Code:
local http= require("socket.http")

print(resp)

I want to get web content, not source code。

Some older codes can give you ideas.
But the need to merge quite challenging. Wink

Example code: http.lua

The "content" of an HTML page is the full HTML. If you want a certain element you'll need to parse the HTML for the element you want. There are a lot of HTML parsers for Lua, just use google to find one and how to use it. Then combine that with what Corroder showed you.

The code you started is pointing in the right direction.
But from the link I've made, get the necessary codes.
Meet the ".lua" requests with the desired names in the error list.
etc .. etc ..

Here:

Code:
local int=getInternet()
local url='https://forum.cheatengine.org/viewtopic.php?t=610183'
local resp=int.getURL(url)
print(resp)
local frm = getLuaEngine()
local log = frm.mOutput.Lines.Text
path = TrainerOrigin or getMainForm()
local f = assert(io.open("content.html", "w"))
f:write(log)
f:close()
local name = path .. "\\content.html"
os.execute(name)


Copy that code above to script table and save as CT file first. Next, re-open the CT file you saved
and execute to match 'path' given.
Or you can change 'path = TrainerOrigin or getMainForm()' to another path like "E:\\content.html", what ever.

This will be doing the same as you open the provided URL with a web browser. That is the 'Content' as you meant. Then if I still not understand with you meant of 'content' then do what @TheyCallMeTim said, parse the URL result.

Here is a sample the HTML parser from the URL you provided.

Code:
nl = "\n"

function HTML_ToText (file)
 local text
 local f=io.open (file)
 if f then
  if f:seek("end") <= 0 then return end
   f:seek("set")
   text = f:read ("*a")
   f:close()
  end
 text = string.gsub (text,"(<([^>]-)>)",function (str) return str:lower() end)

 local devkill=
              {
               ["("..string.char(10)..")"] = " ",
               ["("..string.char(13)..")"] = " ",
               ["("..string.char(15)..")"] = "",
               ["(%s%s+)"]=" ",
               }
 for pat, res in pairs (devkill) do
 text = string.gsub (text, pat, res)
 end

 text = string.gsub (text, "(<%s*head[^>]*>)", "<head>")
 text = string.gsub (text, "(<%s*%/%s*head%s*>)", "</head>")
 text = string.gsub (text, "(<head>,*<%/head>)", "")
 text = string.gsub (text, "(<%s*script[^>]*>)", "<script>")
 text = string.gsub (text, "(<%s*%/%s*script%s*>)", "</script>")
 text = string.gsub (text, "(<script>,*<%/script>)", "")
 text = string.gsub (text, "(<%s*style[^>]*>)", "<style>")
 text = string.gsub (text, "(<%s*%/%s*style%s*>)", "</style>")
 text = string.gsub (text, "(<style>.*<%/style>)", "")
 text = string.gsub (text, "(<%s*td[^>]*>)","\t")
 text = string.gsub (text, "(<%s*th[^>]*>)","\t")
 text = string.gsub (text, "(<%s*br%s*%/%s*>)",nl)
 text = string.gsub (text, "(<%s*li%s*%s*>)"," *  ")
 text = string.gsub (text, "(<%s*/%s*li%s*%s*>)",nl)
 text = string.gsub (text, "(<%s*div[^>]*>)", nl..nl)
 text = string.gsub (text, "(<%s*p[^>]*>)", nl..nl)
 text = string.gsub (text, "(<%s*tr[^>]*>)", nl..nl)
 text = string.gsub (text, "(<%s*%/*%s*ul[^>]*>)", nl..nl)
 local addresses,c = {},0
 text=string.gsub(text,"<%s*a.-href=[\'\"](%S+)[\'\"][^>]*>(.-)<%s*%/*%s*a[^>]->",
 function (url,name)
 c = c + 1
 name = string.gsub (name, "<([^>]-)>","")
 if name:find("%w") then print(url, name, c) table.insert (addresses, {url, name}) return name.."["..#addresses.."]" else return "" end
 end)

 text = string.gsub (text, "(%b<>)","")
 local entities = {}
 setmetatable (entities,
      {
        __newindex = function (tbl, key, value)
          key = string.gsub (key, "(%#)" , "%%#")
          key = string.gsub (key, "(%&)" , "%%&")
          key = string.gsub (key, "(%;)" , "%%;")
          key = string.gsub (key, "(.+)" , "("..key..")")
          rawset (tbl, key, value)
        end
      })
      entities =
      {
        ["&nbsp;"] = " ",
        ["&bull;"] = " *  ",
        ["&lsaquo;"] = "<",
        ["&rsaquo;"] = ">",
        ["&trade;"] = "(tm)",
        ["&frasl;"] = "/",
        ["&lt;"] = "<",
        ["&gt;"] = ">",
        ["&copy;"] = "(c)",
        ["&reg;"] = "(r)",
        ["%&.+%;"] = "",
      }
      for entity, repl in pairs (entities) do
        text = string.gsub (text, entity, repl)
      end

 if #addresses > 0 then
  text=text..nl:rep(2)..("-"):rep(2)..nl
  for key, tbl in ipairs(addresses) do
  text = text..nl.."["..key.."]"..tbl[1]
 end
 end
 return text
end

---------------------------Test Parsing
local int=getInternet()
local url='https://forum.cheatengine.org/viewtopic.php?t=610183'
local resp=int.getURL(url)
print(resp)
local frm = getLuaEngine()
local log = frm.mOutput.Lines.Text
path = TrainerOrigin or getMainForm()
local f = assert(io.open("content.html", "w"))
f:write(log)
f:close()
frm.mOutput.Clear()
local filename = path .. "\\content.html"
local f=io.open(filename..".txt", "w")
f:write(HTML_ToText (filename))
f:close()
os.remove(path.."\\content.html")
--os.rename(path.."\\content.html.txt","content.txt")
--os.execute(path.."\\content.txt")

note = [[
Check the provided path for a file name 'content.html.txt'
and open with notepad to see parsed webpage contents.
]]

The dialogue we can see is exactly what I want.
