如何在Laravel 4中基于用户类型制作路由过滤器? [英] How to make a route filters base on user type in Laravel 4?

问题描述

目标:我想使用Route::group和Route::filter

---

说明

我有2种类型的用户:

1. 内部
2. 发行人

对于Internal，我有2个小组:

• 管理员
• 常规

对于Distributor，我有4个小组:

• 黄金
• 银
• 青铜
• oem

符合条件的路线

OEM分销商仅可使用5条路线.

OEM Distributor are eligible for only 5 routes.

Route::get('distributors/{id}', array('before' =>'profile', 'uses'=>'DistributorController@show'));
Route::get('distributors/{id}/edit', 'DistributorController@edit');
Route::put('distributors/{id}/update', array('as'=>'distributors.update', 'uses'=>'DistributorController@update'));
Route::get('catalog_downloads','CatalogDownloadController@index');
Route::get('catalog_downloads/{id}/download','CatalogDownloadController@file_download');

常规分销商可使用8条路线.

Regular Distributor are eligible for 8 routes.

Route::get('distributors/{id}', array('before' =>'profile', 'uses'=>'DistributorController@show'));
Route::get('distributors/{id}/edit', 'DistributorController@edit');
Route::put('distributors/{id}/update', array('as'=>'distributors.update', 'uses'=>'DistributorController@update'));
Route::get('catalog_downloads','CatalogDownloadController@index');
Route::get('catalog_downloads/{id}/download','CatalogDownloadController@file_download');
Route::get('marketing_materials','MarketingMaterialController@index');
Route::get('marketing_materials/{id}/download/thumb_path','MarketingMaterialController@thumb_download');
Route::get('marketing_materials/{id}/download/media_path','MarketingMaterialController@media_download');

代码

• filters.php
• routes.php .
• filters.php
• routes.php.

• 有人可以帮助我，或者至少将我引导到正确的方向吗?
• Can someone please help me or at least direct me to the right direction ?

推荐答案

首先:声明两次输入相同URL 的路由是不可能的.无论是否在一个小组中. (如果您有一个prefix组，则可能是因为前缀更改为路由的URL)

First off: It's not possibble to declare a route that results in the same URL twice. Whether it's in a group or not. (Well if you have a group with prefix it's possible because a prefix changes to URL of the route)

您必须通过智能过滤

这是我想出的最简单的解决方案:

This is the simplest solution I've come up with:

Route::filter('distributor', function(){
    $user = Auth::user();
    if($user->type == "Distributor"){
        return true;
    }
    if (Request::ajax()){
        return Response::make('Unauthorized', 404);
    }
    return View::make('errors.404_auth');
});

Route::filter('distributor.regular', function(){
    $user = Auth::user();
    if($user->type == "Distributor"){
        if($user->distributor()->type != 'OEM'){
            return true;
        }
    }
    if (Request::ajax()){
        return Response::make('Unauthorized', 404);
    }
    return View::make('errors.404_auth');
});

distributor筛选器检查用户是否为Distributor类型.第二个筛选器distributor.regular检查分发者是否不是OEM. (如果您想知道，distributor.regular中的点没有特殊功能或更深层的含义.我只想这样写)

The distributor filter checks just if the user is of type Distributor. The second filter, distributor.regular, checks if the distributor is not an OEM. (If you're wondering, the dot in distributor.regular has no special function or deeper meaning. I just like to write it like that)

Route::group(['before' => 'distributor'], function(){
    Route::get('distributors/{id}', array('before' =>'profile', 'uses'=>'DistributorController@show'));
    Route::get('distributors/{id}/edit', 'DistributorController@edit');
    Route::put('distributors/{id}/update', array('as'=>'distributors.update', 'uses'=>'DistributorController@update'));
    Route::get('catalog_downloads','CatalogDownloadController@index');
    Route::get('catalog_downloads/{id}/download','CatalogDownloadController@file_download');

    Route::group(['before' => 'distributor.regular'], function(){
        Route::get('catalog_downloads', 'CatalogDownloadController@index');
        Route::get('catalog_downloads/{id}/download', 'CatalogDownloadController@file_download');
        Route::get('marketing_materials', 'MarketingMaterialController@index');
        Route::get('marketing_materials/{id}/download/thumb_path', 'MarketingMaterialController@thumb_download');
        Route::get('marketing_materials/{id}/download/media_path', 'MarketingMaterialController@media_download');
    });
});

这应该已经适用于您发布的用例.但是，我们可以使过滤器更灵活，并减少冗余代码.

This should already work with the use-cases you posted. However we can make the filters more flexible and also reduce redundant code.

function makeError404(){
    if (Request::ajax()){
        return Response::make('Unauthorized', 404);
    }
    return View::make('errors.404_auth');
}

Route::filter('distributor', function(){
    $user = Auth::user();
    if($user->type == "Distributor"){
        return true;
    }
    return makeError404();
});

Route::filter('distributor.group', function($route, $request, $value){
    $groups = explode(';', $value);
    $user = Auth::user();
    if($user->type == "Distributor"){
        if(in_array($user->distributor()->type, $groups)){
            return true;
        }
    }
    return makeError404();
});

现在，我们可以动态指定用户必须属于哪个组...

Now we can dynamically specify in which group the user has to be...

Route::group(['before' => 'distributor'], function(){
    // distributor routes

    Route::group(['before' => 'distributor.group:gold;silver;bronze'], function(){
        // regular routes
    });
});
