在应用程序后台发送推文

Question

我已经在互联网上搜索过了。为了发送推文，我找到了许多解决方案，并且使用意图得到了更好的解决方案。

String tweetUrl = "https://twitter.com/intent/tweet?text=PUT TEXT HERE &url="+ "https://www.google.com";
Uri uri = Uri.parse(tweetUrl);
startActivity(new Intent(Intent.ACTION_VIEW, uri));

但我只想在后台发送推文。如果有人这样做过，请与我分享。我的要求是在帖子发布到我的基于社交网络的应用程序时在后台发送推文。我可以在 facebook 的情况下做到这一点，但仍然在 Twitter 上苦苦挣扎。

下面是我为 Twitter 应用程序进行身份验证的代码：-

class twAsyn extends AsyncTask<String, Void, String>{
    @Override
    protected String doInBackground(String... params) {
        // TODO Auto-generated method stub
         askOAuth();
        return null;  
    }

}

private void checkForSavedLogin() {  
     // Get Access Token and persist it  
     new accessUser().execute();
}  

class accessUser extends AsyncTask<String, Void, String>{

    @Override
    protected String doInBackground(String... params) {
        // TODO Auto-generated method stub
         AccessToken a = getAccessToken();  

            // storeAccessToken(a);
             loggedIUser.setTwSharing(true);
             if (a!=null) {

             // initialize Twitter4J  
             twitter = new TwitterFactory().getInstance();  
             twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);  
             twitter.setOAuthAccessToken(a);  
             ((TwitterApplication)getApplication()).setTwitter(twitter);  
             final User user;
             finish(); 
              }
        return null;
    }

}

private AccessToken getAccessToken() {
    SharedPreferences settings = getSharedPreferences(Constants.PREFS_NAME, MODE_PRIVATE);
    String token = settings.getString("accessTokenToken", "");
    String tokenSecret = settings.getString("accessTokenSecret", "");
    if (token!=null && tokenSecret!=null && !"".equals(tokenSecret) && !"".equals(token)){
        return new AccessToken(token, tokenSecret);
    }
    return null;
}

private void getConsumerProvider() {
    OAuthProvider p = ((TwitterApplication)getApplication()).getProvider();
    if (p!=null){
        provider = p;
    }
    CommonsHttpOAuthConsumer c = ((TwitterApplication)getApplication()).getConsumer();
    if (c!=null){
        consumer = c;
    }
}



private void setConsumerProvider() {
    if (provider!=null){
        ((TwitterApplication)getApplication()).setProvider(provider);
    }
    if (consumer!=null){
        ((TwitterApplication)getApplication()).setConsumer(consumer);
    }
}


private void storeAccessToken(AccessToken a) {
    SharedPreferences settings = getSharedPreferences(Constants.PREFS_NAME, MODE_PRIVATE);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("accessTokenToken", a.getToken());
    editor.putString("accessTokenSecret", a.getTokenSecret());
    editor.commit();
}

@Override
protected void onResume() {
    super.onResume();
    System.out.println("RESUMING!!");
    if (this.getIntent()!=null && this.getIntent().getData()!=null){
        Uri uri = this.getIntent().getData();
        new twUserAcces(uri).execute();
    }
}

class twUserAcces extends AsyncTask<String, Void, String>{
    Uri uri;
    String verifier;
    public twUserAcces(Uri uri) {
        // TODO Auto-generated constructor stub
        this.uri = uri;
        if (uri != null && uri.toString().startsWith(CALLBACK_URL)) {
            verifier = uri.getQueryParameter(oauth.signpost.OAuth.OAUTH_VERIFIER);

        }
    }

    @Override
    protected void onPostExecute(String result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        checkForSavedLogin();
    }

    @Override
    protected String doInBackground(String... params) {
        // TODO Auto-generated method stub
        try {


            // this will populate token and token_secret in consumer
            provider.retrieveAccessToken(consumer, verifier);

            // Get Access Token and persist it

            System.out.println(">>>>>>>> accesstoker "+consumer.getToken());
            System.out.println(">>>>>>>> accesstoker "+consumer.getTokenSecret());
            AccessToken a = new AccessToken(consumer.getToken(), consumer.getTokenSecret());
            storeAccessToken(a);

            // initialize Twitter4J
            twitter = new TwitterFactory().getInstance();
            twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
            twitter.setOAuthAccessToken(a);
            ((TwitterApplication)getApplication()).setTwitter(twitter);
            Log.e("Login>>>>>>>>>>>>>>>>>>>>>.", "Twitter Initialised");


            User user = null;
            long h=twitter.getId();
            user = (User)twitter.getUserLists(0);

            finish();
        } catch (Exception e) {
            //Log.e(APP, e.getMessage());
            e.printStackTrace();
            System.out.println("e.getMessage()=="+e.getMessage());
            //Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
        }

        return null;
    }

}

private void askOAuth() {
    try {


        consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
        provider = new CommonsHttpOAuthProvider("https://twitter.com/oauth/request_token", "https://twitter.com/oauth/access_token", "https://twitter.com/oauth/authorize");
        String authUrl = provider.retrieveRequestToken(consumer, CALLBACK_URL);
        //Toast.makeText(this, "Please authorize this app!", Toast.LENGTH_LONG).show();
        setConsumerProvider();
        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
    } catch (Exception e) {
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
    }
}

在java中发送推文，你可以使用Twitter4J

创建一个 Twitter 应用程序：参考here

初始化您的对象：使用 twitter 应用凭据填写凭据

ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true)
  .setOAuthConsumerKey("")
  .setOAuthConsumerSecret("")
  .setOAuthAccessToken("")
  .setOAuthAccessTokenSecret("");
TwitterFactory tf = new TwitterFactory(cb.build());

发送您的推文

Twitter twitter = TwitterFactory.getSingleton();
Status status = twitter.updateStatus(latestStatus);

最佳实践请参考here
