Introduction

This is a wrapper around qs package, made in order to create a querystring conforming to Google Digital Signature , by simply adding your signature key as the signature parameter, see Usage below.

It's especially intended as an almost drop'in replacement for qs package or querystring node API in packages such as :

• google-distance-matrix

• google-distance

• googleMapsUtil

Install

$> npm install qs-google-signature

Usage

var qs = require('qs-google-signature');

var query = {
  address: "New+York",
  client: "clientID",
  signature: "vNIXE0xscrmjlyV-12Nj_BvUPaw=" //this is the signature key provided by Google
}

var queryString = qs.stringify(query, url);
//=> address=New%2BYork&client=clientID&signature=WrTAou0zgXHjKwUPdsITPZeMXew=

Debug

To display logs, thanks to debug use the environment variable "DEBUG" to set that you want to display "qs:signature" logs, e.g. :

$> DEBUG="qs:signature" node myProgram.js

It can also be listed among other things to debug:

$> DEBUG="http,qs:signature,worker" node myProgram.js
