Python toolkit for corpus generation, utility functions, and Nacos config center
Project description
sololib
一个 Python 工具包,提供 语料生成、通用工具集、Nacos 配置中心 与 HTTP 中间件 四大功能模块。
当前版本号以
pyproject.toml的version字段为单一来源;运行时可通过sololib.__version__读取。
安装
pip install sololib
# 或
uv add sololib
# 可选依赖(图像处理)
pip install sololib[image]
# 可选依赖(Windows 窗口管理)
pip install sololib[win32]
快速开始
1. 语料生成 (sololib.corpus)
基于 30 个变量池(每池 30 值)和 500+ 中英文问题模板,随机生成对话数据。
from sololib import get_random_conversation
# n=1(默认)返回单组对话: [(question, topic), ...]
conv = get_random_conversation()
for q, topic in conv:
print(f"[{topic}] {q}")
# n>1 返回多组对话: [[(question, topic), ...], ...]
convs = get_random_conversation(n=10)
# 批量生成随机问题(无追问)
from sololib import generate_questions
questions = generate_questions(n=5)
# 生成单个问题
from sololib import generate_single_question
single = generate_single_question()
# 查看语料统计
from sololib import get_corpus_stats
stats = get_corpus_stats()
# 估算模板组合数
from sololib import estimate_combinations
total = estimate_combinations()
概率模型:
- 中文概率:10%,追问概率:50%,三轮追问条件概率:40%
- 自动中英文分离(通过 Unicode 范围检测)
2. 通用工具集 (sololib.utils)
# ---- 异步命令执行 ----
from sololib.utils import run_command
result = await run_command("ls -la", timeout=30)
# {"stdout": "...", "stderr": "...", "returncode": 0}
# ---- 重试装饰器(同步/异步自适应;可指定异常白名单)----
from sololib.utils import retry
@retry(max_retries=3, delay=3.0)
def flaky_function():
...
@retry(max_retries=5, delay=1.0, exceptions=(ConnectionError, TimeoutError))
async def async_network_call():
...
# ---- 递归字典合并 ----
from sololib.utils import merge_dicts
merged = merge_dicts({"a": {"x": 1}}, {"a": {"y": 2}})
# {"a": {"x": 1, "y": 2}}
# ---- 异步 HTTP POST ----
from sololib.utils import post_data, UnauthorizedError, HttpRequestError
try:
result = await post_data("https://api.example.com/data", {"key": "value"})
except UnauthorizedError:
... # 401
except HttpRequestError as e:
... # 其他网络/状态码/解析错误
# ---- Pydantic 统一响应模型 ----
from sololib.utils import success, error, result, result_page, ResponseModel
resp = success() # ResponseModel(code=200, message="success")
resp = result({"id": 1}) # ResponseModel(code=200, message="success", data={"id": 1})
resp = error(400, "Bad request")
resp = result_page([{"id": 1}], total=100)
# ---- PyPI 版本检查 ----
from sololib.utils import check_package_update, update_package, get_current_version
current = get_current_version("sololib")
needs_update = check_package_update("sololib", current)
update_package("sololib")
# ---- YAML 配置加载 ----
from sololib.utils import load_config
from dataclasses import dataclass
@dataclass
class AppConfig:
host: str
port: int
config = load_config("app.yaml", AppConfig)
# ---- Loguru 日志(核心依赖)----
from sololib.utils import setup_logger, shutdown_logger, logger
setup_logger(env="dev", log_dir="logs", level="INFO")
logger.info("Hello, world!")
logger.bind(request_id="req-1").info("带上下文的日志")
shutdown_logger() # 服务优雅退出时调用
3. Nacos 配置中心 (sololib.configs)
基于 nacos-sdk-python v3 全异步 gRPC API,对外暴露同步接口,支持配置热更新。
from sololib.configs import NacosConfig, NacosStore
# 初始化配置(连接 Nacos 并自动拉取所有配置)
nacos_config = NacosConfig(
server_addresses="127.0.0.1:9848",
namespace="public",
username="nacos",
password="nacos",
configs=[
NacosConfig.ConfigItem(data_id="app.yaml", group="DEFAULT_GROUP"),
NacosConfig.ConfigItem(data_id="db.yaml", group="DEFAULT_GROUP"),
],
)
store = NacosStore(nacos_config, is_watcher=True)
# 获取合并后的完整配置
config = store.get_config()
# 手动刷新
store.refresh_config()
# 关闭连接
store.close()
单例约定:
NacosStore是进程级单例。第二次以不同nacos_config构造时,新参数会被忽略并打印 warning;要切换配置必须先close()。
4. HTTP 中间件 (sololib.middleware)
基于 Starlette 的纯 ASGI 实现,无 BaseHTTPMiddleware 双重缓冲开销。
from fastapi import FastAPI
from sololib.middleware import RequestLogMiddleware
app = FastAPI()
app.add_middleware(
RequestLogMiddleware,
exclude_paths={"/health", "/metrics"},
exclude_path_prefixes={"/api/internal"},
log_request_body=True,
log_response_body=True,
request_body_max_len=200,
response_body_max_len=200,
)
# 日志格式:
# [->] POST | path=/api/echo | rid=abc123 | ip=1.2.3.4 | body={"key":"val"}
# [<-] POST | path=/api/echo | rid=abc123 | ip=1.2.3.4 | status=200 | elapsed=12.34ms | body={"result":"ok"}
- 2xx →
INFO;4xx →WARNING;5xx →ERROR - 自动收集请求体(
POST/PUT/PATCH/DELETE,RFC 7231 允许 DELETE 带 body) - 自动跳过
text/event-stream/multipart/*/application/octet-stream响应体
版本要求
- Python >= 3.11
