Luasocket TCP在\ r \ n \ r \ n之后停止侦听 [英] Luasocket TCP stops listening after \r\n\r\n

问题描述

每当我使用以下方式接收TCP消息时:

Whenever I receive TCP messages using something like this:

local socket=require "socket"
local sv=socket.bind("*",1337)
function love.update(dt)
    local s=sv:accept()
    while true do
        local s,e=s:receive()
        print(e or s)
    end
end

它可以很好地与\r\n间隔的http标头一起工作，但是当我尝试对其进行http POST时，我得到的标头很好，但是数据却没有，巫婆在后面并且是空行(\ r \ n \ r \ n ) 当我将其用作客户端时，它会做同样的事情:

It works perfectly fine with \r\n spaced http headers, but when I try to http POST to it, I get the headers fine but not the data, witch is after and empty line (\r\n\r\n) it does the same thing when i use this as a client:

s.socket_write(h,"test1\r\ntest2\r\n\r\ntest3") -- (not luasocket)

我看到了test1和test2

I see test1 and test2

我尝试弄乱setOption函数，但是没有用

I've tried messing around with the setOption function but it didnt work

有什么方法可以接收数据吗?

Is there any way to receive the data?

推荐答案

我不确定您期望什么，但是默认的模式"是读取一行，因为您的字符串"test1\r\ntest2\r\n\r\ntest3"没有换行符最后，receive调用等待该换行符.

I'm not sure what you expect, but the default "mode" is to read one line and because your string "test1\r\ntest2\r\n\r\ntest3" doesn't have a newline in the end, the receive call waits for that newline.

通常，在阅读标题之后，您已经知道要阅读的内容的长度，因此可以执行s:receive(number_of_bytes_to_read)(至少这是我的工作，并且没有任何问题).

Usually, after you read the headers, you already know the length of the content you want to read, so you can then do s:receive(number_of_bytes_to_read) (at least this is what I do and it works without any issues).
