Wiki description

Responds to request_id with status and body.

Function notes

The response need not be made inside the http_request event but if it does not happen in a timely fashion the request will time out (within 25 seconds).

Caveats

  • This call must be made by the script containing the http_request event where the request_id was received.
  • There is no limit, other than script size, to the amount of data that can be sent by this function.
    • llHTTPRequest can truncate the response length in receiving scripts. Be aware when using them together for prim-to-prim communications.
  • The response by default has "content-type: text/plain". Use llSetContentType to optionally return a different type, like "text/html".
  • Besides llSetContentType, there is no way to set any custom HTTP headers in the response.

Examples

string url;

default
{
    changed(integer change)
    {
        if (change & (CHANGED_REGION_START | CHANGED_REGION | CHANGED_TELEPORT))
            llResetScript();
    }

    state_entry()
    {
        llRequestURL();
    }

    touch_start(integer num_detected)
    {
    //  PUBLIC_CHANNEL has the integer value 0
        if (url != "")
            llSay(PUBLIC_CHANNEL, "URL: " + url);
    }

    http_request(key id, string method, string body)
    {
    //  http://en.wikipedia.org/wiki/Create,_read,_update_and_delete
        list CRUDmethods = ["GET", "POST", "PUT", "DELETE"];
    //  it's bit-wise NOT ( ~ ) !!!
        integer isAllowedMethod = ~llListFindList(CRUDmethods, [method]);

        if (isAllowedMethod)
        {
            llHTTPResponse(id, 200, "Body of request below:\n" + body);
        }
        else if (method == URL_REQUEST_GRANTED)
        {
        //  don't forget the trailing slash
            url = body + "/";

            llOwnerSay("URL: " + url);
        }
        else if (method == URL_REQUEST_DENIED)
        {
            llOwnerSay("Something went wrong, no URL.\n" + body);
        }
        else
        {
            llOwnerSay("Ummm... I have no idea what SL just did. Method=\""+method+"\"\n" + body);
        }
    }
}
