Route::pattem('id', '[0-9]+

Route的放置順序很重要

id限定格視為數字

//id限制格式
Route::pattern('id', '[0-9]+');
Route::get('/', 'PostController@index');Route::get('posts', 'PostController@index');Route::get('/posts/{id}', 'PostController@show');

Route::get('/test', function(){    $user = \App\Post::with('user')->find(1);    dd($user);});
