A question on HTTPRequest

Hey guys, I've been having some oddness happening with my HTTPRequest calls and I'm figuring it must just be something that I'm doing wrong. Lemme post my function call:

requestid = llHTTPRequest(URL, [HTTP_METHOD, "POST", HTTP_MIMETYPE, "application/x-www-form-urlencoded"], "";

The oddness is that just last night this started working (it didnt originally), and this morning when I tried it again, "The requested URL could not be retrieved". URL is the url of the php script followed by a list of &key=value pairs. I'm dumping the string to chat right before the call and when I manually put it into my web browser it works fine. So am I doing something wrong here?

What HTTP status code are you getting back in the http_response() event handler?

Also, check your web server logs to see if they show the access.

Ah ok, after some messing around I at least determined that its an issue with the webserver, since I can access pretty much anything else besides my own address. The status code I get is 503 - Service Unavailable. I can't seem to find the attempts in the access logs either. Any ideas why it would flash me that error on an httprequest but work fine in a browser?

I'm not an expert in the HTTP protocol, but you aren't actually posting anything. Perhaps your program/webserver is upset that you're effectivly posting a form with no data?

im certainly no expert in this area... but doesnt POST data go in the body?

anyone got an example of a working POST lsl script, Im having problems getting it to work... and not sure if im screwing up the LSL or php end of things.

I am just starting with LSL, but I have this working:

key myRequestId;

default
{
    touch_start(integer number)
    {
        myRequestId = llHTTPRequest(
            "http://www.example.com/2L.php",
            [HTTP_METHOD, "POST", HTTP_MIMETYPE, "application/x-www-form-urlencoded"],
            "param=test"
        );     
    }
    
    
    http_response (key request_id, integer status, list metadata, string body) {
        if(request_id == myRequestId) {
            llWhisper(0, body);
        }
    }
}

If you are manually entering the URL into the address bar of your browser, you are performing a HTTP GET, not POST. Try changing that.

thanks Chambers,
i did get it solved with a little help from a friend - though you beat me to putting a solution example up.

i might have done better if i hadnt inserted stupid typos along the way...

Man Pete I wish you had caught this thread earlier, took me a while to figure that out on my own hehe. Thanks for the reply.

is it possible to put the http_response in a function?

I want to call the function from a dialog.

You can put "llHTTPRequest(...)" in a custom function, but not the actual "http_response" event handler.

You cannot 'call' http_responce, its an event handler. You dont know when , or even if, you will get a responce. You just have to wait for it to arrive.

Do you mean you want to display the results in a dialog? Just call llDialog from within the http_responce handler once you have the data.

ah ok. thanks.
