Common utilities and data models for Hezor projects
Project description
Hezor Common
Hezor 项目的公共库,提供数据模型、SDK 客户端、安全工具等通用能力。
Features
- Data Models — Pydantic 数据模型(Creation、Chapter、Section 等)
- DataHub SDK — 智能工具搜索与执行客户端(搜索 → AI 构参 → 执行)
- Hezor2 SDK — 创作报告发布客户端(Webhook)
- Security — Ed25519 签名、JWT 编解码、密钥管理
Installation
pip install hezor-common
DataHub SDK
通过「搜索 → 构建参数 → 执行」三步工作流,调用 DataHub 数据接口。
快速开始
from hezor_common.transfer.datahub_sdk import DatahubSDK
async with DatahubSDK(
base_url="http://10.8.98.9:12580",
api_key="your-api-key",
) as sdk:
# 一步完成:搜索工具 → AI 构建参数 → 执行
result = await sdk.make_call(
query="查询日均实收金额",
context="去年10月,门店编码 S001",
)
print(result.data)
分步调用
async with DatahubSDK(api_key="your-api-key") as sdk:
# 1. 搜索工具
search_resp = await sdk.search_tools(query="查询日均实收", top_k=3)
# 2. AI 构建参数
args = await sdk.build_args(
search_response=search_resp,
args_fill_tips="去年10月,门店 S001",
)
# 3. 执行工具
result = await sdk.execute_tool(
tool_name=search_resp.tools[0].name,
args=args,
)
print(result.success, result.data)
批量调用
async with DatahubSDK(api_key="your-api-key") as sdk:
results = await sdk.make_call_multi(
query="查询品牌信息",
context="获取所有品牌和品类",
top_k=3,
)
for tool_name, result in results.items():
print(f"{tool_name}: {result.data}")
环境变量配置
DATAHUB_API_BASE_URL=http://192.168.0.125:12580
DATAHUB_API_KEY=your-api-key
DATAHUB_LLM_MODEL_ID=gpt-oss-20b
DATAHUB_LLM_API_KEY=your-llm-api-key
DATAHUB_LLM_BASE_URL=http://localhost:8000
详细文档见 docs/datahub_sdk/
Hezor2 SDK
向 Hezor2 服务发布创作报告。
快速开始
from hezor_common.transfer.hezor2_sdk import Hezor2SDK, CreationGenerateResult
async with Hezor2SDK(
base_url="http://localhost:8000",
api_key="your-api-key",
) as sdk:
result = await sdk.publish_creation_report(
creation_result=creation_generate_result,
task_id="monthly_report",
execution_id="exec_2026_03_11_001",
)
print(result.status, result.report_id)
环境变量配置
HEZOR2_API_BASE_URL=http://localhost:8000
HEZOR2_API_KEY=your-api-key
详细文档见 docs/hezor2_sdk/
认证方式
两个 SDK 共享相同的认证机制,支持 API Key 和 MetaInfo JWT 两种方式。
API Key 认证
通过 Authorization: Bearer <api_key> 请求头传递:
async with DatahubSDK(api_key="your-api-key") as sdk:
...
MetaInfo JWT 认证(Ed25519)
通过 X-META-INFO 请求头传递 JWT Token,携带业务元信息并使用 Ed25519 私钥签名:
from hezor_common.transfer.base_sdk import MetaInfo
meta = MetaInfo(
subject="鮨大山",
subject_code="wdyl_001",
caller_id="user_123",
data_coverage="202401-202412",
creation_slug="single_store_profit_model",
creation_name="单店盈利模型",
)
async with DatahubSDK(
api_key="your-api-key",
meta_info=meta,
private_key_path="private_key.pem",
password=b"your_password",
meta_info_expires_in=3600,
) as sdk:
...
两种认证可同时使用,也可单独使用。
Security 模块
提供 Ed25519 密钥管理、消息签名和 JWT 编解码:
from hezor_common.security import (
generate_key_pair,
serialize_private_key,
serialize_public_key,
encode, # JWT 编码 (encode_jwt_with_file)
decode, # JWT 解码 (decode_jwt_with_file)
sign, # JSON 签名 (sign_json_with_file)
verify, # 签名验证 (verify_json_signature_with_file)
)
# 生成密钥对
private_key, public_key = generate_key_pair()
private_pem = serialize_private_key(private_key, password=b"secret")
public_pem = serialize_public_key(public_key)
# JWT 签名与验证
token = encode("private_key.pem", payload={"user": "test"}, password=b"secret", expires_in=3600)
data = decode("public_key.pem", token=token, verify=True)
Data Models
Pydantic 数据模型,用于结构化内容创作:
from hezor_common.data_model import (
CreationModel,
CreationMeta,
Author,
ChapterModel,
SectionModel,
)
author = Author(name="John Doe", avatar="https://example.com/avatar.jpg")
meta = CreationMeta(
name="Single Store Profit Model",
description="A comprehensive profit analysis model",
author=author,
path="food_beverage/single_store_profit_model",
domain="food_beverage",
slug="single_store_profit_model",
)
creation = CreationModel(meta=meta, summary=None, chapters=[])
导出模型:
- Creation:
CreationModel,CreationMeta,CreationSummary,Author,Contributor - Chapter:
ChapterModel,ChapterMeta,ChapterSummary - Section:
SectionModel,TitleGuideline,DataQuery,Dataset,ChartSuggestion,AnalysisGuideline - Results:
SectionGenerateResult,ChapterGenerateResult
Requirements
- Python >= 3.11
- pydantic >= 2.0.0
