How to make HTTPS requests with serverside javascript using Worklight?

Solved javascript https google-places-api ibm-mobilefirst

I'm toying around with IBM worklight, and am trying to create an adapter to feed some data in from the Google places API.

I want to call this URL :

https://maps.googleapis.com/maps/api/place/search/json?key=AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM&location=52.0700,1.1400&radius=10000&sensor=false&name=coffee

Executing this URL works fine in a browser, and displays some nice JSON that I'm trying to obtain via Worklight.

The Worklight adapters are created in Javascript, this is what I have so far :

function getCoffeeHouses() {

    var input = {
        method : 'get',
        returnedContentType : 'json',
        path : 'maps/api/place/search/json',
        parameters : {
            'key'       :   'AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM',
            'location'  :   '52.0700,1.1400',
            'radius'    :   '10000',
            'sensor'    :   'false',
            'name'      :   'coffee' 
        }
    };

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

 // Extract latitude and longitude from the response.
    var type = typeof response; 
    if ("object" == type) {
        if (true == response["isSuccessful"]) {
            // Return JSON object with lat and lng.
            return response["results"];
        } 
        else {
            // Returning null. Web request was not successful.
            return null;
        }
    } 
    else {
        // Returning null. Response is not an object.
        return null;
    }
}

And this is the result that I get in the console, when I test the above:

Failed to parse JSON string

I think, that this is probably caused because the adapter is requesting as HTTP, whereas it should be using HTTPS.

If I alter the request to use HTTP in a browser, it displays similar results.

Question : Can I make an HTTPS request by altering the above Javascript, or am I misunderstanding worklight adapters?

Looks like googleapis will not work if you don't specify Host header inside of your request. After adding it everything works as it should:

This is adapters's XML section

<connectivity>
    <connectionPolicy xsi:type="http:HTTPConnectionPolicyType">
        <protocol>https</protocol>
        <domain>maps.googleapis.com</domain>
        <port>443</port>            
    </connectionPolicy>
    <loadConstraints maxConcurrentConnectionsPerNode="2" />
</connectivity>

This is adapter's JS:

function doGet() {

var input = {
    method : 'get',
    returnedContentType : 'json',
    path : 'maps/api/place/search/json',
    headers: {
        Host: 'maps.googleapis.com'
    },
    parameters : {
        'key'       :   'AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM',
        'location'  :   '52.0700,1.1400',
        'radius'    :   '10000',
        'sensor'    :   'false',
        'name'      :   'coffee' 
    }
};

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

}

i too have a similar problem.. i mentioned all most all content types but its not working at all.. – Maintop 11/3, 2013 at 8:5

The error description is "The server refused this request because the request entity is in a format not supported by the requested resource for the requested method (Unsupported Media Type)" .... i have specified the Content-Type : 'application/json'.. but still the issue presist.. – Maintop 11/3, 2013 at 8:9

in your adapter there is also an {ADAPTER NAME}.xml

In it, under connectivity under connectionPolicy, there is the protocol. did you change it to https and deploy?
