skynet http请求客户端

同时开多个导致协程挂了，这种应该用go。

local skynet = require "skynet" local socket = require "skynet.socket" skynet.start(function () local ser = {} num = 30 for i=1, num do -- url = string.format("https://meituba.jmsla.cn/uploads/allimg/2019/04/02/92_26%02d.jpg", i) --skynet.error(url); --skynet.newservice("testhttp2", url) --直接传url ser[i] = skynet.newservice("testhttp2") end for i=1, num do url = string.format("https://meituba.jmsla.cn/uploads/allimg/2019/04/02/92_23%02d.jpg", i) skynet.send(ser[i], "lua", "http_task", url) end --[[ for _, v in pairs (url) do skynet.newservice("testhttp2", v) --直接传url --local task = skynet.newservice("testhttp2") --skynet.send(task, "lua", "http_task", v) end ]] --skynet.exit() -- local hall = skynet.uniqueservice("hall") --hall是唯一服 --socket.start(listenfd, accept) -- 绑定listenfd, actor 与 epoll end) local skynet = require "skynet" local httpc = require "http.httpc" local utime = require "usertime" local arg = ... local CMD = {} function CMD.http_task(url) local millisecond = utime.getmillisecond() local host local resource local filename local pos = string.find(url, "/", 9) host = string.sub(url, 1, pos-1) --print(host) resource = string.sub(url, pos) --print(resource) filename = string.format("./img/%s", string.gsub(resource, "/", "_")) --print(filename) httpc.timeout = 300 -- set timeout 3 second local respheader = {} skynet.error("get ".. url) local status, body = httpc.get(host, resource, respheader) --for k,v in pairs(respheader) do -- print(k..":"..v) --end --string.format("%s %s", url, status) skynet.error(string.format("-- %s %s", url, status)) if status == 200 then local f = io.open(filename, "w") f:write(body) f:close() else skynet.error("error: ".. url) end local millisecond2 = utime.getmillisecond() skynet.error('use time ', (millisecond2-millisecond)/1000.0, " sec") skynet.exit() end skynet.start(function() --local f = CMD["http_task"] --f(arg) skynet.dispatch("lua", function (_, _, cmd, ...) local f = CMD[cmd] if f then f(...) end --assert(f) end) end)

结果：，有时直接init service失败了
