Azure functions 关于HHTPTrigger从CosmosDB检索文档,azure-functions,Azure Functions,我正在尝试执行HTTP触发器azure函数以从CosmosDB检索文档。我试图在URL中传递id值，但无法检索文档。我从docs.microsoft.com获得了此示例代码功能代码： function.json 网址：即使我在cosmosdb数据库中有id值为“3”的文档，函数也无法检索该文档。请指导我修复错误。我认为问题来自您的cosmosdb中的项目仅提供id无法获取指定的项。容器中的同一id中可以存在多个项请看一下我的cosmosdb：这是我的azure功能： init.py:

我正在尝试执行HTTP触发器azure函数以从CosmosDB检索文档。我试图在URL中传递id值，但无法检索文档。我从docs.microsoft.com获得了此示例代码

功能代码： function.json 网址：

即使我在cosmosdb数据库中有id值为“3”的文档，函数也无法检索该文档。请指导我修复错误。

我认为问题来自您的cosmosdb中的项目

仅提供id无法获取指定的项。容器中的同一id中可以存在多个项

请看一下我的cosmosdb：

这是我的azure功能：

init.py:

import logging

import azure.functions as func


def main(req: func.HttpRequest, documents: func.DocumentList) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    if not documents:
        logging.warning("ToDo item not found")
    else:
        logging.info("Found ToDo item")
    return 'OK'

    "FUNCTIONS_WORKER_RUNTIME": "python",
    "MyAccount_COSMOSDB":"AccountEndpoint=https://testbowman.documents.azure.com:443/;AccountKey=xxxxxx;"
  }
}

启动函数后，只能捕获以下类似项：

{
    "id": "1",
    "testbowman": "1"
}

（这是因为我必须在提供id的同时提供分区键的值。在我的例子中，分区键的名称是testbowman。）

实际使用时，不需要将值固定为1，可以通过

{}

指定相应参数的值

你可以看到我可以成功地到达这里：
