支持文件下载(只是大文件下载的会有点慢)
有三个文件,分别为server_listen、server_connect、local_connect
其中server_listen部署在服务器,开启一个端口监听来自server_connect客户端发来的请求,以及返回local_connect设备上的数据信息
server_listen、server_connect部署在服务器上,local_connect部署在需要暴漏在公网的计算机设备上
server_listen监听一个websocket服务
server_connect通过前端js连接server_listen所监听的端口
local_connect也连接server_listen所监听的端口
从而致使用户通过server_connect的web界面与local_connect所部署的计算机产生了连接
server_listen核心代码:
<?php
namespace plugin\webman\gateway;
use GatewayWorker\Lib\Gateway;
use think\facade\Cache;
use Workerman\Connection\TcpConnection;
class Events{
public static $initialize_path="D:\\Desktop\\";//初始化路径
public static function onWorkerStart($worker){
TcpConnection::$defaultMaxPackageSize = 2024000000;//2G
}
public static function onConnect($client_id){
}
public static function onWebSocketConnect($client_id, $data){
}
public static function onMessage($client_id, $message){
$message=json_decode($message,true);
$type=$message['type'];
switch ($type){
case "connect":
//来自1、2的消息连接绑定
Gateway::bindUid($client_id,$message['id']);
break;
case "open_path":
//来自1要打开路径的消息
Gateway::sendToUid(2,json_encode(["type"=>"open_path","data"=>$message['data']]));//发送给2
break;
case "return_open_path":
//来自2的路径及文件信息回显
$now_path=$message['data']['now_path'];
Cache::set("now_path",$now_path);
Gateway::sendToUid(1,json_encode(["type"=>"show_path","data"=>$message['data']]));//发送给1
break;
case "back":
//来自1发送的路径后退请求
$now_path=Cache::get("now_path");//获取当前路径
if ($now_path!=Events::$initialize_path){
//当前路径不等于初始化路径时可以退
Gateway::sendToUid(2,json_encode(["type"=>"open_path","data"=>dirname($now_path,1)]));
}
break;
/*
服务器为Linux请使用如下代码,以为Linux与Windows路径不同
case "back":
//来自1发送的路径后退请求
$now_path=Cache::get("now_path");//获取当前路径
$now_path = str_replace('\\','/',$now_path);
$initialize_path=Events::$initialize_path;
$initialize_path=str_replace('\\','/',$initialize_path);
if ($now_path!=$initialize_path){
//当前路径不等于初始化路径时可以退
$go_path=dirname($now_path,1);
$go_path=str_replace('/','\\',$go_path);
Gateway::sendToUid(2,json_encode(["type"=>"open_path","data"=>$go_path]));
}
break;
*/
case "download":
//来自1的下载请求
Gateway::sendToUid(2,json_encode(["type"=>"download","data"=> $message['data']]));//发送给2获取下载资源
break;
case "return_download":
//来自2返回的下载资源base64编码
Gateway::sendToUid(1,json_encode(["type"=>"return_download","data"=>$message['data']]));//发送给1
break;
}
}
public static function onClose($client_id){
}
}
