Re: [Long] Moving a REST request from Desktop to Server
+1 Andre -
curl is definitely your friend for simple LC-server to other server
communication. I maintain a server app that uses it to interact with the
Vimeo server.

The merge function is similar, but just different enough to prevent us from using it to test LC Server scripts in the LC IDE. :( If anyone else here would find that useful perhaps I could submit a request for that. I'm thinking maybe something like: put merge( tSomeStuff, "server") into tModifiedStuff ...where "server" is a flag that determines which merge style should be used. Or would it be simpler as a separate function, maybe something like: put serverMerge( tSomeStuff ) into tModifiedStuff Suggestions on that? It would be so nice if we could find some way to overcome the incompatibilities between LC Server and how LC normally handles scripts so we could debug as we write (the xTalk way!). -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: [Long] Moving a REST request from Desktop to Server
A how-to for using standalones as CGI's is a fantastic idea! I've spent hours trawling through the mailing list archives for a definitive set of instructions on how to set this up but could never string together enough fragments of information to get it working.

Re: [Long] Moving a REST request from Desktop to Server
Hi Richard, no, I did not considder using a standalone as a CGI engine. I am in a rather difficult environment with the project (government servers that have ridiculous tests and approval times for changed solutions). On top of that, I would not want to lose the benefit of using liveCode PHP style. For most of what I do with LC server I am perfectly happy with the way it works. However, not having some stuff that libURL offers available (even though the dictionary states otherwise, in the case of libURLLastRHHeaders, Platforms desktop, server). Technically it should be possible if the Server script does a POST to a remote Server to see the RAW response in some form. In my case this would help a lot. I built quite a nice Framework (at least it works quite well for me) around the Server engine and it would be quite labor intense to change what I have. The only option I would see, would be moving the WEBSERVICE request into my LC Desktop client, which is what I’d rather avoid… :-( Cheers, Malte ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Standalones can be run facelessly with a -ui flag, and while they require a one-time cost to set up a library to read stdin and parse the request and env vars, once you're set up you get something LiveCode Server can't offer: complete compatibility with the LiveCode Script desktop syntax. LC Server is great for many things, but since it doesn't work like LC on the desktop I don't use it for anything beyond testing. I need to debug, and by not using the Server engine I can run my scripts right in the IDE. Last week I was going to put together some notes on this to make using LC standalones as CGIs easier, but as luck would have it I couldn't get either Server or a standalone running as a CGI on either of my shared hosting accounts, for reasons that appear to be related to the RAM requirements from font loading: http://quality.livecode.com/show_bug.cgi?id=14115 I have a workaround for that (thanks to some clever assist from Peter Brett and Mark Waddingham), but it's kinda funky and non-obvious to set up, so while it might work okay for me once in a while it's not the sort of thing I want to tell other people is reflective of how we do things in the LC world. We are, after all, about simplicity, or at least strive for it. But if you're on a VPS (about half our users are*) perhaps we can continue this discussion and explore simple means of using standalones as CGIs. It really is a much simpler overall workflow once you get it going. * I ran this survey on the LC forums - if you haven't voted please chime in on how you use LC on servers: POLL: LiveCode Server deployment http://forums.livecode.com/viewtopic.php?f=15=26772 -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
[Long] Moving a REST request from Desktop to Server
Hi all,
I am trying to move a request I do from a desktop app to a liveCode server
script and am facing the problem that some of the stuff I use (most of it
libURL stuff) is not available on the server. Now I wonder how I could
translate it…
Scenario is the following:
Problem is libURLLastRHHeaders() is unavailable on server and can not easiely
be copied from libURL
Anyone got an idea?
local sCookieHeader
on mouseUp
local tURL,tUser,tPassWord,tCookie,tSubmitId,tsubmit,tJson,tJsonArray
local test
try
set the httpHeaders to empty
put „aUser" into tUser
put „aPassword" into tPassWord
put "264812" into tSubmitID
put "Log+in" into tSubmit
get libURLFormData("userName", tUser,"password",
tPassword,"submit",tSubmit,"submitID",tSubmitId) — not available on Server, but
can be copied from libURL
post it to url "http://test.com/login.php;
_storeCookies libURLLastRHHeaders() — needed to authenticate.
libURLLastRHHeaders unavailable
set the httpHeaders to sCookieHeader
put fld "URL" into tURL
put URL tURL into tJson
catch theErr
put theErr
end try
end mouseUp
## Parse header returned from a server and create a cookie header that
## can be sent back: Cookie: cookie1;cookie2;cookie3;...
private command _StoreCookies pHeader

put lineoffset("Set-Cookie:", pHeader, theOffset) into theLineNo

put line theLineNo of pHeader into theCookieLine

put offset(";", theCookieLine) into theCharNo
if theCharNo > 0 then
delete char theCharNo to -1 of theCookieLine
end if
put theCookieLine & ";" after sCookieHeader
put theLineNo into theOffset
else
exit repeat
end if
end repeat
if the last char of sCookieHeader is ";" then
delete the last char of sCookieHeader
end if
if sCookieHeader is not empty then
put "Cookie: " before sCookieHeader
end if
return empty
end _StoreCookies
