use think\cache\driver\Redis;
$post=$this->request->post();
$redis=new Redis();
$post['time'] = time();
// 转md5
$key = "checkRepeat:" . md5(json_encode($post));
if($redis->has($key)){
return json(['code'=>400,'msg'=>'正在处理中，请勿重复提交！']);
}
// 缓存时间(10秒)
$redis->set($key, 1, 10);
升级版，比上面管用
$post=$this->request->post();
$time=time();
$key = "checkRepeat:" . md5(json_encode($post));// 转md5
if($redis->has($key)){
$data=$redis->get($key);
$t=time()-$data;
if($t<5){
return json(['code'=>400,'msg'=>'5秒之内只能提交一次！']);
}
}
$redis->set($key, $time, 10);// 缓存时间(10秒)
