Question

说我有以下JSON：

{"MyPerson":{"Firstname":"First","Lastname":"Last","Where":{"Street":"Street","Number":15}},"AnotherComplexObject":{"Another":"Yes","Me":"True"},"Count":1,"Start":2}

我删除了开始{并结束}并获取：

"MyPerson":{"Firstname":"First","Lastname":"Last","Where":{"Street":"Street","Number":15}},"AnotherComplexObject":{"Another":"Yes","Me":"True"},"Count":1,"Start":2

现在，我将使用什么正则表达式来获取“复杂对象”，例如在JSON中我想得到这两个结果：

{"Firstname":"First","Lastname":"Last","Where":{"Street":"Street","Number":15}}
{"Another":"Yes","Me":"True"}

我最接近解决方案的是这个正则表达式{[^}]*}，但是该}结果无法选择"Number":15。
