Re: [OT?] What does Firefox do that lua-curl can't?

You need a cookie management module like this:

https://github.com/aryajur/luacookie

It can be used something like this:

        lc = require("luacookie")

local cm = lc.new()

-- Login 

local hdrs,msg,resp, URI

URI = [[http://www.design-reuse.com/login2.php]]

print("Try connection to "..URI)

-- Got the form fill details from the chrome developer console

local b,c,l,h = http.request(URI ,formencode({

go = "ok",

nexturl = [[http://www.website.com/]] ,

username = [[username]] ,

password = [[La8TZmMc]] ,

autolog = "X"

}))

if not b then

print("Error making connection: "..tostring(c))

return

end

hdrs,msg = cm.add(l,URI)

local ft = {}

print("Try the check login url with the cookie.")

URI = l.location

hdrs, msg = cm.getCookieHeader(URI)

if not hdrs then return nil,msg end

resp = {http.request{

url = "">

sink = ltn12.sink.table(ft),

headers = hdrs

}

}

print("Done with the http request.")

if not resp[1] then 

return nil,resp[2]

end

So basically you create a new cookie manager (cm) and then after each request just pass the header table to the add function in the cookie manager and then in the next request get the header using getCookieHeader function of the cookie manager. This has worked for me in the past few occasions requiring cookie management for websites that require login.

There is a package on Luarocks called lua-curl. With it, I can surf
the Internet form inside my Lua program.

Or so I thought. After all, all that Firefox and friends do is to send
a URL with everything you are communicating to a server and displaying
or otherwise utilizing the stuff it sends back.

I found that I could do general surfing thta way but did not succeed
in logging in to a site on which I am a registered user.

Maybe this is off-topic for this list. But maybe someone has used
lua-curl and knows what to do.
