[英]Bash jq with dynamic name
I'm trying to create a script to read the return code from a json from a curl command.我正在尝试创建一个脚本来从 curl 命令读取 json 的返回码。
my curl command is:我的 curl 命令是:
curl -sk 'https://192.168.0.1/custom/getData.php?device=mydevice&object=http--HTTP_v6_Global Index&indicator=http_httpCode&plugin=xxx' | jq '.'
The json output is: json output 是:
{
"device": "mydevice",
"object": "http--HTTP_v6_Global ",
"object_descr": "HTTP download of http://192.168.0.1",
"indicator": "http_httpCode",
"indicator_descr": null,
"plugin": "xxx",
"starttime": 1650468121,
"endtime": 1650468421,
"data": {
"1650468248": {
"http_httpCode#HTTP Code": 200
}
}
}
How can read the value "http_httpCode#HTTP Code"
if 1650468248
is a dynamic value?如果
1650468248
是动态值,如何读取值"http_httpCode#HTTP Code"
?
You could use to_entries
so you can use .value
to target the 'unknown' key:您可以使用
to_entries
以便您可以使用.value
来定位“未知”键:
jq '.data | to_entries | first | .value."http_httpCode#HTTP Code"'
Another approach by just 'looping over everything' either with..
or .[]
:另一种方法是使用
..
或.[]
来“遍历所有内容”:
jq '.data | .. | ."http_httpCode#HTTP Code"? // empty'
jq '.data | .[]."http_httpCode#HTTP Code"'
They all return 200
他们都返回
200
Thanks I solved.谢谢我解决了。 This is my solution:
这是我的解决方案:
jq -r '.data | .[]."http_httpCode#HTTP Code"'
