通过azure函数删除CosmosDB中的文档

阅读 Azure 门户后，我了解了如何制作POST, PUT and GET通过 Azure Functions 与 CosmosDB 进行操作。但是删除，我不明白该怎么做。

我应该使用哪些绑定。它应该通过 sql 查询还是集合的方法（如Remove()）发生？

        [**FunctionName**("EmployeeDocumentDB")]
        public static async Task<HttpResponseMessage> Run(
        [HttpTrigger(AuthorizationLevel.Function, "post", "put", "delete", Route = "EmployeeDocumentDB/partitionkey/{key}/id/{id}")]HttpRequestMessage req,
        [DocumentDB(
        databaseName: "MyDatabase",
        collectionName: "MyCollection",
        ConnectionStringSetting = "CosmosDBEmulator")] ICollector<Person> outputDocument,
        TraceWriter log)
    {
        dynamic data = await req.Content.ReadAsAsync<Person>();

        return req.CreateResponse(HttpStatusCode.Accepted);
    }

我结合：

• HTTP触发器
• Cosmos DB 文档客户端输入
• Cosmos DB 输入以及来自查询字符串的查找 ID

public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "delete")] HttpRequest req,
            [CosmosDB(databaseName: "storage", collectionName: "pizza", Id = "{Query.id}", PartitionKey = "{Query.storeId}", ConnectionStringSetting = "..."] Document document,
            [CosmosDB(databaseName: "storage", collectionName: "pizza", ConnectionStringSetting = ...)] DocumentClient client)
        {
            string storeId = req.Query["storeId"];

            if(document == null || string.IsNullOrEmpty(storeId))
                return new BadRequestResult();

            await client.DeleteDocumentAsync(document.SelfLink, new RequestOptions() { PartitionKey = new PartitionKey(storeId) });

            return new OkResult();
        }
