前言
1.cpolar简介
cpolar是一款拥有远程控制和内网穿透功能的软件。而且还可以监控端口的HTTP请求，利用实时的cpolar Web UI开发者工具，让您调试代码更容易。您可以监听所有隧道上的HTTP消息包，分析消息包的结构内容，找出问题点。还可以单击重放（Replay）按钮，重新发送该HTTP信令请求。
2.cpolar功能
1、个人使用场景：
- 远程桌面访问公司电脑
- 远程方面家中电脑
- 搭建私人Web站点
2、中小企业远程办公场景：
- 远程桌面（个人或公司使用）
- 远程访问文件共享服务器（中小企业使用）
- 远程访问公司内网财务系统、进销存系统、ERP系统（小中企业使用）
3、游戏玩家使用场景：
- 搭建个人游戏私服
4、群晖NAS（个人网络存储服务器）用户使用
- 远程访问家中的NAS文件服务器Web管理界面
- 远程文件共享服务
- 远程用手机看视频（通过手机或PC远程访问家中的视频文件库，观看小姐姐）
- 为啥要用远程，因为NAS服务器通常也是BT迅雷下载服务器，小姐姐或电影都存在这上面。
5、开发人员使用场景：
- 搭建Web站点，用于测试，用于给客户演示场景
- 联调公网API服务，例如远程调试支付宝接口
- 联调开发微信公众号，小程序接口
- 远程访问数据库
- 搭建私有git源代码仓库
- 搭建私有CI服务器
- 搭建私有SVN源代码服务器
- 远程SSH服务器家中的服务器，或者公司的服务器
- 远程使用vs code编辑代码
6、批量商业使用场景：
- 开发智能终端的用户，希望在他们开发的每个终端上，都安装cpolar，用于可以随时ssh远程访问的能力。例如，初期100台设备上安装（试生产），成功后，再部署到1-4万台设备上。
- 企业用户，希望在公司的每台电脑上，都配置远程桌面功能，访问疫情期间，远程办公方便。
- 有一个店家，有5个店，他是老板，但他并不希望每次都跑过去查看电脑上的财务数据。可以安装cpolar到这5个店的电脑中，他只要在家中，远程访问即可。
- 私有云服务，企业希望打造一套自己的内网穿透系统，独立搭建一套私有云服务。
一、无公网IP异地远程连接内网群晖NAS【内网穿透】
1.1 注册cpolar账号
官网链接：https://i.cpolar.com/m/4VfC
进入cpolar官网，我们先点击右上角的免费注册，使用邮箱注册一个账号，我们后面会需要用到。
1.2 下载cpolar客户端进行内网穿透
下载完一路安装就好了，安装完成进入安装的文件夹执行注册，注册的命令如下：
cpolar authtoken <YOUR_AUTH_TOKEN>
cpolar http 5000执行成功界面如下
访问网址：https://458ed76c.vip.cpolar.cn/swagger/index.html
内网swagger映射成功
1.3 进行钉钉回调事件的监听测试
进入钉钉后台管理注册事件订阅
进行保存后端断点收到钉钉发过来信息，支持内网应用程序和钉钉已经进行互通了
