Azure Synapse - 使用 API 请求正文时数据流失败

Question

我使用了“复制数据”活动和以下请求正文：

{
  "query": "query RoomStays($first: Int!, $from: Date!, $to: Date!, $after: String) {\n  room_stays(\n    first: $first,\n    filter: {\n      reservation_from: { ge: $from },\n      reservation_to: { le: $to }\n    },\n    after: $after\n  ) {\n    pageInfo {\n      hasNextPage\n      endCursor\n    }\n    edges {\n      cursor\n      node {\n        check_in\n        check_out\n        gross\n        lodgingsGross\n        additionalSales\n        reservation_from\n        reservation_to\n        category {\n          name\n        }\n        reservation {\n          createdAt\n          bookingChannelCode\n          stayType {\n          \tname\n        \t}\n          client {\n            country\n          }\n          bookingSource {\n            name\n          }\n        }\n      }\n    }\n  }\n}",
  "variables": {
    "after": "null",
    "from": "2000-01-01",
    "to": "2100-01-01",
    "first": 100
  },
  "operationName": "RoomStays"
}

它可以正常工作，没有任何问题。

现在我尝试通过“数据流”活动复制此内容：

我基本上只是把它串起来：

'{"query": "query RoomStays($first: Int!, $from: Date!, $to: Date!, $after: String) {\n  room_stays(\n    first: $first,\n    filter: {\n      reservation_from: { ge: $from },\n      reservation_to: { le: $to }\n    },\n    after: $after\n  ) {\n    pageInfo {\n      hasNextPage\n      endCursor\n    }\n    edges {\n      cursor\n      node {\n        check_in\n        check_out\n        gross\n        lodgingsGross\n        additionalSales\n        reservation_from\n        reservation_to\n        category {\n          name\n        }\n        reservation {\n          createdAt\n          bookingChannelCode\n          stayType {\n          \tname\n        \t}\n          client {\n            country\n          }\n          bookingSource {\n            name\n          }\n        }\n      }\n    }\n  }\n}","variables": {"after": null,"from": "2000-01-01","to": "2025-01-01","first": 10},"operationName": "RoomStays"}'

失败的原因可能是什么？ 我尝试将“格式”从 JSON 更改为 None，但这并没有改变任何内容。 我不明白我在这里做错了什么。有什么帮助吗？

您需要创建一个列，然后进行外部调用。
