将JSON导出到环境变量 [英] Exporting JSON to environment variables

问题描述

如果我有这样的JSON

If I have a JSON like this,

{
    "hello1": "world1",
    "testk": "testv"
}

我想将每个键-值对导出为环境变量，如何通过shell脚本来实现?因此，例如，当我在终端上书写时，应该打印echo $hello1，world1，并且对于其他键值对也应类似地打印? 注意:上面的JSON存在于名为$values的变量中，而不存在于文件中.

And I want to export each of these key-value pairs as environment variables, how to do it via shell script? So for example, when I write on the terminal, echo $hello1, world1 should be printed and similarly for other key-value pairs? Note: The above JSON is present in a variable called $values and not in a file.

我知道这将通过jq完成，并为此编写了一个shell脚本，但这是行不通的.

I know it will be done via jq and written a shell script for this, but it doesn't work.

for row in $(echo "${values}" | jq -r '.[]'); do
    -jq() {
        echo ${row} | jq -r ${1}
    }
    echo $(_jq '.samplekey')
done

尝试Turn的答案，我做到了:

Trying Turn's answer, I did this:

values='{"hello1":"world1","hello1.world1.abc1":"hello2.world2.abc2","testk":"testv"}'
for s in $(echo $values | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" ); do
    export $s
done

推荐答案

从

Borrowing from this answer which does all of the hard work of turning the JSON into key=value pairs, you could get these into the environment by looping over the jq output and exporting them:

for s in $(echo $values | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" ); do
    export $s
done
