using lua is it possible to download from url??

Below code i have tried but not getting

1) using curl

local curl = require "luacurl"
local c = curl.new()

function GET(url)
    c:setopt(curl.OPT_URL, url)
    local t = {} -- this will collect resulting chunks
    c:setopt(curl.OPT_WRITEFUNCTION, function (param, buf)
        table.insert(t, buf) -- store a chunk of data received
        return #buf
    end)
    c:setopt(curl.OPT_PROGRESSFUNCTION, function(param, dltotal, dlnow)
        print('%', url, dltotal, dlnow) -- do your fancy reporting here
    end)
    c:setopt(curl.OPT_NOPROGRESS, false) -- use this to activate progress
    assert(c:perform())
    return table.concat(t) -- return the whole data as a string
end

local s = GET 'http://pbs.twimg.com/media/CCROQ8vUEAEgFke.jpg'

print(s)

2)

    local http = require("socket.http")
    local body, code = http.request("http://pbs.twimg.com/media/CCROQ8vUEAEgFke.jpg")
    if not body then error(code) end

    -- save the content to a file
    local f = assert(io.open('/home/jiby/test.jpg', 'wb')) -- open in "binary" mode
    f:write(body)

f:close()

Any other solutions??
