{
"result": [
{
"puid": "21025318"
},
{
"puid": "21482682"
},
{
"puid": "21025345"
}
],
"state": 0
}

JSONPath.extract(str, "$.result[0,2].puid")报异常
java.lang.UnsupportedOperationException
at com.alibaba.fastjson.JSONPath$MultiIndexSegment.extract(JSONPath.java:2694)

使用JSONPath.eval(jsonObject, "$.result[0,2].puid") 正常
