Accessing HTTP Services

AM passes an HTTP client object, httpClient, to server-side scripts. Server-side scripts can call HTTP services with the httpClient.send method. The method returns an HttpClientResponse object.

Configure the parameters for the HTTP client object by using the org.forgerock.http.protocol package. This package contains the Request class, which has methods for setting the URI and type of request.

The following example, taken from the default server-side Scripted authentication module script, uses these methods to call an online API to determine the longitude and latitude of a user based on their postal address:

function getLongitudeLatitudeFromUserPostalAddress() {

    var request = new org.forgerock.http.protocol.Request();

    request.setUri("http://maps.googleapis.com/maps/api/geocode/json?address=" + encodeURIComponent(userPostalAddress));
    request.setMethod("GET");

    var response = httpClient.send(request).get();
    logResponse(response);

    var geocode = JSON.parse(response.getEntity());
    var i;

    for (i = 0; i < geocode.results.length; i++) {
        var result = geocode.results[i];
        latitude = result.geometry.location.lat;
        longitude = result.geometry.location.lng;

        logger.message("latitude:" + latitude + " longitude:" + longitude);
    }
}

HTTP client requests are synchronous and blocking until they return. You can, however, set a global timeout for server-side scripts. For details, see Scripted Authentication Module Properties.

Server-side scripts can access response data by using the methods listed in the table below.
