laravel使用中间件来指定请求的IP白名单

## 1 创建middleware中间件 ##

php artisan make:middleware GetCurrentTime

该命令会在 app/Http/Middleware 目录下创建一个新的GetCurrentTime.php文件。

<?php
    
    namespace App\Http\Middleware;
    
    use Closure;
    
    class GetCurrentTime
    {
        
        /**
         * Handle an incoming request.
         *
         * @param  \Illuminate\Http\Request  $request
         * @param  \Closure  $next
         * @return mixed
         */
        public function handle($request, Closure $next)
        {
        
            $ip=[
                '172.20.31.120',
                '172.20.31.110',
                '172.20.31.10',
                '172.20.31.12'
            ];
            if(in_array($request->getClientIp(), $ip))
            {
        
                return $next($request);
            }else{
        
                // return redirect()->to('http://textlaravel.cc');
                # 返回自定义json
                $request->headers->set('Accept', 'application/json');
                return response()->json(['noip' => '无权限访问','yesip'=>$ip]);
            }
            
        }
    }

## 2 注册中间件 ##

注册中间件分为两种：全局和路由

本文采用路由中间件

路由中使用中间件  
在app\\Http\\Kernel.php中的protected $routeMiddleware中注册路由中间件

protected $routeMiddleware = [    
        'getip'=>\App\Http\Middleware\GetCurrentTime::class,
    ];

## 3 访问带中间件的路由 ##

Route::get('/getip','TestController@getip')->middleware('getip');
