javascript - 无法从 CosmosDB 中删除项目

Question

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。

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())
}

我什至尝试将这些值硬编码到代码中(如您所见)，但我总是会收到 404 not found 错误:

我检查了三次:

连接字符串

数据库名称

容器名称

项目 ID

隔断

Answer 1

通过 container.item() 检索文档时，这两个参数是:

文档 ID

分区键

第二个参数(分区键)需要是分区键的值。在您的示例中，您拥有分区键的路径，因此它正在检查“/id”的分区键值:

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')
