Twitter Oauth

Oauth_logo.svg.png

What is Oauth?

It’s an open protocol which allows to secure an authorization in a simple and standard method from web, mobile and desktop applications.Facebook, Google Twitter, Github and more web services use this protocol to authenticate user. Using Oauth is very convenient, because it delegates user authentication to the service which host user account. It allows us to get resources from another web service without giving any login or password. If you have a service and want to prepare a authentication via Twitter, the best solution is to use OAuth. Recently Open Event team met a problem in an user profile page. We’d like to automatically fill information about user. Of course, to solve it we use Oauth protocol, to authenticate with Twitter After a three-steps authentication we can get name and profile picture.If you need another information from Twitter profile like recent tweets or followers’ list. You have to visit Twitter API site to see more samples of resource which you can get

How do Open event team implement communication between Orga-server and Twitter?

All services have a very similar flow. Below i will show you how it looks in our case.

Before starting you need to create your own twitter app. You can create app in Twitter apps site https://apps.twitter.com/. If  create an app you will see a CONSUMER KEY and CONSUMER SECRET KEY which shouldn’t be human-readable, so remember not to share these keys.

Below example shows how to get basic information about twitter profile

We use oauth2 python library https://github.com/joestump/python-oauth2

consumer = oauth2.Consumer(key=TwitterOAuth.get_client_id(),

                          secret=TwitterOAuth.get_client_secret())

client = oauth2.Client(consumer)

TwitterOAuth.get_client_id() CONSUMER KEY

TwitterOAuth.get_client_secret()  – CONSUMER SECRET KEY

Then we send GET request to request_token endpoint to get oauth_token

client.request('https://api.twitter.com/oauth/request_token', "GET")
Response: oauth_token=Z6eEdO8MOmk394WozF5oKyuAv855l4Mlqo7hhlSLik&
oauth_token_secret=Kd75W4OQfb2oJTV0vzGzeXftVAwgMnEK9MumzYcM&
oauth_callback_confirmed=true

Next step is to redirect user to Twitter Authentication site

twitter-oauth.png

You can see in an url a redirect_uri. So after sign in Client will get a callback from Twitter with oauth_verifier and oauth_token params

https://api.twitter.com/oauth/authenticate?oauth_token=RcYGqAAAAAAAwdbbAAABVoM1UMo&oauth_token_secret=wZfpPpCugAmdF3AuohEnvBTRxdCmllxu&oauth_callback_confirmed=true&redirect_uri=http://open-event-dev.herokuapp.com/tCallback

The last step is to get an access token. If we have an oauth_verifier and an oauth_token it’s pretty easy

def get_access_token(self, oauth_verifier, oauth_token):

   consumer = self.get_consumer()

   client = oauth2.Client(consumer)

   return client.request(

       self.TW_ACCESS_TOKEN_URI + 'oauth_verifier=' + oauth_verifier + 
       "&oauth_token=" + oauth_token, "POST")

Where TW_ACCESS_TOKEN_URI is https://api.twitter.com/oauth/access_token

Final step is to get our user information

resp, content = client.request("https://api.twitter.com/1.1/users/show.json?
                               screen_name=" + access_token["screen_name"] +
                               "&user_id=" + access_token["user_id"] , "GET")

user_info = json.loads(content)

In an user_info variable you can get a profile picture or a profile name.

Summarizing, oauth protocol is very secure and easy to use by developer. At the beginning an oauth flow can seem to be a little hard to  understand but if you spend some time trying tp understand it, everything becomes easier.  And it’s secured. because you don’t need to store a login or a password, and an access token has an expired time. This is the main feature of Oauth protocol.

Unit Testing

There are many stories about unit testing. Developers sometimes say that they don’t write tests because they write a good quality code. Does it make sense, if no one is infallible?.

At studies only a  few teachers talk about unit testing, but they only show basic examples of unit testing. They require to write a few tests to finish final project, but nobody really  teaches us the importance of unit testing.

I have also always wondered what benefits can it bring. As time is a really important factor in our work it often happens that we simply resign of this part of process development to get “more time” rather than spend time on writing stupid tests. But now I know that it is a vicious circle.

Customers requierments does not help us. They put a high pressure to see visible results not a few statistics about coverage status. None of them cares about some strange numbers. So, as I mentioned above, we usually focuses on building new features and get riid of tests. It may seem to save time, but it doesn’t.

In reality tests save us a lot of time because we can identify and fix bugs very quickly. If a bug ocurrs because someone’s change we don’t have to spend long hours trying to figure out wgat is going out. That’s why we need tests.  

It is especially visible in huge open source projects. FOSSASIA organization has about 200 contributors. In OpenEvent project we have about 20 active developers, who generate many lines of code every single day. Many of them change over and over again as well as interfere  with each other.

Let me provide you with a simple example. In our team we have about 7 pull requests per day. As I mentioned above we want to make our code high quality and free of bugs, but without testing identifying if pull request causes a bug is very difficult task. But fortunately this boring job makes Travis CI for us. It is a great tool which uses our tests and runs them on every PR  to check if bugs occur. It helps us to quickly notice bugs and maintain our project very well.

What is unit testing?

Unit testing is a software development method in which the smallest testable parts of an application are tested

Why do we need writing unit tests?

Let me point all arguments why unit testing is really important while developing a project.

  • To prove that our code works properly

If developer adds another condition, test checks if method returns correct results. You simply don’t need to wonder if something is wrong with you code.

  • To reduce amount of bugs

It let you to know what inputs params’ function should get and what results should be returned. You simply don’t  write unused code

  • To save development time

Developers don’t waste time on checking every code’s change if his code works correctly

  • Unit tests help to understand software design
  • To provide quick feedback about method which you are testing
  • To help document a code

How to write unit test in Python

In my work I write use tests in Python. I am going to share my sample code  with you now

  • Import module unittest
  • Choose function to test
  • Write unit test

Example OpenEvent test in Python

class TestPagesUrls(OpenEventTestCase):

   def setUp(self):

       self.app = Setup.create_app()

   def test_if_urls_exist(self):

       """Test all urls via GET method"""

       with app.test_request_context():

           for rule in app.url_map.iter_rules():

               if excluded_paths(rule):

                   status_code = self.app.get(request.url[:-1] + str(rule).replace('//', '/'),        follow_redirects=True).status_code

                   self.assertTrue(status_code in [200, 302, 401])

 

I want to check if all views exist but it required a lot of time. That’s why I wonder I how to avoid writing similar tests. Finally, based  on our list of routes I am able to write test which checks code’s status  on every page.

If some of them response returns status_code different than 200, 302 or 401, test fails.This results means that somethings is wrong. Simple, isn’t it ?  Try to test it manually…. This one short test cover about 40 use cases…

This example shows an incredible value of unit tests! If developer makes a bug in response he receives an error that something is wrong with a view. Travis CI allows to reject all  wrong pull requests and merge only these which fulfill our quality requirements.   

Fixing  error is one part but finding a bug is even harder task. But an ability to detect bug on early stage of process development reduces cost of software.

FOSSASIA Event in Ho Chi Minh City

Internships

In 2012 we welcomed interns in Can Tho. Fifteen students participated in the program as full time interns in the office of MBM International in the biggest city in the Mekong delta. The program took place for 2 months and a core part of it was to learn how to use collaborative tools liker issue trackers and contribute to OpenStreetMap. Our students also love the Wikipedia sprints and we got a lot of positive vibes as everyone was happy to learn how to set up the Mediawiki software, that empowers the encyclopedia, share their ideas and spread Open Knowledge and Open Data about the Mekong Delta.

Event activities

We also continued to organize the FOSSASIA OpenTechSummit in 2010 and 2011 in Raffles College and Van Lang University in Ho Chi Minh City Vietnam. Plus we had a Mini-Debconf in Saigon and organized the event series OpenDesign.Asia Weeks bringing together designers and Open Source developers. We have links to the LXDE project and GNOME community and we have sent developers to the GNOME.Asia Summit 2012 in Hong Kong and supported the TYPO3 conference 2012 in Phnom Penh.

Also globally FOSSASIA starts to receive more attention. We have received the opportunity to introduce Asian projects at the Libre Graphics Meeting in Montreal (2011) and Brussels (2011), at the Linuxtag in Berlin (2012) and many other community events.

Please Join us and Get in Touch

The FOSSASIA organization supports activities and Open Tech development and Open Knowledge projects of the community active in Asia. If you are interested to cooperate for a project, need support for a development sprint or an event, please contact us on the FOSSASIA mailing list: http://groups.google.com/group/fossasia

How to get contributors from Asia for your Open Source project – Talk at Libre Graphics Meeting Brussels

I had the chance to talk about the topic of how to get contributors for Free/Libre/Open Source projects from Vietnam and Asia at the Libre Graphics Meeting Brussels. It was a a fantastic experience to meet developers and contributors from all over the world and I hope to support projects with the insights of this talk.

The situation in 2010 in Asia is, that many people still do not know about Free and Open Source. We need more people to support each other and help new users und developers. We need more developers in Vietnam to adapt existing solutions for Vietnamese and Asian users. We need people to organize events, where we can meet face to face. We need mentors, who developers and contributors can turn to. We need business people who understand business models and opportunities around Free and Open Source. We need you! FOSS can be a sustainable model for Vietnam as it is for other countries. Please join us in our effort for education, spreading knowledge, developement of better, faster and energy-saving software, designing easy to use interfaces and promoting opportunities for everyone with Free and Open Source.
