查了一下怎麼拿json格式的裡面的特定資料
詳細請參考Ref
e.g.:資料長這樣子:
[
{
...略
"Attributes": {
"ACPI002": true,
...略
},
...略
}
]
curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s '.Attributes' 這樣查詢會錯誤：
因為{}外層有[]，所以一開始要填.[]，而不是.Attributes
curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s '.[]'
只需要"Attributes"的資料
curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s '.[].Attributes'
只需要"Attributes": {...略}底下的特定資料 example: MEMS00F, PMS001, PMS007, PRSS011, MDFX001, IPMINM1, PRSS01C, TER06B, IPMI000
curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s '.[].Attributes | {MEMS00F, PMS001, PMS007, PRSS011, MDFX001, IPMINM1, PRSS01C, TER06B, IPMI000}'
實際範例：透過usb over (BMC)LAN，使用Redfish功能，修改BIOS設定值，改完後重開機，回到OS底下檢查BIOS數值是否生效：
GET URI: /redfish/v1/Systems/Self/Bios 底下的資料
[root@localhost ~]# curl -X GET -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s

譬如，用PATCH改了一些值
[root@localhost ~]# curl -X PATCH -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios/SD -H "If-Match: *" -H "Content-Type: application/json" -d '{"Attributes": {"MEMS00F": "Disabled","PMS001": "Disable","PMS007": "Auto","PRSS011": "Disable","MDFX001": "BIOS Setup","IPMINM1": "Disabled","PRSS01C": "Enable","TER06B": "COM0 (Serial Over Lan)","IPMI000": "Disabled"}}'
[root@localhost ~]#
[root@localhost ~]# curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios/SD
{"@odata.context":"/redfish/v1/$metadata#Bios.Bios","@odata.etag":"\"1682585929\"","@odata.id":"/redfish/v1/Systems/Self/Bios/SD","@odata.type":"#Bios.v1_0_6.Bios","Attributes":{"IPMI000":"Disabled","IPMINM1":"Disabled","MDFX001":"BIOS Setup","MEMS00F":"Disabled","PMS001":"Disable","PMS007":"Auto","PRSS011":"Disable","PRSS01C":"Enable","TER06B":"COM0 (Serial Over Lan)"},"Description":"Future BIOS Settings","Id":"SD","Name":"Future BIOS Settings"}[root@localhost ~]#
[root@localhost ~]#
確認設定進去的值
[root@localhost ~]# curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios/SD | jq -s

},

}
]
[root@localhost ~]#
AMI有bmc usb over lan的BUG，所以檢查兩次確認是不是有問題
[root@localhost ~]# curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios/SD | jq -s
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed

[
{
"@odata.context": "/redfish/v1/$metadata#Bios.Bios",
"@odata.etag": "\"1682585929\"",
"@odata.id": "/redfish/v1/Systems/Self/Bios/SD",
"@odata.type": "#Bios.v1_0_6.Bios",
"Attributes": {

"TER06B": "COM0 (Serial Over Lan)"
},
"Description": "Future BIOS Settings",
"Id": "SD",
"Name": "Future BIOS Settings"
}
]
[root@localhost ~]#
系統重開後，檢查值
[root@localhost ~]# curl -k -u admin:admin https://169.254.0.17/redfish/v1/Systems/Self/Bios | jq -s '.[].Attributes | {MEMS00F, PMS001, PMS007, PRSS011, MDFX001, IPMINM1, PRSS01C, TER06B, IPMI000}'
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 8019 100 8019 0 0 9238 0 --:--:-- --:--:-- --:--:-- 9238
{
"MEMS00F": "Disabled",
"PMS001": "Disable",
"PMS007": "Auto",
"PRSS011": "Disable",
"MDFX001": "BIOS Setup",
"IPMINM1": "Disabled",
"PRSS01C": "Enable",
"TER06B": "COM0 (Serial Over Lan)",
"IPMI000": "Disabled"
}
方便辨識把原先PATCH的內容貼出來看比對
[root@localhost ~]# echo '{"Attributes": {"MEMS00F": "Disabled","PMS001": "Disable","PMS007": "Auto","PRSS011": "Disable","MDFX001": "BIOS Setup","IPMINM1": "Disabled","PRSS01C": "Enable","TER06B": "COM0 (Serial Over Lan)","IPMI000": "Disabled"}}' | jq -s
[
{
"Attributes": {
"MEMS00F": "Disabled",
"PMS001": "Disable",
"PMS007": "Auto",
"PRSS011": "Disable",
"MDFX001": "BIOS Setup",
"IPMINM1": "Disabled",
"PRSS01C": "Enable",
"TER06B": "COM0 (Serial Over Lan)",
"IPMI000": "Disabled"
}
}
]
