## 一，創建過濾IP的中間件 1，創建： ~~~ liuhongdi@lhdpc:/data/php/admapi$ php think make:middleware CheckIp Middleware:app\middleware\CheckIp created successfully. ~~~ 2，代碼： middleware\\CheckIp.php [](javascript:void(0); "復制代碼") ~~~ <?php declare (strict_types = 1); namespace app\middleware; use app\result\Result; class CheckIp { //地址列表,生產環境中通常會存放在redis中 private $ipList = ['192.168.219.1','127.0.0.2']; /** * 處理請求 * * @param \think\Request $request * @param \Closure $next * @return Response */ public function handle($request, \Closure $next) { //echo "CheckIp:<br/>"; $ip = $request->ip(); if(in_array($ip,$this->ipList)){ return Result::Error(1,"IP地址錯誤"); } return $next($request); } } ~~~ [](javascript:void(0); "復制代碼") 說明：劉宏締的架構森林是一個專注架構的博客，地址：[https://www.cnblogs.com/architectforest](https://www.cnblogs.com/architectforest) ? ? ? ? ?對應的源碼可以訪問這里獲取：?[https://github.com/liuhongdi/ ](https://github.com/liuhongdi/)? ? ? ? ?或:?[https://gitee.com/liuhongdi](https://gitee.com/liuhongdi) 說明：作者:劉宏締 郵箱: 371125307@qq.com ## 二，為路由指定中間件 1,route/app.php [](javascript:void(0); "復制代碼") ~~~ <?php // +---------------------------------------------------------------------- // | ThinkPHP [ WE CAN DO IT JUST THINK ] // +---------------------------------------------------------------------- // | Copyright (c) 2006~2018 http://thinkphp.cn All rights reserved. // +---------------------------------------------------------------------- // | Licensed ( http://www.apache.org/licenses/LICENSE-2.0 ) // +---------------------------------------------------------------------- // | Author: liu21st <liu21st@gmail.com> // +---------------------------------------------------------------------- use think\facade\Route; //Route::get('article/onemedia','article/oneMedia'); Route::group('article', function () { Route::get('onemedia', 'article/oneMedia'); Route::get('qr', 'article/qr')->middleware([\app\middleware\CheckIp::class]); //Route::miss('public/miss'); }); Route::miss('article/miss'); ~~~ [](javascript:void(0); "復制代碼") 2,注意不要使CheckIp.php作為全局middleware 查看 app/middelware.php [](javascript:void(0); "復制代碼") ~~~ <?php // 全局中間件定義文件 return [ app\middleware\CheckJwt::class, app\middleware\AdminLog::class, ]; ~~~ [](javascript:void(0); "復制代碼") ## 三，測試效果 1,指定middleware時: 訪問: ~~~ http://192.168.219.6:8000/article/qr ~~~ 返回:  2,未指定middleware時: 訪問: ~~~ http://192.168.219.6:8000/article/onemedia?id=1 ~~~ 返回:
