本篇文章给大家分享的内容是关于如何在Laravel 5.1中进行自定义包的开发，步骤很清晰，有着一定的参考价值，希望可以帮助到有需要的朋友。

1、安装Laravel

已安装Laravel的略过本步骤，未安装的参考Laravel安装文档：Laravel 5.1安装及配置

2、创建目录和服务提供者

在根目录下创建文件夹 packages/jai/contact/src

进入src目录并创建一个服务提供者ContactServiceprovider.php：

<?php namespace Jai\Contact;
use Illuminate\Support\ServiceProvider;
use Illuminate\Routing\Router;
class ContactServiceprovider extends ServiceProvider
{
    /**
     * Indicates if loading of the provider is deferred.
     *
     * @var bool
     */
    protected $defer = false;
    public function boot()
    {
        $this->loadViewsFrom(realpath(__DIR__.&#39;/../views&#39;), &#39;contact&#39;);
        $this->setupRoutes($this->app->router);
        // this for conig
        $this->publishes([
            __DIR__.&#39;/config/contact.php&#39; => config_path(&#39;contact.php&#39;),
        ]);
    }
    /**
     * Define the routes for the application.
     *
     * @param \Illuminate\Routing\Router $router
     * @return void
     */
    public function setupRoutes(Router $router)
    {
        $router->group([&#39;namespace&#39; => &#39;Jai\Contact\Http\Controllers&#39;], function($router)
        {
            require __DIR__.&#39;/Http/routes.php&#39;;
        });
    }
    public function register()
    {
        $this->registerContact();
        config([
            &#39;config/contact.php&#39;,
        ]);
    }
    private function registerContact()
    {
        $this->app->bind(&#39;contact&#39;,function($app){
            return new Contact($app);
        });
    }
}

创建路由

在src目录下新建一个Http目录并在其中创建一个routes.php：

<?php
Route::get(&#39;contact&#39;, &#39;ContactController@index&#39;);

创建控制器

在Http目录下新建Controllers目录并在其中创建控制器ContactController.php：

<?php namespace Jai\Contact\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Config;
class ContactController extends Controller
{
    /**
     * Show the application welcome screen to the user.
     *
     * @return Response
     */
    public function index()
    {
        dd(Config::get("contact.message"));
        return view(&#39;contact::contact&#39;);
    }
}

创建配置文件

在src目录下新建config目录并在其中创建配置文件contact.php：

<?php
    return [
        "message" => "Welcome to your new package"
    ];

创建视图文件

在packages/jai/contact目录下创建views文件夹，并在其中创建视图文件template.blade.php：

<html>
    <head>
        <meta charset="UTF-8">
        <title>title</title>
    </head>
    <body>
        @yield(&#39;content&#39;)
    </body>
</html>

和视图文件contact.blade.php：

@extends(&#39;contact::template&#39;)
@section(&#39;content&#39;)
Laravel Academy
@stop

最终生成的目录结构如下：

3、添加包路径到composer.json

在根目录下修改composer.json，将"Jai\\Contact\\": "packages/jai/contact/src/"添加到psr-4：

"psr-4": {
    "App\\": "app/",
    "Jai\\Contact\\": "packages/jai/contact/src/"
}

4、注册服务提供者

在Laravel应用根目录下修改config/app.php，将服务提供者追加到providers数组：

Jai\Contact\ContactServiceProvider::class

5、加载包并发布资源

完成上述操作之后还要在命令行执行两个命令，首先在应用根目录下运行

composer dump-autoload

来更新Composer的autoloader，然后运行

php artisan vendor:publish

将自定义包的配置文件发布到应用根目录的config目录下以便可以访问。

6、在浏览器中测试

完成上述操作后即可在浏览器中访问http://laravel.app:8000/contact,页面输出如下：

"Welcome to your new package"

修改ContactController.php的代码如下：

//dd(Config::get("contact.message"));
return view(&#39;contact::contact&#39;);

则页面输出为：

Laravel Academy

至此，表明我们的自定义包开发完成并通过测试。
