13. Challenge 3

Two little challenges:

• First, the web site http://api.geonames.org/countryInfoJSON gives information in JSON about countries and you should extract the capitals. You can use the 'demo' and '' as login and password.
• Second, the web site http://www.omdbapi.com/ offers an api to get information about movies. For example using t allows one to specify the title of a movie. Define a query to get the poster of 'The Terminator'.

13.0.1. Hints:

• Have a look at ZnEasy or ZnClient.
• To get the contents of an HTML request, send it the message contents.
• To parse and convert a string representing JSON into Pharo collection, use the STON class (check the class side).
• To pass a binding to a request, use the message queryAt:put:.
• Using the inspector is a good idea to explore objects and query results.
