makeRequest does not call method(:onReceive) in background / WF

post your code for the actual makeWebRequest.

If you want to trigger the background, in the sim use Simulation>Background Events

thanks, i 'll test the simu /BG Events Asap !

Here is the code 

    function makeRequest(Stock_symbol) {
Sys.println("in makerequest : " + Stock_symbol);      
      symbol= "&symbol=" + Stock_symbol;
      var params = {};
   var headers = {"Accept" => "application/json" };
      var options = {
    :method => Comm.HTTP_REQUEST_METHOD_GET,
    :headers => headers,
    :responseType => Comm.HTTP_RESPONSE_CONTENT_TYPE_JSON
   };
   var responseCallback = method(:onReceive);
         w3Api += interval + output_size + symbol + api_key ;
   if (Comm has :makeWebRequest ) {
    Comm.makeWebRequest(w3Api, params, options, responseCallback);
    Sys.println(" Comm has :makeWebrequest , full url = " + w3Api );
   }
   else {
    Comm.makeJsonRequest(w3Api, params, options, responseCallback);
    Sys.println("in Jsaonrequest = " + w3Api );
   }
   
   
     }

and the onReceive :

     function onReceive(responseCode, data) {
Sys.println("in onReceive------------------");     
         if (responseCode == 200) {
             return (data);
         } else {
             return ("Failed to load\nError: " + responseCode.toString());
         }
     }

You want to make use of params and not put everything in the url.  Not sure why that would prevent the callback, outcoile cause an issue.  Here for example, is how I do things when getting weather data, and you see how things like lat,lon, etc are included.

	    	var UNITS=(Sys.getDeviceSettings().temperatureUnits==Sys.UNIT_STATUTE) ? "imperial" : "metric";
			var url="https://api.openweathermap.org/data/2.5/weather";
	    	var param={
	    		"lat" => latlon[0].toFloat(),
	    		"lon"=>latlon[1].toFloat(),
	    		"appid"=>APIKEY,
	    		"units" => UNITS};
			var options = {
				:methods => Comm.HTTP_REQUEST_METHOD_GET,
				:headers => {"Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED},
				:responseType => Comm.HTTP_RESPONSE_CONTENT_TYPE_JSON
			};
   	
			Comm.makeWebRequest(
	    	   	url,
	    	   	param,
	    	   	options,
	    	   	method(:receiveWeather));

Just 'cos i tried to put in params and so after i wanted to be sure it was not the cause of Something wrong...

i also tried to put method(:onReceive) instead of responseCallback but no way...

(just try Simu BG events, i didn't find the app running in target!)

Are you sure the background itself is every running?  Do you see any println calls from it in the console?

(

WebStockRequestServiceDelegate is the class in bg :

" (:background)
class WebStockRequestServiceDelegate extends Toybox.System.ServiceDelegate
{

"

)

may it be an error here ?

function getServiceDelegate(){
     var now=Sys.getClockTime();
     var ts=now.hour+":"+now.min.format("%02d");   
     Sys.println("getServiceDelegate: "+ts);
        return [new WebStockRequestServiceDelegate()];
    }

or here (end of WebStockRequestServiceDelegate)

    function initialize() {
  Sys.ServiceDelegate.initialize();
  inBackground=true;    //trick for onExit()
var now=Sys.getClockTime();
var ts=now.hour+":"+now.min.format("%02d");
Sys.println("bg init: "+ts);  
  
 }
 
    function onTemporalEvent() {
     var now=Sys.getClockTime();
     var ts=now.hour+":"+now.min.format("%02d");
        Sys.println("onTemporalEvent: "+ts);
       
        //just return the timestamp
//      var msg_value = makeRequest(Stock_symbol);

      var msg_value ="test";

        makeRequest(Stock_symbol);
Sys.println("onTemporalEvent exit after makeRequest: "+ts+ " retour web=" + msg_value);       
        Background.exit(msg_value);
    }
      

??

thanks

(Excuse my poor English language and delay for answering from France, it's 11PM here …St Tropez nearby)

Wow ! how to thanks you ? Merci !! So much !!!

I was pretty sure the callback was immediatly called by makeRequest ( thought they were linked as one and  "unique" function).

By now, the bg.exit is going to stop the callback, before the return()?

So i suppose no need anymore of the return, eventually just put a "N/A" string in data if responsecode is != 200?

or adding a parsing function and put the bg.exit() in...

It works fine now. I'm going to clean my code...

thank you

;-)

As you could have seen, i am largely inspire by your work, your examples, and your tutos (like the Guest post about BG, like your app vsbgwf). So thank you very much for all the job you do here (with some others pretty good guys). Thank you for the time you give to all of us in need of such help !
