/* Simple OAuth
|
|
*
|
|
* This class only builds the OAuth elements, it does not do the actual
|
|
* transmission or reception of the tokens. It does not validate elements
|
|
* of the token. It is for client use only.
|
|
*
|
|
* api_key is the API key, also known as the OAuth consumer key
|
|
* shared_secret is the shared secret (duh).
|
|
*
|
|
* Both the api_key and shared_secret are generally provided by the site
|
|
* offering OAuth services. You need to specify them at object creation
|
|
* because nobody <explative>ing uses OAuth without that minimal set of
|
|
* signatures.
|
|
*
|
|
* If you want to use the higher order security that comes from the
|
|
* OAuth token (sorry, I don't provide the functions to fetch that because
|
|
* sites aren't horribly consistent about how they offer that), you need to
|
|
* pass those in either with .signatures() or as an argument to the
|
|
* .sign() or .getHeaderString() functions.
|
|
*
|
|
* Example:
|
|
<code>
|
|
var oauthObject = OAuthSimple().sign({path:'http://example.com/rest/',
|
|
parameters: 'foo=bar&gorp=banana',
|
|
signatures:{
|
|
api_key:'12345abcd',
|
|
shared_secret:'xyz-5309'
|
|
}});
|
|
document.getElementById('someLink').href=oauthObject.signed_url;
|
|
</code>
|
|
*
|
|
* that will sign as a "GET" using "SHA1-MAC" the url. If you need more than
|
|
* that, read on, McDuff.
