android - 授权成功后如何获取AccessToken发布推特

Question

这一直很痛苦。我不知道我对 AccessToken 做错了什么，但我尝试在调用 Twitter4j 的 updateStatus 发布到 Twitter 之前设置它。

我尝试了不同的方法来获取 AccessToken，我只使用 Twitter4J。

AccessToken accessToken = twitter.getOAuthAccessToken(twitter.getOAuthRequestToken(), verifier);

给出错误:

05-09 12:06:45.776: D/GameName(678): Received authentication challenge is null

我可以切换到 Twitter 浏览器进行授权。我输入我的用户名和密码，按“授权应用程序”。然后浏览器更改为“重定向”回我的应用程序。我的应用程序出现并繁荣!它崩溃了!我的应用调用了 onNewIntent。

授权代码效果很好: (twitter是成员变量)

    public void twitterAuthorize() 
    {   
        try 
        {
            twitter = new TwitterFactory().getInstance();
            twitter.setOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);

            RequestToken requestToken = twitter.getOAuthRequestToken(Constants.OAUTH_CALLBACK_URL);                         
            startActivityForResult(new Intent(Intent.ACTION_VIEW, Uri.parse(requestToken.getAuthorizationURL())), TWITTER_AUTHORIZE_ACTIVITY_RESULT_CODE); 
        } 
        catch (TwitterException e) 
        { 
                Log.d(Globals.sApplicationName, e.getMessage());
                e.printStackTrace();                 
        }       

    }

从授权返回，我到达“AccessToken accessToken =...”行，抛出异常。

@Override
protected void onNewIntent(Intent intent) 
{
    super.onNewIntent(intent);

    Log.d(Globals.sApplicationName, "ENTERED: onNewIntent");

    Uri uri = intent.getData();
    if (uri != null && uri.toString().startsWith(Constants.OAUTH_CALLBACK_URL)) 
    {
        Log.d(Globals.sApplicationName, "oAuth: " + uri.toString());
        String verifier = uri.getQueryParameter("oauth_verifier");

        try {
            if (verifier != null)
            {
                Log.d(Globals.sApplicationName, "Verifier: " + verifier);


                //Try 1: doesn't work
                //AccessToken a = new AccessToken(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);

                //Try 2: doesn't work               
                AccessToken accessToken = twitter.getOAuthAccessToken(twitter.getOAuthRequestToken(), verifier);

                //Try 3: doesn't work
                //String token = uri.getQueryParameter("oauth_token");      
                //AccessToken accessToken = new AccessToken(token, verifier);

                //twitter = new TwitterFactory().getInstance();

                twitter.setOAuthConsumer(Constants.CONSUMER_KEY, Constants.CONSUMER_SECRET);
                twitter.setOAuthAccessToken(accessToken);

                // create a tweet
                Date d = new Date(System.currentTimeMillis());
                String tweet = "#OAuth working! " + d.toLocaleString();

                // send the tweet
                twitter.updateStatus(tweet);
            }
        } catch (Exception e) {

            Log.d(Globals.sApplicationName, e.getMessage());
            e.printStackTrace();
        }
    }
}

我在调用堆栈上遇到了这些错误(我刚刚替换了，所以我在这篇论坛帖子中将其保密):

请指教，这真是令人费解。我查看了其他帖子，他们提到了有关时间戳的内容，但这对我来说没有意义。

谢谢

Answer 1

我认为您正在生成一个与您拥有的验证程序无关的新请求 token 。

尝试保存 twitter 对象和您第一次请求的 token 并尝试执行如下操作:

1. 列表项
2. 使用 consumerkey 和 consumerkeysecret 从 twitter factory 获取 twitter 对象
3. 获取请求 token (twitter.getrequesttoken())
4. 向 requesttoken 请求授权 url
5. 保存 twitter 对象和请求 token
6. 转到 Twitter 并验证
7. 通过回调返回并检索验证者
8. 获取保存的 twitterobject 和 requesttoken
9. 那些保存的 twitterobject 和 requesttoken 应该与验证器一起使用来验证用户....

那么你就通过了身份验证
