我有一个在JSON中获取数据的Bash脚本，我希望能够convert the JSON into an accessible structure数组/列表/或其他模型，这将很容易解析嵌套的数据.
Example:
{
"SALUTATION": "Hello world",
"SOMETHING": "bla bla bla Mr. Freeman"
}
我想得到如下值:echo ${arr[SOMETHING]}
[不同的方法也是可选的.]

If you want key and value, and based on How do i convert a json object to key=value format in JQ, you can do:
$ jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" file
SALUTATION=Hello world
SOMETHING=bla bla bla Mr. Freeman
In a more general way, you can store the values into an array myarray[key] = value like this, just by providing jq to the while with the while ... do; ... done < <(command) syntax:
declare -A myarray
while IFS="=" read -r key value
do
myarray[$key]="$value"
done < <(jq -r 'to_entries|map("(.key)=(.value)")|.[]' file)
And then you can loop through the values like this:
for key in "${!myarray[@]}"
do
echo "$key = ${myarray[$key]}"
done
For this given input, it returns:
SALUTATION = Hello world
SOMETHING = bla bla bla Mr. Freeman
