使用 Bot 框架部署 Azure Web 应用程序：解决“无法找到属性‘app’”错误

Question

我已在 Azure Web App 上使用 Bot Framework 部署了 Python 代码库，但遇到错误：“无法在‘app’中找到属性‘app’。”启动应用程序的代码遵循标准的 Microsoft 代码示例。

这是代码片段：

import sys
import traceback
from datetime import datetime
from http import HTTPStatus

from aiohttp import web
from aiohttp.web import Request, Response, json_response
from botbuilder.core import (
    BotFrameworkAdapterSettings,
    TurnContext,
    BotFrameworkAdapter,
)
from botbuilder.core.integration import aiohttp_error_middleware
from botbuilder.schema import Activity, ActivityTypes

from bot import MyBot
from config import DefaultConfig
from openaibot.openaibot import OpenAIBot

CONFIG = DefaultConfig()

# Create adapter.
# See https://aka.ms/about-bot-adapter to learn more about how bots work.
SETTINGS = BotFrameworkAdapterSettings(CONFIG.APP_ID, CONFIG.APP_PASSWORD)
ADAPTER = BotFrameworkAdapter(SETTINGS)


# Catch-all for errors.
async def on_error(context: TurnContext, error: Exception):
    # This check writes out errors to console log .vs. app insights.
    # NOTE: In production environment, you should consider logging this to Azure
    #       application insights.
    print(f"\n [on_turn_error] unhandled error: {error}", file=sys.stderr)
    traceback.print_exc()

    # Send a message to the user
    await context.send_activity("The bot encountered an error or bug.")
    await context.send_activity(
        "To continue to run this bot, please fix the bot source code."
    )
    # Send a trace activity if we're talking to the Bot Framework Emulator
    if context.activity.channel_id == "emulator":
        # Create a trace activity that contains the error object
        trace_activity = Activity(
            label="TurnError",
            name="on_turn_error Trace",
            timestamp=datetime.utcnow(),
            type=ActivityTypes.trace,
            value=f"{error}",
            value_type="https://www.botframework.com/schemas/error",
        )
        # Send a trace activity, which will be displayed in Bot Framework Emulator
        await context.send_activity(trace_activity)


ADAPTER.on_turn_error = on_error

# Create the Bot
#BOT = MyBot()
OAIBOT = OpenAIBot(CONFIG)
BOT = MyBot(OAIBOT)



# Listen for incoming requests on /api/messages
async def messages(req: Request) -> Response:
    # Main bot message handler.
    if "application/json" in req.headers["Content-Type"]:
        body = await req.json()
    else:
        return  Response(status=415) 

    activity = Activity().deserialize(body)
    auth_header = req.headers["Authorization"] if "Authorization" in req.headers else ""

    response = await ADAPTER.process_activity(activity, auth_header, BOT.on_turn)
    if response:
        return json_response(data=response.body, status=response.status)
    return Response(status=201)


#####
APP = web.Application(middlewares=[aiohttp_error_middleware])
APP.router.add_post("/api/messages", messages)

if __name__ == "__main__":
    try:
        web.run_app(APP, host="localhost", port=CONFIG.PORT)
    except Exception as error:
        raise error

该错误似乎与

web.run_app

部分有关。我不确定为什么找不到“app”属性。

对于可能导致此问题的原因有什么见解或建议吗？部署到 Azure Web App 时，是否需要进行不同的特定配置？我非常感谢任何有关解决此问题的帮助或指导。

发布我的评论作为答案对社区来说是一件好事。

成功部署到 Azure Web 应用程序后，您应该在启动命令 > 配置 > 常规设置 > 启动命令 > python3 -m aiohttp.web -H 0.0.0.0 -P 8000 app 中添加以下内容： Azure Web 应用程序中的 init_func 如下所示。
