1. Turn on Redis

 

Open your Redis Software If not, it can be in Small skin Environmental Science Installed in software management

2 .tp5 To configure config.php

'cache'                  => [
        //  Driving mode 
        'type'   => 'redis',
        //  Cache used by default 
        'default'   =>  [
            //  Driving mode

3.php Code

  function requestAccess($time=1,$limit=3){

        $ip=md5(request()->ip());
        // Get the access interface path 
        $path=request()->path();
        // take IP And the access interface path md5 Encrypted into a string , This represents the interface accessed by the same customer .
        $UV=md5($ip.$path);
        // Every IP And the number of times the interface cannot exceed per minute 
        $cacheIp=Cache::get($UV)?:0;
        if($cacheIp){

        }else{
            Cache::set($UV,1,60);
        }
        // For each request IP Address 、 Parameters and paths are spliced into an identical interface of the same user .
        $post=json_encode(request()->post());
        $name=md5($path.$post);
        // How long can each same data not be requested 
        $cache=Cache::get($name);
        if($cache==$ip){
            return false;
        }else{
            Cache::set($name,$ip,$time);
            return true;
        }
    }

4. call

When you need to limit the frequency of interface calls

if (!$this->requestAccess()){
    echo json(['code'=>200,'msg'=>' Interface calls are too frequent '])->send();die;
}
