我有一个复杂的 json 文件，嵌套在第 4 层和第 5 层，我正在尝试使用 jq 获得以下结果。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 should be installed",
  "desc": "Service besclient should be installed",
  "result": "failed"
}

这是一个 json 文件，我是通过运行 inspec 配置文件获得的。真正的目的是将唯一需要的信息提取到一个简单的 json 中，以便我最终可以更新 AWS Redshift 数据库。

这是一个jq过滤器来解决这个问题。请注意，过滤器之间的“管道”是必不可少的。您必须先展平每个父数组，然后再展平它的子数组，否则您将得到它们的笛卡尔积（这非常糟糕）。

jq '.profiles[] 
     | { Name: .name , Controls: .controls[] } 
     | { Name: .Name, Desc: .Controls.desc , Title: .Controls.title , Results: .Controls.results[] } 
     | { Name: .Name, Desc: .Desc , Title: .Title , StartTime: .Results.start_time , RunTime: .Results.run_time , Result: .Results.status }'

为了清楚起见，在代码中添加了换行符

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

一旦你将它展平到这里，我会考虑将它保存为 CSV，因为这样加载到 Redshift 中会更简单一些。

 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：

"\"java\",\"identify java in PATH system\",\"identify java in system\",\"2017-01-20 05:04:47 +0000\",0.000895896,\"passed\""
…etc
