Question

我有以下格式的JSON：

{
  "@version": "2.7.0",
  "site": {
    "@name": "http://api:9999",
    "@ssl": "false",
    "alerts": [
      {
        "pluginid": "10094",
        "desc": "<p>Base64 encoded data was disclosed by the application/web server<\/p>",
        "instances": [
          {
            "uri": "http://api:9999",
            "method": "POST",
            "evidence": "DxyPP_YQ6qdWA_Kw_ZLgYilIkXCz93Xs1CeJPvg"
          },
          {
            "uri": "http://api:9999",
            "method": "POST",
            "evidence": "eyJuYmYiOjE121lMWF1siSG9tZUFwcCJdfQ"
          }
        ],
        "count": "37"
      }
    ]
  }
}

我想展平内部数组-.site.alerts.instances以获取以下JSON：

{
    "@name": "http://api:9999",
    "@ssl": "false",
    "alerts": [
      {
        "pluginid": "10094",
        "desc": "<p>Base64 encoded data was disclosed by the application/web server<\/p>",
        "uri": "http://api:9999",
        "method": "POST",
        "evidence": "DxyPP_YQ6qdWA_Kw_ZLgYilIkXCz93Xs1CeJPvg",
        "count": "37"
      },
      {
        "pluginid": "10094",
        "desc": "<p>Base64 encoded data was disclosed by the application/web server<\/p>",
        "uri": "http://api:9999",
        "method": "POST",
        "evidence": "eyJuYmYiOjE121lMWF1siSG9tZUFwcCJdfQ",
        "count": "37"
      }
    ]
  }

我能够通过使用以下JQ模式来展平内部JSON数组：

.site.alerts[] as $in | $in.instances[] as $h |  $in | del(.instances) as $in2 |  $h * $in2

这给了我非常接近的结果：

{
  "uri": "http://api:9999",
  "method": "POST",
  "evidence": "DxyPP_YQ6qdWA_Kw_ZLgYilIkXCz93Xs1CeJPvg",
  "pluginid": "10094",
  "desc": "<p>Base64 encoded data was disclosed by the application/web server</p>",
  "count": "37"
}
{
  "uri": "http://api:9999",
  "method": "POST",
  "evidence": "eyJuYmYiOjE121lMWF1siSG9tZUFwcCJdfQ",
  "pluginid": "10094",
  "desc": "<p>Base64 encoded data was disclosed by the application/web server</p>",
  "count": "37"
}

但不是完美的结果。这些对象不在数组中，并且不包含父对象中不属于数组一部分的字段（例如.site.@name）。

您能帮我改善我创建的JQ模式吗？

谢谢！

这是一个非常好的努力。您的想法是正确的，您已经确保.instances[]数组是平坦的，只需根据需要使用该逻辑来重新构造JSON

jq '{ "@name" : .site."@name", 
      "@ssl"  : .site."@ssl", 
      "alerts": [.site.alerts[] as $in | $in.instances[] as $h | $in | del(.instances) as $in2 | $h * $in2 ]}' json

使用JQ
