避免完全匹配的正則表達式

-1

我想提取對象（如Regions和Countries）的id和type，其中available=true。我用正則表達式{"name":".+?","id":"(.+?)","type":"(.+?)","available":true。避免完全匹配的正則表達式

我得到一個從名稱開始的完整行... {other in the middle} ... available = true其中包括其他ID /名稱，即使在available=false也是如此。下面

使用[^「]''代替。+？' – hjpotter92

而是使用JSON解析器像https://github.com/stig/json-framework – hjpotter92

嗨..感謝..我得到了我想要的使用[^「] + – shett

最簡單的方案（沒有總重寫）

樣本數據可以是

{"name":"[^"]*","id":"([^"]*)","type":"([^"]*)","available":true,[^{}]*}

代替掃描的用於. - 任何字符，但換行符 - 掃描任何字符，但{或} - [^{}]。

See it here at regex101。

可以請你解釋我是如何工作的？ – shett

檢查regex101的說明。它非常徹底。 – ClasG

我建議去從JMeter 3.0發佈的JSON Path PostProcessor，因爲它更適合於使用JSON數據。

相關JSON路徑表達式是：

$..[?(@.available == true)].id
$..[?(@.available == true)].type
