好久没写 php 代码，有需求要写一个内部使用的包，折腾了半天，用最简单的代码写下来备份一下流程

 

Step1. 初始化 laravel 项目

composer create-project laravel/laravel laravel-package

 

Step2. 创建目录，初始化 composer.json

➜  mkdir -p  app/packages/jesseychen/package-test  
➜  cd app/packages/jesseychen/package-test
➜  composer init
➜  mkdir src
➜  touch README.md
➜  cd src
➜  touch Test.php TestServiceProvider.php
#  jesseychen是用户名，表示谁的包
#  package-test 为拓展包的包名

 

 

Step3. 实现拓展包的内容

Test.php

<?php

namespace JesseyChenPackageTest;

class Test
{
    public function execute()
    {
        echo 'this is a test. ';
    }
}

TestServiceProvider.php

<?php

namespace JesseyChenPackageTest;

use IlluminateSupportServiceProvider;

class TestServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton('test', function () {
            return new Test();
        });
    }
}

composer.json

{
    "name": "jesseychen/package-test",
    "description": "This is a test.",
    "type": "library",
    "license": "MIT",
    "authors": [
        {
            "name": "summer",
            "email": "chenjunxing1012@gmail.com"
        }
    ],
    "minimum-stability": "dev",
    "require": {},
    "autoload": {
        "psr-4": {
            "JesseyChen\PackageTest\": "src/"
        }
    }
}

 

Step4. 在 laravel 项目引入本地拓展包

1. 编辑 laravel 项目文件的 composer.json

   .... ，
   "repositories": {
       "jesseyChen": {
           "type": "path",
           "url": "/var/www/laravel-package/app/packages/jesseychen/package-test"
       }
   }
   # 注意 “url” 为绝对路径

2. 安装拓展包

   composer require jesseychen/package-test:dev-master

安装完会发现 jesseychen/package-test 出现在 laravel/vendor

 

此时编辑 app/packages/jesseychen/package-test 目录内的文件，laravel/vendor/jesseychen/package-test 目录的文件会跟着改变，相当做了文件映射，这样方便本地调试

3. 把 service 注册到 laravel 项目中，在 config/app.php 添加

   'providers' => [
   
       /*
        * Laravel Framework Service Providers...
        */
        ....
   
       /*
        * Package Service Providers...
        */
       JesseyChenPackageTestTestServiceProvider::class,
       /*
        * Application Service Providers...
        */
       ....
   ],

 

Step5. 测试

1. 编辑 route/web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    app('test')->execute();
});

添加配置文件 config

1. 在 src 下创建 config 目录来存取我们的配置参数文件 config/test.php

<?php
return [
    'key' => 'jessey',
    'value' => 10
];

2. 编辑 TestServiceProvider.php.

<?php

namespace JesseyChenPackageTest;

use IlluminateSupportServiceProvider;

class TestServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton('test', function () {
            return new Test();
        });
    }

    public function boot()
    {
        $this->publishes([
            __DIR__ . '/config/test.php' => config_path('test.php'),
        ]);
    }
}

3. 发布配置文件 php artisan vendor:publish

   

    

4. 编写 Test.php

<?php

namespace JesseyChenPackageTest;

class Test
{

    public function execute()
    {
        echo 'This is a test..';
    }

    public function getConfig()
    {
        var_dump(config('test'));
    }
}

5. 测试 vim route/web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    app('test')->getConfig();
});

---

 

添加门面 Facade

1. src 目录下创建 Facade.php

<?php

namespace JesseyChenPackageTest;

use IlluminateSupportFacadesFacade as LaravelFacade;

class Facade extends LaravelFacade
{
    protected static function getFacadeAccessor()
    {
        return 'test';
    }
}

2. 在 app/config 目录注册 Facade 类

   'aliases' => [
       ....,
       'Test' => JesseyChenPackageTestFacade::class
   ],

3. 测试，vim route/web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    Test::execute();
});

发布拓展包到 https://packagist.org

 

1. 首选把 package-test 包 上传到 github 或者 coding

➜  cd app/packages/jesseychen/package-test 
➜  git init
➜  git add .
➜  git commit -m 'init package'
➜  git remote add origin https://github.com/JesseyChen/package-test.git
➜  git push -u origin master
➜  git tag 1.0
➜  git push --tag

vim package-test/composer.json ，添加 "version"

{
    ...
    "version": "1.0",
}

 

2. 上传到 https://packagist.org/

1. 点击右上角的 submit
   
   

    
2. 把 github 上 https 的链接 cv 后 check
   
   

    
3. 成功后，出现下图
   
   

    
   
   以后更新拓展包，把本地新代码提交到 github 后，点击图上的 update 同步最新的代码

 

3. 测试

先删除本地的包

1. 删除 composer.json 的 "repositories"、"require" 的 "jesseychen/package-test": "dev-master",
2. 注释掉 config/app.php 内刚刚添加的 providers 和 aliases
3. 执行 composer update

安装

composer clear-cache 
composer require "jesseychen/package-test:1.0"
