Lua编译

LuaSocket编译

  • sudo git clone https://github.com/diegonehab/luasocket
  • cd luasocket
  • sudo make clean all install LUAV=5.3

使用范例

包引用

  • local socket = require("socket")

连接

服务端

host = "*"
port = 8080
--创建TCPsoket
server = socket.bind(host, port)
--获取连接信息
i, p = server:getsockname()
--设置超时时间
socket:settimeout(5)
--等待连接
client = server:accept()

host = "localhost"
port = 8080
--连接
client = socket.connect(host, port)
--设置超时时间
client:settimeout(5)

接受/发送

接收端

1
l, e = client:receive()

发送端

1
2
3
str = "hello"
-- 发送端结尾一定要加`\n`
c:send(str .. "\n")

其他接口

  • setoption(option [, value])：进行keepalive等设置
  • client:shutdown(mode)：mode = [both/send/receive]，关闭全双工连接的全部或部分

luaSocket其他功能

  • DNS
  • FTP
  • HTTP
  • LTN12
  • MIME
  • SMTP
  • UDP
  • URL
