android - 如何从推特获取主页时间线数据

Question

我开发了一个应用程序。在我的应用程序中，我想获取推特主页时间线数据并显示 ListView 。我使用了 twitter4j 库。我进行了很多搜索，还阅读了推特文档。在通过以下方式获取用户时间线数据的文档中使用波纹管网络服务:“https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=twitterapi&count=2”。它工作正常，将显示数据。但我的要求是获取主页时间线数据。在该文档中，他们提供了以下网络服务:https://api.twitter.com/1.1/statuses/home_timeline.json.This不工作，家庭时间线数据不会显示。请有人建议我，如何做到这一点。提前致谢

Answer 1

使用此代码。这是我的一个应用程序的生产代码。我为 Strings 获取 2 个值<强> TWITTER_CONSUMER_KEY 和 TWITTER_CONSUMER_SECRET 来 self 的 strings.xml文件。 Strings 的值<强> twit_access_token 和 twit_access_token_secret 是从我的 SharedPreferences 拉进来的文件。用您自己的存储方法替换这些位。

try {
    ConfigurationBuilder builder = new ConfigurationBuilder();

    // GET THE CONSUMER KEY AND SECRET KEY FROM THE STRINGS XML
    String TWITTER_CONSUMER_KEY = getActivity().getString(R.string.TWITTER_CONSUMER_KEY);
    String TWITTER_CONSUMER_SECRET = getActivity().getString(R.string.TWITTER_CONSUMER_SECRET);

    // TWITTER ACCESS TOKEN
    String twit_access_token = twitPrefs.getString(PREF_KEY_OAUTH_TOKEN, null);

    // TWITTER ACCESS TOKEN SECRET
    String twit_access_token_secret = twitPrefs.getString(PREF_KEY_OAUTH_SECRET, null);

    builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
    builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);
    builder.setOAuthAccessToken(twit_access_token);
    builder.setOAuthAccessTokenSecret(twit_access_token_secret);
    builder.setJSONStoreEnabled(true);
    builder.setIncludeEntitiesEnabled(true);
    builder.setIncludeMyRetweetEnabled(true);
    builder.setIncludeRTsEnabled(true);

    AccessToken accessToken = new AccessToken(twit_access_token, twit_access_token_secret);
    Twitter twitter = new TwitterFactory(builder.build()).getInstance(accessToken);

    Paging paging = new Paging(200); // MAX 200 IN ONE CALL. SET YOUR OWN NUMBER <= 200
    statuses = twitter.getHomeTimeline(paging);

    try {
        String strInitialDataSet = DataObjectFactory.getRawJSON(statuses);
        JSONArray JATweets = new JSONArray(strInitialDataSet);

        for (int i = 0; i < JATweets.length(); i++) {
                JSONObject JOTweets = JATweets.getJSONObject(i);
                Log.e("TWEETS", JOTweets.toString());
        }

    } catch (Exception e) {
        // TODO: handle exception
    }
} catch (Exception e) {
    // TODO: handle exception
}

注意 1: statuses是 List<Status> statuses = new ArrayList<Status>(); 的实例我已将其声明并实例化为全局实例。

注意2:这个属性是必须的builder.setJSONStoreEnabled(true);如果您希望结果在 JSON 中格式。如果你需要它没有 JSON , 让我知道。

最终更新:

在测试 OP 的整个代码并在测试应用程序中调试几乎所有之后，罪魁祸首原来是一行(好吧，实际上是 2 行):

Paging paging = new Paging(200); // MAX 200 IN ONE CALL. SET YOUR OWN NUMBER <= 200
statuses = twitter.getHomeTimeline(paging);

事实证明，出于某种原因，Twitter API 不喜欢 Paging paging = new Paging(200); .将其更改为 Paging paging = new Paging(10);奇怪的是，给了我 20 条推文。删除 Paging....行完全，给了我19。真的很奇怪的结果。但我目前最好的猜测是该应用程序可能是 Twitter 开发者网络上的新应用程序(它在身份验证期间仍然显示该应用程序无法访问直接消息)。

将该部分更改为:

// Paging paging = new Paging(10);
statuses = twitter.getHomeTimeline();
