用lumen从0开始构造用户中心

启动项目: php -S localhost:8088 -t public/

项目初始化

• 安装lumen安装器: composer global require "laravel/lumen-installer"

• 先 lumen new user-center 初始化一个项目 或者 composer create-project --prefer-dist laravel/lumen user-center

• 执行 composer install 安装依赖包，如果是用 lumen new 命令可以省略这一步。

• 复制配置文件 cp .env.example .env

• 设置 APP_KEY 等配置信息, 因为 php artisan key:generate 没用

• 启动项目 php -S localhost:8000 -t public

引入lumen-passport

• 安装 lumen-passport 包 #

composer require dusterio/lumen-passport

• 修改 bootstrap/app.php 文件

// 集成passport
//只是取消注释
// Enable Facades
$app->withFacades();
// Enable Eloquent
$app->withEloquent();
// Enable auth middleware (shipped with Lumen)
$app->routeMiddleware([
    'auth' => App\Http\Middleware\Authenticate::class,
]);

//新增
// Finally register two service providers - original one and Lumen adapter
$app->register(Laravel\Passport\PassportServiceProvider::class);
$app->register(Dusterio\LumenPassport\PassportServiceProvider::class);

// 自定义-下面有说到, 可以之后加
// 配置-新增
$app->configure('auth');

// 开启AppServiceProvider-取消注释
$app->register(App\Providers\AppServiceProvider::class);
$app->register(App\Providers\AuthServiceProvider::class);

// $app->alias('cache', 'Illuminate\Cache\CacheManager'); //新增，解决Lumen的Cache问题

• 执行 migrate 和安装 passport

# Create new tables for Passport
php artisan migrate
# Install encryption keys and other necessary stuff for Passport
php artisan passport:install

$ php artisan migrate
Migration table created successfully.

$ php artisan passport:install

• 在根目录新建 config/auth.php 文件，加入以下内容

return [
    'defaults' => [
        'guard' => 'api',
        'passwords' => 'users',
    ],

    'guards' => [
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => \App\User::class
        ]
    ]
];

• 在 bootstrap/app.php 中引入配置文件

$app->configure('auth');

• 注册路由

Next, you should call the LumenPassport::routes method within the boot method of your application (one of your service providers). This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:

Dusterio\LumenPassport\LumenPassport::routes($this->app);

You can add that into an existing group, or add use this route registrar independently like so;

Dusterio\LumenPassport\LumenPassport::routes($this->app, ['prefix' => 'v1/oauth']);

• 并且在 .env 文件中加入几项配置项

# 环境
APP_ENV=local
# 调试
APP_DEBUG=true
# 秘钥
APP_KEY=base64:24uriVnENMM+x8u8ouLsNlE4EohGNY1mxTGWdxmPt2w=
# 时区
APP_TIMEZONE=UTC
# 语言
#APP_LOCALE
# 数据库配置
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=user_center
DB_USERNAME=root
DB_PASSWORD=
# 缓存
CACHE_DRIVER=file
# 队列
QUEUE_DRIVER=sync
# passport password grant_type client(passport进行密码授权的客户端)
APP_CLIENT_ID=2
APP_CLIENT_SECRET=bohwT7qPxj8ltPUn21nDvmMVg5DYiRgoFCZYvVh7
# passport进行密码授权时请求路径,向自己请求
APP_URL=http://www.b.com

其他环境和配置准备

• 在 app 目录下添加通用函数文件 helper.php 并且通过文件的形式自动载入， 在 composer.json 里的 autoload 添加如下代码：

    "autoload": {
        "psr-4": {
            "App\\": "app/"
        },
        "files": [
            "app/helpers.php"
        ]
    },

• 在 routes 文件下新建 api 路由文件夹， 并在 bootstrap\app.php 文件将它加载进来。

$app->group(['namespace' => 'App\Http\Controllers'], function ($app) {
    require __DIR__.'/../routes/web.php';
    require __DIR__.'/../routes/api/v1.php';
});

• 安装 dingo 包 #

composer require dingo/api:1.0.x@dev

lumen 5.5 使用下面命令

"require": {
    "dingo/api": "2.0.0-alpha1"
}

• 将 dingo 引入到 lumen

在 bootstrap/app.php 文件中引入：

$app->register(Dingo\Api\Provider\LumenServiceProvider::class);

• 在 app 目录下新增 Models 和 Serializers 和 Transformers 目录，dingo 返回数据的时候可以 transform 下

• 配置自定义配置文件

你还可以创建自定义的配置文件并使用 $app->configure() 方法来加载它们。例如，如果你的配置文件位于config/options.php，你可以像这样加载它：$app->configure('options');

• 为了刷新 token 还可以引入 Listeners

• 引入所有的 config

// config
$app->configure('app');
$app->configure('auth');
$app->configure('secrets');
$app->configure('filesystems');

通过 passport 进行鉴权

• 为了将 Unauthorized. 以状态码加提示信息的形式返回。在 Exceptions\Handler.php 目录的 render函数中加入

        switch (true) {
            case $e instanceof AuthorizationException:
                return response('This action is unauthorized.', 403);
            case $e instanceof ModelNotFoundException:
                return response('The model is not found.', 404);
        }

解决跨域问题lumen-cors【现在换成了用laravel-cors#】

// laravel-cors
composer require barryvdh/laravel-cors

在 bootstrap/app.php 文件中

// laravel-cors
// 注册 `cors` 的服务提供者
$app->register(Barryvdh\Cors\ServiceProvider::class);

$app->routeMiddleware([
    'cors' => \Barryvdh\Cors\HandleCors::class,
]);
