laravel框架中路由设置，路由参数和路由命名实例

//参数一，表示uri路径
//参数二，闭包函数，处理响应
Route::get('/test', function () {
  return '测试';
});

Route::get('/', function () {});
Route::post('/', function () {});
Route::delete('/', function () {});

Route::any('/', function () {});

Route::match(['get', 'post'], '/', function () {});

Route::get('/hello', 'HelloController@index');

Route::get('/hello', 'Hello\HelloController@index');

Route::get('/list/{page}', function ($page) {
  return "当前页数{$page}";
});

Route::get('/list/{page?}', function ($page = 1) {
  return "当前页数{$page}";
});

Route::get('/search/{key?}/{page?}', function ($key = '', $page = 1) {
  return "搜索 {$key} 页数 {$page}";
})->where(['key' => '[A-Za-z]+', 'page' => '[0-9]+']);

Route::get('/search/{key?}/{page?}', function (Request $req) {
  //获取单个路由参数
  var_dump($req::route('key'));
  //获取所有路由参数
  var_dump($req::route()->parameters());
});

Route::get('/search/{key?}/{page?}', function (Request $req, $key = '', $page = 1) {

Route::get('/list/{page?}', function ($page = 1) {
  return view('list', ['page' => $page]);
})->name('list.page');

{{ route('list.page', ['page' => $page]) }}
