问题
在LuaSocket 引言之后,我设法使服务器运行。我还设法从客户端连接。但是,我注意到服务器脚本会冻结,直到server:accept()获得连接。
Research
LuaSocket 参考文献指定:
使用settimeout方法或接受可能会阻塞,直到另一个客户端出现。
这甚至包括在示例代码中。但是,client:settimeout(10)是在local client = server:accept()之后调用的,因此脚本在到达此点之前就会被阻塞。
我读到可以通过多线程来解决这个问题,但这似乎有点夸张。
问题
client:receive() (服务器端)和tcp:receive() (客户端)(或client:settimeout(10)负责处理)出现类似的问题?码
服务器(来自LuaSocket 引言)
-- load namespace
local socket = require("socket")
-- create a TCP socket and bind it to the local host, at any port
local server = assert(socket.bind("*", 0))
-- find out which port the OS chose for us
local ip, port = server:getsockname()
-- print a message informing what's up
print("Please telnet to localhost on port " .. port)
print("After connecting, you have 10s to enter a line to be echoed")
-- loop forever waiting for clients
while 1 do
-- wait for a connection from any client
local client = server:accept()
-- make sure we don't block waiting for this client's line
client:settimeout(10)
-- receive the line
local line, err = client:receive()
-- if there was no error, send it back to the client
if not err then client:send(line .. "\n") end
-- done with client, close the object
client:close()
end客户端(跟随这个答案)
local host, port = "127.0.0.1", 100
local socket = require("socket")
local tcp = assert(socket.tcp())
tcp:connect(host, port);
--note the newline below
tcp:send("hello world\n");
while true do
local s, status, partial = tcp:receive()
print(s or partial)
if status == "closed" then break end
end

您应该能够在调用服务器:timeout()之前使用server:accept()。
server:settimeout(2)
local client, err = server:accept()
print(client, err)如果在2秒内没有收到任何请求,这将为我打印nil timeout。
