PyAMF blog

Ohloh is a website which provides a web services suite and online community platform that aims to map the landscape of open source software development. The Ohloh API is a free, REST-based programming interface to the Ohloh open source directory. You can use the Ohloh API to create your own applications and web services based on Ohloh data. There’s a Python example client and additional examples are available for Java, Ruby, Bash, Perl, PHP and C++.

I decided to create a simple AMF gateway using PyAMF that pulls the account data from Ohloh and then passes it to a Flex application. The reason I use a AMF gateway is because I don’t want to hardcode and expose my API key in the Flex client application, which could be decompiled easily, allowing others to abuse my key.

You can test their API by entering the emailaddress of a registered Ohloh user in the input text-field below, click Submit, and it will display the user’s general account info and load the user’s avatar.

PyAMF is a lightweight library that allows Flash and Python applications to communicate via Adobe’s ActionScript Message Format.

AMF3 and RemoteObject are supported in all the implemented Remoting gateways, currently compatible with Django, Twisted, TurboGears 2, Web2Py and other WSGI supported web frameworks.

We created a Guestbook Example to demonstrate a full featured application using Flex, Twisted, and PyAMF of course. Check it out after the jump!

After Google’s announcement on Monday we received a lot of questions about running PyAMF on the Google App Engine so we decided to start working on a tutorial. This is a work in progress and might require some updates to the library. We’re also planning on setting up a demo site on our appspot but more on that later.
