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

Answer 1

var Qiniu1 = new QiniuJsSDK()

var Qiniu2 = new QiniuJsSDK()

var uploader1= Qiniu1 .uploader({})

var uploader2= Qiniu2 .uploader({})
