你们一般是怎么解决大文件上传问题的呢

阿里云本身有node.js前端分片上传的。在阿里云oss配置好对应的id和key,还有其他配置
然后安全起见一般用sts(上传的临时凭证)
后台代码demo

<?php
namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use AlibabaCloud\Client\AlibabaCloud;
use AlibabaCloud\Client\Exception\ClientException;
use AlibabaCloud\Client\Exception\ServerException;


class BigToYunController extends Controller
{

    protected  $appid = '';
    protected  $secret = '';
    protected  $region = '';
    protected  $bucket = '';
    protected  $endpoint = '';

    public function __construct(){
        //这里还可以限制域名和ip  todo
        $this->appid = 'LTAI4333333'; //子账号的
        $this->secret = 't4Ig5f5666666'; //子账号的
        $this->region = config('aliyun.oss.region');
        $this->bucket = config('aliyun.oss.bucket');
        $this->endpoint = config('aliyun.oss.endpoint');

    }

    //返回sts 临时上传配置
    public function sts(){
        //构建一个阿里云客户端，用于发起请求。
        //构建阿里云客户端时需要设置AccessKey ID和AccessKey Secret。
        AlibabaCloud::accessKeyClient($this->appid, $this->secret)
            ->regionId($this->region)
            ->asDefaultClient();

        //设置参数，发起请求。
        try
        {
            $result = AlibabaCloud::rpc()
                ->product('Sts')
                ->scheme('https') // https | http

                        ]
                )
                ->request();
            $res = $result->toArray();

            //$sts = \Arr::get($res,'Credentials');
            //$sts = array_push($sts,['']); //todo



            return $this->success('文件上传临时配置',$res);
            //dd($result->toArray());
        }
        catch
        (ClientException $e) {
