added check for additional token duration key (to make it work with Yahoo OAuth)

[ishaq]

Hello Bergeron,

I am using BDBOAuth1Manager with Yahoo Social APIs, noticed yahoo's token duration key is named different. So I added it.

I would suggest using the Objective-C SDK that Yahoo created instead of a bare-bones OAuth library such as this one, as it appears that their SDKs do a better job at handling tokens and user sessions without requiring a lot of work on the developer's part. Have a look at their documentation at http://developer.yahoo.com/social/sdk/objectivec/.

yes, I ended up using their ancient SDK. I wanted to use a modern library before but couldn't get their YQL API to work with BDBOAuth1Manager and their web-services are treated as 2nd class citizens.

btw, yahoo's own SDK's token renewal was broken which I fixed (in addition to the crash bug that everyone encounters when they first use it). I guess they started writing it but never finished it (or finished it and never tested it).

After working through Issue #19 and gaining some hands-on experience with Yahoo APIs, I wanted to see if I could get the YQL API working. It turns out to be quite simple - just instantiate an instance of BDBOAuth1Manager with your consumer key and secret and then perform your GET request. The YQL API doesn't require the oauth_token and thus the authorization handshake step is not required.

BDBOAuth1SessionManager *networkManager =
    [[BDBOAuth1SessionManager alloc] initWithBaseURL:[NSURL URLWithString:@"https://query.yahooapis.com/v1/public/"]
                                         consumerKey:@"key"
                                      consumerSecret:@"secret"];

// Add HTTP 400 to acceptable status codes to ensure we recieve API errors (missing parameters, wrong method, etc) as a success callback.
// We'll then need to check the root element in responseObject to see if the API returned an error.
NSMutableIndexSet *statusCodes = networkManager.responseSerializer.acceptableStatusCodes.mutableCopy;
[statusCodes addIndex:400];
networkManager.responseSerializer.acceptableStatusCodes = statusCodes;

[networkManager GET:@"yql"
         parameters:@{@"q": @"SELECT * FROM weather.forecast WHERE woeid = '2354842'", @"format": @"json"}
            success:^(NSURLSessionDataTask *task, id responseObject) {
                // Call succeeded, parse responseObject...
                NSLog(@"%@", responseObject);
            }
            failure:^(NSURLSessionDataTask *task, NSError *error) {
                // Call failed, handle error.
                NSLog(@"%@", error.localizedDescription);
            }];

If the request is successful, responseObject should be an instance of NSDictionary. A printout of it gives the following:
