Javascriptlet for parsing Geolocation information from Azure Maps API HTTP Request

Question

I am trying to build a button widget with Tasker that, when pressed, speaks the current user's location in format of Street name and number (for visually impaired people).

Among other, I set up an HTTP Request that uses the retrieved user location and makes a Reverse Address search to Azure Maps API: https://atlas.microsoft.com/search/address/reverse/json?api-version=1.0&subscription-key=[subscription-key]&query=%gl_latitude,%gl_longitude

This returns the following JSON (defined as http_data within Tasker):

{
    "summary": {
        "queryTime": 34,
        "numResults": 1
    },
    "addresses": [
        {
            "address": {
                "buildingNumber": "1433",
                "streetNumber": "1433",
                "routeNumbers": [],
                "street": "Avenue of the Americas",
                "streetName": "Avenue of the Americas",
                "streetNameAndNumber": "1433 Avenue of the Americas",
                "countryCode": "US",
                "countrySubdivision": "NY",
                "countrySecondarySubdivision": "New York",
                "municipality": "New York",
                "postalCode": "10019",
                "municipalitySubdivision": "Manhattan",
                "country": "United States",
                "countryCodeISO3": "USA",
                "freeformAddress": "1433 Avenue of the Americas, New York, NY 10019",
                "boundingBox": {
                    "northEast": "40.765687,-73.976240",
                    "southWest": "40.765012,-73.976714",
                    "entity": "position"
                },
                "extendedPostalCode": "10019-1532",
                "countrySubdivisionName": "New York",
                "countrySubdivisionCode": "NY",
                "localName": "New York"
            },
            "position": "40.765450,-73.976410",
            "id": "IjKZF6illVLFN65JULL_5w"
        }
    ]
}

Now, what I need is to extract only the value streetNameAndNumber from this information for which I used a Javascriplet action but it fails to extract the field.

This extracted information should be identified and defined as variable that I can name in a Say action (%streetNameAndAddress) so it speaks it loud for the user.

I tried a few different options of code but all failed as the info doesn't return and identify the field as information. An example:

var data = JSON.parse(global('http_data'));
var streetNameAndAddress = data.addresses[0].address.streetNameAndNumber;

When executing is like it doesn't define the variable properly and the Say action returns plain "%streetNameAndAddress".

What would the correct code be?

Thank you for your help and apologies for any wrong terminology usage--I have literally zero xp with Coding.

I understand you're trying to build a button widget with Tasker that speaks the current user's location using the Azure Maps API. You're facing an issue with extracting the streetNameAndNumber from the JSON response of the Azure Maps API.

Based on the JSON structure you provided and the code snippet you've tried, it seems like your approach is mostly correct. However, if the Say action returns plain %streetNameAndAddress, it indicates that the variable might not be set correctly in Tasker.

Here's a revised version of your JavaScript code:

var data = JSON.parse(global('http_data'));
if (data && data.addresses && data.addresses.length > 0) {
    var streetNameAndAddress = data.addresses[0].address.streetNameAndNumber;
    setGlobal('streetNameAndAddress', streetNameAndAddress);
} else {
    setGlobal('streetNameAndAddress', 'Location not found');
}

In this code, I'm first checking if data, data.addresses, and data.addresses[0] are valid before trying to access streetNameAndNumber. This is to prevent any potential errors if the data structure is not as expected. Then, I'm using setGlobal to set the Tasker global variable %streetNameAndAddress.

Please ensure that:

1. The http_data variable in Tasker correctly contains the JSON response from the Azure Maps API.
2. The setGlobal function is correctly used to set a global variable in Tasker. Replace setGlobal with the appropriate method if it differs in your version of Tasker.

If you're still facing issues, double-check the JSON response structure to ensure it matches the path you're using to access streetNameAndNumber. Also, make sure that the Tasker JavaScriptlet environment correctly interprets and executes the JavaScript code.

I hope this helps you in getting the desired functionality working. If you have any further questions or run into more issues, feel free to ask!
