json导入数据出错

[Davidyanlong]

{"data":{"list":[{"format":"2","length":1968,"name":"fff.png","ok":true,"size":"640x200","standard":false,"url":"https://img.alicdn.com/simba/img/TB1gsPeUCzqK1RjSZPxwu34tVXa.png"}]},"info":{"disableTime":false,"lockSla":false,"ok":true}}

导入这段json,也许数据中包括length，会产生1968个数据
