# QtRO RPC Demo

这是一个使用 Qt Remote Objects (QtRO) 实现跨进程 RPC 的演示项目。

## 项目结构

└── README.md
```

## 依赖

- CMake >= 3.10
- Qt 5.3+ (需要包含 RemoteObjects 模块)

## 构建步骤

### Windows (MSVC)

```bash
# 1. 创建构建目录
mkdir build
cd build

# 2. 配置 CMake (根据你的 Qt 安装路径修改)
cmake .. -DCMAKE_PREFIX_PATH=C:/Qt/5.3/msvc2013_64

# 3. 编译
cmake --build . --config Release
```

### Windows (MinGW)

```bash
mkdir build
cd build
cmake .. -G "MinGW Makefiles" -DCMAKE_PREFIX_PATH=C:/Qt/5.3/mingw482_32
cmake --build .
```

## 运行

需要打开两个终端:

### 终端 1 - 启动服务端

```bash
cd build
# Windows MSVC
.\Release\rpc_server.exe
# Windows MinGW
.\rpc_server.exe
```

### 终端 2 - 启动客户端

```bash
cd build
# Windows MSVC
.\Release\rpc_client.exe
# Windows MinGW
.\rpc_client.exe
```

## 预期输出

### 服务端输出

```
Server started, listening on tcp://127.0.0.1:5555
MyInterface service is now available for remote calls
Waiting for client connections...
Message set to: "Hello from Client!"
getMessage() called, returning: "Hello from Client!"
add(10, 20) = 30
ping() called - server is alive!
```

### 客户端输出

```
Connected to server successfully!
Remote object acquired successfully!
==========================================

Calling getMessage()...
Server message: "Hello from Server!"

Calling setMessage("Hello from Client!")...

Calling getMessage() again...
Server message now: "Hello from Client!"

Calling add(10, 20)...
Result of add(10, 20) = 30

Calling ping()...

==========================================
All RPC calls completed!
```

## 接口说明

`.rep` 文件定义了远程接口:

| 方法 | 说明 |
|------|------|
| `setMessage(msg)` | 设置消息 (SLOT) |
| `getMessage()` | 获取消息 (SLOT) |
| `add(a, b)` | 加法运算 (SLOT) |
| `ping()` | 心跳测试 (SLOT) |
| `messageChanged(msg)` | 消息变化信号 (SIGNAL) |
| `message` | 消息属性 (PROP) |

## 注意事项

1. 确保防火墙允许 5555 端口通信
2. 必须先启动服务端，再启动客户端
3. Qt 5.3 中 RemoteObjects 为技术预览功能，可能需要手动安装
