为什么api.php和web.php路由文件在heruko上不起作用？

Question

希望一切都很好。我已经将laravel应用程序部署到了heruko。

这是我的htacss文件：

<IfModule mod_rewrite.c>
    RewriteEngine on
    RewriteCond %{REQUEST_URI} !^public
    RewriteRule ^(.*)$ public/index.php?$1 [END,QSA]
</IfModule>

我的路线文件夹中也有

1- api.php

use Illuminate\Http\Request;
Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

Route::middleware('cors:api')->get('/stores', function (Request $request, Response $response) {
    return App::make('App\Http\Controllers\ApiData')->{'GetStores'}();
});

Route::middleware('cors:api')->post('/RegisterLocation', function (Request $request, Response $response) {
    return App::make('App\Http\Controllers\ApiData')->{'RegisterLocation'}();
});

Route::middleware('cors:api')->post('/SearchPartner', function (Request $request, Response $response) {
    return App::make('App\Http\Controllers\ApiData')->{'SearchPartner'}();
});


and 

Web.php 

<?php
Route::get('/', function () {
   //Route::get('/', 'UserController@show');
   return view('welcome');
});

Route::get('/stores', function() {
    return App::make('App\Http\Controllers\UserController')->{'show'}();
});

我输入的任何网址如何将我重定向到索引页？

任何原因吗？

谢谢。
