PyAMF blog

Google did the Ajax version of the Python shell, running on Google App Engine, we present you with the Flex version (click image to view the sample):

You can browse or download the source from the Subversion repository. You can find instructions on how to run the example yourself on the wiki page.

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.

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

In this tutorial, I’ll run through how to get a remoting server setup that deals with authentication. I’ll assume that you already have the latest version of PyAMF installed (at the time of writing, 0.1b is the most recent version).

I am going to build a WSGI remoting gateway, but you can use the principles applied here to any of the other supported gateway implementations (Django or Twisted). Check out the examples for more info.

The Socket class enables Actionscript to make socket connections and to read and write raw binary data. This example shows how to:

• use the Twisted framework and PyAMF to create a socket server
• create a connection with the socket server using Flex and Actionscript
• send the system time from Python to the Flash Player as Actionscript Date object, with an interval of 1 second

Check out the Flex example using the GeoIP APIs:

We have created a simple PyAMF example for the ByteArray class in ActionScript which provides methods and properties to optimize reading, writing, and working with binary data. The PyAMF equivalent of this class is also called ByteArray that provides the same basic functionality. (more…)
