使用jq转换数组中的authorizedKey字段
使用jq转换数组中的authorizedKey字段
提问于 2019-02-26 06:39:25
给定以下结构：
[
{
"authorizedKey": "0",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "aaa12345-1234-1234-1234-1234567890ab"
},
{
"authorizedKey": "1",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "bbb12345-1234-1234-1234-1234567890ab"
},
{
"authorizedKey": "1",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "ccc12345-1234-1234-1234-1234567890ab"
}
]如果只使用jq，有没有办法把它转换成下面的结构？或者我需要把它包装在某种外部逻辑中？
[
{
"authorizedKey": "zero",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "aaa12345-1234-1234-1234-1234567890ab"
},
{
"authorizedKey": "one",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "bbb12345-1234-1234-1234-1234567890ab"
},
{
"authorizedKey": "one",
"description": "This key is for system testing.",
"keyExpiration": "2035-02-02T18:28:59Z",
"keyId": "ccc12345-1234-1234-1234-1234567890ab"
}

这是可行的：
map(. + {authorizedKey: {"0": "zero", "1": "one"}[.authorizedKey]})如果除了0和1之外还有其他值，则可以将它们添加到映射中。如果你有更多，并且你想提高可读性，你可以这样做：
{"0": "zero", "1": "one"} as $mapping |
map(. + {authorizedKey: $mapping[.authorizedKey]})这避免了在代码中间写入值映射。
这是因为+运算符是在jq中的对象上定义的，并且如果RHS中的键已经存在于LHS中，那么它的值将被替换为来自RHS的相应值。
