Errors returned from Web requests

Former Member over 9 years ago

Hi there,

I am trying to fix an app that uses the Communications module and gets some json data from a website. I've had a user say that they get an error -300 on their Fenix5X, but I am not sure if this just that the API needed a boot. They then reported getting error -400. I'm now having a look at the widget and I get error -400 on my watch (VivoActive) for this site,
The errors mean as follows: NETWORK_REQUEST_TIMED_OUT = -300 INVALID_HTTP_BODY_IN_NETWORK_RESPONSE = -400
If I access the API the data seems to be formed fine - here is an example of the data that I get. The app also seems to work OK in the simulator which reckoned 26.8/58kB
{"status":[{"now":1507746978061}],"bgs":[{"sgv":"120","trend":5,"direction":"FortyFiveDown","datetime":1507746187255,"filtered":135104,"unfiltered":129088,"noise":1,"bgdelta":-5,"iob":"1.01","bwp":"-1.01","bwpo":-7487}],"cals":[{"slope":849.377297763804,"intercept":26812.094971367154,"scale":1}]} Has anything changed with how you have to consume json data and manipulate it in the last few months?

Thanks,

In the sim, what's the peak memory (file->view memory)? what changed since you starting having problems? New GCM or something? Is it with iOS, Android, or both?

maybe post your makeWebRequest

Hi Jim,

Thanks for the reply.

The peak memory is 29.2kB so nothing excessive. I think that only time has passed since I started having problems, which comes with it new GCM apps, and watch updates I guess. My phone is Android running Nougat and my watch is a VA with Connect iQ 1.4.2. The other person's is a Fenix5X but I don't know what phone. The slightly odd thing is that I have an app that is analogous to my widget and that is working for the site, but the widget isn't working.
This is how I do my makeWebRequest:

sys.println ("setting the URL from application properties");
url = "https://" + apprun.getProperty("sitename") + apprun.getProperty("hostdomain") + "/pebble";
**** quite a lot of other code****
if (currentsettings.phoneConnected) {
globalText = "Loading\n....";

comms.makeWebRequest(url ,{"units"=>propunits} ,{"Content-Type"=>comms.REQUEST_CONTENT_TYPE_JSON} ,method(:onReceive));
sys.println ("Receiving");
}
else {
globalText = "Phone not\nconnected";
}
// then I have an onReceive method that does this:
function onReceive(responseCode, data)
{

globalText = "data here";
Ui.requestUpdate();
sys.println ("Receiving data");
if( responseCode == 200 )
{

if (data["bgs"].size()!=0) {

gotData = true;
// even more code in the what to do if the responseCode is 200
}
else{
sys.println("No BG data");
globalText = "No BG data";
}
}
else if (responseCode == -2){
globalText = "No internet\nconnection";
}
else {
globalText = "Website\nError: " + responseCode.toString();
}

// ///////////////// end of code sample - what I then do is display the globalText on the watch face, so normal people get the error returned from the web request.
