fastjson - 将json对象转换成List集合

从接口response里拿出json格式的返回对象，转换成String类型

def data = JSONPath.read(responseString, '$.data') // responseString就是String类型的文本
//使用JSONPath.read方法需要import com.alibaba.fastjson.JSONPath

此时如果data是个数组时，返回类型是class com.alibaba.fastjson.JSONArray
如果data是一个普通数据节点，返回类型是class java.lang.String

对于JSONArray，可以将其存进List，对象类型是Video

List

Json format sample：

{
  "code":0,
  "message":"0",
  "ttl":1,
  "data":[
    {
      "aid":"672247475",
      "bvid":"BV1BU4y1a7ih",
      "typename":"日常",
      "title":"aaaa1",
      "subtitle":""
    },
    {
      "aid":"672247476",
      "bvid":"BV1BU4y1a7ih",
      "typename":"日常",
      "title":"aaaa2",
      "subtitle":""
    }]
}

以下类用于处理数组对象的格式

public class Video {
    
    public String aid;
    public String bvid;
    public String typename;
    public String title;
        public Video(String aid, String bvid, String typename, String title) {
          this.aid = aid;
          this.bvid = bvid;
          this.typename = typename;
          this.title = title;
    }
