我正在尝试使用python标准化来自elasticsearch的json响应。这是一个文档示例：

我感兴趣的只是“ _source”字段的一部分。 我只需要得到这样的输出：
profile.addresses.zipcde|profile.addresses.country|profile.addresses.location....|...salesOpportunities.firstAppointmentDate|salesOpportunities.campaignSources.sourceTimeStamp|
0 40134 ITA BOLOGNA None 2018-06-26T09:12:51.2263824+02:00
1 .... .... .... .... ....
2 .... .... .... .... ....
对于嵌套字段，必须对所有出现的嵌套字段重复父列的值。
我已经读了几天有关该主题的主题，但是我找不到任何适合我的东西（或者也许我无法应用阅读建议）。
可能我必须在循环中使用json_normalize，但是我无法编写正确的代码
请问是否有人可以向我展示逐步实现我的目标的程序。
对不起，我的英语不好。
预先感谢您的回答
