I working on Ruby on Rails application using a PostgreSQL database. I have heard of the Data Export API for GA. However, after reading through there documentation I am still a little confused about how to export the data.
总之，我的目标是从GA导出摘要数据，turn它进入csv文件，然后将其插入我的数据库。任何方向如何做到这一点将非常感谢。
To summarize, my goal is to export the summary data from GA, turn it into a csv file, and then insert it into my database. Any direction in terms of how to do this would be greatly appreciated.
