BigQuery對導入的JSON數組的支持

Question

我有一個存儲在JSON中的項目列表。目前，BigQuery似乎不支持JSON數組。我有以下的JSON：

[ 
    { 
     "purchaseId": "f7c67e39-5382-4d08-a308-0e4657143c44", 
     "platform": "googleplay", 
     "createdAt": 1364226047214, 
     "type": "currency", 
     "purchaseDate": 1364225968000, 
     "updatedAt": 1364226052634 
    }, 
    { 
     "purchaseId": "f7c67e39-5382-4d08-a308-0e4657143c44", 
     "platform": "googleplay", 
     "createdAt": 1364226047214, 
     "type": "currency", 
     "purchaseDate": 1364225968000, 
     "updatedAt": 1364226052634 
    }, 
    { 
     "purchaseId": "f7c67e39-5382-4d08-a308-0e4657143c44", 
     "platform": "googleplay", 
     "createdAt": 1364226047214, 
     "type": "currency", 
     "purchaseDate": 1364225968000, 
     "updatedAt": 1364226052634 
    } 
] 

我收到以下錯誤：

Line:1/Column:1, Expected '{' found '[' 

像下面是無效的JSON：

{ 
     "purchaseId": "f7c67e39-5382-4d08-a308-0e4657143c44", 
     "platform": "googleplay", 
     "createdAt": 1364226047214, 
     "type": "currency", 
     "purchaseDate": 1364225968000, 
     "updatedAt": 1364226052634 
    }, 
    { 
     "purchaseId": "f7c67e39-5382-4d08-a308-0e4657143c44", 
     "platform": "googleplay", 
     "createdAt": 1364226047214, 
     "type": "currency", 
     "purchaseDate": 1364225968000, 
     "updatedAt": 1364226052634 
    } 

那麼什麼是組項目的最好辦法在JSON中可以被BigQuery輕鬆使用？

Answer 1

我相信輸入技術上是無效的JSON。它被稱爲「換行符分隔的JSON」。每行必須是一個自包含的JSON字典，並在最後加上換行符。線條之間沒有逗號。
