BigQuery对导入的JSON数组的支持

Question

我有一个存储在JSON中的项目列表。目前，BigQuery似乎不支持JSON数组。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 
    } 
] 

我收到以下错误：

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

像下面是无效的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 
    } 

那么什么是组项目的最好办法在JSON中可以被BigQuery轻松使用？

Answer 1

我相信输入技术上是无效的JSON。它被称为“换行符分隔的JSON”。每行必须是一个自包含的JSON字典，并在最后加上换行符。线条之间没有逗号。
