Laravel Blank白页

Question

我在组中获取路线时遇到问题。这是我的代码：

Route::group(['prefix' => 'commodities'], function(){
    Route::get('commodities', [
        'as' => 'showCommodities', 'uses' => 'CommodityController@showAll'
    ]);

    Route::get('{id}', [
        'as' => 'showCommodity', 'uses' => 'CommodityController@show'
    ]);

    Route::get('add', [
        'as' => 'addCommodity', 'uses' => 'CommodityController@create'
    ]);

    Route::post('update', [
        'as' => 'updateCommodity', 'uses' => 'CommodityController@update'
    ]);

    Route::post('destroy', [
        'as' => 'destroyCommodity', 'uses' => 'CommodityController@destroy'
    ]);

    Route::post('add', [
        'as' => 'storeCommodity', 'uses' => 'CommodityController@store'
    ]);
});

我在这里粘贴了CommodityController代码http://pastebin.com/bWrdVhsv

除GET路线commodites/add外，一切正常。我总是得到一个白页。我的调试设置为TRUE，我有正确的刀片。

我在这里错过了什么吗？

问题在于路线的顺序。

将add路线移至所有{id}路线上方。

Route::group(['prefix' => 'commodities'], function(){
    Route::get('commodities', [
        'as' => 'showCommodities', 'uses' => 'CommodityController@showAll'
    ]);

    Route::get('add', [
        'as' => 'addCommodity', 'uses' => 'CommodityController@create'
    ]);

    Route::get('{id}', [
        'as' => 'showCommodity', 'uses' => 'CommodityController@show'
    ]);

    Route::post('update', [
        'as' => 'updateCommodity', 'uses' => 'CommodityController@update'
    ]);

    Route::post('destroy', [
        'as' => 'destroyCommodity', 'uses' => 'CommodityController@destroy'
    ]);

    Route::post('add', [
        'as' => 'storeCommodity', 'uses' => 'CommodityController@store'
    ]);
});

Laravel将从头到尾浏览您的routes.php文件。以下路线基本上是一个全部捕获。

Route::get('{id}', [
        'as' => 'showCommodity', 'uses' => 'CommodityController@show'
]);

这意味着它将捕获与模式匹配的网址的所有GET请求：

/commodities/some-kind-of-string。

当/commodities/add uri与上述模式匹配时，它将使用该路由，因为它首先出现在路径文件中。
