Question

我一直在遵循Google的文档，使用以下代码将数据通过Ruby加载到BigQuery

# project_id      = "Your Google Cloud project ID"
# dataset_id      = "ID of the dataset containing table"
# table_id        = "ID of the table to import file data into"
# local_file_path = "Path to local file to import into BigQuery table"

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new project: project_id
dataset  = bigquery.dataset dataset_id
table    = dataset.table table_id

puts "Importing data from file: #{local_file_path}"
load_job = table.load_job local_file_path

puts "Waiting for load job to complete: #{load_job.job_id}"
load_job.wait_until_done!

puts "Data imported"

一切正常，但是我的CSV文件需要跳过前两行。

我已经通读了更多文档，以了解skip_leading_rows的实例方法，但不确定如何使用它。 https://googleapis.github.io/google-cloud-ruby/docs/google-cloud-bigquery/latest/Google/Cloud/Bigquery/LoadJob.html

对此有一些建议。谢谢！

根据documentation，我希望它能起作用：

puts "Importing data from file: #{local_file_path}"
load_job = table.load_job(local_file_path, skip_leading: 1)

使用Ruby将数据加载到BigQuery时如何跳过开头？
