Subject [jira] [Commented] (SHIRO-459) Support role-based authorization depending on HTTP request method
Date Thu, 19 Sep 2013 14:57:51 GMT

    [ https://issues.apache.org/jira/browse/SHIRO-459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13771951#comment-13771951

Daniel Bimschas commented on SHIRO-459:
---------------------------------------

Quite obviously the implementation should have some documentation (e.g., on how to use it).
I would be happy to add it if you think this implementation is fine.

Also I wonder if it is possible or sensible to not always parse the authorization settings
for every request. Does this make sense? Or is Shiro reading the configuration every time
a request is authorized (thereby allowing changing authorization settings at runtime)? Or
are servlet filters instantiated for every request whatsoever?

> Dear Shiro gods!
> I'm struggling to figure out how I can do role-based authorization depending on what
HTTP method a request is using. I've posted this question on StackOverflow as it seems nobody
has been asking it before (at least I couldn't find it with my search terms). I would be incredibly
happy if you could take a look!

> =============================
> Then, in a second mail I proposed a solution to the issue:
> =============================
> Digging into the Shiro source codes I found that this feature is in fact not available
in Shiro. I've now implemented my own custom filter (extending RolesAuthorizationFilter) that
allows you to do exactly what I wanted. Configuration for the filter follows the following
example:
> [main]
>  myFilter=my.package.HttpMethodRolesAuthorizationFilter
> [urls]
>  /rest = authcBasic, myFilter[PUT=SERVICE_PROVIDER&EXPERIMENTER,POST=EXPERIMENTER,DELETE=ADMINISTRATOR]
> So, in this example
> - a user must be authenticated to execute any operation
> - a user with both roles SERVICE_PROVIDER and EXPERIMENTER can send a PUT request,
> - a user with role EXPERIMENTER can send POST requests, and
> - a user with role ADMINISTRATOR can DELETE things
> I would be more than happy to contribute this little bit of code to the project in case
you're interested!
