i'm having a trouble with lua.
I need send a request to a website by GET and get the response from website.
Atm all i have is this:
local LuaSocket = require("socket")
client = LuaSocket.connect("example.com", 80)
client:send("GET /login.php?login=admin&pass=admin HTTP/1.0\r\n\r\n")
while true do
s, status, partial = client:receive('*a')
print(s or partial)
if status == "closed" then
break
end
end
client:close()
What should i do to get the response from server ?
I want to send some info to this website and get the result of page.
Any ideas ?

This probably won't work as *a will be reading until the connection is closed, but in this case the client doesn't know how much to read. What you need to do is to read line-by-line and parse the headers to find Content-Length and then after you see two line ends you read the specified number of bytes (as set in Content-Length).
Instead of doing it all yourself (reading and parsing headers, handling redirects, 100 continue, and all that), socket.http will take care of all that complexity for you. Try something like this:
local http = require("socket.http")
local body, code, headers, status = http.request("https://www.google.com")
print(code, status, #body)
