为aws lambda函数传递查询参数

我正在尝试设置一个Lambda函数，该函数将提取传递到创建的API网关URL中的查询参数。（边栏：在编程方面，我仍然很幼稚，所以请原谅我无意中对如何命名感到困惑）。我已经使用Synchronize.JS在光纤中封装了一些REST调用，当我将要传递的变量硬编码到各种RESTurl中时，它非常有效，但我们的目标是能够传递不同的参数，这些参数将作为正在进行的不同REST调用的全局变量。这就是我目前拥有的。。。

// Dependendies
var request = require('superagent');
var sync = require('synchronize');

exports.handler = function(event, context) {
    sync.fiber(function() {
        var followingArray = [];
        var followersArray = [];
        var postsCountArray = [];
        var allSqorCountArray = [];
        var trendingPostAuthorArray = [];
        var hashtagCountArray = [];
        var notificationCountArray = [];
        var getParam = function(query){
                var SearchString = window.location.search.substring(1);
                var VariableArray = SearchString.split('&');
                for(var i = 0; i < VariableArray.length; i++){
                var KeyValuePair = VariableArray[i].split('=');
                if(KeyValuePair[0] == query){
                    return KeyValuePair[1];
                }
                };
        };
        var userId = getParam('userId');
        var limit = getParam('limit');
        var offset = getParam('offset');
        var restCallOne = function() {
            request('https://someurl.com/etc/' + userId + '/follows?limit=' + limit + '&offset=' + offset)
            .end(function(err, res) {
                if (err) {
                    console.log('Request 1');
                    context.fail("Danger Will Robinson!!! Follows Count Does Not Like You!!");
                } else {
                    var followsCount = res.body.total_count;
                    followingArray.push(followsCount);
                }
            });
        };
        var restCallTwo = function() {
            request
            .get('https://someurl.com/etc/etc/etc?limit=' + limit + '&offset=' + offset)
            .set({'access-token': 'someAccessToken'})
            .end(function(err, res) {
                if(err) {
                    console.log('Request 4');
                    context.fail("Danger Will Robinson!!  The All Sqor Feed is moody");
                } else {
                    var allSqorCount = res.body.total_count;
                    allSqorCountArray.push(allSqorCount);
                }
            });
        };
        var restCallThree = function() {
            request
            .get('https://someUrl.com/etc/' + userId + '/followers?limit=' + limit + '&offset=' + offset)
            .end(function(err, res) {
                if (err) {
                    console.log('Request 3');
                    context.fail("Danger Will Robinson!!! Following Count Done Smacked You Upside The Head!!");
                } else {
                    var count = res.body.total_count;
                    followersArray.push(count);
                    context.done(null, 'The total number of people that follow Andy is ' + followersArray[0] +
                                       ', and the number of people that Andy follows is ' + followingArray[0] + 
                                       ', and the number of posts in his feed is ' + allSqorCountArray[0]);
                }
            });
        };
        try {
            restCallOne(userId, limit, offset);
        } catch(errOne) {
            console.log("Error on call 1!!");
        }
        try {
            restCallTwo(limit, offset);
        } catch(errTwo) {
            console.log("Error on call 2!!");
        }
        try {
            restCallThree(userId, limit, offset);
        } catch(errThree) {
            console.log("Error on call 3!!");
        }
    });
};

当我将其与此函数链接时生成的API网关URL如下：https://someID.execute-api.us-east-1.amazonaws.com/syncFunctionalParams

但我希望能够传入这样的内容，并使用Lambda函数中的params从其余调用中返回正确的信息：https://someID.execute-api.us-east-1.amazonaws.com/syncFunctionalParams?userId=212733&limit＝25&偏移=0

这可能吗？？我是不是偏离了轨道？
