将JSON导出到环境变量

本文介绍了将JSON导出到环境变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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

从此答案，它完成了将JSON转换为key = value对的所有艰苦工作，您可以通过循环jq输出和export添加它们:

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
