问了GPT，可能文化水平有限，得不到我需要的答案
以上有两个数组，data1的数组是从API得来的，数组内的对象是不固定的，可能是多个，但数组对象里的name是唯一的，不会重复，
data2数组里的对象也是不固定的，name可能会有重复
我需要根据以下条件，从data2里拿到我想要的数据
根据data1的数据,name为前提，每个key从data2筛选出最多3条数据，比如data1里的”油“，如果data2里存在，并且大于等于3，则跳过油，则这个对象从data2里拿到了0个对象，”米“在data2里只有一条，则从data2里取除去有”米“且status为1(优先)的两个随机对象，如果没有status为1的对象，则取status为0的对象,data1的”盐“在data2里有两个对象，则在data2里取除去”盐“的一个随机对象，以此类推..
根据上面例子,”油“从data2获取了0个对象，”米“从data2获取了2个对象，”盐“获取了1个对象，打印出来就是符合三个对象
