Laravel 5 routing passes value to function

For example, Controller has a function

<code>public function test($var) {
    //some code...
}</code>

How to call Controller's test('abc') when defining get/abc in routes.php?
There is no need for generic variables such as Route::get(/{var}', function($var)...This is because the value of $var is fixed.

<code>Route::get('/{var}',function($var){
    return $var;
})->where('var','a|b|c|d|e|f|g');</code>

Request objects can also be obtained.

<code>// URL: /portal/orders/2
public function _test(Request $request)
{
    // 1: portal
    // 2: orders
    // 3: 2
    return Request::segment(1);
}</code>
