android - OAuth、Twitter 和 Android : fails in http-communication with the server 问题

Question

有没有人有一个使用 Android 的 Twitter 的 OAuth 身份验证的工作示例？我尝试同时使用 Twitter4J 和 SignPost，但出现非常奇怪的错误，提示 twitter.com 是未知主机。我了解到 SignPost 库和 Android 存在问题 ( under Google Android )，根据项目的主页，CommonsHttpOAuth* 类应该可以工作。

这是我的路标:

private void getReqTokenAndAuthenticateUsingSignPost() {
    String callbackUrl = "twitter-test:///";
    CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
            CONSUMER_SECRET);
    CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
            "http://twitter.com/oauth/request_token", "http://twitter.com/oauth/access_token",
            "http://twitter.com/oauth/authorize");

    String tokenStr = consumer.getToken();
    String tokenSecretStr = consumer.getTokenSecret();

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
    Editor edit = preferences.edit();
    edit.putString(REQ_TOKEN, tokenStr);
    edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);

    try {
        String authUrl = provider.retrieveRequestToken(consumer, callbackUrl);
        Uri authenticationUri = Uri.parse(authUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
    } catch (OAuthMessageSignerException e) {
        e.printStackTrace();
    } catch (OAuthNotAuthorizedException e) {
        e.printStackTrace();
    } catch (OAuthExpectationFailedException e) {
        e.printStackTrace();
    } catch (OAuthCommunicationException e) {
        e.printStackTrace();
    }

}

这是我的 Twitter4J 代码:

private void getReqTokenAndAuthenticateUsingTwitter4J() {

    String callbackUrl = "twitter-test:///";
    try {
        // Prepare a request token, based on consumer key and consumer
        // secret
        ConfigurationBuilder builder = new ConfigurationBuilder();
        builder.setOAuthConsumerKey(CONSUMER_KEY);
        builder.setOAuthConsumerSecret(CONSUMER_SECRET);
        Configuration cfg = builder.build();
        Twitter t = new TwitterFactory(cfg).getInstance();

        RequestToken requestToken = t.getOAuthRequestToken(callbackUrl);
        String tokenStr = requestToken.getToken();
        String tokenSecretStr = requestToken.getTokenSecret();

        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
        Editor edit = preferences.edit();
        edit.putString(REQ_TOKEN, tokenStr);
        edit.putString(REQ_TOKEN_SECRET, tokenSecretStr);
        if (edit.commit()) {
            // Launch the browser for authentication in twitter's web-gui
            Uri authenticationUri = Uri.parse(requestToken.getAuthenticationURL());
            startActivity(new Intent(Intent.ACTION_VIEW, authenticationUri));
        }
    } catch (TwitterException e) {
        e.printStackTrace();
    }
}

是的，我有一个具有 Internet 权限的 list 和一个回调 url 的 Intent 过滤器。这是运行 SignPost 代码时 logcat 的输出:

有人解决了吗？我被困在这里了。我可以让代码作为 Java SE 程序运行，但它在 android 上失败...

检查并确认两件事 -

1-在您在 Twitter 网站上创建的 Twitter 应用中提供回调 URL(转到您的应用-> 设置->回调 URL) Click here

2-转到手机设置，然后单击“日期和时间”并选择“自动”(请确保您的设备时区和时间、日期均正确)如果您的时间、日期和时区不正确，那么你不能发推文。
