uniapp使用uviews上傳多張圖片，出現(xiàn)獲取的圖片路徑重復了，是因為放在了onchange中了，解決方法

    <u-upload :auto-upload="true" :action="action" :header="imgheader" :file-list="fileList"
                    @on-remove="delimg" max-count="9" @on-choose-complete="upimgchoose" :custom-btn="true" > 
          <view slot="addBtn" class="slot-btn" hover-class="slot-btn__hover" hover-stay-time="150">
                <u-icon name="photo" size="60"></u-icon>
          </view>
   </u-upload>

upimgchoose(lists, name) {
         this.imglist = lists

         // this.imglist = this.imglist.filter(item => item.url.startsWith('http://tmp/'))
         //為了添加的時候二次添加圖片，獲取的路徑和第一次添加的路徑不同，過濾第二次的路徑
         this.imglist = this.imglist.filter(item => item.url.startsWith('wxfile://tmp'))
         this.fupimg(this.imglist)
