Displaying user timeline of the authenticating user
In this section, you will learn how to display user timeline of the authenticating user.
The timeline is the term used to describe a collected stream of Tweets listed in real-time order. The user timeline is the most recent statuses posted from a user.
For user timeline we need OAuth authorization scheme of Twitter for authenticating user.
Twitter4j Java library have this OAuth support.
Please follow the below steps to get Twitter OAuth support :
STEP-1 : For this you need to register your application at http://twitter.com/oauth_clients/new . Please set the Default Access type to Read, Write, & Direct Messages . This will provide access to read & write tweet/status and also provide facility to send direct messages.
STEP-2 :After registering your application you will get the following things :
- Consumer key
XXXXXXXXXXXX
- Consumer secret
XXXXXXXXXXXX
- Request token URL XXXXXXXXXXXX
- Authorize URL
XXXXXXXXXXXX
- Access token URL XXXXXXXXXXXX
- Callback URL XXXXXXXXXXXX
- Access token XXXXXXXXXXXX
- Access token secret XXXXXXXXXXXX
- Access level Read XXXXXXXXXXXX
NOTE : Please note down the keys before closing page after application registration and also don't share these keys with anyone.
CODE
Place the keys which you got after registration by replacing the square [] brackets .Code is given below :
