1、下载地址，及插件文档资料
https://jmeter-plugins.org/wiki/JSONPathExtractor/
json信息如下
{
???????"error_code": 0,
???????"stu_info": [
???????????????{
???????????????????????"id": 5047,
???????????????????????"name": "lw",
???????????????????????"sex": "男",
???????????????????????"age": 28,

???????????????????????"grade": "天蝎座",
???????????????????????"phone": "15512532946",
???????????????????????"gold": 1600
???????????????}
???????]
}
2、在http请求中添加json path extractor 或者 json extractor或者正则表达式提取器
3、json 插件的配置方式及正则表达式的配置方式
4、查看结果
5、json的使用方法
{ "store": { ???"book": [ ??????{ "category": "reference", ???????"author": "Nigel Rees", ???????"title": "Sayings of the Century", ???????"price": 8.95 ?????}, ?????{ "category": "fiction", ???????"author": "Evelyn Waugh", ???????"title": "Sword of Honour", ???????"price": 12.99 ?????}, ?????{ "category": "fiction", ???????"author": "Herman Melville", ???????"title": "Moby Dick", ???????"isbn": "0-553-21311-3", ???????"price": 8.99 ?????}, ?????{ "category": "fiction", ???????"author": "J.
