes and then back to String on the Server. But I can only do one apparently.

Server code:

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++;
        }
    }    
}

Client code:

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();
}

I can't seem to decrypt it properly over on Server. Can anyone help me with the buffersizes and whatnot?

最满意答案

它正在返回HTML,因为它使用quoted-printable编码对其进行编码,这是在邮件消息中实际发送内容的方式。

如果您想获得没有编码的内容,可以试试这个:

$part = $mail->getBodyHtml();   // returns Zend_Mime_Part
if ($part !== false && $part instanceof Zend_Mime_Part) {
    $html = $part->getRawContent(); // returns the raw, unencoded content
}

使用Zend_Mail :: setBodyHtml()设置正文HTML时,可以指定编码。 函数原型是setBodyHtml($html, $charset = null, $encoding = Zend_Mime::ENCODING_QUOTEDPRINTABLE)

有效选项是

  • Zend_Mime :: ENCODING_7BIT
  • Zend_Mime :: ENCODING_8BIT
  • Zend_Mime :: ENCODING_QUOTEDPRINTABLE(默认)
  • Zend_Mime :: ENCODING_BASE64

如果可能,您可以在调用setBodyHtml之前验证HTML,或者使用上面显示的方法检索原始的未编码内容。 否则getBodyHtml()将以其编码格式返回HTML。


It is returning the HTML like that because it is encoding it using quoted-printable encoding which is how the content is actually sent in the mail message.

If you would like to get the content without the encoding, you can try this:

$part = $mail->getBodyHtml();   // returns Zend_Mime_Part
if ($part !== false && $part instanceof Zend_Mime_Part) {
    $html = $part->getRawContent(); // returns the raw, unencoded content
}

When you set the body HTML with Zend_Mail::setBodyHtml(), you can specify the encoding. Function prototype is setBodyHtml($html, $charset = null, $encoding = Zend_Mime::ENCODING_QUOTEDPRINTABLE)

Valid options are

  • Zend_Mime::ENCODING_7BIT
  • Zend_Mime::ENCODING_8BIT
  • Zend_Mime::ENCODING_QUOTEDPRINTABLE (default)
  • Zend_Mime::ENCODING_BASE64

You can either validate the HTML before you call setBodyHtml if possible, or retrieve the raw, unencoded content using the method shown above. Otherwise getBodyHtml() will return the HTML in its encoded format.
