基于Workerman的文件服务器Demo示例,可以支持并发上传大文件

Sdioo

基于"workerman/workerman": "^4.0"

文件上传服务器,可以支持并发上传大文件。基于Workerman。

在命令行中运行

php server.php start

向服务器发送文件

php client.php -h 127.0.0.1 -p 2347 -f  file.tar.gz

运行服务器程序

server.php

<?php
require_once __DIR__.'/vendor/autoload.php';

require_once __DIR__.'/classes/WorkermanUploadServer.php';

$svr = new WorkermanUploadServer();
//设置上传文件的存储目录
$svr->setRootPath('/tmp/');
//设置允许上传的文件最大尺寸
$svr->setMaxSize(100000*1024*1024);
$svr->run();

实现类

<?php

use Workerman\Connection\TcpConnection;
