Question

所以我已经通过Hello Analytics教程确认OAuth2正在按预期工作，但我对pandas.io.ga模块没有任何好运。特别是，我遇到了这个错误：

In [1]: from pandas.io import ga

In [2]: df = ga.read_ga("pageviews", "pagePath", "2014-07-08")

TypeError: list indices must be integers, not Index

OAuth2按预期工作，我只使用这些参数作为演示变量 - 查询本身就是垃圾。基本上，我无法弄清楚错误的来源，并会欣赏任何可能有的指针。

谢谢！

解决方案（SORT OF）

不确定这是否与我试图访问的数据有什么关系，但是我从pandas.io.ga.GDataReader中的index_col变量中得到了令人讨厌的索引类型错误.get_data（）的类型为pandas.core.index.Index。这被送到_parse_data（）中的pandas.io.parsers._read（）中。我不明白这一点，但这对我来说是一个突破点。

作为修复 - 如果其他人遇到此问题 - 我已将ga.py第270行编辑为：

index_col = _clean_index(list(dimensions), parse_dates).tolist()

现在一切都很顺利，但我怀疑这可能会在其他情况下破坏......

不幸的是，这个模块并没有真正记录，错误并不总是有意义的。包括您的account_name，property_name和profile_name（profile_name是在线版本中的View。然后添加您感兴趣的一些dimensions和metrics。还要确保client_secrets.json位于pandas.io目录中。一个例子：

ga.read_ga(account_name=account_name,
           property_name=property_name,
           profile_name=profile_name,
           dimensions=['date', 'hour', 'minute'],
           metrics=['pageviews'],
           start_date=start_date,
           end_date=end_date,
           index_col=0,
           parse_dates={'datetime': ['date', 'hour', 'minute']},
           date_parser=lambda x: datetime.strptime(x, '%Y%m%d %H %M'),
           max_results=max_results)

pandas.io.ga不适合我
