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')
这些东西找了下 laravel 文档没找着,所以自己直接看的源码
