Amazon redshift 如何使用jq从复杂的JSON文件中获取简单的JSON数据文件
我有一个复杂的json文件,嵌套到第4级和第5级,我正在尝试使用jq获得以下结果。如有任何帮助,将不胜感激:Amazon redshift 如何使用jq从复杂的JSON文件中获取简单的JSON数据文件,amazon-redshift,jq,inspec,Amazon Redshift,Jq,Inspec,我有一个复杂的json文件,嵌套到第4级和第5级,我正在尝试使用jq获得以下结果。如有任何帮助,将不胜感激: { "Name": "unix-global", "Title": "AWS cli should be installed", "desc": "System Package aws-cli should be installed", "result": "passed" } { "Name": "unix-global", "Title": "AWS cli
{
"Name": "unix-global",
"Title": "AWS cli should be installed",
"desc": "System Package aws-cli should be installed",
"result": "passed"
}
{
"Name": "unix-global",
"Title": "AWS cli should be installed",
"desc": "Service besclient should be installed",
"result": "failed"
}
这是一个json文件,是运行inspec配置文件后得到的。真正的目的是将只需要的信息提取到一个简单的json中,以便最终更新AWS红移数据库

这里有一个
jq
过滤器,可以将其平坦化。请注意,过滤器之间的“管道”是必不可少的。必须先展平每个父数组,然后再展平它的子数组,否则将得到它们的笛卡尔积(这非常糟糕)
为清晰起见,代码中添加了换行符
输出:

当你把它夷为平地时,我会考虑把它保存为CSV,这样就可以更简单地加载到红移。
jq '.profiles[]
| { Name: .name , Controls: .controls[] }
| { Name: .Name, Desc: .Controls.desc , Title: .Controls.title , Results: .Controls.results[] }
| [ .Name, .Desc , .Title , .Results.start_time , .Results.run_time , .Results.status ]
| @csv '
输出:
{
"Name": "java",
"Desc": "identify java in PATH system",
"Title": "identify java in system",
"StartTime": "2017-01-20 05:04:47 +0000",
"RunTime": 0.000895896,
"Result": "passed"
}
…etc

你应该a)准确描述简化JSON中应该包含的内容,b)展示你是如何尝试提取它的,以及它是如何失败的,而不是期望有人为你编写代码。@user5188385-请放心,jq是完成任务的最佳选择,因此我建议你学习基础知识,当你有更具体的问题时,根据指南提供一个最小的完整可验证示例,第一个代码块是我期望的结果…名称、标题、描述、复杂json的结果(在第二个代码块中)。请在以下位置使用复杂的json尝试此代码:.profiles[0].name、.profiles[0].controls[].title、.profiles[0].controls[].results[].status非常感谢Joe。这正是我想要的,还有更多。还感谢您在加载到Redshift之前提供的另存为csv的提示。
