Question

我有一个像这样的JSON文件：

我想在“坐标”的第一个右方括号（] ）之后找到能找到第一个右括号（} ）的正则表达式。因此，"coordinates" : [ ...]之后它将匹配第一个}。我跟着some regex tutorials在这里，但这对我目前的知识来说似乎有点过于复杂......

Answer 1

这是你描述的正则表达式：

"coordinates"[^]]*][^}]*\}

但是，在您的示例中， "coordinates" 之后的第一个右方括号之后的第一个右大括号也是"coordinates"之后的第一个右大括号，这使得正则表达式均匀更简单的：

"coordinates"[^}]*\}

如果您只想匹配大括号，请在它前面添加\K：

"coordinates"[^}]*\K\}

\K表示＆＃34;假装比赛真正在这里开始＆＃34;。

匹配值的（最后）封闭括号 - 正则表达式
