Send Multiple Http Request Via Parse.cloud.httpreq

I'm trying to send multiple HTTP Requests via Parse.Cloud.httpRequest but I get {'code':141,'message':'Error: Can't call success/error multiple times I need to do all requests a

Solution 1:

The trick is to collect promises to complete the http requests, then set the response "when" the promises are complete.

Parse.Cloud.define('http', function(request, response) {
    var promises = [];

    for (var i = 0; i < request.params['params'].length; i++) {
        var object = request.params['params'][i];
        promises.push(makeRequestWithObject(object));
    }
    Parse.Promise.when(promises).then(function() {
        // results are passed to this function as var args
        response.success(arguments);
    }, function(error) {
        response.error(error);
    });
});

// return a promise to complete an http request with object
function makeRequestWithObject(object) {
    var url = 'http://185.xxxxxxx'+ object +'&languagePath=en';
    return Parse.Cloud.httpRequest({ url:url });
}
