Question

如何使用Jolt转换进行嵌套/递归转换。在将其输入到后续服务之前，我试图获得所需的输出。

我的输入是

            {
                  "took": 7,
                  "timed_out": false,

                "successful": 1,
                "failed": 0
              },
              "hits": {
                "total": 5,
                "max_score": 1.000438,
                "hits": [

                      "tenant_id": "tenant1",
                      "session_id": "e780ff74-d33e-4024-9bb7-971f067484ea"

                              }
                            },
                            {
                              "_source": {
                                "event_id": 18,
                                "response_time": 1,
                                "url": "http://www.google1.com/"
                              }
                            }
                          ]
                        }
                      }
                    }
                  },
                  {
                    "_id": "BS-SJgvFPkCspwtrqHA1",
                    "_source": {
                      "tenant_id": "tenant2",
                      "session_id": "f4939272-d33e-4024-9bb7-971f067484ea"
                    },
                    "inner_hits": {
                      "network_events": {
                        "hits": {
                          "total": 1,
                          "max_score": 6.0892797,
                          "hits": [
                            {
                              "_source": {
                                "event_id": 18,
                                "response_time": 4,
                                "url": "http://www.google4.com/"
                              }
                            },
                            {
                              "_source": {
                                "event_id": 5,
                                "response_time": 5,
                                "url": "http://www.google5.com/"
                              }
                            }
                          ]
                        }
                      }
                    }
                  }
                ]
              }
            }

所需的输出是

{
   “sessions”: [
      {
            session_id : “S1”,
            tenant_id : “T1”,
            network_events : [
                {
                   “url”: “A”,
                   “response_time” : 22
                },
                {
                   “url”: “B,
                   “response_time” : 1
                }          
           ]


      },
      {
            session_id : “S2”,
            tenant_id : “T1”,
            network_events : [
                {
                   “url”: “C”,
                   “response_time” : 22
                }
           ]


      }
]
}

这是否可以使用Jolt。我尝试了使用示例示例的多个组合，但没有得到太多。

我是Jolt的新手，所以我们将不胜感激。
