# WebToApp
一个基于 WPF 和 WebView2 的网页转桌面应用工具，可以将在线网页或本地网页打包成 Windows 桌面应用程序。
## 功能特性
- 🌐 **支持在线网页**：直接加载远程网页地址
- 📁 **支持本地网页**：支持本地 HTML 文件，可通过 HTTP 服务器或直接文件方式加载
- 🎨 **自定义窗口设置**：可配置窗口大小、置顶、全屏等属性
- 🖱️ **自定义右键菜单**：提供返回、刷新、关于等快捷操作
- 📥 **下载拦截**：智能拦截下载链接，使用系统保存对话框
- 🎯 **滚动条隐藏**：可隐藏网页滚动条，提供更沉浸的体验
- 🖼️ **自定义图标和标题**：支持自定义应用图标和窗口标题
## 技术栈
- **.NET 8.0** - 跨平台开发框架
- **WPF** - Windows Presentation Foundation
- **WebView2** - 基于 Chromium 的 WebView 控件
## 系统要求
- Windows 10/11
- .NET 8.0 Runtime（如果使用独立部署则不需要）
- WebView2 Runtime（通常已预装或会自动下载）
## 快速开始
### 1. 克隆项目
```bash
git clone https://github.com/yourusername/WebToApp.git
cd WebToApp
```
### 2. 配置应用
编辑 `config/config.json` 文件来配置你的应用：
#### 在线网页配置示例
```json
{
"软件名称": "我的应用",
"软件logo": "config/logo.png",
"网页类型": "在线网页",
"在线网页": {
"链接地址": "https://example.com"
},
"注入设置": {
"隐藏网页滚动条": true,
"自定义右键菜单": true,
"拦截下载链接": true
},
"窗口设置": {
"窗口宽度": 1200,
"窗口高度": 800,
"窗口可调整大小": true,
"窗口置顶": false,
"窗口阴影": true,
"全屏": false
}
}
```
#### 本地网页配置示例
```json
{
"软件名称": "我的应用",
"软件logo": "config/logo.png",
"网页类型": "本地网页",
"本地网页": {
"网页目录": "config/web",
"网页入口": "index.html",
"展示模式": "http服务器"
},
"注入设置": {
"隐藏网页滚动条": true,
"自定义右键菜单": true,
"拦截下载链接": true
},
"窗口设置": {
"窗口宽度": 1200,
"窗口高度": 800,
"窗口可调整大小": true,
"窗口置顶": false,
"窗口阴影": true,
"全屏": false
}
}
```
### 3. 构建项目
使用 Visual Studio 或命令行构建：
```bash
dotnet build
```
### 4. 运行应用
```bash
dotnet run
```
或者直接运行编译后的可执行文件。
### 5. 发布应用
发布为独立可执行文件：
```bash
dotnet publish -c Release -r win-x64 --self-contained true
```
发布后的文件在 `bin/Release/net8.0-windows/win-x64/publish/` 目录下。
## 配置说明
### 窗口设置
- `窗口宽度` / `窗口高度`：设置窗口的初始大小（像素）
- `窗口可调整大小`：是否允许用户调整窗口大小
- `窗口置顶`：窗口是否始终显示在其他窗口之上
- `窗口阴影`：是否显示窗口阴影效果
- `全屏`：是否以全屏模式启动
### 注入设置
- `隐藏网页滚动条`：隐藏网页内的滚动条
- `自定义右键菜单`：启用自定义右键菜单（包含返回、刷新、关于等功能）
- `拦截下载链接`：拦截网页中的下载链接，使用系统保存对话框
### 本地网页展示模式
- `http服务器`：使用内置 HTTP 服务器提供网页服务（推荐）
- `直接本地`：直接使用 `file://` 协议加载本地文件
