Azure数据工厂-将数据导出到子容器/ blob

Question

嗨，我有一个ADF，可将CSV文件复制（导出Azure SQL数据）到Blob。 如何将文件定向到-“子”容器

我有一个名为“ SQLdata”的Blob，我希望在称为“客户”的子容器/ blob中创建文件

• SQLdata /客户

  SQLdata / Customers / Cust1.csv

  SQLdata / Customers / Cust2.csv

我尝试过

 "destination": {
                            "fileName": "Customers//Cust1.csv"

以下内容有什么问题？

   "activities": [
                    {
                        "name": "Export",
                        "type": "Copy",
                        "dependsOn": [],
                        "policy": {
                            "timeout": "7.00:00:00",
                            "retry": 0,
                            "retryIntervalInSeconds": 30,
                            "secureOutput": false,
                            "secureInput": false
                        },
                        "userProperties": [
                            {
                                "name": "Source",
                                "value": "dbo.@{item().source.table}"
                            },
                            {
                                "name": "Destination",
                                "value": "@{item().destination.fileName}"
                            }
                        ],




 "parameters": {
            "cw_items": {
                "type": "Array",
                "defaultValue": [
                    {
                        "source": {
                            "table": "Cust1"
                        },
                        "destination": {
                            "fileName": "Cust1.csv"
                        }
                    },
                    {
                        "source": {
                            "table": "Cust2"
                        },
                        "destination": {
                            "fileName": "Cust2.csv"
                        }
                    },

我尝试了相同的导出，但是效果很好，所有的csv文件都存储在containerleon/csv中：
