在 Laravel 8 中参考 igaster / laravel-theme 示例实现

• 大前端, 编程笔记

1、在本地使用 Composer 来创建一个新的 Laravel 项目：laravel-theme-demo。

PS E:/wwwroot> composer create-project laravel/laravel laravel-theme-demo
Creating a "laravel/laravel" project at "./laravel-theme-demo"
Installing laravel/laravel (v8.6.10)
  - Installing laravel/laravel (v8.6.10): Extracting archive
Created project in E:/wwwroot/laravel-theme-demo
> @php -r "file_exists('.env') || copy('.env.example', '.env');"

Updating dependencies
Lock file operations: 110 installs, 0 updates, 0 removals

2、igaster / laravel-theme 是一个 Laravel 包，增加了对管理主题的基本支持。它允许您在单独的文件夹中构建视图和资产，并支持主题扩展。执行命令：composer require “igaster/laravel-theme”，以安装 igaster/laravel-theme。

PS E:/wwwroot/laravel-theme-demo> composer require "igaster/laravel-theme"
Using version ^2.0 for igaster/laravel-theme
./composer.json has been updated
Running composer update igaster/laravel-theme

3、安装 Laravel Mix，执行：yarn install，运行所有的 Mix 任务，执行：npm run dev。

PS E:/wwwroot/laravel-theme-demo> yarn install

4、将配置文件发布到您的应用程序

PS E:/wwwroot/laravel-theme-demo> php artisan vendor:publish --provider="Igaster/LaravelTheme/themeServiceProvider"
Copied File [/vendor/igaster/laravel-theme/src/Config/themes.php] To [/config/themes.php]
Publishing complete.

5、创建主题，执行命令：theme:create。生成目录结构，如法炮制，生成主题 t2。如图1

创建主题，执行命令：theme:create。生成目录结构，如法炮制，生成主题 t2

图1

PS E:/wwwroot/laravel-theme-demo> php artisan theme:create

 Give theme name::
 > t1

 Where will views be located? [t1]:
 >

 Where will assets be located? [t1]:
 >

 Extends an other theme? (yes/no) [no]:
 >

Summary:
- Theme name: t1
- Views Path: E:/wwwroot/laravel-theme-demo/resources/views/t1
- Asset Path: E:/wwwroot/laravel-theme-demo/public/t1
- Extends Theme: No

 Create Theme? (yes/no) [yes]:
 > yes
PS E:/wwwroot/laravel-theme-demo> php artisan theme:create

 Give theme name::
 > t2

 Where will views be located? [t2]:
 >

 Where will assets be located? [t2]:
 >

 Extends an other theme? (yes/no) [no]:
 >

Summary:
- Theme name: t2
- Views Path: E:/wwwroot/laravel-theme-demo/resources/views/t2
- Asset Path: E:/wwwroot/laravel-theme-demo/public/t2
- Extends Theme: No

 Create Theme? (yes/no) [yes]:
 > yes

6、打开首页：http://laravel-theme-demo.local/ ，默认的界面。如图2

7、使用中间件设置主题，执行命令：php artisan make:middleware SetTheme

PS E:/wwwroot/laravel-theme-demo> php artisan make:middleware SetTheme
Middleware created successfully.

8、在 app/Http/Kernel.php 文件中注册你的中间件。 例如，如果您想将主题应用于所有路由，则应将其添加到 web 数组中。

    /**
     * The application's route middleware groups.
     *
     * @var array<string, array<int, class-string|string>>
     */
    protected $middlewareGroups = [
        'web' => [
            // ...
            /App/Http/Middleware/SetTheme::class,
        ],
    ];

9、添加文件：public/images/test.gif、public/t1/images/test.gif、public/t2/images/test.gif，编辑主题文件：resources/views/welcome.blade.php、resources/views/welcome.blade.php、resources/views/welcome.blade.php，其内容完全一样
