使用jq将json转换为csv，数组嵌套在数组中

如何使用jq将这个json数组展平并写入csv文件，使每一行包含所有字段，即

我对jq有点不熟悉，但从这个开始，它没有捕获内部嵌套数组

jq-r'（[0]|键未排序）作为$keys |$keys，映射（[[.$keys[]]）[]'

[
   {
      "name":"PM2.5",
      "unit":"ug/m3",
      "values":[
         {
            "timestamp":"2020-11-16T13:10:21.135Z",
            "value":3.696
         },
         {
            "timestamp":"2020-11-16T13:10:31.649Z",
            "value":3.696
         },
         {
            "timestamp":"2020-11-16T13:10:42.35Z",
            "value":3.696
         },
         {
            "timestamp":"2020-11-16T13:10:52.953Z",
            "value":3.696
         }
      ]
   },
   {
      "name":"PM10",
      "unit":"ug/m3",
      "values":[
         {
            "timestamp":"2020-11-16T13:10:21.135Z",
            "value":7.596
         },
         {
            "timestamp":"2020-11-16T13:10:31.649Z",
            "value":7.596
         },
         {
            "timestamp":"2020-11-16T13:10:42.35Z",
            "value":7.596
         },
         {
            "timestamp":"2020-11-16T13:10:52.953Z",
            "value":7.596
         }
      ]
   }
]

按如下方式发送到csv：

"name", "unit", "timestamp", "value"
"PM2.5", "ug/m3", "2020-11-16T13:10:21.135Z", 3.696
"PM2.5", "ug/m3", "2020-11-16T13:10:31.649Z", 3.696
"PM2.5", "ug/m3", "2020-11-16T13:10:42.35Z", 3.696
"PM2.5", "ug/m3", "2020-11-16T13:10:52.953Z", 3.696  
"PM10", "ug/m3", "2020-11-16T13:10:21.135Z", 7.596
"PM10", "ug/m3", "2020-11-16T13:10:31.649Z", 7.596
"PM10", "ug/m3", "2020-11-16T13:10:42.35Z", 7.596
"PM10", "ug/m3", "2020-11-16T13:10:52.953Z", 7.596

$jq-r'
[[“名称”、“单位”、“时间戳”、“值”]]，
[ .[] 
|[.名称，.单位]+
（.values[]|[.timestamp，.value]）]
| .[] 
|@csv'input.json

构建一个数组数组，每行一个，包括一个标题行，然后将它们全部格式化为CSV记录。

@Shawn yes抱歉试图添加，但由于堆栈溢出而被标记为

，我添加了一个示例now@Shawn是的，你是对的，下面是一个最简单的例子。由于没有我想要的输出格式，我改进了这个问题。这个问题可以简化（并且更有效），因为不需要最后的。[]，如下：
'[“名称”，“单位”，“时间戳”，“值”]，（[]|[.name，.unit]+（.value[]|[.timestamp，.value]）@csv'
