01、API

• newservice(name, ...)： 阻塞的形势启动一个名为 name 的新服务，待start函数执行完后会返回这个服务的地址。
• uniqueservice(name, ...)：针对于当前节点，启动一个唯一服务（相当于单例），如果服务该服务已经启动，则返回已启动的服务地址。
• queryservice(true, name, ...)：针对于所有节点，启动一个唯一服务。
• queryservice(name) ：查询一个由uniqueservice 启动的唯一服务的地址，若该服务尚未启动则等待。
• queryservice(true,name)： 查询一个由uniqueservice 启动的唯一服务的地址，若该服务尚未启动则等待。

02、Demo1 服务与唯一服务

配置

project = "../project/02service/"

thread = 8
cpath = "./cservice/?.so"
bootstrap = "snlua bootstrap"
start = "serviceTest"
harbor = 1 
address = "127.0.0.1:2526"
master = "127.0.0.1:2013"
standalone = "0.0.0.0:2013" -- 主节点
lualoader = "./lualib/loader.lua"
luaservice = "./service/?.lua;"..project.."?.lua;"..project.."worker/?.lua;"
lua_path =  "./lualib/?.lua;" .. "./lualib/?/init.lua;"
lua_cpath = "./luaclib/?.so"

代码

work1.lua

local skynet = require "skynet"

local param1 = ""
local param2 = ""

skynet.init(function ()
    skynet.error("[work1] init work param1",param1,"param2",param2)
end)

local function initParams(p1, p2)
    skynet.error("[work1] initParams p1",p1,"p2",p2)
    param1 = p1
    param2 = p2
end

-- 调用初始化函数，...是不定参数，会从skynet.newservice的第二个参数开始透传过来
initParams(...)

local function doWork()
    while true do
        skynet.error("---------work----------------")
        skynet.sleep(200)
    end
end

skynet.start(function ()
   skynet.error("worker start param1 = ",param1,"param2 = ",param2)
   -- doWork()
end)

serviceTest.lua

local skynet = require "skynet"

local function test1()
	local h1 =  skynet.newservice("work1","work001","10086")
	local h2 =  skynet.newservice("work1","work002","1008611")
	local h3 =  skynet.uniqueservice("work1","work003","1008612")
	local h33 =  skynet.uniqueservice("work1","work004","1008613") -- 这里并没有调用initParams与init函数
	skynet.error("h1",h1,"h2",h2,"h3",h3,"h33",h33)
end

skynet.start(function()
	skynet.error("[service main] start")
	skynet.error("-----------test service begin--------------")
	test1();
	skynet.error("-----------test service end--------------")	
	skynet.error("[service main] end")
	skynet.exit()
end)

03、Demo1唯一服务与全局唯一服务

配置

project = "../project/02service/"

thread = 8
cpath = "./cservice/?.so"
bootstrap = "snlua bootstrap"
start = "serviceTest"
harbor = 2 -- 修改节点
address = "127.0.0.1:2527" -- 修改从节点端口
master = "127.0.0.1:2013"
lualoader = "./lualib/loader.lua"
luaservice = "./service/?.lua;"..project.."?.lua;"..project.."worker/?.lua;"
lua_path =  "./lualib/?.lua;" .. "./lualib/?/init.lua;"
lua_cpath = "./luaclib/?.so"

代码

local function test2()
	local h1 =  skynet.uniqueservice("work1","work001","10086")
	local h2 =  skynet.uniqueservice("work1","work002","1008611")
	local h3 =  skynet.uniqueservice("work1","work003","1008612")
	skynet.error("h1",h1,"h2",h2,"h3",h3)
	local h33 = skynet.queryservice("work1")
	skynet.queryservice("work1")
end

skynet.start(function()
	skynet.error("[service main] start")
	skynet.error("-----------test service begin--------------")
	test2();
	skynet.error("-----------test service end--------------")	
	skynet.error("[service main] end")
	skynet.exit()
end)
