A better version of this library is available by the name of Fetchwitter
If you happen to follow my updates at Twitter, you may have come across ranting me about bugs in Twitter API v1.1 documentations.
Twitter made an oAuth authorization compulsory for any type of request made to its API with release of their latest version 1.1. It is obvious that publicly accessible data was gated behind a complicated authorization mechanism and therefore was not welcomed by majority of developers.
After going through few months’ procrastination, I finally figured out that I will have to work it out sooner or later. So I went through few of these discussions at Twitter devs and stackoverflow forums but in vain and later decided to go through official documentations that turned out to be fruitful at the end.
Twitter API has two types of authentication models, first is user type authentication and other is application-only authentication. In case of a user authentication, user has to authorise the application in order to provide it the access to various request methods while in case of an application-only authentication, application makes the requests at user’s behalf and of course there are limitations of certain extents to such liberty.
The process revolves around getting an
access token by exchanging the credentials with which we can make requests to Twitter API 1.1 endpoint. Following outline explains the process flow.
First of you will need to register/login at https://dev.twitter.com/apps and create a new application. Fill out the required fields and it will generate the required credentials for you. The only credentials you need are “consumer key” and “consumer secret”.
Now you need to make a POST request to API’s oAuth endpoint to exchange above-mentioned credentials for an
access token. The request made at this stage requires Authorization headers. This will result in a response with app level bearer
access token. You might want to save/cache the acquired
access token instead of making a request each time.
Now that you have the
access token, you can make requests to Twitter API endpoint and receive data in response. The request made at this stage also requires inclusion of Authorization headers.
Now since all these results are returned in plain text and so are the links, hashtags and mentions in the tweets. This issue can easily be solved by using regex match and replace methods, that is available in this example as
text2tweet() function. You can get the complete source at Github.
