基于 WebSocket 的远程控制应用介绍

📘 中文版介绍

概述

基于 WebSocket 的远程控制应用是一种轻量级、高实时性的远程交互方式。它通过持久化的 WebSocket 连接，让客户端与服务端之间能够进行双向通信，从而实现命令执行、鼠标键盘输入模拟以及特殊指令控制等功能。

主要功能

认证机制：客户端连接成功后需立即发送密码进行认证，确保安全性。
命令执行：支持通过 JSON 格式消息发送 CMD 命令，服务端执行后返回结果。
会话管理：客户端可请求新会话，服务端关闭当前连接并允许重新建立。
输入控制：
- 鼠标：支持移动、定位、点击、滚轮等操作。
- 键盘：支持按键按下/释放、文本输入、组合键模拟。
特殊指令：如 Kill_Actived_target（结束当前激活程序）、Block_Input（禁用输入）、Resume_Input（恢复输入）。

应用场景

远程桌面管理与维护
远程执行脚本
安全管控与应急操作

优势

实时性强：WebSocket 提供低延迟的双向通信。
扩展性好：支持多种输入与命令格式。
跨平台：客户端可用多种语言实现（如 Java、Python）。

Android 客户端演示

由开发者提供的 Android 平台的客户端演示，主要功能包括：

登录认证：客户端在连接服务端后完成密码认证，确保安全访问。
远程 CMD 虚拟控制台：支持远程执行命令，并实时接收服务端返回的输出信息。以及一些便捷功能。
远程键鼠控制：
- 完整的触摸板实现，可模拟鼠标移动、点击和滚轮操作。
- 类似笔记本的精简键盘布局，支持常用按键输入与组合键操作。

备注：由于服务端实现为注入虚拟键码，因此在客户端添加新的按键支持时，无需修改服务端逻辑，只需在客户端侧扩展即可。

Overview

A WebSocket-based remote control application provides a lightweight and highly responsive way to interact with remote systems. By establishing a persistent WebSocket connection, the client and server can communicate bidirectionally, enabling command execution, simulated mouse/keyboard input, and predefined special commands.

Key Features

Authentication: Clients must send a password immediately after connection to ensure security.
Command Execution: CMD commands can be sent in JSON format, executed by the server, and results returned.
Session Management: Clients can request new sessions, prompting the server to close the current connection and allow reconnection.
Input Control:
- Mouse: Supports movement, positioning, clicks, and scroll actions.
- Keyboard: Supports key down/up, text input, and shortcut simulation.
Special Commands: Examples include Kill_Actived_target (terminate active program), Block_Input (disable input), and Resume_Input (restore input).

Use Cases

Remote desktop management and maintenance
Script execution remotely
Security control and emergency operations

Advantages

High real-time performance: WebSocket ensures low-latency bidirectional communication.
Flexible and extensible: Supports diverse input and command formats.
Cross-platform: Clients can be implemented in multiple languages (e.g., Java, Python).

Android Client Demonstration

Android client demo provided by developer with the following features:

Login Authentication: The client completes password authentication after connecting to the server to ensure secure access.
Remote CMD Virtual Console: Supports executing commands remotely and receiving real-time output from the server.
Remote Mouse & Keyboard Control:
- A fully functional touchpad implementation for simulating mouse movement, clicks, and scroll actions.
- A simplified laptop-style keyboard layout, supporting common key inputs and shortcut combinations.

Note: Since the server is implemented by injecting virtual key codes, adding new key support requires no server modification. It only needs to be extended on the client side.
