python - 发布Azure函数(模型v2)不设置触发器(函数)？

Question

尝试搜索 Google/Bing 聊天/Stack，但没有找到解决我的问题的方法。

我有以下环境:

IDE:PyCharm，CLI:microsoft az/func(运行良好)。定义为本地 func init 。在 azure 函数中创建了该函数。 local.settings.json中的设置与网上的设置相同。应用程序中的文件当前已发布。整个项目的 venv 是相同的，但我在文件夹中放置了一个单独的requirements.txt。

该函数在本地运行良好，func start

但是发布的函数带有 <function folder>\func azure functionapp publish ...没有触发器/功能。

我的功能是这样的:

import azure.functions as func
import logging

from py_pdf import PdfOcrReader

app = func.FunctionApp(http_auth_level=func.AuthLevel.ANONYMOUS)


@app.function_name(name="healthcheck")
@app.route(route="healthcheck")
def healthcheck(req: func.HttpRequest) -> func.HttpResponse:
    return func.HttpResponse("Status OK", status_code=200)


@app.function_name(name="pypdf")
@app.route(route="pypdf")
def pypdf_api(req: func.HttpRequest) -> func.HttpResponse:
    file = req.files.get('file')
    if not file:
        return func.HttpResponse("No file found in the request.", status_code=400)

    # process file
    pdf_obj = PdfOcrReader(file)

    json_out = {
        "pdf_text": pdf_obj.pdf_text,
        "ocr_text": pdf_obj.ocr_computer_vision()
    }
    json_out.update(pdf_obj.metadata)

    return func.HttpResponse(
        str(json_out), status_code=200
    )

host.json 看起来像这样:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

P.S: func publish 时注销看起来像

Answer 1

这可能是因为 WEBSITE_RUN_FROM_PACKAGE 应用设置设置不正确。这指定函数应用是应从包文件运行还是从 wwwroot 目录中的文件运行。

使用下面的 AzCLI 命令更新上述应用设置。

az functionapp config appsettings set --name <functionappname> --resource-group <xxxxRG> --settings WEBSITE_RUN_FROM_PACKAGE=1

您可以查看这个MSDoc有关功能应用设置配置的更多信息。

此问题也可能是由部署包文件引起的。请参阅here从包文件运行函数。

如果问题仍然存在，请尝试创建新的 Python 触发器 Azure 函数并在清除缓存后进行部署。
