作为读取消息的服务器，您如何确定消息的长度？

Question

I'm programming a server that accepts an incoming connection from a client and then reads from it (via net.Conn.Read()). I'm going to be reading the message into a []byte slice obviously and then processing it in an unrelated way, but the question is - how do I find out the length of this message first to create a slice of according length?

Answer 1

In the end what I did was create a 1024 byte slice, then read the message from the connection, then shorten the slice to the number of integers read.
