如何使用 Laravel MiddleWare 处理 Route 中的域和子域

Question

在我的 Laravel-5.8 应用程序中，我有一个使用单个数据库的多公司应用程序。每个表都有一个从公司表派生的 company_id，如下所示：

id | company_name       |    subdomain
1  | Main               |
2  | Company1           |    company1
3  | Company2           |    company2

Main=>  localhost:8888/myapp
Company1=>localhost:8888/company1.myapp
Company2=>localhost:8888/company2.myapp

我创建了一个中间件：

class VerifyDomain
{
 public function handle($request, Closure $next)
 {
    $domain == "myapp"; // your company app name
    $path = $request->getPathInfo(); // should return /company1.myapp or /company2.myapp or /myapp 
    if (strpos($path, ".") !== false) { // if path has dot.
        list($subdomain, $main) = explode('.', $path);
        if(strcmp($domain, $main) !== 0){
            abort(404); // if domain is not myapp then throw 404 page error
        }
    } else{
        if(strcmp($domain, $path) !== 0){
            abort(404); // if domain is not myapp then throw 404 page error
        }
        $subdomain = ""; // considering for main domain value is empty string.
    }

    $company = Company::where('subdomain', $subdomain)->firstOrFail(); // if not found then will throw 404

    $request->session()->put('subdomain', $company); //store it in session

    return $next($request);
 }
}

我已经在 route/web.php 中有两 (2) 个路由组，wgich 看起来像这样：

Route::get('/', ['as' => '/', 'uses' => 'IndexController@getLogin']);

Auth::routes();
Route::get('/dashboard', 'HomeController@index')->name('dashboard');

  // Config Module
  Route::group(['prefix' => 'config', 'as' => 'config.', 'namespace' => 'Config', 'middleware' => ['auth']], function () {
    Route::resource('countries', 'ConfigCountriesController');
    Route::resource('nationalities', 'ConfigNationalitiesController');
});

 // HR Module
  Route::group(['prefix' => 'hr', 'as' => 'hr.', 'namespace' => 'Hr', 'middleware' => ['auth']], function () { 
    Route::resource('designations', 'HrDesignationsController');
    Route::resource('departments', 'HrDepartmentsController');  
    Route::resource('employee_categories', 'HrEmployeeCategoriesController');

});

我有 2 个问题：

1. 如果 subdomain 字段为 null，则路由应针对主域：Main=> localhost:8888/myapp else localhost:8888/company1.myapp 或 localhost:8888/company2.myapp

2.我如何将上面的路线组容纳到这个：

 Route::domain('localhost:8888/myapp')->group(function () {
   Route::get('/', function ($id) {
       //
    });
 });

Route::domain('localhost:8888/{subdomain}.myapp')->group(function () {
   Route::get('/', function ($company_name, $id) {
       $company = Company::where('subdomain', $subdomain)->firstOrFail();
       // send the value of $company to data to send different view data 
   });
});

我不确定我是否清楚地了解你。但是，我希望你能理解我:)

首先你是“域”。我想这不是真正的域，而只是 uri。也许你应该像这样使用它：

Auth::routes();

$defaultDomain = config('myconfig.default_domain_name', 'myapp');

// I'm not reccomend to you use localhost:8888 here.
Route::domain('localhost:8888')
    ->group([
        'middleware' => ['veryfy_domain'] // Add your VerifyDomain Middleware here
    ], function () {
        // Here you already have a 'subdomain' param in session

        // If you need special logic for default domain, you can out it here
        Route::group(['prefix' => '/' . $defaultDomain], function () {
            Route::get('/', function ($id) {
               //
            });     
        });


        // Code below will work only with companies.
        Route::group(['prefix' => '/{test}.' . $defaultDomain], function () {
            Route::get('/', ['as' => '/', 'uses' => 'IndexController@getLogin']);
            Route::get('/dashboard', 'HomeController@index')->name('dashboard');

              // Config Module
            Route::group(['prefix' => 'config', 'as' => 'config.', 'namespace' => 'Config', 'middleware' => ['auth']], function () {
                Route::resource('countries', 'ConfigCountriesController');
                Route::resource('nationalities', 'ConfigNationalitiesController');
            });

             // HR Module
            Route::group(['prefix' => 'hr', 'as' => 'hr.', 'namespace' => 'Hr', 'middleware' => ['auth']], function () { 
                Route::resource('designations', 'HrDesignationsController');
                Route::resource('departments', 'HrDepartmentsController');  
                Route::resource('employee_categories', 'HrEmployeeCategoriesController');
            });
        });
    });

关于你的中间件。我是这样看的：

class VerifyDomain
{
    public function handle($request, Closure $next)
    {
        $request->get('domain_name', $this->getBaseDomain());

        $company = Company::where('subdomain', $subdomain)->firstOrFail();

        $request->session()->put('subdomain', $company);

        return $next($request);
    }

    // Better to store it in config
    protected function getBaseDomain()
    {
        return config('myconfig.default_domain_name', 'myapp');
    }
}

如果你真的想使用不同的域，我认为你的 nginx 中需要这样的东西：

server_name *.myapp myapp;

当然还有在您的主机文件中。

你可以这样检查： http://company.myapp http://company1.myapp http://myapp

配置示例：

1. 创建新文件 your_project_dir/app/config/myconfig.php（随意命名）
2. 将此代码放入文件中：

return [
  'default_domain_name' => 'myapp'
];

1. 现在您可以按照我的建议在您的代码中使用：

config('myconfig.default_domain_name');
