一个字段里的数据如下: [{"name":"地点","itemType":"input","itemId ":"217474","itemValue":"爵士鞋行门头上方"},{"name":"图片","itemType":"image","itemId ":"898808","itemValue":["https://aa.com/uploadfile/Pictures/2022/3/28/382c66a75a614768a48670697f85a132.jpg","https://aa.com/uploadfile/Pictures/2022/3/28/57cac58516714409a38bd1068eaea480.jpg"]},{"name":"整改时间","itemType":"time","itemId":"124470","itemValue":"2022/03/28 16:25"}] 用FR如何处理才能提取出相应的数据?我主要是想提取https:后面哪两个网址,但这个网址是不固定个数的,可能是1个也可能是3个4个。 |
