android – twitter4j 401身份验证错误持久存取AccessToken
作者：互联网
我正在努力弄清楚发生了什么.我有一个典型的应用程序结构,它产生一个负责获取Twitter令牌的OAuthActivity,然后我的主应用程序活动将该令牌用于各种与twitter相关的操作.
我的OAuthActivity有效.我得到一个身份验证令牌,Twitter网页正确显示我的应用程序名称等….此外,在该活动中,我可以发送推文并发布. .这意味着OAuthActivity工作,时钟同步,令牌有效等等……
但是当这个OAuthActivity完成并返回到调用活动时,每当我尝试使用该标记(从持久化的密钥/秘密重新创建它)时,无论什么操作,操作总是会失败,并抱怨说AuthChallenge报告为null.就像我提供了一个空令牌,但我还没有！
请查看附件我的OAuthActivity的来源,以及我如何在主要活动中初始化Twitter对象的来源.如果你看错了,请告诉我.
PD – 我显然已经检查过我分配的令牌值与我得到的相同！还尝试了不同的方式来实例化Twitter,通过属性,通过构建器,通过集….并没有任何变化:(
编辑 – >我发现我必须在新的Twitter对象上调用“verifyCredentials()”,如果我想重用一个令牌,但是……没有运气！ (请在最后找到发布的例外)
EDIT-2 – ;如果我同时使用子活动和父项
mTwitter=TwitterFactory.getSingleton()
然后twitter对象起作用,但这对我来说并不是真的可以接受,因为它不使用持久性,我需要每次都授权应用程序.此外,只有Twitter对象被授权,TwitterStream不断抛出异常.
干杯!
父活动的源代码,我尝试使用在子活动中获得的访问令牌,如下所示.无论我尝试使用此令牌,总是获得401.
private void init_twitter(String tok, String sec) {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(Conf.OAUTH_CONSUMER_KEY)
.setOAuthConsumerSecret(Conf.OAUTH_CONSUMER_SECRET)
.setOAuthAccessToken(tok)
.setOAuthAccessTokenSecret(sec);
TwitterFactory tf = new TwitterFactory(cb.build());
mTwitter=tf.getInstance();
/** This always fails, even though I call this routine with the
correct token & secret !!! See at the enf of message for an alternate
routine like this one that makes use of verifyCredentials and
also fails. */
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try {
mTwitter.updateStatus("yello 2");
} catch (TwitterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}}).start();
}
孩子OAuthActivity的SOurce Code,显然是因为我获得了访问令牌&我能发推文：
import a lot;
public class TwitterLogin extends Activity {
private final String TAG = "TwitterLogin";
public final static String PREF_KEY_OAUTH_TOKEN="twitter.oauth.token", PREF_KEY_OAUTH_SECRET="twitter.oauth.secret", PREF_KEY_TWITTER_LOGIN="twitter.oauth.login";
private SharedPreferences mPreferences;
private Twitter twitter = new TwitterFactory().getInstance();
@Override
public void onCreate(Bundle savedInstanceState) {
Log.i(TAG, "Starting task to retrieve request token.");
this.mPreferences = PreferenceManager.getDefaultSharedPreferences(this);
super.onCreate(savedInstanceState);
getActionBar().setTitle("TWITTER AUTHENTICATION");
}
private void returnParent(boolean result) {
setResult(result?Activity.RESULT_OK:Activity.RESULT_CANCELED, null);
if (Conf.LOG_ON) Log.d(TAG, "TWITTER AUTH: END PROCESS , GLOBAL RESULT "+result);
/** THE FOLLOWING THING WORKS !!!!! IT SUCCESSFULLY TWEETS */
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try {
twitter.updateStatus("yello");
} catch (TwitterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}}).start();
finish();

使用我确定正确的令牌调用VerifyCredentials时遇到的异常：

这是为了使用verifyCredentials而修改的函数：
private void init_twitter_2(final String tok, final String sec) throws TwitterException {
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
.setOAuthConsumerKey(Conf.OAUTH_CONSUMER_KEY)
.setOAuthConsumerSecret(Conf.OAUTH_CONSUMER_SECRET);
// .setOAuthAccessToken(tok)
// .setOAuthAccessTokenSecret(sec);
TwitterFactory tf = new TwitterFactory(cb.build());
mTwitter=tf.getInstance();
Log.d(TAG, "init_twitter_2 "+tok+","+sec);
new Thread(new Runnable(){
@Override
public void run() {
// TODO Auto-generated method stub
User u;
try {
/** also tried setting token&secret like this, instead of in the builder-->no success */
mTwitter.setOAuthAccessToken(new AccessToken(tok,sec));
u = mTwitter.verifyCredentials();
Log.d(TAG, "User: "+u.getName());
} catch (TwitterException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}}).start();
}
解决方法:
有愚蠢的人,愚蠢的人,愚蠢的人,然后就是我.一个星期以来,我一直在努力寻找代码,追踪Twitter4j,用curl复制oauths,怀疑垃圾收集活动,追踪DDMS,计算令牌上的哈希……只是发现我有2个Conf.OAUTH_CONSUMER_xxxxx实例不同的价值观
由于这些东西来自常数,名字相似,我没有意识到.
感叹 – 50个声望指向厕所！
