问题描述

环境信息

重现步骤

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertNotNull;

public class Issue113_Mutated_137 {

    @Test
    public void test() {
        String testJson2 = "{\"result\":[{\"puid\":\"21025318\"},{\"puid\":\"21482682\"},{\"puid\":\"21025345\"}],\"state\":0}";
        JSONArray result2 = (JSONArray) JSONPath.extract(testJson2, "$.result[0,2].puid");
        assertNotNull(result2);
        assertEquals("[\"21025318\",\"21025345\"]", result2.toJSONString());
    }
}

期待的正确结果

在Fastjson2-2.0.49中 测试正常
