第一步：添加app\http\Controllers文件夾里面創建我們要存放前端和后端或者接口的文件夾

列如： Home(前端) Admin(后端) App(接口) 文件夾

第二步：修改app\http\providers\RouteServiceProvider.php

1. <?php
2.  
3. namespace App\Providers;
4.  
5. use Illuminate\Support\Facades\Route;
6. use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
7.  
8. class RouteServiceProvider extends ServiceProvider
9. {
10. /**
11. * This namespace is applied to your controller routes.
12. *
13. * In addition, it is set as the URL generator's root namespace.
14. *
15. * @var string
16. */
17. protected $namespace = 'App\Http\Controllers';
18. protected $homeNamespace = 'App\Http\Controllers\Home';//PC端
19. protected $adminNamespace = 'App\Http\Controllers\Admin';//管理后臺
20.  
21. /**
22. * Define your route model bindings, pattern filters, etc.
23. *
24. * @return void
25. */
26. public function boot()
27. {
28. //
29.  
30. parent::boot();
31. }
32.  
33. /**
34. * Define the routes for the application.
35. *
36. * @return void
37. */
38. public function map()
39. {
40. //$this->mapApiRoutes();
41.  
42. //$this->mapWebRoutes();
43. $sld_prefix = explode('.',$_SERVER['HTTP_HOST'])[0];
44. if(config('route.admin_url') == $sld_prefix){
45. $this->mapAdminRoutes();
46. }elseif(config('route.home_url') == $sld_prefix){
47. $this->mapHomeRoutes();
48. }elseif(config('route.api_url') == $sld_prefix){
49. $this->mapApiRoutes();
50. }
51. }
52.  
53. /**
54. * Define the "web" routes for the application.
55. *
56. * These routes all receive session state, CSRF protection, etc.
57. *
58. * @return void
59. */
60. protected function mapWebRoutes()
61. {
62. Route::middleware('web')
63. ->namespace($this->namespace)
64. ->group(base_path('routes/web.php'));
65. }
66.  
67. /**
68. * Define the "api" routes for the application.
69. *
70. * These routes are typically stateless.
71. *
72. * @return void
73. */
74. protected function mapApiRoutes()
75. {
76. Route::prefix('api')
77. ->middleware('api')
78. ->namespace($this->namespace)
79. ->group(base_path('routes/api.php'));
80. }
81.  
82. /**
83. * 管理后臺
84. */
85. protected function mapAdminRoutes()
86. {
87. Route::middleware('web')
88. ->namespace($this->adminNamespace)
89. ->group(base_path('routes/admin.php'));
90. }
91.  
92. /**
93. * PC端
94. */
95. protected function mapHomeRoutes()
96. {
97. Route::middleware('web')
98. ->namespace($this->homeNamespace)
99. ->group(base_path('routes/home.php'));
100. }
101. }

第三步：在routes目錄下創建admin.php 和home.php 路由

第四步：分別在app\Http\Controllers\Admin和app\Http\Controllers\Home

1. <?php
2. namespace App\Http\Controllers\Admin;
3. use App\Http\Controllers\Controller;
4.  
5. class AdminController extends Controller
6. {
7. public function index()
8. {
9. echo "this is admin";
10. }
11. }

1. <?php
2. namespace App\Http\Controllers\Home;
3. use App\Http\Controllers\Controller;
4.  
5. class HomeController extends Controller
6. {
7. public function index()
8. {
9. echo "this is home";
10. }
11. }

第五步：分別在admin.php 和home.php 新建路由

Route::get('/', 'AdminController@index');

Route::get('/','HomeController@index');

第六步：測試

第七步：運行報錯

錯誤一：laravel Class ‘App\Http\Controllers\Controller' not found

錯誤二：Class App\Http\Controllers\IndexController does not exist

解決方法：

在PHPstorm Terminal控制臺輸入“composer dump-autoload”

因為laravel是用composer來加載類，不是命令創建的類要更新autoload。

如果沒有使用PHPstorm編輯器的話，我們需要在本地安裝composer，然后cmd以管理員運行，進入到項目的根目錄執行“composer dump-autoload”
