Android上的路标OAuth：如何在两次成功运行之间重新创建消费者？

provider.retrieveAccessToken(consumer,oauth_verifier);

final Editor edit = prefs.edit();
edit.putString(OAuth.oAUTH_TOKEN,consumer.getToken());
edit.putString(OAuth.oAUTH_TOKEN_SECRET,consumer.getTokenSecret());
edit.commit();

之后,您可以像这样重新创建消费者：

private OAuthConsumer getConsumer(SharedPreferences prefs) {
    String token = prefs.getString(OAuth.oAUTH_TOKEN,"");
    String secret = prefs.getString(OAuth.oAUTH_TOKEN_SECRET,"");
    OAuthConsumer consumer = new CommonshttpOAuthConsumer(Constants.CONSUMER_KEY,Constants.CONSUMER_SECRET);
    consumer.setTokenWithSecret(token,secret);
    return consumer;
}

获得消费者后,您可以进行API调用,消费者将对其进行签名.

DefaulthttpClient httpclient = new DefaulthttpClient();
httpGet request = new httpGet(url);
consumer.sign(request);
httpResponse response = httpclient.execute(request);

根据@L_616_5@：

路标对象非常轻量级,因此建议您为应用程序中必须发送已签名http请求的每个线程创建OAuthConsumer和Oauthprovider.这两个对象也是可序列化的,因此您可以在以后保留并恢复它们.
