问题描述
我正在尝试使用Azure Functions httpTrigger调用从我的数据库中删除一个项目.
I am trying to use an Azure Functions httpTrigger call to delete an item from my database.
import { CosmosClient, } from '@azure/cosmos'
const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
const client = new CosmosClient(process.env.cosmosDB)
const database = client.database('testDB');
const container = database.container('workers');
const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '/id')
console.log(await item.delete())
}
我什至尝试将值硬编码到代码中(如您所见),但我总是会得到404 not found错误:
I even tried to hardcode the values into the code (as you can see) but I will always get 404 not found error:

我三重检查:
- 连接字符串
- 数据库名称
- 容器名称
- item-id
- 分区
推荐答案
通过 container.item()
检索文档时,两个参数是:
When retrieving a document via container.item()
, the two parameters are:
- 文档ID
- 分区键
第二个参数(分区键)必须是分区键的值.在您的示例中,您使用了 path 分区键,因此它正在检查分区键值"/id":
The 2nd parameter (partition key) needs to be the value of the partition key. In your example, you had the path to the partition key instead, so it's checking for a partition key value of "/id":
const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '/id')
这需要更改为:
const item = container.item('28a31558-ff8c-40c3-a7e8-1e8904c5ff72', '<partition-key-value')
