将Python应用程序作为Azure Web应用程序运行

Question

我正在尝试将Microsoft Team BOT作为Azure Web应用程序运行-可以在此处找到完整的代码

application.py：

# Copyright (c) Microsoft Corporation. All rights reserved.
# Licensed under the MIT License.

import sys
import traceback
from datetime import datetime

from aiohttp import web
from aiohttp.abc import HTTPException
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 bots import EchoBot
from config import DefaultConfig

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 = EchoBot()


# 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

在本地运行时，我可以将端口设置为8000，例如，将ngrok指向localhost，并在我的bot通道注册中指定url，一切正常。我一直在努力让我的代码在Azure中工作，但我就是无法做到这一点。我已将脚本配置为在端口8000上运行，并在应用程序设置中设置参数（我尝试了端口和端口，因为我了解到有时其中一个标志不起作用：Azure上的应用程序设置）

但它在日志中仍然说：

站点leobot msbot的容器mycontainer已退出，站点启动失败错误-容器mycontainer未响应端口8000上的HTTP ping，站点启动失败。有关调试，请参阅容器日志。

我也尝试过十几个启动命令，但我就是搞不懂。编辑：找到https://docs.microsoft.com/en-us/azure/app-service/containers/how-to-configure-python并添加了“python3.7-maiohttp.web-hlocalhost-p8000应用程序：init_func”作为启动命令，并将代码更改为

def init_func(argv):
    APP = web.Application(middlewares=[aiohttp_error_middleware])
    APP.router.add_post("/api/messages", messages)
    return APP
if __name__ == "__main__":
    APP = init_func(None)

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

然后在日志上写着-

也许有人有这方面的经验，可以帮助我：）

Answer 1

所以在努力设置我的机器人两天后，我终于找到了答案。借助这篇文章和微软的这篇文章。

在设置-配置下，我添加了启动命令

python3.7 -m aiohttp.web -H 0.0.0.0 -P 8000 application:init_func

重要的是不要使用localhost，而是使用0.0。0.0 !

在我的application.py文件中，我添加了一个init func，如前所述，并将代码更改为

def init_func(argv):
    APP = web.Application(middlewares=[aiohttp_error_middleware])
    APP.router.add_post("/api/messages", messages)
    return APP
if __name__ == "__main__":
    APP = init_func(None)

    try:
        web.run_app(APP, host="0.0.0.0", port=CONFIG.PORT)
    except Exception as error:
        raise error
