Can a WatchFace Make Several WebRequests?

Former Member over 7 years ago

I can successfully make one WebRequest using a WatchFace, but I'd like to make *several* WebRequests. Is it possible? Here is what I have tried so far (unsuccessfully):
1) In onTemporalEvent, I made several calls to makeWebRequest specifying the same onRecieve callback.
2) In onTemporalEvent, I made several calls to makeWebRequest specifying *different* onRecieve callbacks.
3) In getServiceDelegate, I returned an array of several ServiceDelegate instances.

I've tried that I can extract both in onBackgroundData and get correct data with receivedData[0] and receivedData[1], but how to make them as one JSON object that would be saved into storedData?

The way I do this in in onReceive1 and onReceive2, I do

if(responseCode!=200) { Bg.exit(responseCode);}

And in onReceive2, do

Bg.exit([res1,res2]);

if there isn't an error

then in onBackgroundData(data)

if(data instanceof Number) {//got an error}

else {//got good data}

if there was an error, you'll likely see null for data when onReceive1 and onReceive2 is called

Thanks jim_m_58... I try to explain me a little better.
I get the data correctly like you described Bg.exit([res1, res2]);

The problem is that res1 and res2 are two separate json objects. How do I save them like one (concatenate them) or similar?

(:background_method)
function onBackgroundData(data) {
    var pendingWebRequests = getPendingWebRequest();	
	var type = data.keys()[0]; // Type of received data.
	var storedData = getProperty(type);
	var receivedData = data[type]; // The actual data received: strip away type key.
	
	var data1 = receivedData[0]; // res1 as JSON object
	var data2 = receivedData[1]; // res2 as JSON object
	
	storedData = HOW TO PUT BOTH JSON OBJECTS HERE;	
	pendingWebRequests.remove(type);
	setProperty("PendingWebRequests", pendingWebRequests);
	setProperty(type, storedData);
	Ui.requestUpdate();
	
}

HOW TO PUT BOTH JSON OBJECTS HERE - how to store both? ^

Technically, data1 and data2 are Monkey C dictionaries which (recursively) contain dictionaries, arrays, numerical types and booleans. (They were JSON objects in the network response, but makeWebRequest() converted them into the corresponding Monkey C types.)

You can't really concatenate dictionaries (or JSON objects for that matter), but you can put 2 dictionaries in an array (as they already are in your code) and store the array.

e.g.

storedData = receivedData;

However, it looks like you want a solution where you're storing a dictionary. You can achieve that by creating a new dictionary with data1 and data2 as values.

storedData = {
:data1 => data1,
:data2 => data2
};

In this example, :data1 and :data2 can be replaced with the symbols of your choice.

You should avoid to call several WebRequests one after the other because strange errors appear. So good solution is paring WebRequests - onRecive, WebRequests - onRecive...
