修改LumaQQ.NET,使其支持长消息发送

        默认LumaQQ.NET不支持发送长消息,只能文字量比较小的文字信息。其实在内部设计上,已经支持了分片发送的功能,只是没有去拆分实现。我们这就来自己实现它。

1.首先在QQGlobal里添加消息最长长度定义:

   1: /// <summary>
   2: /// 消息最大长度,QQ是最大699字节   LumaQQ里说最长是700,但是我试下来只能是699,700就会出错,不知道为什么
   3: /// </summary>
   4: public const int QQ_MAX_SEND_IM = 699;

 

2.修改MessageManager里其中2个SendIM的方法

   1: /// <summary>
   2: /// 发送普通信息
   3: ///  <remark>abu 2008-03-11 </remark>
   4: /// </summary>
   5: /// <param name="receiver">The receiver.</param>
   6: /// <param name="message">The message.</param>
   7: /// <param name="fontSytle">The font sytle.</param>
   8: public void SendIM(int receiver, string message, FontStyle fontSytle)
   9: {
  10:     int MaxByte = QQGlobal.QQ_MAX_SEND_IM;//取最长长度
  11:  
  12:  
  13:     if (Encoding.GetEncoding(QQGlobal.QQ_CHARSET_DEFAULT).GetBytes(message).Length > MaxByte)//判断是不是要分段发送
  14:     {
  15:         List<byte> messageBytes = new List<byte>();
  16:         messageBytes.AddRange(Utils.Util.GetBytes(message));
  17:         messageBytes.Add(0x20);//补一个空格,不补似乎也会出问题
  18:         int messageSize = messageBytes.Count;
  19:  
  20:         int totalFragments = ((messageSize % MaxByte) > 0) ? (messageSize / MaxByte + 1) : (messageSize / MaxByte);//计算分片数
  21:         for (int fragementSequence = 0; fragementSequence < totalFragments; fragementSequence++)
  22:         {
  23:             int index = fragementSequence * MaxByte;
  24:             int BytesSize = ((messageSize - index) > MaxByte) ? MaxByte : (messageSize - index);//不能每次都申请最大长度的byte数组,不然字体会出问题
  25:             byte[] messageFragementBytes = new byte[BytesSize];
  26:  
  27:  
  28:             messageBytes.CopyTo(index, messageFragementBytes, 0, BytesSize);
  29:             SendIM(receiver, messageFragementBytes, totalFragments, fragementSequence, fontSytle);
  30:  
  31:  
  32:         }
  33:     }
  34:     else
  35:     {
  36:         SendIM(receiver, Utils.Util.GetBytes(message), 1, 0, fontSytle);
  37:     }
  38: }
  39: /// <summary>
  40: /// 发送普通信息
  41: ///  <remark>abu 2008-03-11 </remark>
  42: /// </summary>
  43: /// <param name="receiver">The receiver.</param>
  44: /// <param name="message">The message.</param>
  45: /// <param name="totalFragments">The total fragments.总分块数</param>
  46: /// <param name="fragementSequence">The fragement sequence.当前当块序号</param>
  47: /// <param name="fontSytle">The font sytle.</param>
  48: public void SendIM(int receiver, byte[] message, int totalFragments,
  49:     int fragementSequence, FontStyle fontSytle)
  50: {
  51:     SendIMPacket packet = new SendIMPacket(QQUser);
  52:     packet.Receiver = receiver;
  53:     packet.Message = message;//Utils.Util.GetBytes(message);
  54:     packet.TotalFragments = totalFragments;
  55:     packet.FragmentSequence = fragementSequence;
  56:     packet.FontStyle = fontSytle;
  57:     QQClient.PacketManager.SendPacket(packet, QQPort.Main.Name);
  58: }
