laravel Route::controller 使用路由命名

我们知道，在 laravel 中使用 resource 的话，只需要绑定模型，在创建表单，链接时，直接可以拿来用，不需要单独的去给路由 as 别名
如

Route::resource('main','MainController');

// 创建链接

URL::route('main.index')

但是我们使用 Route::controller 时，在创建链接，尝试用以上方法访问时，就会报错
如

Route::controller('main','MainController');

// 创建链接

URL::route('main.index') // 抛出路由不存在的错误

那我们如何像使用 resource 一样方便的来使用 controller 呢？
很简单，我们打开 controller 的源码一看就知道了

// 源码路径:vendor/laravel/framework/src/Illuminate/Routing/Router.php :257 行

看到如下方法

    /**
     * Route a controller to a URI with wildcard routing.
     *
     * @param  string  $uri
     * @param  string  $controller
     * @param  array   $names
     * @return void
     */
    public function controller($uri, $controller, $names = array())
    {
        $prepended = $controller;

        // First, we will check to see if a controller prefix has been registered in
        // the route group. If it has, we will need to prefix it before trying to
        // reflect into the class instance and pull out the method for routing.
        if ( ! empty($this->groupStack))
        {
            $prepended = $this->prependGroupUses($controller);
        }

        $routable = $this->getInspector()->getRoutable($prepended, $uri);

        // When a controller is routed using this method, we use Reflection to parse
        // out all of the routable methods for the controller, then register each
        // route explicitly for the developers, so reverse routing is possible.
        foreach ($routable as $method => $routes)
        {
            foreach ($routes as $route)
            {
                $this->registerInspected($route, $controller, $method, $names);
            }
        }

        $this->addFallthroughRoute($controller, $uri);
    }

// 我们看到可以传递第三个参数，是一个数组，那么数组的内容是什么呢？此方法里面没有处理 name，我们注意看这一行

$this->registerInspected($route, $controller, $method, $names);

//好了，我们找到 registerInspected 这个方法，看他如何处理 name

     protected function registerInspected($route, $controller, $method, &$names)
    {
        $action = array('uses' => $controller.'@'.$method);

        // If a given controller method has been named, we will assign the name to the
        // controller action array, which provides for a short-cut to method naming
        // so you don't have to define an individual route for these controllers.
        $action['as'] = array_get($names, $method);

        $this->{$route['verb']}($route['uri'], $action);
    }

我们看到他以 . 去切割了 name ，然后加入了进去，这样我们就清楚很多啦
路由这样写

Route::controller(
    'options',
    'OptionsController',
    [
        'getSite'=>'options.site'
    ]
);

// 现在就可以使用创建链接啦

URL::route(‘options.site’)
