Read Tweets from a User's Timeline Using v2 API

This example shows you how to read Tweets from a user's timeline using Data Pipeline's TwitterTimelineTweetsReader. TwitterTimelineTweetsReader uses Twitter v2 API to obtain records from Twitter.

In this demo code you are going to use OAuth 2.0 Bearer Token as an authentication standard. Bearer Token allows you to make API requests on behalf of your Twitter developer App. If you are making an API call on behalf of a Twitter user, you can use OAuth 1.0a as an authentication standard by specifying Access Token and Secret.

    private static final String BEARER_TOKEN = "YOUR_BEARER_TOKEN";

    public static void main(String[] args) {

        TwitterTimelineTweetsReader reader = new TwitterTimelineTweetsReader(API_KEY, API_SECRET, BEARER_TOKEN, "TwitterDev");
        reader.setMaxResults(100);

        Job.run(reader, new StreamWriter(System.out));
    }
}

Code Walkthrough

1. First, parameters which are going to be used to connect to Twitter v2 API are specified.
2. TwitterTimelineTweetsReader is created to read Tweets published by a Twitter account with a username TwitterDev.
3. reader.setMaxResults(100) sets the maximum number of records that will be obtained by the endpoint to 100.
4. Data are transferred from TwitterTimelineTweetsReader to the console via Job.run() method. See how to compile and run data pipeline jobs.

TwitterTimelineTweetsReader
