apiHelper 基于 FastAPI 快速搭建 API jyhelper[api]

安装

基础安装

默认包含:pymysql、requests、sqlparse

pip install jyhelper
# 或
python3 -m pip install jyhelper

按需安装扩展

# API 服务(fastapi + uvicorn)
pip install jyhelper[api]

# MongoDB
pip install jyhelper[mongo]

# 安装全部扩展
pip install jyhelper[all]

# 组合安装
pip install jyhelper[api,mongo]

更新

pip install jyhelper -U 只升级 jyhelper 本体 及基础依赖,不会自动更新扩展依赖。 更新时需带上当初安装的 extras:

# 只装了基础包
pip install jyhelper -U

# 装了 API 扩展,更新时要带上 [api]
pip install jyhelper[api] -U

# 装了多个扩展
pip install jyhelper[api,mongo] -U

# 装了全部扩展
pip install jyhelper[all] -U

# 指定 PyPI 源
pip install jyhelper[api] --upgrade -i https://pypi.org/simple
python3 -m pip install jyhelper[api] --upgrade -i https://pypi.org/simple

使用说明

基础工具

from jyhelper import db, timeHelper, common, fileHelper, feishuRobot

dbIns = db(host='', user='root', password='', port=3306, db='')
for row in dbIns.table('table').select():
    print(row)

print(common.explodeList([1, 2, 3], 2))
print(timeHelper.getDate())
fileHelper.read(file_path='')

apiHelper — 快速搭建 API

需先安装:pip install jyhelper[api]

启动后访问:

  • Swagger 文档:http://127.0.0.1:8787/docs
  • ReDoc 文档:http://127.0.0.1:8787/redoc

方式 1:routes 列表(推荐)

from jyhelper import apiHelper

def hello():
    return apiHelper.success(data={"message": "Hello, World!"})

apiHelper(
    port=8787,
    title="My API",
    routes=[
        {
            "method": "GET",
            "path": "/hello",
            "handler": hello,
            "summary": "Hello 示例",
            "auth": None,
        },
    ],
)

运行:

python adminAPI.py

方式 2:装饰器 + 热重载 / 多进程

from jyhelper import apiHelper

helper = apiHelper(port=8787, auto_run=False)
app = helper.app

@helper.route("GET", "/hello", summary="Hello 示例")
def hello():
    return apiHelper.success(data={"message": "Hello, World!"})

@helper.route("POST", "/hello", auth="change-me", summary="Hello POST 示例")
def hello_post():
    return apiHelper.success(data={"message": "Hello, POST!"})

if __name__ == "__main__":
    import uvicorn
    uvicorn.run(
        "adminAPI:app",
        host=helper.host,
        port=helper.port,
        log_config=helper.log_config,
        reload=True,       # 开发热重载
        # workers=4,       # 生产多进程(与 reload 不能同时用)
    )

统一响应格式

# 成功
return apiHelper.success(data={"id": 1})
return apiHelper.success(message="操作成功", data={"id": 1})

# 错误(HTTP 仍为 200,错误体现在 body.code)
return apiHelper.error(message="参数错误", code=1001)

鉴权

auth 为非空字符串时,请求需携带 Header:

Authorization: Bearer <token>
curl http://127.0.0.1:8787/hello
curl -X POST http://127.0.0.1:8787/hello -H "Authorization: Bearer change-me"

后台运行(Linux)

nohup python3 adminAPI.py >> adminAPI.log 2>&1 &

导入方式

所有模块均可从包根导入:

from jyhelper import apiHelper, db, mysql, mongo, timeHelper, common

要求

  • Python >= 3.5
