RESTFul Extension Detection
Usage
ColdBox allows you to detect incoming extensions from incoming paths automatically for you. This is great for building multi-type responses or to just create virtual extensions for events.
1
http://localhost/users
2
http://localhost/users.json
3
http://localhost/users.xml
4
http://localhost/users.pdf
5
http://localhost/users.html
Copied!
If an extension is detected in the incoming URL, ColdBox will grab it and store it in the request collection (
RC) as the variable format. If there is no extension, then rc.format will not be stored and thus will not exist.1
http://localhost/users => rc.format is null, does not exist
2
http://localhost/users.json => rc.format = json
3
http://localhost/users.xml => rc.format = xml
4
http://localhost/users.pdf => rc.format = pdf
5
http://localhost/users.html => rc.format = html
Copied!
Configuration
You can configure the extension detection using the following configuration methods:
