为什么会出现错误“无效算术运算符"? [英] why do I get an error 'invalid arithmetic operator'?

问题描述

我正在尝试将Yaml解析为Json. 并且我想设置具有字符串索引的数组.

I am trying to parse yaml to Json. and I'd like to set the array that has string index.

当我尝试时，出现错误

这是我的出处和错误

keys=$(echo $ci_json | jq 'keys')
key_array=($keys)
ARR=()

for raw_key in ${key_array[@]}; do
        if [ $raw_key = '[' -o $raw_key = ']' ]; then
                continue;
        else
                key=$(echo $raw_key | sed -e 's/"//g' -e 's/,//g')
                value=$(echo $ci_json | jq .$key)$'\t'
                ARR[$key]=$value
        fi
done

错误:localhost.localdomain:语法错误:无效的算术运算符(错误标记为".localdomain")

Error : localhost.localdomain: syntax error: invalid arithmetic operator (error token is ".localdomain")

此错误出现在"ARR [$ key] = $ value"

This error appeared at "ARR[$key]=$value"

有人帮助我吗?

推荐答案

 Error : localhost.localdomain: syntax error: invalid arithmetic operator (error token is ".localdomain")

当ARR是索引数组(非关联数组)且key的值为localhost.localdomain时，这会在ARR[$key]=...上发生. 索引数组应使用数字下标，而不是任意字符串.

This happens on ARR[$key]=... when ARR is an indexed array (not associative) and the value of key is localhost.localdomain. Indexed arrays should use numeric subscripts, not arbitrary strings.

如果要将字符串索引与ARR一起使用， 您必须将其声明为关联数组， 从Bash 4开始受支持:

If you want to use string indexes with ARR, you must declare it as an associative array, which is supported as of Bash 4:

declare -A ARR
