python - Python 中的 Azure 函数无法使用 pymongo

Question

我有一个在 AKS 中运行的 MongoDB 和一个为将其公开到 AKS 集群之外而创建的负载均衡器。我还使用以下命令在 mongod.conf 中设置了bindIP

sed "s,\\(^[[:blank:]]*bindIp:\\) .*,\\1 0.0.0.0," /etc/mongod.conf
mongod --config C:\mongodb\conf\mongodb.conf

我有一个用 python 编写的 Azure 函数来连接到数据库。

我是 python 新手，只是尝试连接到 mongodb 的基本代码。

import logging

import azure.functions as func
import pymongo


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:
    elif name:
        uri = "mongodb://User:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="efba9c8a9ddfdfdeafdddfc1d7dec1dcdbc1dedfda" rel="noreferrer noopener nofollow">[email protected]</a>:27017/testdb"
        client = pymongo.MongoClient(uri)

        db = client.test
        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
        )

当我尝试运行代码时，出现以下错误，感谢任何帮助。

Answer 1

该错误可能与多种原因相关，如下所述:

1. 如何部署(VSCode、Azure Devops)是部署代码的requirements.txt部分？
2. pymongo 与您的 azure 函数的 python 版本兼容吗？根据此https://pypi.org/project/pymongo/3.9.0/它是兼容的.
3. 该函数已将 WEBSITE_RUN_FROM_PACKAGE 设置为 1？
