net.sf.jqql.packets._05InPacket
public abstract class _05InPacket
input packet base class 0f 05 series 1. packet header sign, 1 byte 2. source, 2 byte 3. packet length, 2 byte 4. packet command, 2 byte 5. packet sequence number, 2 byte 6. user QQ number, 4 byte 7. packet body 8. packet tail, 1 byte noteworthiness is: packet body of this packet is really not full encryption type, but part encryption. 05系列的输入包基类 1. 包头标识,1字节 2. source,2字节 3. 包长度,2字节 4. 包命令,2字节 5. 包序号,2字节 6. 用户QQ号,4字节 7. 包体 8. 包尾,1字节 值得注意的是:这种包的包体并非完全加密型,而是部分加密型
