jmeter之jsonpath和beanshell联合使用

目的

下面返回的json字符串中，提取args的值中，最后一个逗号后面的字符串，比如下面就是提取：woLgrKts5s9Q4huajoCGHS

{"code":20000,"msg":"成功","data":{"total_page":1,"count":13,"current_page":1,"size":15,"results":[{"uuid":"MPgxSoq4wpqaTvePaQpEUU","title":"公共课协议","image":"https://oss.test.cn/vip/file/20220107113645iJ3u.png","icon":"","order":8,"redirect":{"args":"a5cLH6Xmk5vvPpCWsKLiSD,JS8Tr7SHH78FKwD6CTbMRD,woLgrKts5s9Q4huajoCGHS","tp":3}}]}}

实现

我们要提取的目标字符串是一个value字符串的一部分，所以，只用jsonpath不能一步到位，还需要beanshell对结果进行切割，然后获取到目标字符串

$.data.results[0].redirect.args

String s = "${args}";
log.info("============" + s);
String[] arr = s.split(",");
vars.put("args_last", arr[arr.length-1].trim());
log.info("-----------" + vars.get("args_last"));
