base64 + url encoded activation context parameter
Hi,
I wanted to send users an email with a confirmation link which
includes base64 encoded and additionally url encoded activation
context
Example:
http://my.company.com/account/confirmed/amFuZXpuOu47TZYaxgNZ297XcGQFHLQ%3D
As base64 includes characters + / and = I tried to encode it further
with URLCodec (apache commons codec) so it looks like the above
example.
But the Tapestry complains with
java.lang.IllegalArgumentException
Input string 'amFuZXpuOu47TZYaxgNZ297XcGQFHLQ=' is not valid; the
character '=' at position 32 is not valid.
which I can understand as it decodes the link automatically
Stack trace
* org.apache.tapestry5.internal.services.URLEncoderImpl.decode(URLEncoderImpl.java:143)
* org.apache.tapestry5.internal.services.ContextPathEncoderImpl.decodePath(ContextPathEncoderImpl.java:70)
* org.apache.tapestry5.internal.services.PageRenderDispatcher.process(PageRenderDispatcher.java:88)
What is the cleanest solution? Is there a known url safe
encoder/decoder which I can use or do I have to write one myself?
Regards,
Borut

Hi Borut,
right, Base 64 encoding is no good for URLs. See
"http://en.wikipedia.org/wiki/Base64#URL_applications".

I know there is one implementation included in the bouncycastle
cryptography tools, see
"http://www.bouncycastle.org/docs/docs1.6/org/bouncycastle/util/encoders/UrlBase64.html".
You'll probably find others if you google around.
Hth,
Lutz
