jq ：從子數組中獲取值並顯示在父數組上

我試圖獲得這些價值：

來自此 json 的“VmDisplayName、CreationTimeUTC、EndTimeUTC、原因、結果、狀態、TotalSize、BackupServerReference、BackupJobSessionReference”：

{
 "JobSessionUid": "urn:veeam:BackupJobSession:fe8a7b44-5d5d-4767-e5f4-db0dba854c59",
 "CreationTimeUTC": "2017-11-14T21:02:54Z",
 "EndTimeUTC": "2017-11-14T21:03:30Z",
 "State": "Completed",
 "Result": "Success",
 "Reason": "",
 "TotalSize": 599785472,
 "VmUid": "urn:VMware:Vm:11e45620-a0dc-1278-6d13-11a58ce70564.vm-1128",
 "VmDisplayName": "VMName",
 "Name": "VMName@2017-11-14 21:02:54",
 "UID": "urn:veeam:BackupTaskSession:540c9985-52ab-ab01-a453-e0126edf8716",
 "Links": [
   {
     "Rel": "Up",
     "Href": "https://10.255.147.125:9398/api/backupServers/e435adc7-63f9-4115-be34-0a647e8faa1e",
     "Name": "veeam-dcc-02",
     "Type": "BackupServerReference"
   },
   {
     "Rel": "Up",
     "Href": "https://10.255.147.125:9398/api/backupSessions/fe8a7b44-5d5d-4767-e5f4-db0dba854c59",
     "Name": "Backup Name@2017-11-14 21:00:02",
     "Type": "BackupJobSessionReference"
   },
   {
     "Rel": "Alternate",
     "Href": "https://10.255.147.125:9398/api/backupTaskSessions/540c9985-52ab-ab01-a453-e0126edf8716",
     "Name": "VMName@2017-11-14 21:02:54",
     "Type": "BackupTaskSessionReference"
   },
   {
     "Rel": "Related",
     "Href": "https://10.255.147.125:9398/api/vmRestorePoints/6f27c79f-1d5c-4cf9-b5f8-43143447bc00?format=Entity",
     "Name": "VMName@2017-11-14 21:03:03",
     "Type": "VmRestorePoint"
   }
 ],
 "Href": "https://10.255.147.125:9398/api/backupTaskSessions/540c9985-52ab-ab01-a453-e0126edf8716?format=Entity",
 "Type": "BackupTaskSession"
}

目標是使用 jq 顯示根 json 中的所有元素，如下所示：

{
 "JobSessionUid": "urn:veeam:BackupJobSession:fe8a7b44-5d5d-4767-e5f4-db0dba854c59",
 "CreationTimeUTC": "2017-11-14T21:02:54Z",
 "EndTimeUTC": "2017-11-14T21:03:30Z",
 "State": "Completed",
 "Result": "Success",
 "Reason": "",
 "TotalSize": 599785472,
 "VmUid": "urn:VMware:Vm:11e45620-a0dc-1278-6d13-11a58ce70564.vm-1128",
 "VmDisplayName": "VMName",
 "Name": "VMName@2017-11-14 21:02:54",
 "UID": "urn:veeam:BackupTaskSession:540c9985-52ab-ab01-a453-e0126edf8716",
 "BackupServerReference": "veeam-dcc-02",
 "BackupJobSessionReference": "Backup Name@2017-11-14 21:00:02",
}

我嘗試了幾個命令但沒有成功：

jq '{VmDisplayName,CreationTimeUTC,EndTimeUTC,Reason,Result,State,TotalSize} as $root | (.Links[] | select((.Type == "BackupServerReference")  or (.Type == "BackupJobSessionReference"))) | . as $ref | $root + $ref'

jq '{VmDisplayName,CreationTimeUTC,EndTimeUTC,Reason,Result,State,TotalSize} as $root | (.Links[] | + {"BackupServerReference": select(.Type == "BackupServerReference")})  | . as $ref | $root + $ref'

你能幫助我嗎 ？

最好的祝福，

這個完整的查詢應該產生你想要的輸出：

jq '[del(.Links), (.Links[] | { (.Type): .Name })] | add'

分解：

del(.Links)除了連結之外的所有元素。

(.Links[] | { (.Type): .Name })來自連結中每個子對象的對象，其中包含類型作為鍵和名稱作為值。

[...] | add將所有對象組合在一個數組中，並將它們加在一起作為一個對象。

輸出：

{
 "JobSessionUid": "urn:veeam:BackupJobSession:fe8a7b44-5d5d-4767-e5f4-db0dba854c59",
 "CreationTimeUTC": "2017-11-14T21:02:54Z",
 "EndTimeUTC": "2017-11-14T21:03:30Z",
 "State": "Completed",
 "Result": "Success",
 "Reason": "",
 "TotalSize": 599785472,
 "VmUid": "urn:VMware:Vm:11e45620-a0dc-1278-6d13-11a58ce70564.vm-1128",
 "VmDisplayName": "VMName",

 "Type": "BackupTaskSession",
 "BackupServerReference": "veeam-dcc-02",
 "BackupJobSessionReference": "Backup Name@2017-11-14 21:00:02",
 "BackupTaskSessionReference": "VMName@2017-11-14 21:02:54",
 "VmRestorePoint": "VMName@2017-11-14 21:03:03"
}
