只有当键"has_products“= true时，我才需要从JSON响应中提取值。能用千分尺提取吗？

Question

我的Json答复如下：

{  
   "id":2,
   "parent_id":1,
   "has_products":false,
   "has_categories":true,

有人能帮我吗？

假设要提取的值是id，则添加具有以下配置的JSON萃取器：

• 变量名:，将保存该值的变量的名称。
• JSON路径表达式: $.categories[?(@.has_products == true)].id
• 匹配号:如果要提取传递条件的所有id值，请使用 1 //使用-1。
• 默认值: NOT_FOUND

• 高级使用.json路径提取器-json计但是使用核心JMeter JSON抽取器而不是博客中提到的插件
