With the {{Code|%perm:allow}} annotation, one or more permission strings can be attached to a RESTXQ function:
<pre classsyntaxhighlight lang="brush:xquery">
(:~ Login page (visible to everyone). :)
declare
</html>
};
</presyntaxhighlight>
The permission strings may denote ids, users, user groups, applications, or any other realms. It is completely up to the user which strings are used, and which functions will be annotated. In the given example code, only the last function has a {{Code|%perm:allow}} annotation.
** If no path argument is specified, {{Code|/}} is assigned instead.
* A variable can be specified in the second argument. A map with the following keys will be bound to that variable:
** {{Code|allow}}: Permission strings attached to the requested function; may be empty.
** {{Code|path}}: Original path of the client request.
** {{Code|method}}: Method of the client request ({{Code|GET}}, {{Code|POST}}, …).
** {{Code|authorization}}: Value of the HTTP Authorization header string; may be empty.
An example:
<pre classsyntaxhighlight lang="brush:xquery">
import module namespace Session = 'http://basex.org/modules/session';
return web:redirect('/main')
};
</presyntaxhighlight>
Some notes:
The following lines of code complete the image:
<pre classsyntaxhighlight lang="brush:xquery">
declare
%rest:path("/login-check")
web:redirect("/")
};
</presyntaxhighlight>
For a full round trip, check out the source code of the [[DBA]] that is bundled with BaseX.
