我有一个json对象数组,我想在bash中将其转换为关联数组,并对键稍作改动
{
"Parameters": [
{
"Name": "/path/user_management/api_key",
"Type": "SecureString",
"Value": "1234",
"Version": 1
},
{
"Name": "/path/user_management/api_secret",
"Type": "SecureString",
"Value": "5678",
"Version": 1
}
]
}
我知道我需要使用jq和sed,但是我只是无法完全找到自己想要的东西。需要去除“ / path / user_management /”并将其余的设置为键,并使用“值”作为值。
试图一起找到一个相当干净的衬管命令。我想结束的是一个类似以下内容的bash关联数组:
myArray[api_key]="1234"
myArray[api_secret]="5678"

索要单行代码与索要不可读的代码一样好。如果您想以适当的方式执行此操作,请在while循环中读取jq
命令的输出,并根据需要除去不需要的字符。
#!/usr/bin/env bash
# declare an associative array, the -A defines the array of this type
declare -A _my_Array
# The output of jq is separated by '|' so that we have a valid delimiter
# to read our keys and values. The read command processes one line at a
# time and puts the values in the variables 'key' and 'value'
while IFS='|' read -r key value; do
# Strip out the text until the last occurrence of '/'
strippedKey="${key##*/}"
# Putting the key/value pair in the array
_my_Array["$strippedKey"]="$value"
done< <(jq -r '.Parameters[] | "\(.Name)|\(.Value)"' json)
# Print the array using the '-p' or do one by one
declare -p _my_Array
或者以传统方式打印数组
for key in "${!_my_Array[@]}"; do
printf '%s %s\n' "${key}" "${_my_Array[$key]}"
done
