/* Here's some JavaScript software for implementing OAuth.
exports.OAuth= function(requestUrl, accessUrl, authorizeUrl, consumerKey, consumerSecret, version, signatureMethod) {
this._requestUrl= requestUrl;
this._accessUrl= accessUrl;
this._authorizeUrl= authorizeUrl;

This isn't as useful as you might hope. OAuth is based around
allowing tools and websites to talk to each other. However,
JavaScript running in web browsers is hampered by security
restrictions that prevent code running on one website from
accessing data stored or served on another.
Before you start hacking, make sure you understand the limitations
posed by cross-domain XMLHttpRequest.
On the bright side, some platforms use JavaScript as their
language, but enable the programmer to access other web sites.
Examples include Google Gadgets, and Microsoft Vista Sidebar.
For those platforms, this library should come in handy.

// The HMAC-SHA1 signature method calls b64_hmac_sha1, defined by
// http://pajhome.org.uk/crypt/md5/sha1.js
/* An OAuth message is represented as an object like this:
{method: "GET", action: "http://server.com/path", parameters: ...}
The parameters may be either a map {name: value, name2: value2}
or an Array of name-value pairs [[name, value], [name2, value2]].
The latter representation is more powerful: it supports parameters
in a specific sequence, or several parameters with the same name;
for example [["a", 1], ["b", 2], ["a", 3]].
Parameter names and values are NOT percent-encoded in an object.
They must be encoded before transmission and decoded after reception.
For example, this message object:
{method: "GET", action: "http://server/path", parameters: {p: "x y"}}
... can be transmitted as an HTTP request that begins:
GET /path?p=x%20y HTTP/1.0
(This isn't a valid OAuth request, since it lacks a signature etc.)
Note that the object "x y" is transmitted as x%20y. To encode
parameters, you can call OAuth.addToURL, OAuth.formEncode or
OAuth.getAuthorization.
This message object model harmonizes with the browser object model for
input elements of an form, whose value property isn't percent encoded.
The browser encodes each value before transmitting it. For example,
see consumer.setInputs in example/consumer.js.
*/
/* This script needs to know what time it is. By default, it uses the local
clock (new Date), which is apt to be inaccurate in browsers. To do
better, you can load this script from a URL whose query string contains
an oauth_timestamp parameter, whose value is a current Unix timestamp.
For example, when generating the enclosing document using PHP:
<script src="oauth.js?oauth_timestamp=<?=time()?>" ...
Another option is to call OAuth.correctTimestamp with a Unix timestamp.
