javascript - 七牛上傳圖片的問題

Question

如果我一個頁面、有兩個地方上傳圖片但是我想他們的key不同，要怎麼才能分開不衝突呢，我現在的做法是創建兩個文件

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;
        },
    })
})

但是這樣做為什麼key會相同呢

Answer 1

key不同是指？

Answer 2

知道了，原來需要實例化

var Qiniu1 = new QiniuJsSDK()
var Qiniu2 = new QiniuJsSDK()
var uploader1= Qiniu1 .uploader({})
var uploader2= Qiniu2 .uploader({})
