Ich habe die folgende Implementierung von atwitter Client mitrauth (OAuth1), basierend auftwitter-timeline-cli.py Drehbuch in derrauth Beispiele:

from rauth.service import OAuth1Service

class TwitterClient:

    KNOWN_USERS = {
        'user1' : ("xxx", "yyy", "2342354"), # These should be real tokens
    }

    def __init__(self):
        # Get a real consumer key & secret from https://dev.twitter.com/apps/new
        self.twitter = OAuth1Service(
            name='twitter',
            consumer_key=TWITTER_CONSUMER_KEY,
            consumer_secret=TWITTER_CONSUMER_SECRET,
            request_token_url='https://api.twitter.com/oauth/request_token',
            access_token_url='https://api.twitter.com/oauth/access_token',
            authorize_url='https://api.twitter.com/oauth/authorize',
            base_url='https://api.twitter.com/1/')

    def authorize(self):
        request_token, request_token_secret = self.twitter.get_request_token()
        authorize_url = self.twitter.get_authorize_url(request_token)
        print 'Visit this URL in your browser: ' + authorize_url
        pin = raw_input('Enter PIN from browser: ')
        return request_token, request_token_secret, pin

    def init_session(self, user):
        if user in self.KNOWN_USERS :
            request_token, request_token_secret, pin = self.KNOWN_USERS[user]
        else:
            request_token, request_token_secret, pin = self.authorize()
        session = self.twitter.get_auth_session(request_token,
                                                request_token_secret,
                                                method='POST',
                                                data={'oauth_verifier': pin})
        return session

    def list_tweets(self, user):
        session = self.init_session(user)
        params = {'include_rts': 1,  # Include retweets
                  'count': 10}       # 10 tweets

        r = session.get('statuses/home_timeline.json', params=params)

        for i, tweet in enumerate(r.json(), 1):
            handle = tweet['user']['screen_name'].encode('utf-8')
            text = tweet['text'].encode('utf-8')
            print '{0}. @{1} - {2}'.format(i, handle, text)

tc = TwitterClient()

tc.list_tweets('user1')

Die Idee ist, dass, wenn der Benutzer nicht bekannt ist, er aufgefordert wird, die Anwendung zu autorisieren. Wenn der Benutzer diese Anwendung hingegen bereits autorisiert hat, sollten die Autorisierungstoken (request_token, request_token_secret, pin) erneut verwendet werden (normalerweise befinden sich die Token in einer Datenbank; sie sind vorerst in der Datenbank fest codiert Skript)

Das funktioniert aber nicht:

Traceback (most recent call last):

    tc.list_tweets('user1')
  File "my-twitter-timeline-cli.py", line 43, in list_tweets

    raise KeyError(PROCESS_TOKEN_ERROR.format(key=bad_key, raw=r.content))

Ist es möglich, wiederzuverwendenOAuth1 Autorisierungs-Token?
