使用jq在json对象中为每个数组元素生成一行输出，该对象还包括json对象中的其他字段

Question

[我正在尝试格式化一些数据，这些数据由包含一些标识信息的json对象以及一个或多个json对象的数组组成，我希望结果是每个数组元素一行数据，其中每一行应包含数组元素中的某些字段和标识信息中的某些字段。

我的示例数据如下：

{
  "eventCreation": {
    "timeStamp": "2020-06-06T15:07:20Z",
    "epoch": 1591456040
  },
  "eventData": {
    "applName": "SampleApp",
    "channelName": "SYSTEM.DEF.SVRCONN",
    "connectionName": "127.0.0.1",
    "channelType": "Svrconn",
    "remoteProduct": "MQJM",
    "remoteVersion": "09010005",
    "activityTrace": [
      {
        "operationId": "Get",
        "operationTime": "11:07:18",
        "qmgrOpDuration": 102,
        "reasonCode": {
          "name": "No Msg Available",
          "value": 2033
        },
        "objectName": "SYSTEM.DEFAULT.LOCAL.QUEUE"
      },
      {
        "operationId": "Cb",
        "operationTime": "11:07:18",
        "qmgrOpDuration": 10,
        "reasonCode": {
          "name": "None",
          "value": 0
        },
        "objectName": "SYSTEM.DEFAULT.LOCAL.QUEUE"
      },
      {
        "operationId": "Cb",
        "operationTime": "11:07:18",
        "qmgrOpDuration": 12,
        "reasonCode": {
          "name": "None",
          "value": 0
        },
        "objectName": "SYSTEM.DEFAULT.LOCAL.QUEUE"
      }
    ]
  }
}

我想得到这样的输出：

"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","11:07:18","Get",102,"SYSTEM.DEFAULT.LOCAL.QUEUE",2033
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","11:07:18","Cb",10,"SYSTEM.DEFAULT.LOCAL.QUEUE",0
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","11:07:18","Cb",12,"SYSTEM.DEFAULT.LOCAL.QUEUE",0

我可以选择数组中的任何一个元素，使其打印3行，但是如果我添加第二个元素，它将打印9行，第三个元素将打印27行，等等。>>

例如：

jq -r '{channelName: .eventData.channelName, channelType: .eventData.channelType, connectionName: .eventData.connectionName, applName: .eventData.applName, remoteProduct: .eventData.remoteProduct, remoteVersion: .eventData.remoteVersion, operationId: .eventData.activityTrace[].operationId}|[.[]]|@csv' TEST.json
将产生此内容：

"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Get"
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb"
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb"
如果我再加上这样的秒：

jq -r '{channelName: .eventData.channelName, channelType: .eventData.channelType, connectionName: .eventData.connectionName, applName: .eventData.applName, remoteProduct: .eventData.remoteProduct, remoteVersion: .eventData.remoteVersion, operationId: .eventData.activityTrace[].operationId, qmgrOpDuration: .eventData.activityTrace[].qmgrOpDuration}|[.[]]|@csv' TEST.json
将产生此内容：

"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Get",102
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Get",10
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Get",12
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",102
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",10
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",12
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",102
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",10
"SYSTEM.DEF.SVRCONN","Svrconn","127.0.0.1","SampleApp","MQJM","09010005","Cb",12
    

我正在尝试格式化一些数据，这些数据由包含一些标识信息的json对象以及一个或多个json对象的数组组成，我希望结果是一行数据...
