Note
適用於 .NET 的 Telegram 機器人自託管輔助工具即將推出。
Note
目前尚未提供適用於 Go 的 Telegram 機器人自行託管輔助工具。
agent-framework-hosting-telegram 將 Telegram 機器人 API 更新轉換為代理框架的執行值,並將最終或串流執行以機器人 API 操作形式呈現。 它不提供機器人客戶端、輪詢執行時、webhook 路由器、指令登錄檔或交付框架。
pip install --pre agent-framework agent-framework-foundry agent-framework-hosting agent-framework-hosting-telegram azure-identity
使用任何能提供更新有效載荷並執行輔助器回傳操作的 Telegram 用戶端函式庫。 範例使用 aiogram,但這些輔助函式並未與其綁定。
執行更新
aiogram webhook 範例驗證 Telegram 的秘密標頭,發送更新,並使用機器人範圍的會話 ID 來保留每個私人聊天或共享群組聊天的代理會話。

Important
在處理更新前,請先確認 Telegram webhook 的送達情況。 webhook 秘密用來驗證 Telegram 的傳遞,但不會授權 Telegram 使用者或聊天室存取應用程式資料。 在應用程式套用授權政策之前,將聊天和使用者 ID 視為不信任。
