# 设备配置HTTP API使用示例
本文档展示如何通过HTTP API来设置和获取设备参数。
## API端点
基础URL: `http://localhost:5002/api/config`
## 1. 获取所有设备配置
**GET** `/devices`
```bash
curl -X GET http://localhost:5002/api/config/devices
```
**响应示例:**
```json
{
"success": true,
"data": {
"imu": {
"device_type": "real",
"port": "COM6",
"baudrate": 9600,
"timeout": 1.0,
"calibration_samples": 100
},
"pressure": {
"device_type": "real",
"port": "COM5",
"baudrate": 115200,
"timeout": 1.0,
"calibration_samples": 50
},
"camera": {
"device_index": 1,
"width": 1280,
"height": 720,
"fps": 30,
"buffer_size": 1,
"fourcc": "MJPG"
},
"femtobolt": {
"color_resolution": "1080P",
"depth_mode": "NFOV_UNBINNED",
"fps": 30,
"depth_range_min": 1200,
"depth_range_max": 1500,
"synchronized_images_only": false
}
}
}
```
## 2. 获取单个设备配置
**GET** `/devices/{device_name}`
支持的设备名称: `imu`, `pressure`, `camera`, `femtobolt`
```bash
curl -X GET http://localhost:5002/api/config/devices/imu
```
## 3. 设置IMU配置
**POST** `/devices/imu`
```bash
curl -X POST http://localhost:5002/api/config/devices/imu \
-H "Content-Type: application/json" \
-d '{
"device_type": "real",
"port": "COM6",
"baudrate": 9600
}'
```
**请求参数:**
- `device_type`: 设备类型 ("real" 或 "mock")
- `port`: 串口号 (如 "COM6")
- `baudrate`: 波特率 (如 9600)
**响应示例:**
```json
{
"success": true,
"message": "IMU配置更新成功",
"config": {
"device_type": "real",
"port": "COM6",
"baudrate": 9600,
"timeout": 1.0,
"calibration_samples": 100
}
}
```
## 4. 设置压力板配置
**POST** `/devices/pressure`
```bash
curl -X POST http://localhost:5002/api/config/devices/pressure \
-H "Content-Type: application/json" \
-d '{
"device_type": "real",
"use_mock": false,
"port": "COM5",
"baudrate": 115200
}'
```
**请求参数:**
- `device_type`: 设备类型 ("real" 或 "mock")
- `use_mock`: 是否使用模拟数据 (true 或 false)
- `port`: 串口号 (如 "COM5")
- `baudrate`: 波特率 (如 115200)
## 5. 设置相机配置
**POST** `/devices/camera`
```bash
curl -X POST http://localhost:5002/api/config/devices/camera \
-H "Content-Type: application/json" \
-d '{
"device_index": 1,
"width": 1280,
"height": 720,
"fps": 30
}'
```
**请求参数:**
- `device_index`: 相机设备索引 (如 1)
- `width`: 图像宽度 (如 1280)
- `height`: 图像高度 (如 720)
- `fps`: 帧率 (如 30)
## 6. 设置FemtoBolt配置
**POST** `/devices/femtobolt`
```bash
curl -X POST http://localhost:5002/api/config/devices/femtobolt \
-H "Content-Type: application/json" \
-d '{
"color_resolution": "1080P",
"depth_mode": "NFOV_UNBINNED",
"fps": 30,
"depth_range_min": 1200,
"depth_range_max": 1500
}'
```
**请求参数:**
- `color_resolution`: 颜色分辨率 (如 "1080P")
- `depth_mode`: 深度模式 (如 "NFOV_UNBINNED")
- `fps`: 帧率 (如 30)
- `depth_range_min`: 最小深度范围 (如 1200)
- `depth_range_max`: 最大深度范围 (如 1500)
## 7. 重新加载配置
**POST** `/reload`
```bash
curl -X POST http://localhost:5002/api/config/reload
```
## 8. 验证配置
**GET** `/validate`
```bash
curl -X GET http://localhost:5002/api/config/validate
```
**响应示例:**
```json
{
"success": true,
"data": {
"errors": [],
"warnings": [],
"valid": true
}
}
```
## 错误处理
当请求失败时，API会返回错误信息:
```json
{
"success": false,
"message": "错误描述"
}
```
常见的HTTP状态码:
- `200`: 成功
- `400`: 请求参数错误
- `500`: 服务器内部错误
## 启动配置API服务
```bash
# 进入设备目录
cd backend/devices
# 运行配置API服务
python config_api.py
```
服务将在 `http://localhost:5002` 启动。
## Python客户端示例
```python
import requests
import json
# 设置IMU配置
def set_imu_config():
url = "http://localhost:5002/api/config/devices/imu"
data = {
"device_type": "real",
"port": "COM6",
"baudrate": 9600
}
response = requests.post(url, json=data)
result = response.json()
if result['success']:
print("IMU配置设置成功")
print(json.dumps(result['config'], indent=2))
else:
print(f"设置失败: {result['message']}")
# 获取所有设备配置
def get_all_configs():
url = "http://localhost:5002/api/config/devices"
response = requests.get(url)
result = response.json()
if result['success']:
print("所有设备配置:")
print(json.dumps(result['data'], indent=2))
else:
print(f"获取失败: {result['message']}")
if __name__ == "__main__":
set_imu_config()
get_all_configs()
```
