ASI-OAuth

This is implementation of OAuth 1.0 signing + authorization flow, built on top of ASI-HTTP-Request.

This set of classes depends on:

• https://github.com/keybuk/asi-http-request-oauth
• https://github.com/pokeb/asi-http-request

Basic usage:

ASIOAuthClient* oauthClient = [[ASIOAuthClient alloc] init];

// setup API keys
oauthClient.consumer.consumerKey = YOUR_CONSUMER_KEY;
oauthClient.consumer.consumerSecret = YOUR_CONSUMER_SECRET;

// configure your oauth provider routes
oauthClient.consumer.oauthRequestTokenURL = @"https://api.dropbox.com/1/oauth/request_token";
oauthClient.consumer.oauthAuthorizeURL = @"https://www.dropbox.com/1/oauth/authorize";
oauthClient.consumer.oauthAccessTokenURL = @"https://api.dropbox.com/1/oauth/access_token";

// used to detect whether user pressed "cancel" while authorization
oauthClient.consumer.oauthCancelURL = @"https://www.dropbox.com/home";

// set your delegate, see ASIOAuthClientDelegate.h for details
oauthClient.delegate = yourDelegate;

// this starts authorization, e.g. pops up WebView overlay
[oauthClient authorize];

Any extra data (like user id) returned by OAuth provider saves to oauthClient.consumer.userData on successful authorization.

Request signing:

[oauthClient.consumer signRequest:yourASIHTTPRequest];

It's possible to override WebView-based helper with your own implementation. Your class must conform to ASIOAuthWebHelperProtocol and use ASIOAuthWebHelperDelegate to return redirect requests to ASIOAuthConsumer, use the following code to replace default helper:

oauthClient.consumer.authorizeHelper = yourHelper;
