Title: Can't get cookies working
Post by: cormullion on October 05, 2007, 07:22:33 AM
I can't get cookies working. The code I have is this:


Code Select
(load "...cgi.lsp")
(CGI:set-cookie "password" "secret" "asite.com" "/somedir")

(print "Content-type: text/htmlnrnr")


If I swap these two lines round, I can see the password/secret/asite stuff at the top of the page, but when they're the right way round no cookies are sent.



Any ideas for getting it working?

What about ending the line with rnrn instead of nrnr?  Does that make a difference?  (I'm not trying to be cute, I just am not in a position to test that.)

Also, is it possible to load the file ...cgi.lsp?  I mean three dots, then cgi.lsp?  While it is possible to name a file this way, it might not be what you meant.

Yes, that was just shorthand - I didn't put the full path of cgi.lsp in, since I've got it stored somewhere else. But I think it's working OK - the rest of the CGI stuff is working fine... Just can't get any cookies to appear.

Oh, sorry about that.  Well, I guess that leaves me tapped.  :-(

Here is a small working cookie example:



http://newlisp.org/code/cookie.cgi



The first time you go to the page it will say "No cookie found", the second time it will show the cookie.



here the source:


Code Select
#!/usr/bin/newlisp

(load "cgi.lsp")

(CGI:set-cookie "key" (uuid) "newlisp.org" "/code")

(print "Content-type: text/htmlrnrn")

(if (CGI:get-cookie "key")
(println "<h2>Cookie found:" (CGI:get-cookie "key") "<h2>")
(println "<h2>No cookie found</h2>"))

(exit)

ps: for an example using cookie expiration time see the calendar application on the http://newlisp.org/index.cgi?Code_Contributions page

As I feared, it's not the cookie code, but something else. Your example works fine, but when copied to another place produces the error:


Code Select
list expected in function lookup : cookies called from user defined function CGI:get-cookie

There was a problem in cgi.lsp v.2.1 and earlier when '=' signs where present in the cookie key or value string. This has been fixed in cgi.lsp version 2.2 distributed since 9.2.1.



What version of cgi.lsp are you using?



Lutz



ps: 'cookies' is a variable local to the CGI name space as CGI:cookies and set to '() if no cookies are present.

Ah - your file doesn't work when copied to the server - says 'no cookie found' each time. So presumably there's something on the server that's preventing it working...



Edit: i now suspect that the expiry date is compulsory. Will investigate.



Edit: I think its working. Domain name had two dots perhaps.
