OpenFeishu

OpenFeishu 是一个飞书开放平台的 Python SDK,提供了飞书开放平台的接口封装,方便开发者使用飞书开放平台的接口。

使用

快速开始

FeishuClient 是一个异步客户端,统一管理应用凭证、令牌的自动获取与缓存,以及带自动重试的 HTTP 传输。推荐通过 async with 使用,以便自动释放底层连接。消息接口以接收者为第一个参数(其 ID 类型会自动推断),消息内容为第二个参数;client.im.send 还会根据内容的形态自动推断消息类型(msg_type)。

import asyncio

from feishu import FeishuClient


async def main():
    async with FeishuClient("cli_xxx", "app_secret") as client:
        await client.im.send("oc_xxx", "hello, world!")


asyncio.run(main())

应用凭证也可以通过环境变量 FEISHU_APP_ID / FEISHU_APP_SECRET 提供,此时可省略构造参数:async with FeishuClient() as client: ...

命名空间

各业务能力按资源划分到不同命名空间下,每个命名空间提供「裸动词」式的 CRUD 方法(如 create / get / update / delete / list)。常用入口:

命名空间 说明
client.im 即时消息:发送、回复、编辑、撤回、转发消息
client.contact.users / client.contact.departments 通讯录:用户与部门
client.bitable.tables 多维表格:数据表、字段与记录
client.calendar.events 日历:日程与参与人
client.approval.instances 审批:审批实例与任务
client.drive.files 云空间:文件的上传、下载、复制与删除

此外还有 client.docx(新版文档)、client.sheets(电子表格)、client.wiki(知识库)、client.board(画板)、client.vc(视频会议)、client.task(任务)、client.oauth(用户身份 OAuth)、client.cards(卡片构建器)等命名空间。

async with FeishuClient("cli_xxx", "app_secret") as client:
    user = await client.contact.users.get("ou_xxx", user_id_type="open_id")
    records = await client.bitable.records.list("app_token", "tbl_xxx")

接收事件

要接收飞书推送的事件(如「接收消息」),先用 EventDispatcher 按事件类型注册异步处理函数,Webhook 接收器与长连接两种接入方式共用同一套处理函数。

from feishu.events import EventDispatcher

dispatcher = EventDispatcher()


@dispatcher.on("im.message.receive_v1")
async def on_message(event):
    print(event.event_id)

方式一:Webhook 接收器。 当应用有公网回调地址时,用 create_event_app 生成一个可独立运行的 Starlette 应用,默认带签名新鲜度(防重放)与去重保护,以任意 ASGI 服务器(如 uvicorn)运行即可:

from feishu.events import create_event_app

app = create_event_app(dispatcher, encrypt_key="ek_secret")
# uvicorn module:app

方式二:长连接(WebSocket)。 当应用没有公网回调地址时,用 feishu.ws.WsClient 主动与飞书建立一条持久 WebSocket 连接(对标 Slack 的 Socket Mode),事件经该连接推送:

import asyncio

from feishu.ws import WsClient

ws = WsClient("cli_xxx", "app_secret", dispatcher)
asyncio.run(ws.start())

长连接依赖可选的 websockets 包,可通过 pip install open-feishu[ws] 安装。
