我正在尝试创建一个简单的 Azure 函数，它接收 HTTP 事件，获取该请求正文中的 JSON 对象，并将该对象保存为 CosmosDB 集合中的文档。然而，我似乎对导入 python 模块很着迷。
__init__.py
import json
import azure.functions as func
import azure.cosmos.cosmos_client as cosmos_client
config = {
'ENDPOINT': 'https://XXXXXX.documents.azure.com:443/',
'PRIMARYKEY': 'XXXXXX',
'DATABASE': 'my-database',
'CONTAINER': 'my-container'
}
def main(req: func.HttpRequest) -> func.HttpResponse:
try:
client = cosmos_client.CosmosClient(config['ENDPOINT'], {'masterKey': config['PRIMARYKEY']})
results = req.get_json()
client.get_database_client(config['DATABASE']).get_container_client(config['CONTAINER']).upsert_item(results)
return func.HttpResponse("Success", status_code=200)
except ValueError:
return func.HttpResponse("Please pass a JSON object", status_code=400)

我尝试过像这个问题建议的那样通过 Kudu为 Azure Function 导入 Python 模块并尝试跑步pip install azure-cosmos但这似乎并不能解决问题。
您需要在 Function App KUDU 中添加 python 扩展。
Step1：安装自定义Python版本
导航到 Kudu 控制台 -https://Your_APP_NAME.scm.azurewebsites.net/DebugConsole在 kudu cli 中运行以下命令将 Python 安装在 D:\home\site\tools 文件夹中
nuget.exe 安装-源https://www.siteextensions.net/api/v2/-输出目录 D:\home\site\tools python352x64
Step2：我们需要有 python.exeD:\home\site\tools Folder。所以让我们移动子文件夹内容（D:\home\site\tools\python352x64.3.5.2.6\content\Python35
) to D:\home\site\tools使用下面的命令
mv /d/home/site/tools/python352x64.3.5.2.6/content/python35/* /d/home/site/tools/
Step3：安装自定义 python 包。
导航到 Kudu 控制台 -https://Your_APP_NAME.scm.azurewebsites.net/DebugConsole运行以下命令在函数应用程序中安装 pandas 模块：
D:\home\site\tools\python.exe -m pip install azure-cosmos
测试示例：
我安装了requests包做一点测试。
D:\home\site\tools\python.exe -m pip install requests
蟒蛇代码：
Output:
