七牛上传图片的问题

Question

如果我一个页面、有两个地方上传图片但是我想他们的key不同，要怎么才能分开不冲突呢，我现在的做法是创建两个文件

var uploader1= Qiniu.uploader({

'Key': function(up, file) {

            var now = new Date();

            var date = now.getFullYear()+((now.getMonth()+1)<10?"0":"")+(now.getMonth()+1)+(now.getDate()<10?"0":"")+now.getDate();

            return "topic/cover/"+date;

        },

})

var uploader2= Qiniu.uploader({

    'Key': function(up, file) {

            var now = new Date();

            var date = now.getFullYear()+((now.getMonth()+1)<10?"0":"")+(now.getMonth()+1)+(now.getDate()<10?"0":"")+now.getDate();

            return "topic/banner/"+date;

        },

    })

})

但是这样做为什么key会相同呢
