# Device SDK for C++

## 依赖
- libcurl
- nlohmann/json
- OpenSSL

### Windows
1. vcpkg 安装依赖：
```bash
vcpkg install curl:x64-windows
vcpkg install openssl:x64-windows
vcpkg install nlohmann-json:x64-windows
```
### Linux
1. Ubuntu/Debian:
```bash
sudo apt-get install libcurl4-openssl-dev libssl-dev nlohmann-json-dev
```
2. CentOS/RHEL:
```bash
sudo yum install libcurl-devel openssl-devel nlohmann-json-devel
```

## 编译
### Windows (Visual Studio)
1. 添加包含目录：
   - $(vcpkg_root)/installed/x64-windows/include
2. 添加库目录：
   - $(vcpkg_root)/installed/x64-windows/lib
3. 添加依赖库：
   - libcurl
   - libssl
   - libcrypto

### Linux

```bash
g++ -o example example.cpp device_sdk.cpp -lcurl -lssl -lcrypto -I/usr/include/nlohmann
```

## 基本用法
### 初始化

```cpp
#include "device_sdk.h"
DeviceClient client("http://localhost:8080", "your-32-byte-encrypt-key-here123456");
```
### 设备注册
```cpp
// 不带授权码注册
DeviceInfo device;
device.uid = "device-001";
device.device_model = "test-model";
std::string error;
if (!client.registerDevice(device, error)) {
std::cerr << "注册失败: " << error << std::endl;
return;
}
// 带授权码注册
DeviceInfo deviceWithLicense;
deviceWithLicense.uid = "device-002";
deviceWithLicense.device_model = "test-model";
deviceWithLicense.license_code = "your-license-code";
if (!client.registerDevice(deviceWithLicense, error)) {
std::cerr << "注册失败: " << error << std::endl;
return;
}
```
### 设备验证
```cpp
ValidateResponse response;
std::string error;
if (!client.validateDevice("device-001", response, error)) {
std::cerr << "验证失败: " << error << std::endl;
return;
}
std::cout << "设备状态: " << response.status << std::endl;
std::cout << "授权类型: " << response.license_type << std::endl;
std::cout << "过期时间: " << response.expire_time << std::endl;
```

### 更新启动次数

```cpp
int count;
std::string error;
if (!client.updateStartCount("device-001", count, error)) {
std::cerr << "更新失败: " << error << std::endl;
return;
}
std::cout << "当前启动次数: " << count << std::endl;
```
### 绑定授权码
```cpp
std::string error;
if (!client.bindLicense("device-001", "license-code-123", error)) {
std::cerr << "绑定失败: " << error << std::endl;
return;
}
```
## 完整示例
```cpp
#include <iostream>
#include "device_sdk.h"
int main() {
try {
DeviceClient client("http://localhost:8080", "your-32-byte-encrypt-key-here123456");
std::string error;
// 注册设备
DeviceInfo device;
device.uid = "device-001";
device.device_model = "test-model";
if (!client.registerDevice(device, error)) {
std::cerr << "注册失败: " << error << std::endl;
return 1;
}
std::cout << "设备注册成功" << std::endl;
// 绑定授权码
if (!client.bindLicense("device-001", "license-code-123", error)) {
std::cerr << "绑定失败: " << error << std::endl;
return 1;
}
std::cout << "授权码绑定成功" << std::endl;
// 验证设备
ValidateResponse response;
if (!client.validateDevice("device-001", response, error)) {
std::cerr << "验证失败: " << error << std::endl;
return 1;
}
std::cout << "设备状态: " << response.status << std::endl;
std::cout << "授权类型: " << response.license_type << std::endl;
// 更新启动次数
int count;
if (!client.updateStartCount("device-001", count, error)) {
std::cerr << "更新失败: " << error << std::endl;
return 1;
}
std::cout << "当前启动次数: " << count << std::endl;
} catch (const std::exception& e) {
std::cerr << "发生错误: " << e.what() << std::endl;
return 1;
}
return 0;
}
