Regex 使用带有动态值的正则表达式搜索字符串的一部分

我有这个字符串：

{"rendererOptions":{"localeStrings":{"renderError":"An error occurred rendering the PivotTable results.","computeError":"An error occurred computing the PivotTable results.","uiRenderError":"An error occurred rendering the PivotTable UI.","selectAll":"Select All","selectNone":"Select None","tooMany":"(too many to list)","filterResults":"Filter values","apply":"Apply","cancel":"Cancel","totals":"Totals","vs":"vs","by":"by"},"rowSubtotalDisplay":{"hideOnExpand":true}},"localeStrings":{"renderError":"An error occurred rendering the PivotTable results.","computeError":"An error occurred computing the PivotTable results.","uiRenderError":"An error occurred rendering the PivotTable UI.","selectAll":"Select All","selectNone":"Select None","tooMany":"(too many to list)","filterResults":"Filter values","apply":"Apply","cancel":"Cancel","totals":"Totals","vs":"vs","by":"by"},"derivedAttributes":{},"hiddenAttributes":[],"hiddenFromAggregators":[],"hiddenFromDragDrop":[],"menuLimit":500,"cols":["clientname","industry"],"rows":["country"],"vals":[],"rowOrder":"key_a_to_z","colOrder":"key_a_to_z","exclusions":{},"inclusions":{},"unusedAttrsVertical":85,"autoSortUnusedAttrs":false,"onRefresh":null,"showUI":true,"sorters":{},"rendererName":"Table With Subtotal","inclusionsInfo":{},"aggregatorName":"Count"}

在这里，我想提取字符串中以单词

cols:[]

开头的部分。方括号内的值将是动态的，并用双引号括起来。例如，在上面的例子中，我想要得到的字符串是：

“cols”：[“clientname”，“industry”]

。注意：我无法控制方括号内的值的数量

我编写了这个正则表达式：

（“cols”：\[（“\w*”，*\]）（cols:\[“\w*”\]*）

但很明显，我做错了什么。我需要一些提示来匹配方括号内的1个或多个值

试试这个！ Regex:

.*\"cols\":\[\"([^:]+)\"\]

输出：

---

谢谢您的格式化。我本应该小心规则的。没有借口。我知道。我想你需要做的是使用JSON解析器，不要再试图用正则表达式来混淆它。
