Sample script for persistent URL using Gridurl

Grid URL Persister (gridurl.appspot.com) was created by Latif Khalifa to make work with http-in easier. Here's a sample script that shows how to use Gridurl.

<lsl> // Go to http://gridurl.appspot.com/random and copy the UUID // that will be generated, then paste it below. string gridurl_key="CHANGE-ME";

// This message will be seen by users on the web page after // they send their message, so you may want to customize it: string risposta = "Thanks! Please use the button in your browser to go back.";

// --------------------------------------------------- string gridurl_indirizzo = "http://gridurl.appspot.com/go/"; string baseurl = "http://gridurl.appspot.com/reg?service="; key mykey; string url; string query; key requestid;

setup() {

   url = "";
   llRequestURL();

}

// risponde via HTTP send_response(key id, string body) {

   llHTTPResponse(id, 200, risposta);

}

// http://gridurl.appspot.com/ update_gridurl(string testo) {

   query = gridurl_key + "&url=" + llEscapeURL(testo) + "/";
   requestid = llHTTPRequest(
   baseurl + query,
   [HTTP_METHOD,"GET", HTTP_MIMETYPE,"application/x-www-form-urlencoded"],
   "");    

}

action(string query) {

   if(query == "luce")
   {
       llSetPrimitiveParams([PRIM_GLOW, ALL_SIDES, 0.1]);
       llSetPrimitiveParams([PRIM_GLOW, ALL_SIDES, 0.0]);        
   }
   // DEBUG:
   // llSay(0, query);

}

default {

   state_entry()
   {
       mykey = llGetOwner();            
       setup();        
   }
   
   on_rez(integer n) 
   {
       setup(); 
   }

   changed(integer c)
   {
       if (c & (CHANGED_REGION | CHANGED_REGION_START | CHANGED_TELEPORT) )
       {
           setup();
       }
   }

// scatta in risposta a setup() cioe' alla richiesta di un nuovo URL

   http_request(key id, string method, string body)
   {
       // ci e' stato correttamente assegnato un nuovo URL
       if (method == URL_REQUEST_GRANTED)
       {
           url = body;
           // DEBUG:            
           // llOwnerSay(" nuovo url = " + url);                   
           update_gridurl(url);            
       }
       
       else if (method == URL_REQUEST_DENIED)
       {
           llInstantMessage(mykey, "Something went wrong, no url. " + body);
       }
       // lo script e' stato richiamato (da un browser, cliccando su un link...)
       else if (method == "GET")
       {
               string query = llGetHTTPHeader(id, "x-query-string"); 
               // DEBUG:
               // llInstantMessage(mykey, "query = " + query);       
               action(query);
               llHTTPResponse(id,200,"OK");
       }
       else
       {
           llHTTPResponse(id,405,"Unsupported method.");
       }
   }

// comunico gli URL dello script

   touch_start(integer total_number)
   {
       if(gridurl_key != "CHANGE-ME")
       {
           llInstantMessage(mykey, "Click to test: " 
           + gridurl_indirizzo
           + gridurl_key
           + "?luce"); 
       }
       else
       {
           llSay(0, "You didn't set the Gridurl key yet. Go to http://gridurl.appspot.com/random and copy the UUID that will be generated, then paste it at the begin of this script."); 
       }
   }
