因為專案需要，隱藏url中的敏感路徑，就使用到了Tp5中的專案下route.php，但是按著手冊修改route.php後在後臺控制器中獲取不到引數值：

1、前提在config.php中新增：

'url_route_on'  =>  true,  //開啟路由

2、然後修改專案下 例如application/route.php
Route::bind('index'); //繫結模組
//批量註冊變數
Route::pattern([
  'name' => '\w+',
  'id' => '\d+',
  'p' => '\d+'
]);
//路由規則
Route::get([
    'jiameng/:name'=>['index/listShow',[],['name'=>'\w+']],
]);

public function listShow()
{
   print_r($_GET); //獲取不到資料
   dump(request()); //資料如下
}

說明name在request中的route中是存在的。

後來直接在控制中列印：

var_dump(request()->route('name'));  //輸出 feiyong

4、檢視原始碼後發現可以直接在控制器下的方法中傳遞形參可以減少程式碼量 優化為：

public function listShow($name)
{
        echo $name; //輸出為  feiyong   
}

至此就可以愉快的玩耍route了
