Today we'll take a look at url encoding and decoding in VA Smalltalk. When making HTTP requests and posts, it's quite common to have to deal with encoded content. Fortunately, it's easy to do in VA. To Encode, we'll use an url:


"encode an url"
url := 'http://www.jarober.com/blog/blogView?entry=3506669370'.
encoded := url sstUrlEncode.
^encoded. 

'http://www.jarober.com/blog/blogView?entry=3506669370'

You can see the encoded text right there. Now the reverse - decoding an encoded string:


"decode"
decoded := encoded sstUrlDecodeQueryComponent.
^decoded

 'http://www.jarober.com/blog/blogView?entry=3506669370'

And there's the result, back in its original form. That's all there is to it.
