Impossibile pubblicare su tumblr da iOS OAuth1.0, client OAConsumer

Question

Sto cercando di integrare "tumblr" nella mia applicazione. Sono in grado di ottenere correttamente il token di accesso. Ma, quando cerco di inviare, sto ottenendo il seguente errore

{"meta":{"status":401,"msg":"Not Authorized"},"response":[]} 

Sto usando il cliente OAuthConsumer per iOS, che ho tirato, se da MGTwitterEngine.

Questo è quello che ho provato.

#import "ViewController.h" 


#define consumer_key @"u9iZvT8KIlrTtUrh3vUeXXXXXXXXXXXXXAfgpThGyom8Y6MKKCnU" 
#define consumer_secret @"xfA10mQKmALlpsnrFXXXXXXXXXXXXXXXXXXXXXXXXXX" 
#define request_token_url @"http://www.tumblr.com/oauth/request_token" 
#define access_token_url @"http://www.tumblr.com/oauth/access_token" 
#define authorize_url @"http://www.tumblr.com/oauth/authorize?oauth_token=%@" 
#define base_url @"http://api.tumblr.com/v2/user/XXXXXXXXXXXXX.tumblr.com/info"

Qual è l'errore che sto facendo qui? Perché sto ricevendo quell'errore? Ho seguito correttamente i passaggi?

Answer 1

Si prega di XXX out your consumer_key e consumer_secret per evitare l'uso indesiderato di loro. Codice saggio ci sono alcune cose che potresti voler cercare qui.

1. siete in grado di utilizzare un OAuth 'get' richiesta come "http://api.tumblr.com/v2/user/info"? Se è possibile ricevere una richiesta "GET", il token di accesso è valido e si può vedere come si inviano i parametri del post.

2. Assicurarsi di passare i parametri come corpo HTTP e i parametri della firma. Il corretto ordinamento dei parametri è probabilmente fornito dalla libreria.

   NSString * postbody = @ "corpo = myBodyText & type = text";

   [oRichiesta setHTTPBody: [postbody dataUsingEncoding: NSUTF8StringEncoding allowLossyConversion: TRUE]];
