In OpenRasta is it possible to Pattern match multiple key/value pairs?

Is it possible in OpenRasta to have a Uri pattern that allows for an array of values of the same key to be submitted and mapped to a handler method accepting an array of the query parameters.

Example: Return all the contacts named Dave Smith from a collection.

HTTP GET /contacts?filterBy=first&filterValue=Dave&filterBy=last&filterValue=Smith

With a configuration of:

What syn开发者_运维技巧tax would be best for the Uri string pattern matching? (Suggestions welcome)

ResourceSpace.Has.ResourcesOfType<List<ContactResource>>()
    .AtUri("/contacts")
    .And.AtUri("/contacts?filterBy[]={filterBy}[]&filterValue[]={fv}[]") // Option 1
    .And.AtUri("/contacts?filterBy={filterBy}[]&fv={fv}[]") // Option 2

Would map to a Handler method of:

public object Get(params Filter[] filters)
{
    /*
    create a Linq Expression based on the filters using dynamic linq
    query the repository using the Linq
    */

    return Query.All<Contact>().Where(c => c.First == "Dave" && c.Last == "Smith").ToResource()
}

where Filter is defined by

public class Filter
{
    public string FilterBy { get; set; }
    public string FilterValue { get; set; }
}

.AtUri("/contacts?filterBy={filterby}&filterValue={filterValue}") should happily map to

Post(string[] filterby, string[] filterValues)

That should get processed the correct way, if not it's a bug.

You can also use the object syntax if you want something a bit nicer:

<input name="Filter:0.FilterBy" />
<input name="Filter:1.FilterBy" />

and have

Post(IEnuemrable<Filter> filter)

But you will probably need to use a post for this, not a get. The usual way to solve this is to do a Post-Redirect-Get to a fully built URI, which is also nicer for caching
