IBM Worklight - Adapter procedure response returns "zero results" from Google Places

Question

I am getting status "ZERO RESULTS" when I invoke HTTP Adapter using Indian latitude and longitude to search for any service like food, malls etc.

Here is my adapter implementation:

 function getGooglePlaces(location,name) {

    var input = {
        method : 'get',
        returnedContentType : 'json',
        path : 'maps/api/place/search/json',
        headers: {
            Host: 'maps.googleapis.com'
        },
        parameters : {
            'key'       :   My Key,
            'location'  :  location,
            'radius'    :   '10000',
            'sensor'    :   'false',
            'name'      :  name 
        }
    };

    var response = WL.Server.invokeHttp(input); 
    return response;

}

}

The JSON response for indian coordinates.
results is the array of places searched

Answer 1

I have used the following and got a valid response, using a Worklight adapter.

• Note that I passed name and location as part of the parameters object and not like you did (just for the sake of simplification)
• I added a type parameter for "restaurant"
• I increased the radius

With the above, I got results.
Looks to me like this is a matter of tweaking the request parameters. Nothing related to Worklight adapters here, as it works.

GooglePlaces-impl.js

function getPlaces() {
    var input = {
            method : 'get',
            returnedContentType : 'json',
            path : 'maps/api/place/search/json',
            headers: {
                Host: 'maps.googleapis.com'
            },
            parameters : {
                'key'       : 'make-sure-to-place-here-your-SERVER-KEY-generated-by-Google-GCM-console',
                'location'  : '27.173033, 78.042133',
                'radius'    : '30000',
                'sensor'    : 'false',
                'name'      : 'Taj Mahal',
                'type'      : 'restaurant',
            }
        };

        var response = WL.Server.invokeHttp(input);
        return response;
}
