- 库名为socket(而非luasocket)。
- 当前版本( require("socket")._VERSION )为3.0-rc1。
- master+bind-listen local address=service
master+connect remote address=client
- service.accept/getsockname/setoption/settimeout/close
client.send/receive/getsockname/getpeername/setoption/settimeout/shutdown/close
- in server, client=server:accept()
then client:send/receive
- in client, only has concept of tcp(master) (no server/client), and host+port (of server).
then tcp:send/receive
- 安装telnet。win+q搜telnet,“windows功能”对话框列表中找到并勾选即可安装。
- 使用telnet。
- o localhost <port> (不可使用0.0.0.0)建立连接;
- 建立连接后, sen ... ,但总是“遗失对主机的连接。”输入的内容直接被发送到服务端(无需 sen 命令)。
- 建议更改Luasocket测试例 if not err then client:send(line .. "
") end 为
if not err then client:send("received: '" line .. "'. ") end
否则telnet中收到的消息如
sen abc
遗失对主机的连接。按任意键继续...
以为失败了呢...其实是server中 client:send(...) 后 client:close() 。
- server/client都可以close,对方(client/server)会收到(receive)状态(status/error message) s, status/err, partial = tcp:receive() 值为"close"。参见reference eceive。
- autohotkey(AHK) tcp:见下链接。
- CONNECTED/ACCEPTED event is fired on both client and server
- the server/client can both receives the DISCONNECT event
- 建立TCP连接需要时间。

tcp:listen() 。
测试例用法:
- telnet连接后,发送 GET / 回车, a:b ..回车;发送 GET /mouse 回车;..
- 游览器打开地址http://localhost:1337/(可以多开)。游览器会向服务端请求信息,服务端返回。
- 可以修改 setTimeout ,配合 OutputDebug, % Line 查看游览器向服务端请求信息。
修改版,增加timeout,参见iPhilip的回帖。
