<?php

namespace App\Http\Middleware;

use App\Exceptions\InvalidRequestException;
use Closure;
use Illuminate\Support\Facades\Redis;

class PreventDupSubmit
{
    /**
     * 简单的防止前端重复提交数据 导致的数据异常
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {

        $requestParams = $request->all();
        $requestParams["adminId"] = getAdminUserId();
        $requestParams["uri"] = $request->getUri();
        ksort($requestParams);
        $key = md5(serialize($requestParams));
        $result = Redis::Connection("wms")->set('wms_' . $key, 1,"EX",5,"NX");
        if(!$result){
            throw new InvalidRequestException("请勿重复请求,请5秒后再发起请求");
        }
        $response = $next($request);
        Redis::Connection("wms")->del('wms_' . $key);
        return $response;
    }
}

使用：

Route::match(['get', 'post'], '/putawayAction', 'StockShelfController@putawayAction')->middleware('prevent_dup_submit');//上架
    Route::match(['get', 'post'], '/cancelPutawayAction', 'StockShelfController@cancelPutawayAction')->middleware('prevent_dup_submit');//取消上架
    Route::match(['get', 'post'], '/oneKeyPutawayAction', 'StockShelfController@oneKeyPutawayAction')->middleware('prevent_dup_submit');//一键上架
    Route::match(['get', 'post'], '/submitPutawayAction', 'StockShelfController@submitPutawayAction')->middleware('prevent_dup_submit');//提交上架
