这是一个 luasocket 范例。
7+
8+
为了便于使用，我封装了 luasocket 到 cc.net.SocketTCP 类中。这个范例展示如何使用 cc.net.SocketTCP。
9+
10+
同时，在本范例中还使用了 cc.utils.ByteArray 和 cc.utils.ByteArrayVarint。
11+
12+
要了解更多关于 cc.net.SocketTCP 和 cc.utils.ByteArray 的信息，请阅读 [一个LuaSocket封装][6] 和 [用lua实现ByteArray和ByteArrayVarint][7] .
13+
14+
在本范例的 net 包中，有3个 lua 类：
15+
16+
* [net.PacketBuffer][2]
17+
我们收到的数据包经常是不完整的，特别是当数据包比较大的时候。因此我们必须确保数据包完整才能使用。PacketBuffer 就是做这件事的。
18+
* [net.Protocol][3]
19+
这个类把数据包解析成人类可读的格式。它转换一个数据包到一个lua table，并且为每个数据项命名。数据项的名称定义在 [net.protocols][4] 文件中。
20+
* [net.protocols][4]
21+
这是你的协议定义文件。你可以写一个生成器程序来生成它。
22+
23+
下面是本范例运行的log文件。当然，你需要自己实现服务端程序。

This is a luasocket sample. I encapsulate luasocket into cc.net.SocketTCP class.
7+
8+
This sample will show you how to use the cc.net.SocketTCP.
9+
10+
This sample also needs cc.utils.ByteArray and cc.utils.ByteArrayVarint.
11+
12+
For more information about cc.net.SocketTCP and cc.utils.ByteArray, see [lua SocketTCP][6] and [ByteArray in lua][7] .
13+
14+
There are 3 lua files in the net package:
15+
16+
* [net.PacketBuffer][2]
17+
The data package may be incomplete, especially it is larger. So we must ensure to get a intact data to use it. PacketBuffer can do it.
18+
* [net.Protocol][3]
19+
Protocol splits a complete data package to human-readable format. It convert a data stream to a lua table and names all data item. The names defined in [net.protocols][4] .
20+
* [net.protocols][4]
21+
Your all protocols. It is generated by a generator.
22+
23+
There is a log file that run this sample. Of cause, you can implement a server application by youself.
