python-2.7 - 提取时自动日期范围

Question

我正在使用以下脚本从Google Analytics（分析）提取数据。在这里，我正在提取上一周的数据。我想自动化日期范围，这样我就不必每周更改date_range了。
我也想避免GA采样数据。请指导我正确执行详细信息的正确方法。

Answer 1

就日期而言，Core Reporting API支持一些有趣的事情。


所有Google Analytics（分析）数据请求都必须指定一个日期范围。如果请求中未包含开始日期和结束日期参数，则服务器将返回错误。使用YYYY-MM-DD模式可以将日期值指定为特定日期，而使用今天，昨天或NdaysAgo模式则可以将日期值指定为相对日期。值必须匹配[0-9] {4}-[0-9] {2}-[0-9] {2} |今天|昨天| [0-9] +（daysAgo）。


所以做类似的事情

start_date = '7daysAgo' 
end_date   = 'today'

请记住，数据没有在24-48小时内完成处理，因此您今天，昨天和前一天的数据可能不是100％准确的。
