php - Laravel 路由可选参数

Question

我对 Laravel 路线有一个问题。

我有一个函数 index($sport = '', $date = ''); 此函数向我显示特定运动和日期的新闻。但有时这些参数没有输入，我想显示所有新闻。这工作得很好很好，问题出在路线上。

这是我使用过的路线代码:

Route::get('/news/{sport?}/{date?}.html', ['as' => 'news.index', 'uses' => 'NewsController@index']);

当没有输入运动项目和日期，URL 是domain.com/news.html，但没有被该代码捕获时，就会出现问题。我怎样才能做到这一点？

如果您将新闻和体育视为资源，您可能会拥有类似的内容:

// index case news
Route::get('/news.html', ['as' => 'news.index', 'uses' => 'NewsController@index']); 

// show case news
Route::get('/news/{date}.html', ['as' => 'news.show', 'uses' => 'NewsController@show']); 

// index case sport
Route::get('/news/sport.html', ['as' => 'sport.index', 'uses' => 'SportController@index']); 

// show case sport
Route::get('/news/sport/{date}.html', ['as' => 'sport.show', 'uses' => 'SportController@show']); 

另一种方法是:

 // index case news
Route::get('/news.html', ['as' => 'news.index', 'uses' => 'NewsController@index']); 

// sport case
Route::get('/news/{sport}.html' , ['as' => 'sport.index', 'uses' => 'SportController@index'])
     ->where(['sport' => '[0-9]+']);

// date case
Route::get('/news/{date}.html', ['as' => 'news.show', 'uses' => 'NewsController@show'])
     ->where(['date' => '[0-9]{4}-[0-9]{1,}-[0-9]{1,}']);

// sport and date case
Route::get('/news/{sport}/{date}.html' , ['as' => 'sport.index', 'uses' => 'SportController@show'])
     ->where(['sport' => '[0-9]+', 'date' => '[0-9]{4}-[0-9]{1,}-[0-9]{1,}']);
