我正在尝试使用VSCode在Azure函数上部署一个现有的快速API应用程序。
我得到这个错误：

No HTTP triggers found

我的项目结构：

这就是function.json的内容

{
    "scriptFile": "backend/main.py",
    "bindings": [
      {
        "authLevel": "anonymous",
        "type": "httpTrigger",
        "direction": "in",
        "name": "req",
        "methods": [
          "get",
          "post"
        ],
        "route": "{*route}"
      },
      {
        "type": "http",
        "direction": "out",
        "name": "$return"
      }
    ]
}

Main.py 文件中，我添加了azure函数处理程序。

import logging
import azure.functions as func

from apis.base import api_router
from core.config import settings

from db.base import Base
from db.session import engine
from db.utils import check_db_connected
from db.utils import check_db_disconnected
from fastapi import FastAPI
from fastapi.staticfiles import StaticFiles
from webapps.base import api_router as web_app_router

def include_router(app):
    app.include_router(api_router)
    app.include_router(web_app_router)

def configure_static(app):
    app.mount("/static", StaticFiles(directory="static"), name="static")

def create_tables():
    Base.metadata.create_all(bind=engine)

def start_application():
    app = FastAPI(title=settings.PROJECT_NAME, version=settings.PROJECT_VERSION)
    include_router(app)
    configure_static(app)
    create_tables()
    return app

app = start_application()

async def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')
    await check_db_connected()
    try:
        body = await req.get_body()
        return func.HttpResponse(str(body))
    except Exception as e:
        logging.exception('Error')
        return func.HttpResponse("Error", status_code=500)

    await check_db_disconnected()

我是不是漏掉了什么
我试着部署一个虚拟的API，它是成功的。改变了我的项目中的目录结构，仍然我无法将它部署到azure函数。
