http.request more then 1 command in the same session

How to execute more then one http request in the same web sessions?

Code:

12345678910111213

function openDoor(iLoxxId)   require('socket.http')  socket.http.TIMEOUT = 5     local urlLogin = 'http://'..wl_IP..'/login.cgi?Source=Webpage&Username='..wl_USR..'&Password='..wl_PWD  local urlAccess = 'http://'..wl_IP..'/setRemoteAccess.cgi?Source=Webpage&LoxxId='..iLoxxId..'&Action=Start'   wl_login_data = socket.http.request(urlLogin)   log(wl_login_data)   wl_access = socket.http.request(urlAccess)   log(wl_access)  end openDoor(19)

I have a request for  login and another request for opening the door. But now i received: 401 Authorization Required

If i execute both statements in the browser it works.

Hi,

You probably get a response in the first request that you need to add to the headers of the second request.

Maybe, but when i execute this statements in the same browser tab it works, so i think it has nothing todo with headers. 

Or how to find this out?

Erwin is correct. Try logging response headers:

Code:

123

url = ... res, code, hdrs, stat = socket.http.request(url) log(hdrs)

Logged headers should contain "set-cookie" field which then should be parsed and passed as "cookie" header to next request. This post has a similar example though first request is different since login token is in response JSON body: https://forum.logicmachine.net/showthrea...74#pid5774

Thanx admin and Erwin

This it the hdrs output:
* table: [set-cookie] * string: SESSION=23136A000858325C; [content-type] * string: text/plain

So then you just need to pass cookie header to the next request:

Code:

123456789101112131415161718192021222324252627

require('socket.http') socket.http.TIMEOUT = 5 url1 = ... url2 = ... res, err, hdrs = socket.http.request(url1) if res then   tbl = {}   res, err = socket.http.request({     url = url2,     headers = {       cookie = hdrs['set-cookie']     },     sink = ltn12.sink.table(tbl),   })   if res then     resp = table.concat(tbl)     log(resp)   else     alert('request 2 failed: ' .. tostring(err))   end else   alert('request 1 failed: ' .. tostring(err)) end

Yeah, thanks it works!!
