# SSHClient
|
||||||
|
|
||||||
|
> 基于 **PyQt5 + paramiko** 的 Windows SSH 客户端，支持远程终端、SFTP 文件浏览、CPU/内存/磁盘/网络实时监控，以及 OpenAI 兼容的 **AI Agent**（可调用工具操作远程主机）。
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
## ✨ 功能特性
|
||||||
|
|
||||||
|
| 模块 | 说明 |
|
||||||
|
| --- | --- |
|
||||||
|
| 多主机管理 | 增删改查、密码/私钥双认证、配置导入导出、配置持久化到 `~/.sshclient/` |
|
||||||
|
| 远程终端 | 命令执行 + 输出捕获 + 退出码 + 超时控制 + 常用命令快捷栏 |
|
||||||
|
| SFTP 文件浏览 | 目录树浏览、上传/下载（带进度条）、新建目录、删除、重命名、双击进入 |
|
||||||
|
| 实时监控 | CPU/内存/负载/启动时间/磁盘/网络速率，1-10 秒可调刷新间隔 |
|
||||||
|
| AI Agent | OpenAI 兼容 API（OpenAI / DeepSeek / Moonshot / 通义千问 / Ollama 等），5 个工具自动调用：执行命令、查指标、列文件、读文件、上传 |
|
||||||
|
| 跨平台 | 代码兼容 Windows / macOS / Linux（PyQt5 + paramiko） |
|
||||||
|
|
||||||
|
## 📦 在 Windows 上构建 exe
|
||||||
|
|
||||||
|
**最简单的方式：双击 `build_windows.bat`**
|
||||||
|
|
||||||
|
1. 安装 [Python 3.10+](https://www.python.org/downloads/windows/)（勾选 Add to PATH）
|
||||||
|
2. 把整个项目目录拷到 Windows 电脑
|
||||||
|
3. 双击 `build_windows.bat`，等 2-3 分钟
|
||||||
|
4. 产物：`dist\SSHClient.exe`（单文件，约 50-60 MB，可拷给任何人直接双击运行）
|
||||||
|
|
||||||
|
**手动方式：**
|
||||||
|
|
||||||
|
```bat
|
||||||
|
python -m venv venv
|
||||||
|
venv\Scripts\activate
|
||||||
|
pip install -r requirements.txt
|
||||||
|
pyinstaller build.spec --clean --noconfirm
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🚀 在 Linux/macOS 上开发
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./build.sh # 一键打包当前平台二进制
|
||||||
|
python main.py # 直接开发运行
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🧪 测试
|
||||||
|
|
||||||
|
```bash
|
||||||
|
source venv/bin/activate
|
||||||
|
python test_core.py # 核心模块 smoke test（无网络依赖）
|
||||||
|
python test_ui.py # UI 组件加载测试（offscreen 渲染）
|
||||||
|
python test_e2e.py # 端到端测试（需本机或可访问的 sshd）
|
||||||
|
```
|
||||||
|
|
||||||
|
## 🎮 使用说明
|
||||||
|
|
||||||
|
### 1. 添加主机
|
||||||
|
左侧 **➕ 新增主机**，填主机名/IP、端口、用户名、密码（可选私钥文件）。
|
||||||
|
|
||||||
|
### 2. 连接
|
||||||
|
选中主机 → **🔌 连接**。状态指示器变绿后即可使用。
|
||||||
|
|
||||||
|
### 3. 终端
|
||||||
|
**⌨ 终端** Tab 直接输入命令回车执行。常用命令（pwd / df / free / top / netstat）有快捷按钮。
|
||||||
|
|
||||||
|
### 4. 文件浏览
|
||||||
|
**📁 文件** Tab 双击目录进入，双击文件直接下载。可拖入 / 上传任意文件。
|
||||||
|
|
||||||
|
### 5. 监控
|
||||||
|
**📊 监控** Tab 点击 **开始监控**，指标会按设定间隔刷新。CPU/内存用大字突出，磁盘用进度条，网络显示当前速率。
|
||||||
|
|
||||||
|
### 6. AI Agent
|
||||||
|
1. 先点 **⚙ AI 设置**，选择预设（OpenAI/DeepSeek/Kimi/通义千问/Ollama）或自定义填 API Key
|
||||||
|
2. 回到 **🤖 AI Agent** Tab，用自然语言提问：
|
||||||
|
- "帮我看 CPU 为什么这么高"
|
||||||
|
- "找出 /var/log 下最大的 10 个文件"
|
||||||
|
- "重启 nginx 服务"
|
||||||
|
3. AI 会自动调用工具（执行命令、查指标等）并给出结论
|
||||||
|
|
||||||
|
> **安全提示**：AI Agent 可以执行任意命令，请使用只读权限的 API Key，或在 prompt 中限定危险操作前需确认。

|
| --- | --- |
|
||||||
|
| `python` 不识别 | 安装 Python 时勾选 "Add Python to PATH" |
|
||||||
|
| 打包失败 `ModuleNotFoundError` | 用 `pip install <module>` 后重新打包 |
|
||||||
|
| exe 启动黑窗闪过 | 已用 `console=False`，如还出现请检查杀毒软件 |
|
||||||
|
| SSH 连接超时 | 检查防火墙、22 端口、目标主机 sshd 是否运行 |
|
||||||
|
| AI 设置测试连接失败 | 检查 API Key 是否正确、Base URL 是否可访问、代理设置 |
