看到代码里有段逻辑是进行协议序号校验的,可以防止重放攻击:
// 数据包序列号验证
if seq_id != sess.PacketCount {
sess.Flag |= SESS_KICKED_OUT
return nil
}
很多情况下这可能造成误判,有时候并不是故意重放,比如客户端由于网络原因没有收到服务器回包,会重发上一次请求,这属于正常重放。

似乎是这里的case <-sess.Die无法进去,不知道该怎么改...
for {
// solve dead link problem:
// physical disconnection without any communcation between client and server
// will cause the read to block FOREVER, so a timeout is a rescue.
conn.SetReadDeadline(time.Now().Add(config.readDeadline))
// read 2B header
n, err := io.ReadFull(conn, header)
if err != nil {
log.Warningf("read header failed, ip:%v reason:%v size:%v", sess.IP, err, n)
return
}
size := binary.BigEndian.Uint16(header)
// alloc a byte slice of the size defined in the header for reading data
payload := make([]byte, size)
n, err = io.ReadFull(conn, payload)
if err != nil {
log.Warningf("read payload failed, ip:%v reason:%v size:%v", sess.IP, err, n)
return
}
// deliver the data to the input queue of agent()
select {
case in <- payload: // payload queued
case <-sess.Die:
log.Warningf("connection closed by logic, flag:%v ip:%v", sess.Flag, sess.IP)
return
}
}
既然现在不依赖gvp/gvm了,是不是可以改下目录结构来支持go get
只要设定好了GOPATH, 直接
go get -u github.com/gonet2/{agent,game}
就可以clone并安装好agent和game
方便快速的体验
同一个grpc连接,当stream创建超过100个的话,超出的stream创建会卡死
也就是说agent和game之间最多只能创建100个session的链接
