????sproto的简介略过,这里直接上代码,新建proto.lua文件,内容如下:
local sprotoparser =
require
"sprotoparser"
local proto =
{}
proto.c2s = sprotoparser.parse [[
.package {
????type 0 : integer
????session 1 : integer
}
handshake 1 {
????response {
????????msg 0 : string
????}
}
say 2 {
????request {
????????name 0 : string
????????msg 1 : string
????}
}
quit 3 {}
]]
proto.s2c = sprotoparser.parse [[
.package {
????type 0 : integer
????session 1 : integer
}
heartbeat 1 {}
]]
return proto
新建client1.lua文件,内容如下:
package.cpath
=
"luaclib/?.so"
package.path
=
"lualib/?.lua;myexample/?.lua"
if
_VERSION
~=
"Lua 5.3"
then
????error
"Use lua 5.3"
end
local socket =
require
"client.socket"
-- 通信协议
local proto =
require
"proto"
local sproto =
require
"sproto"
local host = sproto.new(proto.s2c):host "package"
local request = host:attach(sproto.new(proto.c2s))
local fd =
assert(socket.connect("127.0.0.1",
8888))
local session =
0
local
function send_request(name, args)
????session = session +
1
????local str = request(name, args, session)
????-- 解包测试
????-- local host2 = sproto.new(proto.c2s):host "package"
????-- local type,str2 = host2:dispatch(str)
????-- print(type)
????-- print(str2)
????socket.send(fd, str)
????print("Request:", session)
end
send_request("handshake")
send_request("say",
{ name =
"soul", msg =
"hello world"
})
while
true
do
????-- 接收服务器返回消息
????local str = socket.recv(fd)
????-- print(str)
????if str~=nil
and str~=""
then
????????????print("server says: "..str)
????????????-- socket.close(fd)
????????????-- break;
????end
????-- 读取用户输入消息
????local readstr = socket.readstdin()
????if readstr then
????????if readstr ==
"quit"
then
????????????send_request("quit")
????????????-- socket.close(fd)
????????????-- break;
????????else
????????????-- 把用户输入消息发送给服务器
????????????send_request("say",
{ name =
"soul", msg = readstr })
????????end
????else
????????socket.usleep(100)
????end
end
新建socket1.lua,内容如下:
local skynet =
require
"skynet"
require
"skynet.manager"????-- import skynet.register
local socket =
require
"skynet.socket"
local proto =
require
"proto"
local sproto =
require
"sproto"
local host
local REQUEST =
{}
function REQUEST:say()
????print("say", self.name, self.msg)
end
function REQUEST:handshake()
????print("handshake")
end
function REQUEST:quit()
????print("quit")
end
local
function request(name, args, response)
????local f =
assert(REQUEST[name])
????local r = f(args)
????if response then
????????-- 生成回应包(response是一个用于生成回应包的函数。)
????????-- 处理session对应问题
????????-- return response(r)
????end
end
local
function send_package(fd,pack)
????-- 协议与客户端对应(两字节长度包头+内容)
????local
package
= string.pack(">s2", pack)
????socket.write(fd,
package)
end
local
function accept(id)
????-- 每当 accept 函数获得一个新的 socket id 后,并不会立即收到这个 socket 上的数据。这是因为,我们有时会希望把这个 socket 的操作权转让给别的服务去处理。
????-- 任何一个服务只有在调用 socket.start(id) 之后,才可以收到这个 socket 上的数据。
????socket.start(id)
????host = sproto.new(proto.c2s):host "package"
????-- request = host:attach(sproto.new(proto.c2s))
????while
true
do
????????local str = socket.read(id)
????????if str then
????????????local
type,str2,str3,str4 = host:dispatch(str)
????????????if
type=="REQUEST"
then
????????????????-- REQUEST : 第一个返回值为 "REQUEST" 时,表示这是一个远程请求。如果请求包中没有 session 字段,表示该请求不需要回应。这时,第 2 和第 3 个返回值分别为消息类型名(即在 sproto 定义中提到的某个以 . 开头的类型名),以及消息内容(通常是一个 table );如果请求包中有 session 字段,那么还会有第 4 个返回值:一个用于生成回应包的函数。
????????????????local ok, result =
pcall(request, str2,str3,str4)
????????????????if ok then
????????????????????if result then
????????????????????????socket.write(id,
"收到了")
????????????????????????-- 暂时不使用回应包回应
????????????????????????-- print("response:"..result)
????????????????????????-- send_package(id,result)
????????????????????end
????????????????else
????????????????????skynet.error(result)
????????????????end
????????????end
????????????if
type=="RESPONSE"
then
????????????????-- RESPONSE :第一个返回值为 "RESPONSE" 时,第 2 和
第 3 个返回值分别为 session 和消息内容。消息内容通常是一个 table ,但也可能不存在内容(仅仅是一个回应确认)。
????????????????-- 暂时不处理客户端的回应
????????????????print("client response")
????????????end????????
????????else
????????????socket.close(id)
????????????return
????????end
????end
end
skynet.start(function()
????print("==========Socket Start=========")
????local id = socket.listen("127.0.0.1",
8888)
????print("Listen socket :",
"127.0.0.1",
8888)
????socket.start(id ,
function(id, addr)
????????????-- 接收到客户端连接或发送消息()
????????????print("connect from "
.. addr ..
" "
.. id)
????????????-- 处理接收到的消息
????????????accept(id)
????????end)
????--可以为自己注册一个别名。(别名必须在 32 个字符以内)
????skynet.register "SOCKET1"
end)
