示例代码

import logging
import azure.functions as func
import pandas as pd
def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
             status_code=200
        )

requirements.txt中提到了pandas lib

当代码部署到函数应用程序时，它的工作

但是在尝试调试本地中的代码时，它不起作用 - 可以看到 pandas 在 Debug模式下安装，如果 pandas import 被删除，我可以调试代码并使用 postman 触发 http 请求(仅与 pandas 包有关的问题)

我的requirements.txt 文件包含

pandas==2.0.1
numpy
azure-functions
azure-storage-blob
openai[embeddings]
requests

Answer 1

我尝试在我的环境中重现相同的情况，但 Pandas 模块出现相同的错误。

可能是因为本地环境中没有正确安装pandas模块。

运行以下命令并检查它是否有助于解决问题。它对我有用:

pip install -r requests.txt。

结果:

然后尝试调试并检查问题是否仍然存在。
