Google bigquery 将json数组插入bigQuery时出错

读取数据时出错，错误消息：解析JSON失败：启动新数组时未找到对象。；BeginArray返回false

我已经创建了以下示例json数据。这是json的数组。每个json对象都在新行中

当我只加载一个json对象而不保留在数组中时，它就工作了

JSON正文-

[
  { "item_name": "dfkhjf", "gtin": "123456", "brand": "Om-Publication","category_name": "books", "country_code": "IN", "marktet_place": "india", "price": 2239, "sellerId": 234, "create_time": "2017-07-19T16:00:46.000Z" },
  { "item_name": "toy-gun", "gtin": "1234234445", "brand": "Toy", "category_name": "toy", "country_code": "IN", "marktet_place": "flipMe", "price": 2239, "sellerId": 234, "create_time": "2017-08-19T16:00:46.000Z" },
  { "item_name": "Drone", "gtin": "12342356456", "brand": "Drone-XX", "category_name": "drone", "country_code": "IN", "marktet_place": "drone-maker", "price": 2239, "sellerId": 234, "create_time": "2017-09-19T16:00:46.000Z" }
]

正如的文档中所解释的，JSON数据必须在中，其中每一行都是有效的独立JSON值，因此应该使用（2）而不是（1）：

(一)

(二)

更新：

下面是一个分步指南，以说明其工作原理：

使用我共享的内容创建一个JSON文件（

file.JSON

）（确保删除每行末尾的数组括号

[]

，以及逗号

，

：

$ cat file.json
{ "item_name": "dfkhjf", "gtin": "123456", "brand": "Om-Publication","category_name": "books", "country_code": "IN", "marktet_place": "india", "price": 2239, "sellerId": 234, "create_time": "2017-07-19T16:00:46.000Z" }
{ "item_name": "toy-gun", "gtin": "1234234445", "brand": "Toy", "category_name": "toy", "country_code": "IN", "marktet_place": "flipMe", "price": 2239, "sellerId": 234, "create_time": "2017-08-19T16:00:46.000Z" }
{ "item_name": "Drone", "gtin": "12342356456", "brand": "Drone-XX", "category_name": "drone", "country_code": "IN", "marktet_place": "drone-maker", "price": 2239, "sellerId": 234, "create_time": "2017-09-19T16:00:46.000Z" }

运行如下命令将文件加载到BQ：

$ bq load --autodetect --source_format=NEWLINE_DELIMITED_JSON dataset.table file.json                                   
Upload complete.
Waiting on bqjob_XXXXXXXXXXX ... (1s) Current status: DONE

现在查询该表以检查内容是否正确上载：

$ bq query --use_legacy_sql=false "SELECT * FROM dataset.table"
Waiting on bqjob_r3ef14ac0d0a6c856_000001681819e9fc_1 ... (0s) Current status: DONE

您能解释一下如何执行insert命令并提供一个示例吗？我已将此数据上传到一个文件中，比如GCS bucket中的-mydata.json。然后从google控制台webUI创建表保持模式auto detect true。并从GCS上传此文件。如果您想在BigQuery中获得3行，可以删除[]从你的JSON，它应该会工作，我试过了。它的力量work@jyoti我已经更新了我的答案，显示了使加载工作正常的一步一步的过程。如果您仍然遇到这方面的问题，请尽可能具体地说明您看到的问题/错误。如果json对象具有完全相同的cont，OP的加载工作是否正常工作但是在一行中？我知道一旦它在bq中，你就必须取消它。
