一，创建一个middleware

liuhongdi@lhdpc:/data/php/admapi$ php think make:middleware CheckIp
Middleware:app\middleware\CheckIp created successfully.

二，编写php代码:

1, middleware/CheckIp.php  

<?php
declare (strict_types = 1);
 
namespace app\middleware;
 
use app\result\Result;
 
class CheckIp
{
    //地址列表,生产环境中通常会在redis中
    private $ipList = ['192.168.219.1','127.0.0.2'];
    /**
     * 处理请求
     *
     * @param \think\Request $request
     * @param \Closure       $next
     * @return Response
     */
    public function handle($request, \Closure $next)
    {
        //得到当前IP
        $ip = $request->ip();
        //判断是否在列表中
        if(in_array($ip,$this->ipList)){
            return Result::Error(1,"IP地址错误");
        }
        return $next($request);
    }
}

2,middleware.php

<?php
// 全局中间件定义文件
return [
    // 全局请求缓存
    // \think\middleware\CheckRequestCache::class,
    // 多语言加载
    // \think\middleware\LoadLangPack::class,
    // Session初始化
    // \think\middleware\SessionInit::class
    //调用对ip地址的检查
    app\middleware\CheckIp::class,
];

3,result/Result.php

<?php
 
namespace app\result;
 
use think\response\Json;
 
class Result {
    //success
    static public function Success($data):Json {
        $rs = [
            'code'=>0,
            'msg'=>"success",
            'data'=>$data,
        ];
        return json($rs);
    }
    //error
    static public function Error($code,$msg):Json {
        $rs = [
            'code'=>$code,
            'msg'=>$msg,
            'data'=>"",
        ];
        return json($rs);
    }
}

三，测试效果

1,当ip地址匹配时： 访问:

http://192.168.219.6:8000/article/onemedia?id=1

返回:   2，当ip地址不匹配时: 访问:

http://127.0.0.1:8000/article/onemedia?id=1

返回:  

四，查看php和thinkphp的版本:
