流式导入 Big Query 时请求中不存在任何行

Question

我正在尝试使用 tabledata.insert_all

将导入数据流式传输到大查询中

job_data = {
  kind: 'bigquery#tableDataInsertAllRequest',
  rows: [
    { json: { column_name: value} }
  ]
}

response = execute(
  api_method: bigquery.tabledata.insert_all,
  parameters: {
    projectId: config['project_id'],
    datasetId: DATASET_ID,
    tableId: table_id
  },
  body_object: job_data
)

但我总是收到以下错误信息

Google::APIClient::Request Sending API request post https://www.googleapis.com/bigquery/v2/projects/propane-tribute-90023/datasets/development/tables/api_requests_20150414/insertAll {"User-Agent"=>"My Test App/1.0 google-api-ruby-client/0.8.5 Mac OS X/10.9.5\n (gzip)", "Content-Type"=>"application/json", "Accept-Encoding"=>"gzip", "Authorization"=>"Bearer ya29.VgFYvU2nxGDhWiCdS47XRw0J-7GLenRry0Cd3AA2D1RDzMh5gnf-m85I5GeSr9oNW51OuUb9mdwObg", "Cache-Control"=>"no-store"}

有没有人遇到同样的问题并且知道如何解决？

谢谢。

确保为 table 架构中存在的所有列 headers 提供适当的值。提供单独的“json”条目将使用您提供的列数据填充各个行。除非您已经为名为 column_name 和 value 的变量赋值，否则您需要在 json 声明之后的语句中提供这些值。

tabledata.insert_all“行”操作的示例 Ruby 语法如下所示：

body = {
   "rows" =>[ 
      {"json" => { "person_id" => 10, "person_name" => "test"}}, 
      {"json" => { "person_id" => 11, "person_name" => "test2"}} 
   ]
}
