feat(copilot): add tool response normalization utility
Add `normalize_tool_response` function to standardize tool output formats for consistent frontend display. The function converts various response types (dict, list, string) into a unified structure with success metrics, detailed data arrays, and metadata. This ensures backward compatibility while providing predictable response formats for UI components.

# GNS3 Copilot Tool Response Format Standard
|
||||
|
||||
## 概述
|
||||
|
||||
本文档定义了 GNS3 Copilot 工具的标准响应格式,确保所有工具返回统一的数据结构,便于前端处理和美化显示。
|
||||
|
||||
## 标准响应格式
|
||||
|
||||
### 顶层结构
|
||||
|
||||
所有工具应返回以下标准格式:
|
||||
|
||||
```python
|
||||
{
|
||||
"success": bool, # 整体操作是否成功
|
||||
"total": int, # 总操作数量
|
||||
"successful": int, # 成功数量
|
||||
"failed": int, # 失败数量
|
||||
"data": list[dict], # 详细结果列表
|
||||
"error": str, # 全局错误信息(可选,操作完全失败时)
|
||||
"metadata": dict # 元数据(可选)
|
||||
}
|
||||
```
|
||||
|
||||
**字段说明**:
|
||||
|
||||
| 字段 | 类型 | 必需 | 说明 |
|
||||
|------|------|------|------|
|
||||
| `success` | `bool` | 是 | 整体操作是否成功(`failed == 0` 时为 `True`) |
|
||||
| `total` | `int` | 是 | 处理的项目总数 |
|
||||
| `successful` | `int` | 是 | 成功的项目数量 |
|
||||
| `failed` | `int` | 是 | 失败的项目数量 |
|
||||
| `data` | `list[dict]` | 是 | 每个项目的详细结果 |
|
||||
| `error` | `str` | 否 | 全局错误消息(当整个操作失败时) |
|
||||
| `metadata` | `dict` | 否 | 元数据(时间戳、执行时间等) |
|
||||
|
||||
### 单个项目格式
|
||||
|
||||
`data` 数组中的每个项目应遵循以下格式:
|
||||
|
||||
```python
|
||||
{
|
||||
"id": str, # 设备/节点/链接 ID
|
||||
"name": str, # 人类可读的名称
|
||||
"status": "success" | "failed", # 项目状态
|
||||
"result": str, # 成功时的结果或输出
|
||||
"error": str # 失败时的错误信息
|
||||
}
|
||||
```
|
||||
|
||||
**字段说明**:
|
||||
|
||||
| 字段 | 类型 | 必需 | 说明 |
|
||||
|------|------|------|------|
|
||||
| `id` | `str` | 是 | 设备/节点/链接的唯一标识符 |
|
||||
| `name` | `str` | 是 | 人类可读的名称 |
|
||||
| `status` | `str` | 是 | `"success"` 或 `"failed"` |
|
||||
| `result` | `str` | 条件 | 状态为 `success` 时的输出 |
|
||||
| `error` | `str` | 条件 | 状态为 `failed` 时的错误信息 |
|
||||
|
||||
## 示例
|
||||
|
||||
### 成功响应示例
|
||||
|
||||
```python
|
||||
# 执行多个设备的显示命令
|
||||
{
|
||||
"success": True,
|
||||
"total": 3,
|
||||
"successful": 2,
|
||||
"failed": 1,
|
||||
"data": [
|
||||
{
|
||||
"id": "R1",
|
||||
"name": "Router1",
|
||||
"status": "success",
|
||||
"result": "Cisco IOS Software...\nRouter1# show version\n..."
|
||||
},
|
||||
{
|
||||
"id": "R2",
|
||||
"name": "Router2",
|
||||
"status": "success",
|
||||
"result": "Cisco IOS Software...\nRouter2# show version\n..."
|
||||
},
|
||||
{
|
||||
"id": "R3",
|
||||
"name": "Router3",
|
||||
"status": "failed",
|
||||
"error": "Connection refused"
|
||||
}
|
||||
],
|
||||
"metadata": {
|
||||
"tool_name": "execute_multiple_device_commands",
|
||||
"execution_time": 5.2
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 完全失败示例
|
||||
|
||||
```python
|
||||
# 整个操作失败(如参数错误)
|
||||
{
|
||||
"success": False,
|
||||
"total": 0,
|
||||
"successful": 0,
|
||||
"failed": 0,
|
||||
"data": [],
|
||||
"error": "Invalid project_id format",
|
||||
"metadata": {
|
||||
"tool_name": "execute_multiple_device_commands"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 单个设备操作示例
|
||||
|
||||
```python
|
||||
# 操作单个设备
|
||||
{
|
||||
"success": True,
|
||||
"total": 1,
|
||||
"successful": 1,
|
||||
"failed": 0,
|
||||
"data": [
|
||||
{
|
||||
"id": "PC1",
|
||||
"name": "VPCS-1",
|
||||
"status": "success",
|
||||
"result": "IP configuration updated: 192.168.1.10/24"
|
||||
}
|
||||
],
|
||||
"metadata": {}
|
||||
}
|
||||
```
|
||||
|
||||
## 使用标准化函数
|
||||
|
||||
在 `gns3server.agent.gns3_copilot.utils` 模块中提供了 `normalize_tool_response` 函数,用于将各种格式转换为标准格式:
|
||||
|
||||
```python
|
||||
from gns3server.agent.gns3_copilot.utils import normalize_tool_response
|
||||
|
||||
# 标准化工具响应
|
||||
normalized = normalize_tool_response(raw_response, tool_name="my_tool")
|
||||
```
|
||||
|
||||
该函数支持:
|
||||
- 列表格式(`[{...}, {...}]`)
|
||||
- 字典格式(`{"nodes": [...]}`)
|
||||
- 字符串格式(自动解析 JSON/Python literal)
|
||||
- 混合格式(兼容旧工具)
|
||||
|
||||
## 兼容性
|
||||
|
||||
### 向后兼容
|
||||
|
||||
`normalize_tool_response` 函数设计为向后兼容,可以处理现有工具的各种格式:
|
||||
|
||||
- `status` / `error` 字段
|
||||
- `output` / `result` 字段
|
||||
- `device_name` / `name` 字段
|
||||
- `total_nodes` / `total` 字段
|
||||
|
||||
### 推荐的迁移策略
|
||||
|
||||
1. **新工具**:直接返回标准格式
|
||||
2. **现有工具**:保持不变,使用 `normalize_tool_response` 标准化
|
||||
3. **前端**:依赖标准格式处理显示
|
||||
|
||||
## 前端集成建议
|
||||
|
||||
### 渲染逻辑
|
||||
|
||||
```javascript
|
||||
function renderToolResponse(response) {
|
||||
if (!response.success) {
|
||||
// 显示全局错误
|
||||
showError(response.error);
|
||||
return;
|
||||
}
|
||||
|
||||
// 显示统计摘要
|
||||
showSummary(response.total, response.successful, response.failed);
|
||||
|
||||
// 渲染每个项目
|
||||
response.data.forEach(item => {
|
||||
if (item.status === 'success') {
|
||||
showSuccess(item.name, item.result);
|
||||
} else {
|
||||
showError(item.name, item.error);
|
||||
}
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 状态图标
|
||||
|
||||
| 状态 | 图标建议 | 颜色 |
|
||||
|------|----------|------|
|
||||
| `success` | ✓ 绿色 | 绿色 |
|
||||
| `failed` | ✗ 红色 | 红色 |
|
||||
| `unknown` | ? 灰色 | 灰色 |
|
||||
|
||||
## 版本控制
|
||||
|
||||
当前标准版本:`v1.0`
|
||||
|
||||
格式变更时,应更新 `metadata.version` 字段,前端据此适配。
