-------------------------------------------------------------------------------- 1 | ## 介绍 2 | 一个简单的web应用程序demo，用作连接到ssh服务器的ssh客户端。它是用go+xterm.js编写的。 3 | 4 | ## 模块 5 | 模块交互图 6 | ![模块交互图](docs/images/webssh.png) 7 | ### 前端ui 8 | 使用xterm.js实现 demo版本只用了简单的html，达到效果就OK 9 | 10 | 前端有个FitAddon插件，在html版本上用了，后面还是用vue+xterm.js实现前端吧。 11 | ### 后端 12 | 从交互图上可以看出，项目有两大功能，一个是ssh交互，一个是回放。在ssh通讯的过程中，交互的数据会被保存下来，这一步要录屏。 13 | #### websocket 14 | 前端ui与ssh服务器通讯的桥梁， 15 | #### terminal 16 | 封装各种shell的控制台。包含本地shell、远程ssh和k8s中pod的shell 17 | #### replay 18 | 包含录屏与回放两种功能。 19 | ## SSH服务器 20 | 本demo提供了这个模拟ssh服务的默认参数，开箱即用。 21 | ```bash 22 | docker run -d -p 222:22 --rm bimg/alpine-ssh 23 | ``` 24 | ssh-server项目地址：https://github.com/basicimage/alpine-ssh 25 | ## 运行 26 | ```bash 27 | go run main.go 28 | ``` 29 | 打开 http://localhost:8080 即可查看效果 30 | ## 效果 31 | ![效果](docs/images/demo.png)
