Question

我有一个变量 diagnosisCodes ，其值如下所示：

echo $diagnosisCodes
{"code":"some code1","codeSet":"some set1","description":"some description1"} {"code":"some code2","codeSet":"some set2","description":"some description2"} {"code":"some code3","codeSet":"some set3","description":"some description3"}

我想使用定界符"} {"分割它们，以便获得3个不同的值，然后将它们存储在数组中（以bash表示）。

我使用以下命令找到了解决方案（由Incrivel Monstro Verde在注释中建议）：

IFS='|' read -r -a array <<< $(echo $string | sed 's/{"code/|"code/g;s/\"}/"/g')

但是，如果我的字符串具有“ codeSet”属性，而该属性在“ code”属性之前，则此解决方案将失败。

Answer 1

您可以使用以下内容：

#!/bin/bash

string='{"code":"some code1","codeSet":"some set1","description":"some description1"} {"code":"some code2","codeSet":"some set2","description":"some description2"} {"code":"some code3","codeSet":"some set3","description":"some descripti

IFS='{' read -r -a array <<< $(echo $string | sed 's/}//g')

echo "${array[1]}"
echo "${array[2]}"
echo "${array[3]}"

Answer 2

尝试一下

#!/bin/bash

string='{"code":"some code1","codeSet":"some set1","description":"some description1"} {"code":"some code2","codeSet":"some set2","description":"some description2"} {"code":"some code3","codeSet":"some set3","description":"some description3"}'
var="${string//\} {/$'|'}" #replace '} {' with '|' , works for one space only between '} {'
IFS='|' read -r -a array <<< $(echo $var | sed 's/{//g;s/}//g')
for i in "${array[@]}"
  do
    echo $i
  done

使用另一个字符串在变量中拆分值并存储在数组中（Bash）
