# Catalyst::ActionRole::Scheme(3pm)

Match on HTTP Request Scheme

## NAME

Catalyst::ActionRole::Scheme - Match on HTTP Request Scheme

## SYNOPSIS

```
    package MyApp::Web::Controller::MyController;
    use base 'Catalyst::Controller';
    sub is_http :Path(scheme) Scheme(http) Args(0) {
      my ($self, $c) = @_;
      Test::More::is $c->action->scheme, 'http';
      $c->response->body("is_http");
    }
    sub is_https :Path(scheme) Scheme(https) Args(0)  {
      my ($self, $c) = @_;
      Test::More::is $c->action->scheme, 'https';
      $c->response->body("is_https");
    }
    1;
```

## DESCRIPTION

This is an action role that lets your Catalyst::Action match on the scheme type of the request.  Typically this is `"http"` or `"https"` but other common schemes that Catalyst can handle include `"ws"` and `"wss"` (web socket and web socket secure).

This also ensures that if you use `"uri_for"` on an action that specifies a match scheme, that the generated URI object sets its scheme to that automatically (rather than the scheme of the current request object, which is and remains the default behavior.)

For matching purposes, we match strings but the casing is insensitive.

## REQUIRES

This role requires the following methods in the consuming class.

### match

### match\_captures

Returns 1 if the action matches the existing request and zero if not.

## METHODS

This role defines the following methods

### match

### match\_captures

Around method modifier that return 1 if the scheme matches

### list\_extra\_info

Add the scheme declaration if present to the debug screen.
